The instrument is a microprocessor based circular chart Recording Profile Controller capable
of measuring, displaying, recording and controlling a variety of inputs. Applications include
temperature, level, pressure, flow and others. The instruments can be specified as either a
single or as a dual pen model. The second pen can be selected as a profile control or a
single setpoint control.
Recording, control functions, alarm settings, profile entry and other parameters are easily
entered via the keypad. All user data can be protected from unauthorized changes by the
Enable mode security system, and is protected against memory loss, as a result of AC power
outage, by battery back-up.
The process sensor input for each terminal block is user configurable to directly connect to
either thermocouple, RTD, mVDC, VDC, or mADC inputs. Changes in input type can easily be
made by the user. Thermocouple and RTD linearization, as well as thermocouple cold
junction compensation, are performed automatically. The instrument process variable inputs
are isolated. An isolated 24 VDC regulated transmitter power supply can be provided in the
instrument for use with up to two 4 to 20 mADC process sensor transducers.
The instrument can be ordered to operate on either 115 VAC or 230 VAC power at 50/60 Hz.
The 230 VAC option includes a switch for selecting either 230 VAC or 115 VAC operation.
The instrument is housed in a structural foam enclosure suitable for panel or surface
mounting.

1.1.2 RECORDING
The instrument records the selected process variable on a 10-inch circular chart. One box of
standard charts is provided with each recorder. Charts are available in a wide selection of
ranges. Chart rotation speed is programmable from 0.1 to 999.9 hours per revolution in 0.1
hour increments. The instrument can be ordered with one or two pens. Pen 1 is red and Pen 2
is green. Pens are the disposable fiber-tip type.
1.1.3 DISPLAYS
Each instrument is provided with a digital display and status indicator for each pen provided
(See Figure 1-1, page 5). The display may be configured to display the Process Value,
Process Value and Setpoint, Deviation from Setpoint only, Deviation and Setpoint, or Setpoint
only. During configuration the display(s) is/are used to show the enabled modes of operation
and the parameter codes.
The display in the upper right corner is for Pen 1, the display in the lower right corner is for
Pen 2 (if provided). The upper display includes status indicators for Manual mode operation,
Output 1, Output 2 , Alarm, Setpoint, negative value, degrees C, degrees F, engineering units,
Ramp, Soak and Six segment lamps. The lower display (if provided), includes status indicators for Manual mode operation, Output 1, Output 2, Alarm, Setpoint, negative value, degrees
C, degrees F, and engineering units. (Relative Humidity will be indicated in engineering
units). See Figure 1-2 ( page 7).
Display resolution is programmable for 0.1 or 1 degree for thermocouple and RTD inputs, and
none, one, two or three decimal places for other input types. Relative Humidity will be
indicated as whole number only.
1.1.4 CONTROL
The instrument can be provided with relay, solid state relay driver and milliamp DC outputs.
Instruments can be programmed for on-off, time proportioning, current proportioning or
position proportioning control depending upon the output(s) present. Relay(s) and Solid State
Relay Driver(s) may be assigned to be On or Off during the profile ramp and soak of a profile
segment. Switching between the Control mode and the Manual mode of operation is easily
accomplished with a dedicated key on the keypad. Switching is bumpless from the Control to
the Manual mode, and while in manual, manipulation of proportional outputs is possible. Each
pen of a dual pen recording controller is provided with its own AUTO/MANUAL key . Other
standard control features include proportional control output limits, setpoint limits, anti-reset
windup and a unique Automatic Transfer function. If configured, the Automatic Transfer
function allows manual control of the proportional output until the process reaches the setpoint
at which time the instrument will go into the Control (automatic) mode of operation.
1.1.5 ALARM
An Alarm indicator is standard for each pen. Two alarm functions are provided for each pen
and the alarm indicator will light if either alarm for that pen is On. Alarm settings are programmable. Alarm type may be selected as process direct or reverse (high or low), deviation from
setpoint direct or reverse, and deviation band open or closed within the band. Alarm outputs
can be provided by assigning any relay(s) Single Pole/Single Throw (SPST)or Solid State
Relay (SSR) driver to the respective alarm.
6
1.1.6 PROCESS VALUE RE-TRANSMISSION OUTPUT
If an instrument is specified with mADC current output(s), any of the outputs may be programmed to operate as a process value re-transmission output. The output is scaleable but
can not be used as a control output while assigned as a process value re-transmission output.
1.1.7 DIGITAL COMMUNICATIONS
The instrument can be ordered with a Digital Communications option that provides the
capability of bi-directional communications with a supervisory computer. A dual pen
instrument can have an individual address selected for each pen. Refer to the Communications Protocol Manual (Form 2878) for more details regarding the communications option.

Preparations for Wiring 2.5
2.5.1 WIRING GUIDELINES
Electrical noise is a phenomenon typical of industrial environments. The following are guidelines that must be followed to minimize the effect of noise upon any instrumentation.
