GENERAL DESCRIPTION

The CN63100 Controller accepts signals from a variety of temperature
sensors (thermocouple or RTD elements), while the CN63300 Controller
accepts either a 0 to 10 VDC or 0/4 to 20 mA DC input signal. Both controllers
precisely display the process, and provide an accurate output control signal
(time proportional or linear DC) to maintain a process at the desired control
point. The controllers’ comprehensive programming allows them to meet a
wide variety o f application requirements.

The controller can operate in the PID control mode for both heating and
cooling, with on-demand Auto-Tune, which will establish the tuning
constants. The PID tuning constants may be fine-tuned by the operator at any
time and then locked out from further modification. The controller employs a
unique overshoot suppression feature, which allows the quickest response
without excessive overshoot. Operation of the controller can be transferred to
manual mode, providing the operator with direct control of the output. The
controller may also be programmed to operate in the ON/OFF control mode
with adjustable hysteresis.

Dual 4-digit displays allow viewing of the process/temperature and
setpoint simultaneously. Front panel indicators inform the operator of the
controller and output status. The control output and the alarm outputs are
field replaceable on select models.

Optional alarm (s) can be configured to activate according to a variety of
actions (Absolute HI or LO, Deviation HI or LO, Band IN or OUT, and Heater
Current Break) with adjustable hysteresis. A standby feature suppresses the
alarm during power-up until the process stabilizes outside the alarm region.

Optional Main Linear DC output (10 V and 20 mA) can be used for control or
retransmission purposes. Programmable output update time reduces valve or
actuator activity. The output range can be scaled independent of the input range.

Optional Second Linear DC output (10 V or 20 mA) provides an
independent process retransmission, while the main Linear DC output is
being used for control. The output range can be scaled independent of the
input range.

A Remote Setpoint input (0/4 to 20 mA) allows for cascade control loops,
where tighter control quality is required; and allows for remotely driven
setpoint signal from computers or other similar equipment. Straightforward
end point scaling with independent filtering and local/remote transfer option
expands the controller’s flexibility.

The optional RS485 serial communication interface provides two-way
communication between a controller and other compatible equipment such as
a printer, PLC, HMI, or a host computer. In multipoint applications (up to
thirty-two), the address number of each controller on the line can be
programmed from 0 to 99. Data from the controller can be interrogated or
changed, and alarm output(s) may be reset by sending the proper command
code via serial communications.

The unit is constructed of a lightweight, high impact plastic case with a tinted
front panel. The front panel meets NEMA 4X/IP65 specifications when properly
installed. Multiple units can be stacked horizontally or vertically. Modern
surface-mount technology, extensive testing, plus high immunity to noise
interference makes the controller extremelyreliableinindustrialenvironments.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in
the manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

Do not use the controller to directly command motors, valves, or other
actuators not equipped with safeguards. To do so, can be potentially harmful
to persons or equipment in the event of a fault to the unit. An independent and
redundant temperature limit indicator with alarm outputs is strongly
recommended.

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

CAUTION: Risk of electric shock.

INSTALLATION DESCRIPTION

The controller meets NEMA 4X/IP65 requirements for
indoor use to provide a watertight seal in steel panels with a
minimum thickness of 0.09 inch, or aluminum panels with
a minimum thickness of 0.12 inch. The units are intended to
be mounted into an enclosed panel. It is designed so that the
units can be stacked horizontally or vertically (see Figure

1). The bezel assembly MUST be in place during
installation of the unit.

INSTRUCTIONS:

1. Prepare the panel cutout to the dimensions shown in

Figure 1, Panel Installation.

2. Remove the panel latch from the unit. Discard the

cardboard sleeve.

3. Carefully remove the center section of the panel gasket

and discard. Slide the panel gasket over the unit from the

rear, seating it against the lip at the front of the case.

4. Insert the unit into the panel cutout. While holding the

unit in place, push the panel latch over the rear of the

unit, engaging the tabs of the panel latch in the farthest

forward slot possible.

5. To achieve a proper seal, tighten the panel latch screws

evenly until the unit is snug in the panel, torquing the

screws to approximately 7 in-lbs (79 N-cm). Over

tightening can result in distortion of the panel, and

reduce the effectiveness of the seal.

Note: The installation location of the controller is important.

Be sure to keep it awayfrom heat sources (ovens, furnaces,

etc.), and away from direct contact with caustic vapors,

oils, steam, or any other process byproducts in which

exposure may affect proper operation.

Figure 1, Panel Installation

MULTIPLE UNIT STACKING

The controller is designed for close spacing of multiple units. Units can be
stacked either horizontally or vertically. For vertical stacking, install the
panel latch with the screws to the sides of the unit. For horizontal stacking, the
panel latch screws should be at the top and bottom of the unit. The minimum
spacing from center line to center line of units is 1.96" (49.8 mm). This
spacing is the same for vertical or horizontal stacking.

Note: When stacking units, provide adequate panel ventilation to ensurethat

the maximum operating temperature range is not exceeded.

Figure 2, Multiple Unit Stacking Horizontal Arrangement

Caution: Disconnect power to the unit and to the output

control circuits to eliminate the potential shock hazard
when removing the bezel assembly.

UNIT REMOVAL PROCEDURE

To remove a unit from the panel, first loosen the panel latch screws. Insert
flat blade screwdrivers between the latch and the case on either side of the
unit, so that the latches disengage from the grooves in the case. Push the unit
through the panel from the rear.

REMOVING BEZEL ASSEMBLY

The bezel assembly, shown in Figure 3, must be removed from the case to
replace the output board. To remove the bezel assembly, insert a flat blade
screwdriver into the pry slot on either side of the unit. Twist the screwdriver
handle until the unit is ejected enough to allow removal.

Figure 3, Bezel Assembly

Caution: The bezel assembly contains electronic circuits that can be damaged by

static electricity. Before removing the assembly, discharge static charge on
your body by touching an earth ground point. It is also important that the bezel
assembly be handled only by the bezel itself. Additionally, if it is necessary to
handle a circuitboard,be certain that hands arefree from dirt, oil, etc.,to avoid
circuit contamination that may lead to malfunction. If it becomes necessary to
ship the unit for repairs, place the unit in its case before shipping.

INSTALLING BEZEL ASSEMBLY

To install the bezel assembly, insert the assembly into the case until the
bezel is fully seated against the lip o f the case. Properly installing the bezel
assembly is necessary for watertight sealing.

CONNECTION DESCRIPTION

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are designed with a high degree of
immunity to Electromagnetic Interference (EMI), proper installation and
wiring methods must be followed to ensure compatibility in each application.
The type of the electrical noise, source or coupling method into a unit may be
different for various installations. Cable length, routing, and shield
termination are very important and can mean the difference between a
successful or troublesome installation. Listed are some EMI guidelines for a
successful installation in an industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected

to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield

connection should be made as short as possible. The connection point for

the shield depends somewhat upon the application. Listed below are the

recommended methods of connecting the shield, in order of their

effectiveness.

a. Connect the shield to earth ground (protective earth) at one end where

the unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually

when the noise source frequency is over 1 MHz.

3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors, feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be run through metal conduit that is

properly grounded. This is especially useful in applications where cable

runs are long and portable two-way radios are used in close proximity or if

the installation is near a commercial radio transmitter. Also, Signal or

Control cables within an enclosure should be routed as far away as possible

from contactors, control relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression
devices such as Ferrite Suppression Cores for signal and control cables is
effective. The following EMI suppression devices (or equivalent) are
recommended:
Fair-Rite part number 0443167251 (RLC part number FCOR0000)
Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize
radiated and conducted noise (EMI), some type of contact protection
network is normally installed across the load, the contacts or both. The
most effective location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal

oxide varistor (MOV) across an AC inductive load is very effective at
reducing EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a

transistor switch, care must be taken not to exceed the breakdown
voltage of the transistor when the load is switched. One of the most
effective ways is to place a diode across the inductive load. Most RLC
products with solid state outputs have internal zener diode protection.
However external diode protection at the load is always a good design
practice to limit EMI. Although the use of a snubber or varistor could be
used.

RLC part numbers: Snubber: SNUB0000

Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be
connected to an output common. This would cause EMI on the sensitive
input common, which could affect the instrument’s operation.

WIRING CONNECTIONS

After the unit has been mechanically mounted, it is ready to be wired. All
wiring connections are made to the rear screw terminals. When wiring the
unit, use the numbers on the label and those embossed on the back of the case,
to identify the position number with the proper function.

All conductors should meet voltage and current ratings for each terminal.
Also cabling should conform to appropriate standards of good installation,
local codes and regulations. It is recommended that power supplied to the unit
(AC or DC) be protected by a fuse or circuit breaker. Strip the wire, leaving
approximately 1/4" (6 mm) bare wire exposed (stranded wires should be
tinned with solder). Insert the wire under the clamping washer and tighten the
screw until the wire is clamped tightly.

Caution: Unused terminals are NOT to be used as tie points. Damage to the

controller may result if these terminals are used.

SIGNAL WIRING

Thermocouple (CN63100)

When connecting the
thermocouple, be certain that
the connections are clean and
tight, refer to Figure 4 for
terminal connections. If the
thermocouple probe cannot
be connected directly to the
controller, thermocouple wire
or thermocouple
extension-grade wire must be
used to extend the connection
points (copper wire does not
work). Always refer to the
thermocouple manufacturer’s
recommendations for
mounting, temperature range,
shielding, etc. For multi-probe temperature averaging applications, two or
more thermocouple probes may be connected to the controller (always use the
same type). Paralleling a single thermocouple to more than one controller is
not recommended. Generally, the red wire from the thermocouple is negative
and connected to the controller’s common.

Figure 4, Thermocouple Connection

RTD (CN63100)

When connecting the
RTD, be certain that the
connections are clean and
tight, refer to Figure 5 for
terminal connections. RTD
sensors have a higher
degree of accuracy and
stability than thermocouple
sensors. Most RTD sensors
available are the three wire
type. The third wire is a
sense lead f or canceling the
effects of lead resistance of
the probe. Four wire RTD
elements may be used by
leaving one of the sense
leads disconnected. Two wire RTD sensors may be used in either of two ways:

A) Attach the RTD to terminals #8 and #10. Install a copper sense wire of the

same wire gage as the RTD leads. Attach one end of the wire at the probe

and the other end to terminal #9. Complete lead wire compensation is

obtained. This is the preferred method.
B) Attach the RTD to terminals #8 and #10. Install a shorting wire between

terminals #9 and #10, as shown in Figure 5, RTD Connection. A

temperature offset error of 2.5°C/ohm of lead resistance exists. The error

may be compensated by programming a temperature offset.

Note: With extended cable runs, be sure the lead resistance is less than 15

ohms/lead. For thermocouple or RTD runs longer than 100 feet, convert the

signal to acurrent near the temperature probe.Currentor 20 mA loop signals

are less susceptible to noise and signal loss than long thermocouple or RTD

runs. By convertingthetemperature signal, the CN63300 canbe used in place

of a CN63100.

-5-

Figure 5, RTD Connection

Signal (CN63300)

When connecting signal
leads, be certain that the
connections are clean and
tight. For voltage signals, use
terminal #8 for common and
terminal #9 for signal. For
current signals, use terminal
#8 for common and terminal
#10 for signal. These
connections are shown in
Figure 6. Multicontroller
applications using the same
signal source are possible, by
connecting current signals in
series, and voltage signals in
parallel.