2.5.1.1 INSTALLATION CONSIDERATIONS
Listed below are some of the common sources of electrical noise in the industrial environment:
• Ignition Transformers
• Arc Welders
• Mechanical contact relay(s)
• Solenoids
Before using any instrument near the devices listed, the instructions below should be
followed:
1. If the instrument is to be mounted in the same panel as any of the listed devices,
separate them by the largest distance possible. For maximum electrical noise
reduction, the noise generating devices should be mounted in a separate
enclosure.
2. If possible, eliminate mechanical contact relay(s) and replace with solid state
relays. If a mechanical relay being powered by an instrument output device
cannot be replaced, a solid state relay can be interposed to isolate the instrument.
(Continued on next page)
9
3. A separate isolation transformer to feed only instrumentation should be
considered. The transformer can isolate the instrument from noise found on the
AC power input.
4. If the instrument is being installed on existing equipment, the wiring in the area
should be checked to insure that good wiring practices have been followed.
2.5.1.2 AC POWER WIRING
Earth Ground
The instrument includes noise suppression components that require an earth ground
connection to function. To verify that a good earth ground is being attached, make a resistance check from the instrument chassis to the nearest metal water pipe or proven earth
ground. This reading should not exceed 100 ohms. Each instrument should have a dedicated
earth ground. Do not chain link multiple instrument ground wires.
Neutral (For 115VAC)
It is good practice to assure that the AC neutral is at or near ground potential. To verify this, a
voltmeter check between neutral and ground should be done. On the AC range, the reading
should not be more than 50 millivolts. If it is greater than this amount, the secondary of this
AC transformer supplying the instrument should be checked by an electrician. A proper
neutral will help ensure maximum performance from the instrument.
2.5.1.3 WIRE ISOLATION/SEGRATION
The instrument is designed to promote proper separation of the wiring groups that connect to
the instrument. The AC power wire terminals are located near the top of the instrument
boards. The analog signal terminals are located near the bottom of the instrument boards.
Maintain this separation of the wires to insure the best protection from electrical noise. If the
wires need to be run parallel with any other wiring type(s), maintain a minimum 6 inch space
between the wires. If wires must cross each other, do so at 90 degrees to minimize the
contact with each other and amount of cross talk. Cross talk is due to the EMF (Electro
Magnetic Flux) emitted by a wire as current passes through it.
2.5.1.4 USE OF SHIELDED CABLE
Shielded cable helps eliminate electrical noise being induced on the wires. All analog signals
should be run with shielded cable. Connection lead length should be kept as short as possible, keeping the wires protected by the shielding. The shield should be grounded at one end
only. The preferred grounding location is at the sensor, transmitter or transducer.
2.5.1.5 NOISE SUPPRESSION AT THE SOURCE
Usually when good wiring practices are followed, no further noise protection is necessary.
Sometimes in severe environments, the amount of noise is so great that it has to be suppressed at the source. Many manufacturers of relays, contactors, etc. supply "surge suppressors" which mount on the noise source.
For those devices that do not have surge suppressors supplied, RC (resistance-capacitance)
networks and/or MOV (metal oxide varistors) may be added.
Inductive Coils - MOV's are recommended for transient suppression in inductive soils connected in parallel and as close as possible to the coil. See Figure 2-2. Additional protection
may be provided by adding an RC network across the MOV.
Contacts - Arcing may occur across contacts when the contact opens and closes. This results
in electrical noise as well as damage to the contacts. Connecting a RC network properly
sized can eliminate this arc.
For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad capacitor
(1000 volts) is recommended. For circuits from 3 to 5 amps, connect 2 of these in parallel.
See Figure 2-3.

2.5.2 SENSOR PLACEMENT (THERMOCOUPLE OR RTD)
Thermocouple lead resistance should not exceed 300 ohms. If this is exceeded, instrument
accuracy could be affected.
Two wire RTD's should only be used with lead lengths less than 10 feet.
If the temperature probe is to be subjected to corrosive or abrasive conditions, it should be
protected by the appropriate thermowell. The probe should be positioned to reflect true
process temperature:
In liquid media - the mose agitated area.
In air - the best circulated area.
THERMOCOUPLE LEAD RESISTANCE
Thermocouple lead length can affect instrument accuracy, since the size (gauge) and the
length of the wire affect lead resistance.
To determine the temperature error resulting from the lead length resistance, use the following
equation:
Terr = TLe * Lwhere; TLe = value from appropriate Table
L = length of leadwire in thousands of feet.

Example
A recorder is to be located in a control room 660 feet away from the process. Using 16 AWG,
Type J thermocouple, how much error is induced?
12
Terr = TLe * L = 4.93 (°F/1000 ft) from Table 2.
Terr = 4.93 (°F/1000 ft)
Terr = 3.3 °F
RTD LEAD RESISTANCE
RTD lead length can affect instrument accuracy. Size (gauge) and length of the wire used
affects lead length resistance.
To determine the temperature error resulting from the lead length resistance, use the following
equation:
Terr = TLe * Lwhere; TLe = value from Table 3 if 3 wire or Table 4 is 2 wire.
Example
An application uses 2000 feet of 18 AWG copper lead wire for a 3-wire RTD sensor. What is
the worst-case error due to this leadwire length?