POWER WIRING

AC Power

Primary AC power is connected to terminals #11 and #12, labeled AC. To
reduce the chance of noise spikes entering the AC line and affecting the
controller, an AC feed separate from that of the load should be used to power
the controller. Be certain that the AC power to the controller is relatively
“clean” and within the variation limit. Connecting power from heavily loaded
circuits or circuits that also power loads that cycle on and off, (contacts,
relays, motors, etc.) should be avoided.

DC Power

DC power (18 to 36 VDC) is connected to terminals #11 and #12 labeled
DC+ and DC- respectively.

CAUTION: Observe proper polarity when connecting DC voltages.

Damage to the unit may occur if polarity is reversed.

CONTROL AND ALARM OUTPUTS

For CN63100 heating, cooling, and alarms, there are up to two types of
ON/OFF outputs. These outputs can be relay, or logic for control or alarm
purposes. Relay outputs can switch user applied AC or DC voltages.
Logic/SSR drive outputs supply power to external SSR power units. One
Logic/SSR Drive output can control up to four SSR power units at one time.
The CN63300 is only available with relay outputs. Terminal numbers for the
outputs and output types vary from model to model. Refer to the Rear
Terminal Assignment Tables or the label on the controller for the terminal
numbers corresponding to the model being wired.

Relay Connections

To prolong contact life and suppress electrical noise interference due to the
switching of inductive loads, it is good installation practice to install a snubber
across the contactor. Follow the manufacturer’s instructions for installation.

Note: Snubber leakage current can cause some electromechanical devices to be

held ON.

Relay Outputs:

Type: Form-A
Rating: 3 Amps @ 250 VAC or 30 VDC (resistive load).
Life Expectancy: 100,000 cycles at maximum load rating. (Decreasing

load and/or increasing cycle time, increases life expectancy).

REMOTE SETPOINT WIRING

Models with the Remote Setpoint option have two input terminals to
receive a 0 to 20 mA signal. Connect the Remote Setpoint signal to terminals
labeled #13 (+) and #14 (-), “2nd Input Option”. The common of this input is
isolated from input common, but is not isolated from the Linear DC output
commons. For proper operation, keep this common isolated from all other
controller commons.

MAIN LINEAR DC OUTPUT WIRING

Models with the Linear DC output option provide either a linear 10 V or a
linear 20 mA signal. The output range is selected by jumpers on the output
board. (See Linear DC Analog Output Jumper Selection, page 11). The
terminals are #1 (-) and #2 (+). The common of this output is isolated from
input common, but is not isolated from other commons. For proper operation,
keep this common isolated from all other controller commons.

SECOND LINEAR DC OUTPUT WIRING

Models with the Second Linear DC output option provide a conditioned
and scaled retransmitted signal output. The terminals are #13 (+) an d #14 (-).
The common of this output is isolated from the input common, but not from
the other commons. For proper operation, keep this common isolated from all
other controller commons.

USER INPUT WIRING

The use of shielded cable is recommended. Follow the EMC installation
guidelines for shield connection.

Terminal #6 is the User Input, which is programmable for a variety of
functions. Any form of mechanical switch may be connected to terminal #6
(USER INPUT) and terminal #8 (COMM.). Sinking open collector logic with
less than 0.7 V saturation and off-state leakage current of less than 1 μAmay
also be used.

SERIAL CONNECTIONS TO A HOST TERMINAL

Six controllers are used to monitor and control parts packaging machines
in a plant. The controllers are located at each machine in the production area
of the building. A communication line is run to an industrial computer located
in the production office.

Each controller is programmed for a different address and all are
programmed for the same baud rate and parity as the computer (ex. 9600
baud, parity even). An application p rogram is written by the user to send and
receive data from the units using the proper commands.

LINEAR DC ANALOG OUTPUT JUMPER SELECTION

(Main & Second)

The Linear Analog DC Output ranges are selectable for either voltage
(0-10 V) or current (0/4-20 mA). The main set of jumpers must correspond
with the configuration in Linear Output Range (ANAS) in the Output
Parameter Module (2-OP). The optional secondary set of jumpers must
correspond with the configuration in Second Linear DC Output Range (A2tP)
in the Second Linear DC Analog Output Module (8-A2). The jumpers are
accessible from the rear after removing the controller from the case. Dashed
lines show factory setting of 20 mA.

FRONT PANEL DESCRIPTION

The front panel bezel material is flame and scratch resistant, tinted plastic
that meets NEMA 4X/IP65 requirements, when properly installed.
Continuous exposure to direct sunlight may accelerate the aging process of
the bezel. The bezel should be cleaned only with a soft cloth and neutral soap
product. Do NOT use solvents. There are two 4-digit LED displays, a red
upper Main Display and a lower green Secondary Display.

There are up to six annunciators, with red backlighting, that illuminate to
inform the operator of the controller and output status. See Figure 11, Front
Panel, for a description of the annunciators.

Four front panel buttons are used to access diff erent modes and
parameters. The following is a description of each button.

Do NOT use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the

keypad of this unit.

BUTTON FUNCTIONS

D - In the Normal Display Mode, the

Display (D) button is used to

select one of the operational

parameters in the secondary

display. In other modes, pressing

the D button causes the controller

to exit (escape) directly to the

Normal Display Mode.
P - The Parameter (P) button is used

to access programming, enter the

change, and scroll through the

available parameters in any mode.
UP, DN - In the Normal Display

Mode, the Up/Down (L /M)

buttons can be used to directly

modify the setpoint value or

% output power (manual control

only), when viewed in the

secondary display.

Figure 11, Front Panel

-12-

INITIAL CONFIGURATION START-UP

CONTROLLER POWER-UP

Upon applying power, the controller delays input indication and control
action for five seconds to perform several self-diagnostic tests and to display
basic controller information. Initially, the controller illuminates both
displays and all annunciators to verify that all display elements are
functioning. The controller then displays the programmed input sensor type
in the main (top) display and the revision number of the controller’s operating
system software in the secondary (bottom) display. The controller checks for
correct internal operation and displays an error message (E-xx) if an internal
fault is detected. (See Troubleshooting, page 71, for further information).

Upon completion of this sequence, the controller begins displaying the
input value and updating the outputs based upon the control calculation.

PARAMETER CONFIGURATION OVERVIEW

The controller is programmed with certain parameter settings from the
factory. Factory settings are listed in parentheses in the various Configuration
of Parameters tables. In many cases, these settings must be changed to the
particulars of the application before proper operation can be started.

The controller is typically in the Normal Display Mode. When changes to
parameter configurations are needed, the P button is pressed. From the factory,
the controller will enter directly into the Unprotected Parameter Mode.
Continue to press the P button until CnFP appears in the bottom display. At this
time, press the Up arrow button and 1-In will appear in the bottom display. This
will be the Configuration Parameter Mode. This programming flow is shown in
the Front Panel Programming Chart. (If at any time during front panel
programming the D button is pressed, the controller will return to the Normal
Display Mode and the programming can be started over.)

In the Configuration Parameter Mode, the Up or Down arrow buttons can
be pressed to move to the desired Parameter Module. The P button is then
pressed to enter into that module. The main (top) display will be the parameter
and the secondary (bottom) display will be the parameter value. The Up or
Down arrow buttons are used to change the desired parameter value and the P
button enters the new value and moves to the next parameter.

The Setpoint value (lower display) is changed with the Up or Down arrow
buttons when it is selected in the Normal Display Mode.

PARAMETER CONFIGURATION BASIC START-UP

For basic start-up, it is important to verify or change Input Parameter
Module (1-IN) parameters tYPE and SCAL, and Output Parameter Module
(2-OP) parameter OPAC. For alarm and heat/cool set-up, it is important to
verify or change Alarms Parameter Module (4-AL) parameters ACt1, AL-1,
ACt2 and AL-2.

If the above Input Parameters or the input wiring connections are not
correct, then the main (top) display may display an error message or incorrect
value. Verify the input programming and wiring. (If incorrect display
continues refer to Troubleshooting, page 71.) All other parameter
configurations are important but will not prevent the controller from showing
a correct display.

PARAMETER CONFIGURATION FOR SERIAL START-UP

The parameter settings can be changed by the front panel button. For serial
communications set-up, it is important to check serial wiring and verify or
change Serial Parameter Module (6-SC) p arameters bAUd, ConF,s and Addr.
(See Serial Communications Interface, page 57, for more details.)

CONTROL START-UP

After verifying proper programming and system start-up, a controlling
method needs to be configured. For Manual Control or open loop, where the
control does not work from the setpoint or process feedback, see Manual
Control, page 46. For On / Off Control, set Proportional Band Prop to 0.0%
and see On / Off Control, page 47. The controller comes with factory setting
for PID Control. However, for optimum PID Control, several options exist
for configuring Proportional Band, Integral Time, and Derivative Time
parameters for specific applications.

a. Use controller’s built-in Auto-Tune feature (See Auto-Tune For PID

Control, page 50).

b. Use a manual tuning technique (See Manual Tuning For PID Control,

page 55).
c. Use a third party tuning software package.
d. Use values based on control loop experience, calculated values or values

from a similar process or previous controller.

UNPROTECTED PARAMETER MODE

The Unprotected Parameter Mode is accessed by pressing the P button
from the Normal Display Mode with Program Disable inactive. While in this
mode, the operator has access to the most commonly modified controller
parameters by pressing the P button. The temperature or scaled process value
is displayed in the main (top) display. The parameter display will appear with
the corresponding range and units in the secondary (bottom) display.

To modify values, use the Up or Down arrows while the parameter is
displayed. The controller responds to the new values immediately, however,
the change is not committed to non-volatile memory until the controller is
returned to the Normal Display Mode. If power loss occurred before
returning to the Normal Display Mode, the new values must be entered again.

To gain access to the Configuration Parameter Modules, continue to CnFP
and press the Up arrow. These modules allow access to the fundamental
set-up parameters of the controller. When the program list has been scrolled
through, or the D button is pressed, the controller displays “End” and returns
to the normal display mode. The unit automatically returns to the Normal

CONFIGURATION PARAMETER MODE

The Configuration Parameter Mode is accessed by pressing the Up button
from CnFP in the Unprotected Parameter Mode. While in this mode, the
various Configuration Modules can be displayed by pressing the Up or Down
buttons. The process value (after initial setup) will be displayed in the main
(top) display. The Configuration Module will appear alternating with CnFP
in the secondary (bottom) display.

To access a Configuration Module, press the P button when the desired
Configuration Module is displayed. The parameters of that Configuration
Module can be accessed by pressing the P button. (The module’s parameters
are listed in the appropriate Configuration Module table in this section with
configuration parameter explanations beginning on page 30.) To modify
ranges and units, use the Up or Down arrows while the parameter is displayed.
The controller responds to the new values after the P button is pressed,
however, the change is not committed to permanent memory until the
controller is returned to the Normal Display Mode. If power loss occurred
before returning to the Normal Display Mode, the new values must be entered
again. Whenever the D button is pressed, End will momentarily appear and
the controller will return to the Normal Display Mode. At the end of each
module, the controller will go to CnFP no. Pressing the Up or Down arrows
will continue in Configuration Parameter Mode and pressing the P will return
to the Normal Display Mode.

Unless specified, the parameters, ranges, units and factory settings are the
same for CN63100 and CN63300 controllers. Parameters that are model
number or program dependent will only be displayed when the appropriate
options are installed or programmed. Some parameters are accessible but may
not be applicable for the chosen output control mode type.

CONFIGURATION PARAMETER EXPLANATIONS

Input Parameter Module (1- IN) CN63100 Models

The controller has several input set-up parameters that must be

programmed prior to setting any other controller parameters.

Input Type (tYPE)

Select from the list of various thermocouple and RTD sensors.
The following is a list of the possible sensors:

tc-t Type T TC
tc-E Type E TC
tc-J Type J TC
tc-k Type K TC
tc-r Type R TC
tc-S Type S TC
tc-b Type B TC
tc-N Type N TC
LIN Linear mV display
r385 385 curve RTD
r392 392 curve RTD
rLIN Linear ohms display

Temperature Scale (SCAL)

Select either degrees Fahrenheit (F) or degrees Celsius (C).

If changed, be sure to check all parameters.

Temperature Resolution (dCPt)

Select either 1 or 0.1 degree resolution.

If changed, be sure to check all parameters.

Digital Input Filtering and Display Update Rate (FLtr)

Select the relative degree of input signal filtering and display update rate.
The filter is an adaptive digital filter that discriminates between
measurement noise and actual process changes. Therefore, the influence on

step response time is minimal. If the signal is varying too greatly due to
measurement noise, increase the filter v alue. Additionally, with large
derivative times, control action may be too unstable for accurate control.
Increase the filter value. Conversely, if the fastest controller response is
desired, decrease the f ilter value.

The Auto-tune procedure sets the filter value appropriate to the process
characteristics. Also see Output Power Dampening parameter (OPdP), page
35, for filtering the output.

Fltr- 0 to 4

0 = least input filtering
3 = most input filtering
4 = most input filtering and slower (500 msec) display update rate

(outputs update at 100 msec rate)

Input Sensor Correction Constant (SHFt)

If the controller temperature disagrees with a reference temperature
instrument or if the temperature sensor has a known calibration, the controller
temperature can be compensated by a correction offset (SHFt).

SHFt - -999 to 9999
The following equation expresses the relationship:
Desired Display Temp = (Controller Temp) + SHFt

Example 1: The controller reads 293°F while a reference instrument indicates

300°F. A SHFt value of +7°F corrects the controller indication to match the
reference.

Setpoint Limit Values (SPLO & SPHI)

The controller has programmable high and low setpoint limit values to

restrict the setting range of the setpoint. Set the limit values so that the
temperature setpoint value cannot be set outside the safe operating area of
the process.

SPLO - -999 to 9999

SPHI - -999 to 9999

-30-

Setpoint Ramp Rate (SPrP)

The setpoint can be programmed to ramp independent of the controller’s
display resolution. The setpoint ramp feature can reduce thermal shock to the
process, reduce temperature overshoot on start-up or setpoint changes, or
ramp the process at a controlled rate.

SPrP - 0.0 to 999.9 degrees/minute

A ramp value of zero disables setpoint ramping, allowing the controller to
stabilize as fast as possible to the new setpoint. If the user input is
programmed for setpoint ramp, it affects the enabling and disabling of
setpoint ramping. Setpoint ramping is initiated on power-up or when the
setpoint value is changed. Active setpoint ramping is indicated by the left
most decimal point flashing in the main display.

Figure 12, Setpoint Ramp Rate

Once the ramping setpoint reaches the target setpoint, the setpoint ramp
rate disengages until the setpoint is changed again. If the ramp value is
changed during ramping, the new ramp rate takes effect. If the setpoint is
ramping prior to invoking Auto-Tune, the ramping is suspended during
Auto-Tune and then resumed afterward using the current temperature as a
starting value. Deviation and band alarms are relative to the target setpoint,
not the ramping setpoint.

The Remote Setpoint input is also controlled by the setpoint ramp feature.
In situations where the remote setpoint must be rate controlled, this parameter
can be used to slowly increment (or decrement) the signal to its final value.
The target value, not the instantaneous ramp value, is displayed. Setpoint
ramp indication is disabled during remote setpoint ramping.

Note: Depending on the thermal characteristics of the process, the process

temperature may not track the programmed setpoint rate.

User Input (InPt)

The user input may be programmed to perform a variety of controller
functions. The input must be in its active state for 120 msec minimum to
perform the function. A function is performed when the User Input,
(Terminal 6) is pulled low to common (Terminal 8).

Note: Do not tie the commons of multiple units to a single switch. Use either a

multiple pole switch for ganged operation or a single switch for each unit.

Note: “Low Level” is switch closed.

“High Level” is switch open.

PLOC - Program Lock. A low level enables the program disable function

which places the unit in the Protected Parameter Mode.

ILOC - Integral Action Lock. A low level disables the integral action of the

PID computation. A high level resumes the integral action.

trnF - Auto/Manual Transfer. A negative transition places the unit in the

manual (user) mode and a positive transition places the unit in the

automatic operating mode. The output is “bumpless” when transferring to

either operating mode.
SPrP - Setpoint Ramp. A low level terminates setpoint ramping and the

controller operates at the target setpoint. Terminating setpoint ramping is

the same as setting the ramp rate to zero (SPrP = 0.0). A high level enables

the programmed setpoint ramp rate.
ALrS - Alarm Reset. On models with alarms, a low level resets any active

alarm(s) to their inactive state as long as the user input is low.
SP2 - Setpoint 1/ Setpoint 2 Select. On models with Second Setpoint, a low

level selects setpoint 2. A high level selects setpoint 1.

SPSL or RSP - Local/Remote Select. On models with Secondary Analog

Input, a negative transition engages Remote Setpoint operation and a
positive transition engages Local Setpoint operation. The response of the
controller to the setpoint transfer is set by the setpoint transfer parameter
“trnF”, under “ 7-rS” or “7-n2” module.

Prnt - Print Request. On models with Serial Communications, a low level

transmits the print option selected in the Serial Communications Module
(6-SC). If the user input is held low, after the printing is complete, another
request is issued.

Input Parameter Module (1- In) CN63300 models

The controller has several input set-up parameters that must be

programmed prior to setting any other controller parameters.

Input Type (tYPE)

Select the signal input type: Voltage (VOLt), or Current (Curr). The signal

input terminal for voltage is #9 and for current is #10. Common is #8.

Decimal Point Position (dCPt)

Select the desired decimal point position for the scaled display. The
selected decimal point position appears in the following parameters; rnd,
dSP1, dSP2, SPLO, SPHI, SP, AL1, AL2, db-2, AHYS, and CHYS.

0

0.0

0.00

0.000

Rounding Increment ( rnd)

Rounding values other than “ 1” causes the scaled number to ‘round’ to the
nearest rounding increment selected (i.e.. rounding of ‘5’ causes ‘122’ to
round to ‘120’ and ‘123’ to round to ‘125’). If the process is inherently jittery,
the display value may be rounded to a higher value than “1”. If the range of the
process exceeds the required resolution, (ex. 0-1000 PSI, but only 10 PSI
resolution required), a rounding increment o f 10 will effectively make the
display more stable.

This programming step is usually used in conjunction with programmable
digital filtering to help stabilize display readings. (If display stability appears
to be a problem and the sacrifice in display resolution is unacceptable,
program higher levels of digital filtering or increase the level of process
dampening.) Rounding increments of 10, 20, 50, and 100 may also be used to
add “dummy zeroes” to the scaled readings, as desired.

1
2
5
10
20
50
100

The rounding increment is for the controller’s display only and does not
affect (improve or degrade) the control accuracy of the unit.

Digital Input Filtering and Display Update Rate (FLtr)

Select the relative degree of input signal filtering and display update rate.
The filter is an adaptive digital filter that discriminates between
measurement noise and actual process changes. Therefore, the influence on
step response time is minimal. If the signal is varying too greatly due to
measurement noise, increase the filter v alue. Additionally, with large
derivative times, control action may be too unstable for accurate control.
Increase the filter value. Conversely, if the fastest controller response is
desired, decrease the f ilter value.

The Auto-tune procedure sets the filter value appropriate to the process
characteristics. See Output Power Dampening parameter (OPdP), page 35,
for filtering the output.

Fltr- 0 to 4

0 = least input filtering
3 = most input filtering
4 = most input filtering and slower (2/sec) display update rate

(outputs update at 10/sec rate)

Scaling Points

Prior to installing and operating the controller, it may be necessary to
change the scaling to suit the display units particular to the application.
Although the unit has been programmed at the factory, the scaling will
generally have to be changed.

The controller is unique in that two different scaling methods are available.
The two scaling procedures are similar in that the operator keys in the display
values and either keys in or applies a
signal value that corresponds to
those scaling points. The location of
the scaling points should be near the
process end limits, for the best
possible accuracy.

Once these values are
programmed (coordinates on a
graph), the indicator calculates the
slope and intercept of the
signal/display graph automatically.
No span/zero interaction occurs,
making scaling a one-pass exercise.

-32-

Figure 13, Scaling Points

Before programming the indicator, it is advised to organize all the data for

the programming steps to avoid possible confusion.

To scale the indicator, two signal values and two display values that
correspond to the signal values must be known. These four values are used to
complete the scaling operation. An example is listed below:

Scaling Point #1 Scaling Point #2

0.0% @ 4.00 mA & 100.0% @ 20.00 mA

Reverse acting indication can be accomplished by either reversing the two
signal points or the display value points, but not both. If both are reversed,
then forward (normal) acting indication will occur. In either case, do not
reverse the input wires to correct the action.

Display Values (dSP1 & dSP2)

Key-in the display value for scaling point one and scaling point two.

dSP1 -999 to 9999 (Ex. 0.0%)
dSP2 -999 to 9999 (Ex. 100.0%)

Signal Input Values (INP1 & INP2)

The signal input value can either be keyed in via the front panel buttons or
an input signal can be applied to the appropriate signal input terminals. When
entering the signal input parameter, the unit is in the key-in mode.

Key-in Method

Key-in the signal value for scaling point one and scaling point two.

INP1 -999 to 9999 (Ex. 0.00 VDC or 4.00 mA DC)
INP2 -999 to 9999 (Ex. 10.00 VDC or 20.00 mA DC)

Signal Input Method

To change to the apply signal method press the D button. Front panel
annunciators %P and DV will flash, and the display indicates the signal value
applied to the input terminals. The unit can be toggled to the key-in method by
pressing the D button again.

Signal Range Display Range

4.00 to 20.0 mA DC 0.00 to 20.00

0.00 to 10.00 VDC 0.00 to 10.00

When the desired value is indicated on the display, press the P button to
store the value and advance to the next parameter.

Setpoint Limit Values (SPLO & SPHI)

The controller has programmable high and low setpoint limit values to
restrict the setting range of the setpoint. Set the limit values so that the
setpoint value cannot be set outside the safe operating area of the process. On
models equipped with Second Analog Input, configured as a Remote
Setpoint, the Remote Setpoint reading is also restricted to these limits.

SPLO - -999 to 9999

SPHI - -999 to 9999

Setpoint Ramp Rate (SPrP)

The setpoint can be programmed to ramp independent of the controller’s
decimal point position and rounding increment. The setpoint ramp rate can
reduce sudden shock to the process, reduce overshoot on start-up or setpoint
changes, or ramp the process at a controlled rate.

SPrP - 1 to 9999 units/minute

Note: Defined here, a unit is the LSD of the display, regardless of decimal point

position.