Terr = TLe * L
TLE = +/- .46 (°F/1000 ft) from Table 1
Terr = +/- .46 (°F/1000 ft) * 2000 ft
Terr = +/- 0.92 °F

Configuration 3.1
After completing installation and wiring of the instrument the configuration (set up) procedures
must be performed to prepare the instrument for operation on the intended application. The
procedures include selecting specific parameters, entering data and possible jumper positioning. Once properly configured the instrument will retain the user selections in memory so this
procedure need not be repeated unless required by changes in the application.
Parameter selections and data entry are made via the front keypad. To ease configuration
and operation, user entered data has been divided up into several sections referred to as
modes. Each mode contains a different type of data or may be used for specific operating
functions. For two pen instruments, some modes are common to both pens. These modes are
as follows:

Appendix A-1, page
67, for hardware
lockout information)
Associated with each mode is a series of unique displays that are accessed via the front
keypad.
21
Prior to first time operation of the instrument, the configuration procedures for the Program
and Tune modes must be performed as applicable. Calibration and Test modes are not used
as part of the instrument configuration or operation. These are used for service and maintenance functions and are discussed in Section 5.4 & 5.5 of this manual (page 56 - 66).
Shipped Configuration/Jumper Positioning 3.2
Each instrument is factory shipped ready to accept a thermocouple input on TB 4 and TB 5.
All parameters in each mode are set to default values. These defaults are shown in tabular
form after the description for each mode. Instrument AC power input is as specified in the
instrument model number and is shown on the ratings label. The 230 VAC option includes a
switch in the instrument for selecting either 230 VAC or115 VAC input power. If this feature is
provided, verify AC input and switch position before applying power to the instrument.
3.2.1 JUMPER POSITIONING
Jumpers are used to condition the sensor inputs and to provide a security lockout feature. All
jumpers are located on the instrument Processor board. The instrument board layout and
jumper locations and functions are shown in Appendix A-1 (page 67). Check the jumper
positions in the instrument and verify that they are in the proper position for the intended
application.
The sensor input jumpers JU4, JU5, JU6 and JU7 condition the sensor input signals
and must be used in conjunction with input type selections made in the Program mode.
(page 28).

Operation Summary 3.3
3.3.1 MODE SELECTION
If the instrument is either in the Off mode or the Control mode, repeated pressing and
releasing of the SCROLL key will cause the instrument to display the code corresponding to
each mode that is enabled. To enter a mode while the code is displayed, press the DOWN
key. If a mode does not appear, refer to the Enable mode section for information on how to
determine if the mode is on.
Entry into any mode except the Control, Tune, Manual and Enable modes, will cause the
output(s) to turn off and any process re-transmission value output(s) to be 0 %.
Start up Procedures 3.4
All configuration parameters are listed in Tables 3-1 through 3-4.
For a single pen instrument, parameters for each mode are displayed in the upper right
display. If the instrument being configured is a two pen model, a sequence of applicable
parameters will be displayed in the Pen 2 display after the Pen 1 parameters have been
reviewed and configured. After the Pen 2 parameters have been completed, parameters
common to both pens will be configured and displayed in the Pen 1 display.
The instrument is provided with a time out feature. If the instrument is in any mode (except
while executing a calibration or test procedure) and no keypad activity takes place for 30
seconds, the instrument will time out and exit the mode automatically. The display will become
the code for the respective mode. If a mode code is displayed for 5 seconds with no keypad
activity, then the time out will cause the instrument to proceed to either the Control or Off
mode, depending upon whether the mode entered was an operational mode (Tune, Manual,
Enable) or non operational mode (Test, Program, Cal, Profile Entry or Profile Continue).
3.4.1 POWER UP PROCEDURE
Step 1
Verify that all electrical connections have been properly made before applying power to the
instrument.
Step 2A - For instruments with software revision R2.99 and below
Upon power up, 7XXX will be displayed (X representing digits), then XXXX, then XXXX,
identifying the twelve digit model number as defined in the order matrix. Next, the EPROM
part number will be indicated P-XX. After the EPROM part number, the software revision level
will be displayed in the format rX.XX then tSt1, tSt2, tSt3 will be displayed while Test 1
through 3 are executed automatically. Upon successful completion of these tests, CtrL or oFF
will be displayed for about three seconds. The mode displayed will be the mode that the
instrument was in when the power was turned off. During this time the operator may select
another mode (Tune, Manual, Enable) or non-operational mode (Test, Program, Cal).
Step 2B - For instruments with software revision R3.00 and above
Upon power up, a brief flash on all displays (upper and, if equipped, lower) will occur to show
the instrument is "alive". Then 7XXX will be displayed (X representing digits), then XXXX,
then XXXX, identifying the twelve digit model number as defined in the order matrix. Next, the
EPROM part number will be indicated P-XX. After the EPROM part number, the software
revision level will be displayed in the format rX.XX followed by P.dn (if Pen Action on Power
Up, PAPu, in Program Mode is set to 0, pens go to "home" position on power up). During this
display, the decimal point after the "P" will blink to show the mode is active. Upon successful
completion of this routine, CtrL or oFF will be displayed for about three seconds. The mode
displayed will be the mode that the instrument was in when the power was turned off. During
this time the operator may select another mode (Tune, Manual, Enable) or non-operational
mode (Test, Program, Cal).
Step 3
If any error messages are displayed, refer to Section 5.6 (page 60) for a definition of the
error message and the required action.
Front Panel Operation 3.5
3.5.1 DIGITAL DISPLAY AND STATUS LED’S
The digital display provided for each pen has 4 digits and a decimal point. Each digit has
seven segments and is capable of producing numeric characters from 0-9 and certain alpha
characters. The digital display is used to provide indication of process variable as well as
displaying codes used for configuration and operation of the instrument. The display includes
the following Status Indicator LED’s;
MANAmberLights when the Manual StbY mode is on.
OUT1RedLights when Output 1 is on or mADC output selected.

Operation 4.1
4.1.1 OFF MODE
In the Off mode, the instrument control and alarm function (s) are turned off. Process
Retransmission signal(s) remain active. The chart rotation can be selected in the Program
mode to stop or continue to rotate when the instrument is in the Off mode. The pen(s) will
remain active. The Off mode can be entered by pressing and releasing the SCROLL key until
the display reads oFF, then pressing the DOWN key. The display will read oFF and then
current process variable at two second intervals. Entering the Off mode of a dual pen
instrument will cause both pens to enter the Off mode. The second pen display will be blank
as the upper display reads oFF and displays the process value for the second pen at the
same time as the upper display.
4.1.2 CONTROL MODE
In the Control mode, the instrument control function(s) and alarm(s) are actively responding to
the process variable as selected in the Program and Tune modes and the chart will be
rotating at the rate selected. The Control mode allows setpoint changes form either local
setpoint (standard) adjustment by an operator at the front keypad or from remote setpoint
source (optional). Other operations in the Control mode include a lamp test and proportional
output display.
4.1.2.1 LOCAL SETPOINT OPERATION
Single Pen Instruments: The instrument must be in the Control mode to allow setpoint value
to be displayed and adjusted. In the Control mode, to view the setpoint, press and release the
UP and DOWN key. The green LED under the SP label will light to indicate that the displayed
value is the setpoint. To change the setpoint value, press and hold the appropriate key.
Press and hold the UP key to increase the setpoint or press and hold the DOWN key to
decrease the setpoint. The setpoint will change slowly at first, then faster as the key is held.
If the setpoint will not increase, check the Program mode to see that you are not trying to
increase the setpoint above the setpoint upper limit SPuL. If the setpoint will not decrease,
check the Program mode to see that you are not trying to decrease the setpoint below the
setpoint lower limit SPLL. If the setpoint will not increase or decrease, check that the Setpoint
Change mode is On in the Enable mode.
42
Dual Pen Instruments: The setpoint of each instrument can be reviewed separately. Pen 1:
To review and change the local setpoint for Pen 1, press the UP key. The green LED in the
upper display will light indicating that the setpoint value is displayed. The setpoint can now be
raised by pressing and holding the UP key or decreasing by pressing the DOWN key. Pen 2:
The setpoint for Pen 2 is viewed and changed in the same manner, except the DOWN key
must be pressed to access the Pen 2 setpoint. The setpoint will change slowly at first, then
faster as the key is held. If the setpoint will not increase, check the Program mode to see that
you are not trying increase the setpoint above the setpoint upper limit SPuL. If the setpoint
will not decrease, check the Program mode to see that you are not trying to decrease the
setpoint below the setpoint lower limit SPLL. If the setpoint will not increase or decrease,
check that the Setpoint change mode is On in the Enable mode.
4.1.2.2 REMOTE SETPOINT OPERATION (OPTIONAL)
Dual Pen Instruments: The Remote Setpoint Option is only available on the second pen of a
dual pen instrument. To use this option, if available, the Program mode selections must be
properly made. The Remote Setpoint parameter rSP must be selected as a 1 or 2 as needed.
The Remote Setpint Upper rSPu and Lower rSPL parameters need to be selected for the
application. Pen Profiling Configuration parameter PPC must be selected as 1 Pen Profiling
only. The Remote Setpoint signal is connected to the TB5 terminals as whon in Section 2 of
this manual.
Digital Communications: The setpoint can be adjusted from a supervisory computer system.
Dual pen instruments are capable of having independent setpoint adjustments for each pen.
4.1.2.3 PROFILE CONTROL OPERATION
To start a profile, press and release the SCROLL key until the number of the profile that is to
be started is displayed. With the desired profile number displayed, press either the DOWN or
the RUN/HOLD to start the profile. RUN will be displayed for about 2 second to indicate that
the profile is starting. The status lamps will indicate which segment is active and if in the ramp
or soak portion of the segment.
To stop a profile that is running, press the RUN/HOLD key. The display will who hold for
about 2 seconds, then the process value for about 2 seconds and then continue to display this
sequence. The profile timer will stop but the control, alarm and event outputs will remain
active. The profile can be restarted by pressing the RUN/HOLD key. To exit the profile, press
and release the SCROLL key until the display shows oFF or CtrL, then press the DOWN key.