A ramp value of zero disables setpoint ramping. If the optional user input is
programmed for setpoint ramp, it affects the enabling and disabling of
setpoint ramping. Setpoint ramping is initiated on power-up or when the
setpoint value is changed. Active Setpoint Ramping is indicated by the left
most decimal point flashing in the main display.

Figure 14, Setpoint Ramp Rate

-33-

Once the ramping setpoint reaches the target setpoint, the setpoint ramp
rate disengages until the setpoint is changed again. If the ramp value is
changed during ramping, the new ramp rate takes effect. If the setpoint is
ramping prior to invoking Auto-Tune, the ramping is suspended during
Auto-Tune and then resumed afterward using the current display as a starting
value. Deviation and band alarms are relative to the target setpoint, not the
ramping setpoint.

The Remote Setpoint input is also controlled by the setpoint ramp feature.
In situations where the remote setpoint must be rate controlled, this parameter
can be used to slowly increment (or decrement) the signal to its final value.
The target value, not the instantaneous ramp value, is displayed. Setpoint
ramp indication is disabled during remote setpoint ramping.

Note: Depending on the ramp rate relative to the process dynamics, the actual

scaled process value may not track the ramping setpoint value.

User Input (InPt)

The user input may be programmed to perform a variety of controller
functions. The input must be in its active state for 120 msec minimum to
perform the function. A function is performed when the User Input,
(Terminal 6) is pulled low to common (Terminal 8).

Note: Do not tie the commons of multiple units to a single switch. Use either a

multiple pole switch for ganged operation or a single switch for each unit.

Note: “Low Level” is switch closed.

“High Level” is switch open.

PLOC - Program Lock. A low level enables the program disable function

which places the unit in the Protected Parameter Mode.

ILOC - Integral Action Lock. A low level disables the integral action of the

PID computation. A high level resumes the integral action.

trnF - Auto/Manual Transfer. A negative transition places the unit in the

manual (user) mode and a positive transition places the unit in the

automatic operating mode. The output is “bumpless” when transferring to

either operating mode.
SPrP - Setpoint Ramp. A low level terminates setpoint ramping and the

controller operates at the target setpoint. Terminating setpoint ramping is

the same as setting the ramp rate to zero (SPrP = 0.0). A high level enables

the programmed setpoint ramp rate.

ALrS - Alarm Reset. On models with alarms, a low level resets any active

alarm(s) to their inactive state as long as the user input is low.

SP2 - Setpoint 1/ Setpoint 2 Select. On models with Second Setpoint, a low

level selects setpoint 2. A high level selects setpoint 1.

SPSL or RSP - Local/Remote Select. On models with Secondary Analog

Input, a negative transition engages Remote Setpoint operation and a
positive transition engages Local Setpoint operation. The response of the
controller to the setpoint transfer is set by the setpoint transfer parameter
“trnF”, under “ 7-n2” module.

PrNt - Print Request. On models with Serial Communications, a low level

transmits the print option selected in the Serial Communications Module
(6-SC). If the user input is held low, after the printing is complete, another
request is issued.

-34-

Output Parameter Module (2-OP)

The controller has parameters that affect how the main control output (O1)
and Main Linear DC output control signal responds to temperature changes
and sensor failures.

Time Proportioning Cycle Time (CYCt)

The selection of cycle time depends on the time constant of the process and
the type of output used.

CYCt - 0 to 250 seconds

For best control, a cycle time equal to 1/10 of the process time constant, or
less is recommended; longer cycle times could degrade temperature control,
and shorter cycle times provide little benefit at the expense of shortened relay
life. When using a Logic/SSR drive output with the SSR Power Unit, a
relatively short cycle time may be selected.

A setting of zero keeps the main control output and front panel indicator
off. This is useful if using the linear DC output signal for control. On some
models, output (O1) can be configured as an alarm output ACt1 under
Module “4-AL”.

Output Control Action (OPAC)

For heat and cool applications, the main output (O1) is normally used for
heating (reverse acting) and the optional cooling output (O2) is normally used
for cooling (direct acting).

OPAC - rEv (Reverse acting)

drct (Direct acting)

If O2 (cooling) is not used, then the action can be reverse or direct acting.
When used for control output, the Main Linear DC output operation is
affected by this parameter.

Output Power Limits (OPLO & OPHI)

Enter the safe output power limits for the process. These parameters may
also be used to limit the minimum and maximum controller power due to
process disturbances or setpoint changes, to reduce overshoots b y limiting
the process approach level.

OPLO & OPHI - 0 to 100%

If the cooling output is selected, the limits range from:

OPLO & OPHI - -100 to 100%

With Alarm 2 selected for cooling, the Lower Limit can be set to less than
0% to limit maximum cooling or set to greater than 0% to limit minimum
heating. Set the High Limit to less than 0% to limit minimum cooling or
greater than 0% to limit maximum heating. When controlling power in the
manual control mode, the output power limits do not take effect.

Sensor Fail Power Level (OPFL) CN63100 only

If a failed sensor is detected, the control output(s) default to a preset power
output.

OPFL - 0% (O1 output full “off”) to 100% (O1 output full “on”)

If Alarm 2 is selected for cooling , the range is extended from:

OPFL - -100% to +100%

At 0% both outputs are off, at 100% O1 is on and O2 is off, and at -100% O2
is on and O1 is off. The alarm outputs are up-scale drive (+9999) with an open
sensor, and down-scale drive (-9 999) with a shorted sensor (RTD only),
independent of this setting. Manual Control overrides OPFL.

Output Power Dampening Filtering Time (OPdP)

The output power calculated by the PID controller can be dampened
(filtered) to reduce the controller output activity. Those processes with high
gain and/or derivative times, or those processes with a relatively high noise
content, can benefit f rom the dampening action.

OPdP - 0 to 250 seconds

The dampening parameter is expressed as a time constant in seconds.
Increasing the value increases the dampening or filtering effect. A value of
zero disables output power dampening. The amount of dampening to be used
depends primarily on the response time of the process and the amount of final
actuator activity desired. Generally, dampening times in the range of 1/20 to
1/50 of the controller’s integral time (or process time constant) prove to be
effective. Dampening times longer than these may cause controller instability
due to the added lag effect of too much filtering.

In the case where a relatively high dampening time is desired, the
controller’s proportional band may be increased to restore an adequate
stability margin. The Auto-tune procedure of the controller sets the
dampening value appropriate to the characteristics of the process.

-35-

ON/OFF Control Hysteresis (CHYS)

The controller can be placed in the ON/OFF control mode by setting the
proportional band to 0.0%. The control hysteresis value affects only the
control outputs. Alarms have a separate hysteresis setting. See ON/OFF
Control, page 47, for more details.

CHYS - 1 to 250

The h ysteresis band should be set to a minimum value to eliminate output
chatter at the setpoint. Generally, 2 to 5 is sufficient for this purpose. Set the
hysteresis band to factory setting prior to invoking Auto-Tune. After
Auto-Tune, the hysteresis band has no effect on PID Control.

Auto-Tune Code (tcod)

Prior to invoking Auto-Tune, the Auto-Tune code should be set to achieve
the desired dampening level under PID Control. After Auto-Tune is complete,
changes to “tcod” parameter have no effect until Auto-Tune is restarted. When
set to 0, this yields the fastest process response with possible overshoot. A
setting of 2 yields the slowest response with the least amount of overshoot.
Dampening codes of 0 or 1 are recommended for most thermal processes.

Main Linear DC Output Range (ANtP) (Optional)

Select the type of output range:

0-10 = 0 to 10 V
0-20 = 0 to 20 mA
4-20 = 4 to 20 mA

The linear DC output range jumper must be set to match the range selected.
See Linear DC Output Jumper Selection, page 11. The linear DC output can
be re-calibrated to provide up to 5% of over range operation. See Main or
Second Linear DC Analog Output Calibration, page 69.

Main Linear DC Output Source (ANAS) (Optional)

The output can be programmed to transmit one of the below variables:

OP - Output Power % control
INP - Temperature retransmission
SP - Setpoint (local or remote) retransmission

For Linear DC Output control, the main output (O1) can be disabled by
setting the Cycle Time (CYCt) to 0 in Output Parameter 2-OP or configuring
it as an alarm in Alarm 1 Action (ACt1) in Alarm Parameter 4-AL. For
heat/cool with 4 to 20 mA control applications, the heat (0 to 100%) will be 12
to 20 mA and the cool (-100 to 0%) will be 4 to 12 mA. Notice that 0% (no heat
or cool) is 12 mA.

Main Linear DC Update Time (ANUt) (Optional)

To reduce excess valve actuator, or pen recorder activity, the update time
of the linear output can be set over the range of 0.1 to 250 seconds. A value of
0 seconds results in an update time of 0.1 second.

Main Linear DC Output Scaling Points (ANLO, ANHl) (Optional)

The output is scaled based on the Output Source (ANAS) display by use of
low and high scaling parameters. Reverse acting output is possible by
reversing the scaling points.

Figure 15, Auto-Tune Code

ANLO – Display value that corresponds to 0 V, 0 mA, or 4 mA as

selected.

ANHI – Display value that corresponds to 10 V or 20 mA as

selected.

-36-

Lockouts Parameter Module (3-LC)

The controller can be programmed to limit operator access to various
parameters, control modes, and display contents. The configuration of the
lockouts is grouped into three sections: Lower Display Lockouts, Protected
Mode Lockouts and Hidden Mode Lockouts.

Lower Display Lockouts (SP, OP, dEv, UdSP and bdSP)

The contents of the secondary display can be changed in the Normal
Display Mode by successively pressing the D button. This action scrolls
through the possible display parameters, when enabled. If all parameters are
settolock“LOC”,pressDtoblankthedisplay.

The parameters can be set for one of the following:

LOC (Lockout) – Prevents the parameter from appearing in the

rEd (Read only) – Parameter appears, but cannot be modified.
Ent (Entry) – Parameter appears and can be modified.

The lower display content possibilities are:

SP – Setpoint Value
OP – % Output Power
dEv – Setpoint Deviation
UdSP – Temperature Units (CN63100)
bdSP – Blank Display (CN63300)

Note: If a parameter is active in the lower display and is then subsequently

locked out, press “D” once in the Normal Display Mode to removeit from the

display.

Protected Mode Lockouts (CodE, PId, and AL)

The protected mode is active when program disable is active. The
parametersin the protected mode can be set for one of the following modes:

LOC (Lockout) – Prevents the parameter from appearing in the

rEd (Read only) – Parameter appears, but cannot be modified.
Ent (Entry) – Parameter appears and can be modified.

protected mode.

The code number allows access to the unprotected mode. To enter the
unprotected mode from the protected mode, the code number entered must
match the code number entered here. See Front Panel Program Disable, page
16, for a description of the various program access levels.

CodE – 0 to 250
PId – Permits access to the main PID parameters.
AL – Permits access to the alarm value(s).

Hidden Mode Lockouts (ALrS, SPSL, trnF, and tUNE )

The hidden mode is accessible f rom the Normal Display Mode by pressing
and holding the P button for three seconds. The parameters can be set for:

LOC (Lockout) – Prevents the parameter from appearing in the

ENbL (Enable) – Allows operator to perform the selected hidden

The functions available in the hidden mode are accessible independent of
the status of program disable.

ALrS – Reset (override) the alarm output(s).
SPSL – SP1/SP2/Remote setpoint selection.
trnF – Select Automatic or Manual operation.
tUNE – Invoke or cancel Auto-Tune.