Pressing the DOWN key with oFF displayed will cause the control, alarm and events to be
turned off. Pressing the DOWN key will CtrL displayed will abort the profile and begin
controlling the process automatically at the last setpoint value. Event outputs remain in the
state (on or off) that they were in prior to aborting the profile.
While a profile is running, it is possible to display additional profile status information. To
activate the Profile Execution Status Display sequence, hold the DOWN key and press the
SCROLL key. This will cause the display to sequence through the following series of display
codes and values:

4.1.2.4 ON-OFF CONTROL
On-Off control can only be implemented on controllers provided with SPST relay or SSR
driver output(s). On-Off operation can be assigned to either or both output 1 and 2 for each
pen. The On-Off control can be selected as direct or reverse acting. Direct action is typically
used in cooling applications. The output device will turn On when the process value is greater
than the setpoint. Reverse action is typically a heating application. The output device will turn
On if the process value is below the setpoint. A hysteresis adjustment is provided for On-Off
outputs on each pen. This adjustment is in terms of degrees/engineering units and defines
the width of the hysteresis band about the setpoint. This parameter may also be referred to
as a deadband. Relay chatter can be eliminated by proper adjustment of this parameter.
When operating in On-Off control, the control algorithm will turn the output On or Off depending upon the setpoint, the relative position of the process value, and the hysteresis adjustment. The respective OUT1 or OUT2 indicator for the respective pen will illuminate to indicate
that the output device is On.
4.1.2.5 TIME PROPORTIONING CONTROL
Time Proportioning Control can be implemented on controllers provided with SPST relay or
SSR driver output(s). Time proportioning can be programed for output 1 and/or 2 for each
pen. Time proportioning control is accomplished by cycling the output On and Off when the
process value is within the proportional bandwidth selected at a prescribed time period. The
time period is selected in the Tune mode by adjusting Ct1 and/or Ct2. The On time is a
percentage of the Cycle Time.
Output On Time = .4 x 20 = 8 seconds
Output Off Time = .6 x 20 = 12 seconds
4.1.2.6 CURRENT PROPORTIONING CONTROL
Current Proportioning control provides a proportional current output in response to process
value and setpoint. The current output can be selected for direct or reverse operation. Direct
current output control is typically used for cooling applications. The current output will
increase as the process value increases within the proportional bandwidth selected. The
reverse current output control is typically used in heating applications. The current output will
decrease as the process value increases within the proportional bandwidth selected.
The instrument can be programmed to provide 0 to 20mADC or 4-20mADC current output(s).
The output selected is dependent upon the final control element being used in the process.
The output 1 and/or output 2 LED will be lighted whenever the Current Proportional outputs
are selected.
4.1.2.7 POSITION PROPORTIONING CONTROL
Position Proportioning control can be implemented on those controllers provided with two
SPST relay outputs or two SSR Driver outputs and Slidewire Feedback option for the respective pen. This control implementation can be performed on each pen.
Position proportioning control permits the use of PID control where the final control element is
a modulating device such as a motorized valve. In this form, each of the two required relays
or SSR Drivers will be used to control the valve. One output will be used to open the valve,
the other is used to close the valve. The slidewire feedback is used to provide a signal
relative to the valve armature position to the instrument.
As with the other proportioning control forms, the process input, tuning parameters and the
setpoint are used by the control algorithm to calculate the output % required to correct for the
deviation between setpoint and process.
45
Proportional Output 1 Action P1EC on error condition does not apply to position proportioning
control. In an error condition, the unit goes only to 0% output (fully closed).
With Position Proportioning control, it may be necessary to adjust the Sensitivity Tune SEnS
mode parameter to reduce or eliminate oscillations of the motor around setpoint. If oscillation
occurs, increase the SEnS value until the motor stops oscillating. If the differential between
the Open and Closed rotation is too large, then decrease the SEnS value. Also, for proper
Position Proportioning operation, it is necessary to specify the actuation time of the valve or
damper from full open to full closed. If the motor has a stroke duration of 60 seconds, change
the value in the Cycle Time parameter Ct1 to 60. This ensures that controller will move the
motor for the proper amount of time when making adjustments.
4.1.2.8 PROPORTIONAL OUTPUT PERCENTAGE DISPLAY
While in the Control mode, pressing the UP and the SCROLL keys at the same time will
cause the display to sequence through a series of display codes and values:
Po1Percent Output (if applicable)Output 1% value
Po2Percent Output (if applicable)Output 2% value
ProcProcess ValueActual Process Value
Each code and output value will be displayed only if the corresponding proportional output is
present. Each code or value will be displayed for 1 second. This sequence of displays will
continue until the SCROLL key is pressed, which will then return the display to the normal
mode. Displays will sequenced for both Pen 1 and 2 as applicable on dual pen instruments.
4.1.3 MANUAL MODE FOR PROPORTIONAL OUTPUTS
Manual adjustment of the proportional output(s) can be used to test the operation of the
output(s), while tuning to establish basic process control, or to provide control of the proportional output(s) during the occurrence of certain error conditions.
Note: The proportional outputs do not change automatically in response to changes in
the process while in the Manual mode. Be sure to pay close attention to the process to
avoid damage.
To enter the Manual mode, press and release the AUTO/MAN key for the specific pen. If the
Standby mode is On in the Enable mode and a control output is selected for proportional
control, the instrument will enter the Manual mode. The Manual mode status LED will light for
that pen to indicate that the Manual mode is in use. Shifting from the Control to the Manual
mode is bumpless. The proportional output(s) will stay at the last value(s) calculated by the
control algorithm. Po1 will appear on the display if output 1 is a proportional output or Po2 if
output 1 is not a proportional control.
In order to vary a proportional output value, press and release the SCROLL key until the
display code for the output is displayed, Po1 or Po2. Press the SCROLL key again to see the
percentage of output value. Press the UP key to increase the output percentage value. Press
the DOWN key to decrease the output percentage value.
If no keys are pressed, the display will sequence through the following displays:
Po1 if output 1 is 3, 4, 5, 6, 7 then the output 1 percentage of output value
Po2 if output 2 is 3, 4, 5, 6, 7 then the output 2 percentage of output value
46
Proc will be displayed then current process value for that pen
In order to change a proportional value once the cyclic display begins, press and release the
UP or DOWN key then press the SCROLL key until the display code for the output displayed
is Po1 or Po2. Press the SCROLL key again to see the percentage of output value. Press
the UP key to increase the output percentage value. Press the DOWN key to decrease the
output percentage value.
To return to the Control mode of operation from the Manual mode, press the specified AUTO/
Man key. If the Automatic Transfer feature is selected in the Program mode, the instrument
will switch from Manual mode to the Control mode when process value reaches the setpoint
value.
Alarm Operation 4.2
There are two alarms available per pen. The type of alarm is selected in the Program mode
as follows:
1. Process Alarm Direct - the alarm will be On if the process value is greater than the process
value selected.
2. Process Alarm Reverse - the alarm will be On if the process value is less than the process
value selected.
3. Deviation Alarm Direct - the alarm will be On if the process value is greater than the
setpoint plus the deviation value selected.
4. Deviation Alarm Reverse - the alarm will be On if the process value is less than the
setpoint plus the deviation value selected.
5. Deviation Band Alarm Open Within - the alarm will be On if the process value is greater
than one half the deviation band alarm values selected above or below the setpoint.
6. Deviation Band Alarm Close Within - the alarm will be On if the process value is less than
one half the deviation band value selected above or below the setpoint.
The alarms will be active while the instrument is in the Control mode. Relay and solid state
relay drivers can be assigned to provide output capability for the alarm functions.
The alarm value (Process deviation or bandwidth) is selected in the Tune mode.
Alarm outputs chatter can be reduced by using the hysteresis for the alarm output adjustable
in the Program mode to create a deadband around the alarm point.
47
Tune Mode Operation 4.3
Proportional output controllers may require the adjustment (tuning) of the PID and other
related parameters. This provides a means for the instrument's control algorithm to be
adjusted to meet specific application requirements.
4.3.1 SYSTEMATIC TUNING METHOD
1. Changes in tuning parameters should be made one at a time.
2. After making any changes in tuning parameters, a disturbance should be introduced into
the process so that the process reaction may be observed. This process reaction, or
recovery, will tell whether the tuning parameters provide the desired control. It is usually
easiest to make a step change in setpoint to introduce this disturbance.
3. The change in setpoint or disturbance, referenced above should be large enough to cause
an observable deviation of process from setpoint. However, this change should not be so
large that it will cause the controller output to proceed to either extreme limit.
4. Controller tuning for optimal control is not hard and fast, BE PATIENT: The process will
take a certain amount of time to react to the setpoint changes during tuning. The amount
of time depends upon the specific process, however, a period of 8 to 12 minutes should
be allowed between changes. The important point to remember is to allow the process to
react completely, do not rush through tuning of the controller. If the complete process
reaction is not observed, optimum control may never be achieved.
5. Time Proportioning control output(s) require the cycle time to be adjusted for the
application. Short cycle times typically result in the most accurate process control, but will
cause the quickest "wear out" of any mechanical components.
6. Leave all other tuning parameters (except for the alarm settings) at the factory default
settings. Obtain the best possible process reaction by adjusting the Proportional Band
width parameter. The setting that achieves the best response for the process should be
left in the controller programming, and should be noted on the Software Reference Sheet
in Appendix E (page 78).
7. If there are to be no setpoint or load changes in the process, the Proportional Band
adjustment may be all that is necessary for proper control. If an offset still exists (the
process does not settle out at setpoint for the best possible proportional band adjustment),
Manual Reset may be added to eliminate this offset.
8. Auto Reset may be added to eliminate process offsets with respect to setpoint. Increase
Auto Reset from 0 to 0.2 increments. Start with a small amount. Increase this increment if
there is no apparent reaction. Remember to allow the process 8 to 12 minutes to react to
any changes.
9. If necessary, Rate may be added. Rate is a dynamic tuning parameter. Rate may be
required to compensate for load changes or to inhibit process oscillations that occur when
a large amount of auto reset (4 or 5 repeats/minute) is being used.