**

** Model Number Dependent.

-37-

Alarm Parameter Module (4-AL) (Optional)

The controller may be equipped with one or two optional alarms. On some
models alarm output #1 is the same output as main control O1. In this case, the
output is either programmed f or the main output control function (O1) or as an
alarm function (A1). This is set by alarm #1 action parameter (Act1).

If heat is selected, the remaining Alarm 1 parameters do not appear.

To enable the cooling output of the controller, select CooL for Alarm 2
action (Act2). The controller then utilizes the alarm 2 output as the cooling
output (O2). Front panel annunciator A2 illuminates whenever the cooling
output is on. See Cooling Output Module (5-O2), page 42, for configuration
of the cooling output.

If cooling is selected, the remaining Alarm 2 parameters do not appear.

Alarm Action (Act1, Act2)

Note: When deviation low-acting with positive alarm value (d-LO), deviation

high-acting with negative value (d-HI), or Band inside-acting (b-IN) is

selected for the alarm action, theindicator is “OFF” whenthe alarm output

is “ON”.

Caution: Inapplications where equipmentor material damage,or risk

to personnel due to controller malfunction could occur, an
independent and redundant temperature limit indicator with alarm
outputs is strongly recommended. The indicators should have input
sensors and AC power feeds independent from theother equipment.

The configuration options of the alarm output are model dependent.

(Act1) - Alarm #1 (Act2) Alarm #2
A-HI Absolute High Acting A-HI Absolute High Acting
A-LO Absolute Low Acting A-LO Absolute Low Acting
d-HI Deviation High Acting d-HI Deviation High Acting

Note: Deviation and band type alarms track both local and remote setpoint.

Alarm Action Figures

The alarm action figures describe the status of the alarm output and the
front panel indicator for various over/under temperature conditions. The
alarm output wave form is shown with the output in the automatic reset mode.

Note: Select the alarm action with care. In some configurations, the front panel

indicator (LED) might be “OFF” while the output is “ON”.

-39-

-40-

Alarm Reset (rSt1, rSt2)

Each alarm reset action may be independently configured.

LAtC - Latched
Auto - Automatic

Latched alarms require operator action to reset the alarm condition. The
front panel buttons can be used to reset an alarm when the controller is in the
Hidden Function Mode (See page 19). An alarm condition may also be reset
via the user input.

Automatic reset alarms are reset by the controller when the alarm condition
clears. Figure 16, Alarm Reset Sequence, depicts the reset actions.

Figure 16, Alarm Reset Sequence

Alarm Standby Delay (Stb1, Stb2)

The alarm(s) may be independently configured to exhibit a power-on,
standby delay which suppresses the alarm output from turning “ ON” until the
temperature first stabilizes outside the alarm region. After this condition is
satisfied, the alarm standby delay is canceled and the alarm triggers normally,
until the next controller power-on. This feature also works for deviation and
band alarms when the setpoint is changed via keypad. This action suppresses
“nuisance” alarms. Figure 17, Alarm Standby Delay Sequence, depicts a
typical operation sequence.

Figure 17, Alarm Standby Delay Sequence

Alarm Value (AL-1, AL-2)

The alarm values are either absolute (absolute alarms) or relative to the
setpoint value (deviation and band alarms). An absolute alarm value is the value
that is entered. A relative alarm value is offset from the temperature setpoint
value by the amount entered and tracks the setpoint value as it is changed.

AL-1 and AL-2 - -999 to 9999

If the alarm action is set as a Band Alarm, then only a positive value can be
entered.

Alarm Hysteresis (AHYS)

The alarm value(s) have a programmable hysteresis band to prevent alarm
output chatter near the alarm trigger point. The hysteresis value should be set to
eliminate this effect. A value of 2 to 5 is usually sufficient for most applications.
A single alarm hysteresis value applies to both alarms. See the Alarm Action
Figures, page 39, for the effect of hysteresis on the various alarm types.

AHYS - 1 to 250

-41-

Cooling Parameters Module (5-02) (Optional)

The cooling output (O2) is software selectable with dual alarm models (For
the CN63300, this is referred to as the Second Control Output). This output
operates as an independent cooling output for systems that use heating and
cooling. To enter the Cooling Output Module, the cooling output of the
controller must first be selected in Alarm Module (4-AL). When cooling is
selected, alarm 2 is used for the cooling output.

The front panel indicator A2 illuminates when the cooling output (O2) is
on. Cooling output power is defined as ranging from -100% (full cooling) to
0% (no cooling, unless a heat-cool band overlap is used). See Output Power
Limits in Module 2 for maximum and minimum settings. The same PID
values control both heat and cool.

Cooling Output Cycle Time (CYC2)

A value of 0 turns off the cooling output, independent of cooling power
demand.

CYC2 - 0 to 250 seconds

Cooling Relative Gain (GAn2)

This parameter defines the gain of the cooling band relative to the heating
band. A value of 0.0 places the cooling output into ON/OFF Control mode
with the ON/OFF Control Hysteresis (CHYS) in Output Parameter Module
(2-OP) becoming the cooling output hysteresis. This may be done
independent of the main output control mode (PID or ON/OFF). Relative gain
is generally set to balance the effects of cooling to that of heating for best
control. Figures 18, 19, & 20, Heat/Cool Operation, illustrate the effect of
different gains.

GAN2 - 0.0 to 10.0

Heat and Cool Overlap/Deadband (db-2)

This parameter defines the area in which both heating and cooling are
active (negative value) or the deadband area between the bands (positive
value). The parameter units are degrees or tenth’s o f degrees (depending on
system resolution). If a heat/cool overlap is specified, the displayed percent
output power is the sum of the heat power (O1) and the cool power (O2).

db-2 - -999 to 9999

When the Cooling Relative Gain is set to zero for ON/OFF Control mode,
this parameter should only be set to a positive value or zero. The Heat/Cool
Operation Figures illustrate the effects of different deadbands.

Figure 18, Heat/Cool Operation (db=0)

Figure 19, Heat/Cool Operation (db>0)

When using the cooling output, observe the controlled temperature
characteristics. If the temperature remains above setpoint with a sluggish
return, increase the cooling gain. Similarly, if the temperature drops too

-42-

sharply with an overall saw-tooth pattern, decrease the cooling gain. Alter the
heat-cool overlap until a smooth response in the controlled temperature is
observed during band transition.

Figure 20, Heat/Cool Operation (db<0)

Serial Communications Module (6-SC) (Optional)

Unless controller serial configurations match those of the host
communicating device, front panel serial parameter changing is needed for
communication. Baud rate and character frame must be the same as the other
communicating device. The controller address is the unique node address for
multiple controllers applications. (See Serial Communications Interface,
page 57, for further explanations.)

Baud Rate (bAUd)

The available baud rates are:

300, 600, 1200, 2400, 4800, or 9600

Character Frame Format (ConF)

The character frame can be 7O1, 7E1, 7n2, or 8n1..

Controller Address Number (Addr)

Multiple controllers connected on the same RS485 interface line must each
have a different address number. A value of 0 does not require the address
specifier command, when communicating with the controller. The address
numbers range from 0 to 99.

Abbreviated or Full Transmission (Abrv)

When transmitting data, the controller can be programmed to suppress the
address number, mnemonics, units, and some spaces by selecting YES. An
example o f abbreviated and full transmission are shown below:

NO - 6 SET 123.8F<CR> <LF> Full Transmission
YES - 123.8<CR> <LF> Abbreviated Transmission

Remote Setpoint Parameters Module (7-n2 or 7-rS) (Optional)

Configuration of the Remote Setpoint involves scaling the input to the
desired setpoint range, selecting filter characteristics, and setting
remote/local setpoint transfer response.

Remote Setpoint Display Values (dSP1 and dSP2)

Key-in the display value for Scaling Point 1 and Scaling Point 2.

dSP1 -999 to 9999 (Ex. 0)
dSP2 -999 to 9999 (Ex. 500)

Remote Setpoint Signal Input Values (INP1 and INP2)

The signal input value can either be keyed-in via the front panel buttons or
an input signal can be applied to the appropriate signal input terminals.
Initially, the unit is in the key-in method.

Key-in Method

Key-in the display value for Scaling Point 1 and Scaling Point 2.

INP1 0.00 to 20.00 (Ex. 4.00 mA DC)
INP2 0.00 to 20.00 (Ex. 20.00 mA DC)

Signal Input Method

To change to the apply signal input method, press the D button while InP1
or InP2 is displayed. Front panel annunciators %P and DV flash and the
display indicates the signal value applied to the input terminals. The
controller can be toggled to the key-in method by pressing the D button again.
In this case, the previously accepted value is recalled.

When the desired value is indicated on the display, press the P button to
store the value and advance to the next parameter.

Remote Setpoint Filtering (Fltr and bANd)

The remote setpoint signals can be filtered with a time constraint from 1 to
25 seconds; or the filter can be disabled. The filter is an adaptive, first-order,
low p ass type. As long as the difference between the current reading and the
previous reading is less than the filter band value (band), the filter remains in
effect. When the difference exceeds the filter band, the filter disengages until
the difference is less than the filter band value. This action allows quick filter
response to large setpoint changes, while retaining filtering action under
normal process conditions.

Normally the filter band value is set slightly larger than the noise level of
the remote input. The time constant of the filter is set consistent with the
amount of filtering desired. Increased filter time constant values are effective
for smoothing remote setpoint readings. This may be beneficial for cascade
operation and other “live” signal applications.

Alternatively, the remote setpoint can be ramped at a controlled velocity to
limit controller response to large setpoint changes.

Remote/Local Setpoint Transfer Options (trnF)

When switching between Local or Remote Setpoint, the response of the
controller can be programmed in a variety of ways.

These responses apply to changes in setpoint mode from the controller’s
front panel and User Input. The table summarizes the responses for Setpoint
transfer operations:

SPtr Parameter Local to Remote Remote to Local

nor – Output may bump. Output may bump

Auto – No output bump. Process

integral action

trAC – Output may bump. Local setpoint assumes

Note: In situations where an output bump may occur,the setpoint ramp function

(SPrP) can be used to reduce or eliminate bumping when switching between

setpoints.

Second Linear DC Analog Output Module (8-A2) (Optional)

The Second Linear DC Analog Output provides retransmission of the

conditioned and scaled input signal independent of the Main Linear DC Output.

Second Linear DC Output Range (A2tP)

Select the type of output range:

0-10 = 0 to 10 V
0-20 = 0 to 20 mA
0-40 = 4 to 20 mA

The linear DC output range jumper must be set to match the range selected.
See Linear DC Output Jumper Selection, page 11. The linear DC output can
be re-calibrated to provide up to 5% of over range operation. See Linear DC
Output Calibration, page 69, for more details.

Second Linear DC Output Scaling Points (A2LO, A2Hl)

The output can be scaled based on the controller’s input display by use of
low and high scaling parameters. Reverse acting output is possible by
reversing the scaling points.

Factory Service Operations Module (9-FS)

The Factory Service Operations include: controller calibration, and reset
programming to factory configuration setting. Access to each operation is
protected by an access code number. Entering code 66 restores all parameters
to factory settings, the unit indicates the operation after the P button is
pressed, by displaying “rSEt” in the lower display momentarily.

Caution: Entering code 77,twice in succession, erases the controller calibration

values and defaults the values to nominal settings. Reading errors of

may result. Do not perform this operation unless the controller has lost

calibration. Loss of calibration is signaled by an “E-CL” error flag at

power-up. To clear this flag, perform calibration procedure as noted in

Factory Service Operations - Calibration (9-FS), page 68. Alternatively,

“stepping” through one of the calibration procedures clears the error flag,

but does NOT validate the calibration accuracy in any manner.