10. Controller tuning is not hard and fast. It may be necessary to adjust the tuning
parameters over a period of time to obtain optimal control of the process.
4.3.2 ZIEGLER NICHOLS TUNING METHOD
This procedure has been determined empirically to yield ideal 1/4 amptitude decay tuning
parameters that are determined by watching the system in a sustained oscillation (curve C,
page 44, the ultimate proportional band and ultimate time period) and then using these values
from this sustained oscillation to calculate ideal parameters.
48
To aid in determining the process oscillation, the instrument configuration parameters can be
adjusted. By reducing the chart upper value Cru and increasing the chart lower value CrL,
the resolution of the oscillation can e better observed. Also the chart rotation time Crt can be
reduced to improve the observation of the oscillation cycle time.
Determining Ultimate Proportional Band and Ultimate Time Period
1. Set Manual Reset rSet to 0.0, set ArSt to 0.0 and set rAtE to 0.0.
2. Enter the Control mode of operation, observe the process reaction.
3. Set the Proportional Band (PB) at 100 and upset the process and observe the response.
One easy method for imposing the upset is to move the setpoint for a few seconds and
then return it to its original value.
4. Achieve a response curve similar to the sustained oscillation (curve C), this is the Ultimate
Proportional Band (UPB) and Ultimate Time Period (UTP).
a) If the response curve from step 3 does not damp out, as in curve A from the
drawing, the PB is too low. The PB should be increased and step 3 repeated.
b) If the response in step 3 damps out, the PB is too high. The PB should be
decreased and step 3 repeated.
These values obtained for Ultimate Proportional Band (UPB) and Ultimate Time Period (UTP)
are used to calculate ideal P, PI, PD, PID tuning parameters using the following ZieglerNichols equations:
Proportional only control (P)P (Pb) = 2 x UPB (degrees or units)
Proportional plus automatic reset (PI)P (Pb) = 2.2 x UPB (degrees or units)
I (ArSt) = 1.2 / UTP (repeats per minute)
Proportional-plus-derivative (or rate) (PD)P (Pb) = 1.7 x UPB (degrees or units)
D (rAtE) = UTP / 8 (minutes)
Proportional-plus automatic reset-plus
derivative (PID)P (Pb) = 1.7 x UPB (degrees or units)
I (ArSt) = 2 / UTP (repeats per minute)
D (rAtE) = UTP / 8 (minutes)
If an over damped response is desired, multiply the proportional band by two.

the line for one second. Next the transmitter will change the logic level to 0 for one second.
Then the transmitter will disable for one second. In the rEC (receive) mode, the transmitter is
continuously disabled. In either mode, the instrument will monitor the line and display rEC1
when a logic 1 is on the line or rEC0 when a logic 0 is on the line . In the SEnd mode, the
instrument will display rEC when the transmitter is disabled. To perform an internal test and
verify the basic operation of the hardware, place the instrument in the Send mode and verify
that the display cycles through rEC1, rEC0, and rEC. To verify that the transmitter functions
properly, two LED’s, each with a current limiting resistor, can be connected with opposite
polarity observed to the TB 2 terminals 1 and 2. The following three states should be observed: one LED On, then the other LED On, then both Off. Alternately, a load resistor can be
placed on the terminals, and observe that the voltage generated across the load resistor is as
follows: >+3 VDC, then >-3 VDC, and then 0 VDC.
Another method, to test the communications hardware, would be to connect one or more
instruments in the Receive mode to an instrument in the Send mode. All of the instruments in
the Receive mode should have their displays alternating in sync with the instrument in the
Send mode. When the sending instrument displays rEC, the receiving instruments should
display rEC1. To terminate the test, press the SCROLL key for one second. Upon exit, tStA
will be displayed. The existence of the communications hardware is dependent on the
hardware configuration.

Glossary
Assured Soak
The instrument may be programmed to interrupt the Profile Soak segment if the process value
exceeds a selectable deviation from setpoint value. The Profile will restart from where it was
stopped when the process value does not exceed the deviation value selected from setpoint.
Automatic Reset (Integral)
This parameter is used so that the instrument will compensate for process variable deviations
from setpoint that occur when the process load characteristics change. Instructions for
determining the automatic reset settings are given in Section 4.3 (Page 48). Factory default
is.0.0. Display code ArSt.
Automatic Transfer
This feature, if configured, allows manual control of the process until setpoint is reached, at
which point the controller automatically transfers from manual to automatic control. Factory
default value is 0 = no auto transfer. Display code AtFr.
Bumpless Transfer
This feature prevents step changes in proportional outputs when changing from automatic to
manual control only.
Cycle Time
This Tune mode parameter is used to select the on/off cycle time for time proportioning
outputs (Ct1 for Output 1 and/or Ct2 for Output 2).
When usng the Position Proportioning option, Ct1 must be selected for the stroke time of the
motor.
Display Filter Factor
This parameter is adjustable from 1 to 20 which represents the number of scans per second
of the process variable that are averaged together before updating the displayed and recorded value. The factory default value is 1 = no filtering. Display code dFF.