MANUAL CONTROL

The controller can be transferred between Automatic Control (closed loop;
On/Off or PID control) and Manual Control (open loop; where the control
does not work from the setpoint or process feedback.)

Manual operation provides percentage of control of the main output (per
the direct or reverse action configured in Output Parameter 2-OP OPAC)
from 0 to +100% power. When A2 is configured for cooling (O2), Manual
operation still provides 0 to 100% power to the main (O1) output and provides
percentage of control to cooling (O2) output from -100% to 0% power.
(Negative percent power is positive cooling (O2) percent power.)

To allow front panel switching between control modes, the Transfer
Parameter (trnF) must be enabled (Enbl) in Lockout Module (3-LC). The user
can then select Manual Control from the Hidden Function Mode using
Transfer Parameter (trnF). The percen t output power is then adjusted with the
Up and Down arrow buttons in the Normal Display Mode with the %P and
MN annunciators illuminated.

In Time Proportional output control (relay, or logic) the percent output
power is converted into output on time using Time Proportioning Cycle Time
(CYCt) value in Output Parameter Module (2-OP). For example with 4 cycle
time and 75% power, the output will be on (4 x.75) for 3 seconds and off for 1
second.

In Linear DC output control (0-10 VDC or 0/4-20 mA), the percent output
power is converted into a linear value per the Linear output low scaling value
(AnLO) and Linear output high scaling value (AnHI) in Output Parameter
Module (2-OP). For example with 0 VDC (scaled 0.0%) to 10 VDC (scaled
100%) and 75% power, the linear DC output will be 7.5 VDC.

When transferring the controller mode from or to Automatic Control, the
controlling outputs remain constant, exercising true “bumpless” transfer.
When transferring from Manual to Automatic, the power initially remains
steady but integral actions corrects (if necessary) the closed loop power
demand at a rate proportional to the Integral Time. The low (OPLO) and high
(OPHI) output power limits in Output Parameter (2-OP) are ignored when the
controller is in Manual Control.

-46-

ON/OFF CONTROL

Single Output

The controller operates in
ON/OFF Control when the
Proportional Band is set to 0.0%. In
this control, the process will
constantly oscillate about the
setpoint value. The amount of
ON/OFF Control Hysteresis
(CHYS) in Output Parameter
Module (2-OP), together with the
process characteristics determines
the period and amplitude of the
oscillations. Larger values of
hysteresis increase both the
amplitude and period of
oscillations but also reduce the
number of output switching cycles.

The Control Action (OPAC) in
Output Parameter Module (2-OP)
can be set to reverse (rEv) for
heating (output on when below the
setpoint) or direct (drct) for cooling
(output on when above the setpoint)
applications.

In controllers with operating
system software revision earlier
than V4.x, the ON/OFF Control
Hysteresis value is not balanced
around the setpoint value. In these
controllers, the Hysteresis is totally
added to the setpoint in reverse
action and totally subtracted from
the setpoint in direct action. The
revision number of the controller’s
operating system software is shown
in the secondary (bottom) display
during controller power up.

Software Revision V4.0 or Later

-47-

Figure 22, Output 1 (O1) ON/OFF Control

Software Revision V3.x or Earlier

Dual Output

For heat and cool systems, the heat (O1) and cool (O2) outputs can be used
together in the ON/OFF control. For this operation, set the Cooling Relative
Gain (GAN2) in Cooling ParameterModule (5-02) to 0.0. This places O2 into
ON/OFF Control. In this mode, the ON/OFF Control Hysteresis (CHYS) in
Output Parameter Module (2-OP) applies to both O1 and O2. The Heat/Cool
Deadband (db-2) in Cooling Parameter Module (5-02) sets the amount of
operational deadband or overlap between the outputs.

For these applications, the Control Action (OPAC) in Output Parameter
Module (2-OP) is normally set to reverse (rEv). This sets O1 into reverse
(heat) with O2 always in direct (cool). Cooling output for the CN63300 is
referred to as the second control output.

In controllers with operating system software revision lower than 4.0, the
ON/OFF Control Hysteresis value is not balanced. In these controllers, the
Hysteresis is totally added or subtracted from the setpoint. The revision
number of the controller’s operating system software is shown in the
secondary (bottom) display during controller power up.

AUTO-TUNE FOR PID CONTROL

Auto-Tune is a user initiated function in which the controller automatically
determines the PID settings based upon the process characteristics. During
Auto-Tune, the controller temporarily causes the system to oscillate by
cycling the output power from 0 to 100%. The nature of these oscillations
determines the settings of the controller’s parameters.

Auto-Tune Code. A code setting of zero gives the fastest response with
possible overshoot, and a code of two gives the slowest response with
minimum overshoot.

Figure 27, Auto-Tune Code

Note: If the induced oscillations caused by Auto-Tune can cause system

problems or are otherwise unacceptable, the Manual Tuning Procedure can

be used as a tuning alternative.

Prior to initiating Auto-Tune, it is essential that the controller be
configured to the application. In particular, Control Hysteresis (CHYS) and
Auto-Tune code (tcod) must be set in the Output Parameters section.
Auto-Tune requires the hysteresis setting to be above the process noise floor;
generally, 2 - 5 degrees or 1-2% of range is adequate. For most applications,
the control hysteresis should be set at 2 (factory setting). The Auto-Tune code
may be set to yield the response characteristics shown in Figure 27,

Figure 28, Auto-Tune Operation

The following controller parameters are automatically adjusted by

Auto-Tune according to the characteristics of the process:

Proportional Band (ProP)
Integral Time (Intt)
Derivative Time (dErt)
Input Filter (Fltr)
Output Power Dampening (OPdP)

As shown in Auto-Tune Operation, Figure 28, Auto-Tune Operation cycles
the process at a control point 3/4 of the distance between the current process
value (at the instant Auto-Tune is started) and the setpoint. The 3/4 control

-50-

point was selected to reduce the chance of overshoot at setpoint when
Auto-Tuning at start-up. If Auto-Tuning from setpoint and overshoot is
unacceptable, temporarily lower the setpoint by an amount of the oscillation
and then Auto-Tune. Reset the setpoint to the original value when Auto-Tune is
complete. After starting Auto-Tune, the secondary display indicates the
current phase (Aut1, Aut2, Aut3, & Aut4). If the controller remains in an
Auto-Tune phase unusually long, the process or connections may be faulty.
Additionally, during Auto-Tune it is important that disturbances to the system
be minimized, as these may have an effect on the parameter determination.

Initiate Auto-Tune

Auto-Tune may be initiated at start-up, from setpoint, or at any other

process point.

To Initiate Auto-Tune:

1. Make sure that Auto-Tuning is enabled in Lockouts Parameter Module
(3-LC).

2. Place the controller into the Normal Display Mode.

3. Press P for 3 seconds from Normal Display Mode.

4. Scroll to “tUNE” b y use of P, if necessary.

5. Select “YES” and press P.

Auto-Tune is initiated.

To Cancel Auto-Tune: (Old PID settings remain in effect).
A) Make sure that Auto-Tuning is enabled in parameter lockouts module.

1. Place the controller into the normal display mode.

2. Press P for 3 seconds from normal display mode.

3. Scroll to “tUNE” b y use of P, if necessary.

4. Select “NO” and p ress P.

5. Auto-Tune canceled.

B) Or reset the controller by disconnecting power.

Auto-Tune Of Heat/Cool Systems

During Auto-Tune of heat/cool systems, the controller switches the
cooling output (O2) on and off in addition to the heat output (O1). The
heat/cool overlap deadband parameter (db-2) determines the amount of
overlap or deadband between the two outputs during Auto-Tune. For most
applications, set this parameter to 0.0 prior to starting Auto-Tune. After the
completion of Auto-Tune, this parameter may need to be reset.

It is important that external load disturbances be minimized, and if present,
other zone controllers idled as these may have an effect on the PID constant
determination. The controller additionally sets the Cooling Relative Gain
parameter (GAN2) for heat/cool systems.

Some water cooled processes exhibit an extreme non-linear gain
characteristic. That is, the process cooling gain starts very high and flattens out
deeper into the cooling region. This ef fect may result in regular oscillations at
setpoint as the controller applies heat to counteract the effect. These processes
may benefit from a lower cooling fan setting and/or reduced water flow in the
jacket or manifold. The process heat and cool gains should be balanced as much
as possible, and the controller gains adjusted to the process.

Auto-Tune Of Cascade Control

The following procedure may be used to tune cascaded controllers:

1. Place the Secondary controller into Local Setpoint mode and Manual

(USEr) mode of operation

2. Adjust output power level of the secondary until primary variable is close

to primary setpoint (5% of range).

3. Key-in secondary setpoint value equal to secondary process value.

4. Auto-Tune the secondary controller while in Local Setpoint mode.

5. Place the secondary controller into Remote Setpoint mode and Automatic

(Auto) mode of operation.

6. Auto-Tune the primary controller while the primary is in Automatic mode

of operation.

7. Initial tuning of system is complete.

After the process has stabilized, the primary and secondary may be

re-tuned in Automatic mode of operation. Normally, the primary requires

re-tuning whenever the secondary PID constants are changed.

Note: For Remote Setpoint controllers, the Auto-Tune control point is derived

from the Remote Setpoint when in Remote Setpoint mode and from the Local

Setpoint when in Local Setpoint mode.

PID CONTROL EXPLANATIONS

Proportional Band

Proportional band is defined as the “band” (range) the process changes to
cause the percent output power to change from 0% to 100%. The band may or
may not be centered about the setpoint value depending upon the steady state
requirements of the process. The band is shifted by manual offset or integral
action (automatic reset) to maintain zero error. Proportional band is
expressed as percent of input sensor range.

For CN63100, the ranges are fixed for the thermocouple and RTD types.

For CN63300, the range is set by the difference between “dSP2 and dSP1”.

Figure 29, Proportional Band

Example: Thermocouple type T with a temperature range of 600°C is used

and is indicated in degrees Celsius with a proportional band of 5%. This

yields a band of 600°C X 5% = 30°C.

The proportional band should be set to obtain the best response to a
disturbance while minimizing overshoot. Low proportional band settings (high
gain) result in quick controller response at expense of stability and increased
overshoot. Settings that are excessively low produce continuous oscillations at
setpoint. High proportional band settings (low gain) result in a sluggish
response with long periods of process “droop”. A proportional band of 0.0%
forces the controller into ON/OFF control mode with its characteristic cycling
at setpoint (See ON/OFF Control, page 47, for more information).

Integral Time

Integral time is defined as the time, in seconds, in which the output due to
integral action alone equals the output due to proportional action with a
constant process error. As long as a constant error exists, integral action
repeats the proportional action each integral time. Integral action shifts the
center point position of the proportional band to eliminate error in the steady
state. The units of integral time are seconds per repeat.

Integral action (also known as “automatic reset”) changes the output power
to bring the process to setpoint. Integral times that are too fast (small times) do
not allow the process to respond to the new output value. This causes
over-compensation and leads to an unstable process with excessive overshoot.
Integral times that are too slow (large times) cause a slow response to steady
state errors. Integral action may be disabled by setting the time to zero. If time is
set to zero, the previous integral output power value is maintained.

If integral action is disabled, manual reset is available by modifying the
output power offset (“OPOF” initially set to zero) to eliminate steady state
errors. This parameter appears in unprotected parameter mode when integral
time is set to zero. The controller has the feature to prevent integral action
when operating outside the proportional band. This prevents “reset
wind-up”.

Figure 30, Integral Time

-52-

Derivative Time

Derivative time is defined as the time, in seconds, in which the output due
to proportional action alone equals the output due to derivative action with a
ramping process error. As long as a ramping error exists, the derivative action
is “repeated” by proportional action every derivative time. The units of
derivative time are seconds per repeat.

Derivative action is used to shorten the process response time and helps to
stabilize the process by providing an output based on the rate of change of the
process. In effect, derivative action anticipates where the process is headed
and changes the output before it actually “arrives”. Increasing the derivative
time helps to stabilize the response, but too much derivative time coupled
with noisy signal processes, may cause the output to fluctuate too greatly,
yielding poor control. None or too little derivative action usually results in
decreased stability with higher overshoots. No derivative action usually
requires a wider proportional and slower integral times to maintain the same
degree of stability as with derivative action. Derivative action is disabled by
setting the time to zero.

Output Power Offset (Manual Reset)

If the integral time is set to zero (automatic reset is off), it may be necessary
to modify the output power to eliminate errors in the steady state. The output
power offset (OPOF) is used to shift the proportional band to compensate for
errors in the steady state. The output power offset (OPOF) parameter appears
in the unprotected mode, if the integral time equals zero. If integral action
(automatic reset) is later invoked, the controller continues from the previous
output power offset and updates accordingly.

PID Adjustments

To aid in the adjustment of the PID parameters for improvedprocess control,
a chart recorder is necessary to provide a visual means of analyzing the process.
Compare the actual process response to the PID response figures with a step
change to the process. Make changes to the PID p arameters in no more than
20% increments from the starting value and allow the process sufficient time to
stabilize before evaluating the ef fects of the new parameter settings.

MANUAL TUNING FOR PID CONTROL

In some unusual cases, the Auto-Tune function may not yield acceptable
control results. In this case, the controller can be manually tuned to optimize
the PID setting according to the process and the desired control requirements.

Manual Tuning Procedure

A chart recorder or data logging device is necessary to measure the time
between process cycles.

1. Set the Proportional Band (ProP) from the Unprotected Parameter Mode to

10.0% for CN63100 models and 100.0% for CN63300 models.

2. Set the Integral Time (Intt) and Derivative Time (dErt) to 0 seconds.

3. Set Output Power Dampening Time (OPdP) in Output Parameter Module

(2-OP) to 0 seconds.

4. Set Output Cycle Time (CYCt) in Output Parameter Module (2-OP) to no

higher than 1/10 of the process time constant (when applicable).

5. Place controller in Manual Control and set % Power f rom the Normal

Display Mode to drive the process value to the desired value. Make certain

that the controller can drive the process to the setpoint. Allow the process

to stabilize after setting the % Power.

6. Place controller into Automatic Control. If the process will not stabilize and

starts to oscillate, set the Proportional Band 2x higher and go back to step 5.

7. If the process is stable, decrease Proportional Band setting by 2x and

change the setpoint value a small amount to excite the process. Continue

with this step until the process oscillates in a continuous nature.

8. Fix the Proportional Band to 3x the setting that justcaused the oscillations.

9. Set the Integral Time to 2x the period of the oscillations.

10. Set the Derivative Time to 1/8 (0.125) the Integral Time.

11. Set Output Power Dampening Time to 1/40 (0.025) the period of the

oscillation.

Note: This procedure is an alternate to the controller’s Auto-tune function. It

will not provide acceptable results if system problems exist.

-55-

REMOTE SETPOINT OPTION

A remote 0/4 to 20 mA analog input signal can be used to change the
setpoint value. This input can be scaled over a process range independent of
that of the system range. In operation, the front panel “MN” indicator
illuminates for local setpoint operation and is off for remote setpoint
operation. In either mode, the indicator flashes during Manual Mode.
Filtering, ramp rate (velocity limiting), and local/remote transfer response
options can be configured to suit the application. Local/Remote transfer
operations are performed either externally (user input) or at the keypad.

If large changes in the remote setpoint signal result in undesirable
controller performance, the remote setpoint can be velocity limited (ramped)
by the setpoint ramp parameter (SPrP).

Similarly, if fluctuation in the remote setpoint signal also results in poor
performance, the programmable filter can be used to provide a steady setpoint
to the controller. A unique feature of the filter is the filter band. Fluctuations
that occur that are less than the filter band value keep the filter engaged, while
fluctuations outside the filter band d isable the f ilter. This action allows the
controller to respond rapidly to large changes of the remote setpoint signal.

CASCADE CONTROL

External cascade control involves the use of two controllers, one of which

has a Remote Setpoint Input.

The outer loop controller (Primary controller) directs the setpoint of the
inner loop controller (secondary controller) through the linear DC output.
The secondary controller has a Remote Setpoint option in order to receive the
directed setpoint. See Figure 34, Cascade Control, for more details.

Note: The Remote Setpoint of the secondary controller must be scaled prior to

tuning the controllers. Normally, the Remote Setpoint is scaled to equal the

actual process range of the secondary. Scaled in this way, the primary

controller can direct the setpoint of the secondary controller over its

operating range. Normally, the secondary controller is a faster control loop.

It is able to respond quickly to disturbances before they affect the primary

loop. Therefore, thecontrol quality of the primaryloop under cascade control

is superior to that of a single loop controller.

Figure 34, Cascade Control

SERIAL COMMUNICATIONS INTERFACE

RS-485 Serial Communications

The optional RS-485 serial communication interface provides two-way
communication between the controller and other compatible equipment such
as a printer, PLC, HMI, or a host computer. In multipoint applications, each
controller can be configured with a unique node address ranging from 0-99.
Through this serial interface, data from the controller can be interrogated or
changed, alarm output(s) reset and Auto-tune invoked.

Since the same pair of wires are used for both transmit and receive, only
one-way communication is possible at a time. The controller has a variable
response time, to allow the host device adequate time to release the
communication line after issuing a command to the controller.

Controller Configuration

The controller’s serial communication format is configured in Serial
Communication Program Module 6-SC using the front panel. Baud rate and
character frame must be matched to the other communicating device. The node
address parameter is a unique address number assigned to each slave unit on the
bus.

Sending Commands And Data

When sending commands to the controller, a command string of ASCII
characters must be constructed. The string varies in length depending on the
nature of the command. At most, a command string consists of a Controller
(Node) Address number (not required for address of 0), a Command Code
character, a Register Identification character (for most commands),
Numerical Data (if writing data to the controller) and ending with a string
Terminator of “*” or “$”. The controller will not respond with an error
message to invalid commands.

Sending Numeric Data

Data written to individual registers must be limited to the registers
numerical data range (See Register Identification Table). If more digits are
sent, the controller only accepts the last four digits of the numeric data.
Negative numbers must have a minus sign. The controller ignores any
decimal point and conforms the number to the register identification
resolution. (Example: “25” is written to the proportional band register. The
value recorded by the register is now 2.5. If a value of 25% is intended, write a
value of 25.0 or 250.

Command Code Explanations

Controller (Node) Address: N

When more than one controller is on the serial communication bus, a

unique controller (node) address must be assigned to each unit. The address
range extends from 0 to 99. This is defined in the controller configurations.
To communicate with a specific controller, the address code N followed by
the controller’s address value must start a command string. A controller with
an address of 0 does not require the node address command. Controllers with
an address greater than 0 will respond to transmit commands by sending their
address followed by the requested data.

Read Register Command Code: T

The Read Register command is used to read data from a register. This
command must be followed by a Register ID character. In full response mode,
the controller responds to this command by transmitting its Address (if
greater than 0), corresponding register mnemonic and register data. In
abbreviated response mode, the controller transmits data only. The response
time to this command is controlled by the type of termination character. This
is a single register response.

Write Register Command Code: V

The Write Register command is used to write data to a register. This
command must be fo llowed by a Register ID character and Numeric Data. A
unique command line is required for each register write operation. No
response occurs for invalid write operations. The Read Register command
(T) can be used fo r readback verification.

Reset Alarm Command Code: R

The Reset Alarm command resets the alarm outputs. This command must
be followed by a Register ID character (G for Alarm 1, and H for Alarm 2).
This command does not alter the actual alarm mode or value setting.

Control Action Command Code: C

The Control Action command is used to aff ect certain controller operating
modes.The registers used with this command are: Auto/Manual mode select,
Auto-Tune mode select, and Remote Setpoint mode select. After the Register
ID character, either a “1” or “2” is sent to set a specific controller mode.

Block Read Register Command Code: P

The Block Read Register command is used to read data from multiple
registers with a single command. With this command, if no register ID
characters follow, the controller responds with register data that is preset by
the Print Options parameter (Module 6-SC). This mode is useful for print
ticket applications. However, if Register ID characters follow this command,
the controller responds with register data indicated by the ID character field.
This character ID field does not follow the normal Register ID format, but
instead is a field composed of ASCII encoded bit mapped bytes. (See Block
Read Command Register ID Table.)

Four of these field bytes are used in this format:

P<Byte1><Byte2><Byte3><Byte4>

Each byte represents a code that selects a register(s) for transmission. The
Block Read Command Byte Table relates specific registers for reads to the
field bytes.

Examples:

Print:Alarm1andAlarm2values(bothareinByte2table)

Explanation: Byte1 = 0, Byte2 = 3, Byte3 & Byte4 are not needed

ASCII String : P03* (Either the “*” or “$” terminator could be used.)

For those programming in HEX: P = <50>, 0 = <30>, * = <2A>, $ = <24>

HEX String : <50><30><33><2A>

Print: Input, Cooling Deadband and Output Status (Input is in Byte1 table

and the other two are in Byte4 table)
Explanation: Byte1 = 8, Byte2 = 0, Byte3 = 0, Byte4 = C
ASCII String : P800C$ (Either the “*” or“$” terminator could be used.)
HEX String : <50><38><30><30><43><24>

Terminator:*or$

After a Read Register command is sent, the response time of the controller

is determined by the type of command terminator character. The “$”
terminator causes a response time of 2 msec to 100 msec and the “*”
terminator causes a response time of 100 msec to 200 msec. (The 2 msec delay
allows for a two character transmission time at 9600 baud. ) The controller
does not begin processing the command string until the “$” or “*” is received.
The Carriage Return <CR> and the Line Feed <LF> cause the controller to
ignore the command string. When writing setpoint values, only values using
the “*” terminator are saved to E

Unique Register Explanations

Setpoint Ramp Using Automatic Setpoint Ramping Register: K

The controller’s Setpoint Ramp parameter provides a controlled ramp when
the setpoint value is changed. (The Setpoint Ramp value can be changed by
using VK command.) When the setpoint value is changed, the controller begins
to ramp from the existing value to the new target setpoint, at a rate set by this
register. A value of zero in the Setpoint Ramp register disables ramping.

During the controlled ramp phase, the Integral Action is automatically
disabled. This tends to reduce overshoot due to excessive integral build-up. The
Integral Action automatically resumes at the end of the controlled ramp phase.

To terminate a ramp in progress, write 0 (zero) to the Setpoint Ramp
register. This results in immediate control to the target setpoint.

Setpoint Ramp Using Periodic Setpoint Write Register: B

A host computer can command the setpoint value of the controller by
writing new setpoint values based on clock ticks. In this manner, the host has
explicit control over setpoint values, ramp and hold phases.

During ramp phases, the Integral Action may lead to overshoot problems.
In this case, the integral action may be slowed or completely disabled by
setting the integral time register.

Periodic Setpoint Write Commands (E

In the case of periodically writing setpoint values to the controller (host is
running a temperature/process profile), terminate the write command with
the “$” terminator character. This instructs the controller to accept the
setpoint value, but not to write the value to E
cycling of the internal memory chip, which has a finite life-cycle rating (1
million typical). This rating should not be exceeded.

After power loss, the setpoint value written will be lost when using “$”.
Termination of the setpoint write command with the “*” character instructs
the controller to save the value to E

Output Status: W

The Output Status register indicates the present status of the controller’s
discrete alarm outputs (coils). This is a read only register. The controller
responds with OST followed by a field consisting of 4 bytes. The bytes
represent the status of the outputs in the following order: main output O1,
cooling/ secondary output (O2), alarm 2 output (A2), alarm 1 output (A1).
When the output is on, the corresponding byte is “1.” When the output is off,
the corresponding byte is “0”.

Communication Format

Data is transferred from the controller over a serial communication
channel. In serial communications, the voltage is switched between a high
and low level at a predetermined rate (baud rate) using ASCII encoding. The
receiving device reads the voltage levels at the same intervals and then
converts the number back to a character.

The table lists the required voltage levels at the receiver for RS485
interface.

Logic RS485 Interface State

1 a-b <-200 mV mark (idle)

0 a-b >+200 mV space (active)

Data is transmitted one byte at a time. Each ASCII character is “f ramed”
with a beginning start bit, an optional error detection parity bit and one or
more ending stop bits.

-61-

Figure 36, Character Frame

To allow the host adequate time to release the bus after a transmission, the
response time of the controller is programmable. The controller utilizes a
receiver design that interprets a mark condition for open connections.

Start Bit and Data Bits

Data transmission always begins with the start bit. The start bit signals the
receiving device to prepare for reception of data. One bit period later, the
least significant bit of the ASCII encoded character is transmitted, followed
by the remaining data bits. The receiving device then reads each bit position
as it is transmitted. Since the sending and receiving devices operate at the
same transmission speed (baud rate), the data is read without timing errors.

Parity Bit

After the data bits, the parity bit is sent. The transmitter sets the parity bit to
a zero or a one, so that the total number of ones contained in the transmission
(including the parity bit itself) is either even or odd. This bit is u sed by the
receiver to detect one bit errors occurring in the transmission. Given this
limitation, the parity bit is often ignored by the receiving device. The
controller ignores the parity bit of incoming data and sets the parity bit to odd,
even or none (mark parity) for outgoing data.

Stop Bit

The last character transmitted is the stop bit. The stop bit provides a single
bit period pause to allow the receiver to prepare to re-synchronize to the start
of new transmission (start bit of next byte). After the stop bit, the receiver
continuously looks for the occurrence of the next start bit.

Command Response Time

The controller can only receive or transmit data at any one time (half-duplex
operation). If bus activity, such as another command, occurs before the
controller has ended its transmission, garbled data will result. When sending
commands and data to the controller, timing restrictions are imposed when
sending another command afterwards. This allows enough time for the
controller to process the command and prepare for the next command. If the
timing requirements are not obeyed, lost transmissions may result.

Troubleshooting Serial Communications

If problems are encountered when interfacing the controller(s) and host

device or printer, the following check list can be used to help find a solution.

1. Check all wiring. Proper polarity of all devices on the serial loop must be
observed. Refer to previous application examples.

2. Check the controller’s communication format in module 6-SC. Make sure
all devices on the serial loop are configured with the same
communication format.

3. Check the requesting device constructed command string format.

4. When sending commands to the controller, an asterisk “*” or dollar sign
“$” must terminate the command. Make sure a carriage return or line feed
does not follow the command terminator.

5. Check the controller’s unit address in module 6-SC. It should be zero if the
address command is not used in the command string for single controller
configurations. In multiple controller configurations, make sure each
controller has a unique unit address.

6. Initiate transmissions from the controller by programming the User Input
for PrNt in module 1-IN for print and programming module 6-SC at PoPt
set INP (input) to YES. As long as the user input is connected to common,
controller data will be sent.

7. With two-way communications or multiple controller configurations,
make sure only one device is communicating at a time.

8. If all of the above has been done, try reversing the polarity of the serial
wires at host device or printer. Some devices have reversed polarity.

APPLICATION EXAMPLES

CN63100 OEM Paint Sprayer Application

An OEM manufacturing spray painting equipment utilizes the CN63100 to
maintain optimum paint temperature. In addition to the low cost, the 1/16 DIN
package size permits the OEM to design temperature control into various
sized painting equipment, from small hand sprayers to large paint booths. The
heating element used to heat the paint, is connected to the Main Control
Output (OP1) programmed for On/Off control. Alarm 1 is programmed as
Band Inside Acting, so that as long as the paint temperature is within
manufacturer’s specifications for temperature, the “GO” light is on. Alarm 2
is programmed as Band Outside acting so that the “NO GO” light is lit when
the paint temperature is more than 12°outside the manufacturer’s
specifications of 140 to 150°F.

CN63300 Water Processing Application

A city water company needs to maintain a steady flow of water for their
customer needs. They have an existing 0 to 10 VDC flow transmitter to
measure the water flow. They need to control the water flow, have a high and
low alarm, and keep a recorded chart of the flow for later reference. The Main
Linear DC output of the CN63300 is used to control the position of water
value to maintain the desired flow setpoint value. The CN63300 relay outputs
are programmed to give a high flow alarm and a low flow alarm. With the
Second Linear DC output model, the f low measurement to the CN63300 can
be retransmitted to a chart recorder.

CHECKS AND CALIBRATION

The instrument has been fully calibrated at the factory for all input types. If
the unit appears to be indicating or controlling incorrectly, see
Troubleshooting, page 71, before attempting this procedure.

If the controller is suspected of reading incorrectly, the instrument may be
checked for indication accuracy without disturbing the factory calibration.
The following procedures may be used for this purpose.

Note: Allow 1/2 hour warm-up before checking these parameters.

MAIN INPUT CHECK

mV Reading Check (CN63100)

1. Connect a DC mV source with an accuracy of 0.03% or better to terminal #8

(-) & #9 (+).

2. Configure Input Parameters Module 1 for linear mV (lin) input, under

tYPE.

3. Compare the controller read-out to the standard at various points over the

range (-5.00 mV to 56.00 mV). The tolerance is ±(0.15% of reading +1

LSD).

4. Calibrate the controller if the readings are out of tolerance.

Thermocouple Cold Junction Temperature Check (CN63100)

1. Connect a thermocouple probe of known accuracy (Types T, E, J, K, N

only) to controller. Select the probe used in Configure Module 1.

2. Connect a reference temperature probe to measuring end of thermocouple

to monitor temperature. Allow sufficient time for temperatures to equalize.

3. Compare controller display with reference temperature probe. The

controller display should equal the calibrated probe temperature.

(Tolerance is ±1°C).

4. Calibrate the cold junction temperature if out of tolerance.

RTD Ohms Reading Check (CN63100)

1. Connect RTD simulator (with an accuracy of 0.1 ohm or better) capable of

operating with less than 150 μA to terminals #8, #9, & #10.

2. Configure Input Parameters Module 1 for linear ohms (rLIn) input, under

tYPE.

3. Compare the controller read-out with the RTD simulator at various points

over the range 1.0 to 300.0 ohms. The tolerance is ±(0.3% of span ±1LSD).

4. Calibrate the controller RTD ohms if out of tolerance.

Voltage Check (CN63300)

1. Connect a DC voltage source with an accuracy of 0.1% or better. Apply a 0
to 10 V signal to terminals #8 (-) & #9 (+).

2. In Input Module 1, configure input signal InP1 and display value dSP1 to

0.00. Configure input signal InP2 and display value dSP2 to 10.00.

3. Compare the controller readout to the voltage source over the range (0-10 V).
The tolerance is ±(0.3% of reading +0.03 V).

4. Calibrate the controller if the readings are out of tolerance.

Current Check (CN63300)

1. Connect a DC current source with an accuracy of 0.1% or better. Apply a 0
to 20 mA signal to terminals #8 (-) & #10 (+).

2. In Input Module 1, configure input signal InP1 and display value dSP1 to

0.00. Configure input signal InP2 and display value dSP2 to 20.00.

3. Compare the controller readout to the current source over the range (0-20
mA). The tolerance is ±(0.3% of reading +0.04 mA).

4. Calibrate the controller if the readings are out of tolerance.

Remote Setpoint Input Check (CN63100 and CN63300)

1. Connect a DC current source with an accuracy of 0.03% or better. Apply a 0
to 20 mA sig nal to terminals 13 (+) and 14 (-).

2. In Remote Setpoint Input Module 7, configure input signal InP1 and
display value dSP1 to 0.00. Configure input signal InP2 and display value
dSP2 to 20.00.

3. Compare the readout in the secondary main display to the current source
over the range (0-20 mA). The tolerance is ±(0.2% of full scale +½ LSD).

4. Calibrate Remote Setpoint Input if readings are out of tolerance.

Error Flag E-CL

If error flag “E-CL” appears at power-up, a loss of calibration parameters

due to noise spikes has occurred. Entering code 77 twice in Factory Service
Operations Module (9-FS) erases the controller calibration values and
defaults the values to nominal settings. Reading errors of ±10% may result. It
is recommended that the controller be fully re-calibrated. If using
thermocouple only, the RTD calibration need not be performed.

-67-

Note: The “E-CL” flag may be cleared by “stepping” through cold junction or

linear output calibration procedures without the need to change any
calibration values. A

10% reading error will still exist.

Calibration For CN63100

When re-calibration is required (g enerally every two years), this procedure
should be performed by qualified technicians using appropriate equipment.
Equipment source accuracy of 0.03% or better is required.

The procedure consists of: applying accurate mV signals, setting the
thermocouple cold junction temperature, and applying precision resistance,
among others. Allow a 30 minute warm-up period before starting this procedure.
Do not use thermocouple wire for the Millivolt or RTD ohms Calibration.

This procedure may be aborted b y disconnecting power to the controller
before exiting the configuration mode. The existing calibration settings
remain in affect.

Note: After completing any of the calibration sequences, the controller defaults

the input sensor type to thermocouple type “J” (tc-j). Be sure to set input

sensor for proper type.
Note: The controller must be restored to normal display mode before any data

is stored.

Thermocouple Cold Junction Calibration (CJC)

This procedure must be performed AFTER an accurate mV calibration.

1. Exit Factory Service Operations (press D) and return to Normal Display
Mode.

2. Connect a thermocouple probe of known accuracy to the controller (Types
T, E, J, K, and N only). Select the probe type used in Configure Module 1.

3. Connect a reference temperature probe to the measuring end of the
CN63100 thermocouple probe. The two probes should be shielded from air
movement and allowed sufficient time to equalize in temperature. (As an
alternative, the CN63100 thermocouple probe may be placed in a
calibration bath of known temperature.)

4. Compare controller display with reference temperature probe (or
calibration bath). If the displayed controller temperature does not equal the
reference probe temperature, calculate the CJ Error as follows:

CJ Error = reference probe temperature - displayed controller temperature

5. Enter Factory Service Operations Module (9-FS).