Engineering Units Upper and Engineering Units Lower
These Program mode parameters are used with volt, millivolt, and milliamp inputs. The
Engineering Units Upper Euu should be selected as the value to be displayed when the input
is at maximum. The Engineering Units Lower EuL should be selected as the value to be
displayed when the input is at minimum.
First Output Position
This parameter is adjustable from -1000 to 1000 units and represents a shift or offset of the
on-off actuation points or proportional band for the first output relative to the normal position.
For example, a negative value could be used to offset an expected overshoot. First Output
Position also shifts the proportional band with respect to the process value range outside of
which integral action is inhibited. Factory default is 0. Display code FoP.
Hysteresis
This parameter is adjustable from 0 to 300 units representing the width of the band (half
above and half below setpoint). Used with ON/OFF or Alarm outputs to reduce cycling. For
instance, with a value of 4 and a setpoint of 70 the output will turn ON when the process
variable drops to 68 and stay ON until 72 is reached, then turn OFF the output. Factory
default = 3. Display code HyAo for Alarm outputs. Display code HyCo for ON/OFF Control
outputs.
Input Correction
This parameter is adjustable from -300 to 300 units and is used as a method to compensate
for a linear sensor error. Factory default is 0 = no correction. Display code iCi1, iCi2.
71
Input Correction
This parameter is adjustable from -300 to 300 units and is used as a method to compensate
for a linear sensor error. Factory default is 0=no correction. Display code iCi1 and iCi2.
Manual Reset
This parameter is adjustable from -1500 to 1500 units representing a manual shift of proportional band(s) relative to the normal position which is an even strattle of the setpoint. Manual
reset is intended to be used when automatic reset is not used to allow compensation for
deviations from setpoint which remain after the process has stabilized. Factory default is 0.
Increasing the value increases the process variable, i.e. if the process variable stabilizes too
low, increase the manual set. Integral action, and conversely reset-windup inhibit apply over
the same process value range regardless of the manual reset value. Display code rSEt.
Pen Action on Power Up
This parameter specifies whether the pen, on a power-up will drive to the "Home Position"
(center of chart), then return to its correct postion. This is done as a cal check. Settings are
0=go to "home" and 1=remain in last position prior to power down. Default is 0.
Platen
The flat surface in the instrument upon which the chart rotates.
Position Proportioning Sensitivity
A percentage of the first output proportional band width (Pb1).
Process Filter Factor
This parameter is adjustable from 1 to 20 which represents the number of scans per second
of the process variable that are averaged together before updating the process value used for
control purposes. The factory default value is 1 = no filtering. Display code PFF.
Process Retransmission Output
Allows re-transmission of the process variable. Factory default is 0 = not selected. Display
code Pout. If selected, must be assigned to a current output and scaled using Process Output
upper and lower values.
Process Output Upper and Lower Values
(Used in conjunction with process retransmission output)
These parameters specify the process value range over which the assigned current output will
vary in a linear manner from 100% to 0%. If the process value is greater than Pou the output
will be 100%. If the process value is less than PoL the output will be 0%. Factory default
values are 2000 for the upper value and 0 for the lower value. Display codes Pou (upper) and
PoL (lower).
Process Rounding
This parameter is adjustable from 0 to 100 units and is used to round the process value to the
nearest value specified. This is for display only and does not affect the recorded value or
control action. Intended for use where the engineering units span is large, to reduce display
fluctuation. Factory default is 0 = no rounding. Display code Prnd. (e.g. Prnd = 3, Process
Value = -6, -3, 0, 3, 6, 9....)
Proportional Band (PB)
This parameter is adjustable from 1 to 3000 units (not Percent of span) and represents the
process value range where the proportional output is at a percentage of the full output.
Instructions for determining Pb are given in Section 4.3 (page 48) . Factory default is 100
units. Display code Pb1 and Pb2.
Ramp
A Ramp is the section of a profile segment where the setpoint value is being changed from
the initial value to the value selected over the time period selected. The first Ramp of a profile
will take the process value at the time the profile was started as the initial setpoint value.
72
Rate (Derivative)
This parameter is adjustable from 0.0 to 10.0 minutes and specifies how the control action
responds to the rate of change in the process variable. For example, if the process variable is
rising rapidly to setpoint, power is turned off sooner than it would be if the rise were slow. In
effect, derivative action anticipates lags within the system and shifts the proportioning band by
an amount determined by the rate of change of the input sensor.
Magnitude of the shift is determined by a derivative time constant. If the time constant is, say,
.1 minute (6 seconds), for every unit per second rate of change of the process variable at the
sensor, the proportiong band is moved 7 units in the direction that helps control. Likewise, if
the time constant is 1 minute (60 seconds), for every unit per second rate of change of the
process variable at the sensor, the proportioning band is moved 60 units in the direction that
helps control. Factory default is 0.0 Display code rAtE.
Second Output Position (SoP)
This parameter is adjustable from -1000 to 1000 units and represents a shift or offset of the
on-off actuation points or proportional band for the second output relative to the normal
position. A positive value creates a gap where no control outputs are on, a negative value
creates an overlap of control outputs (if the first output position is at the normal position).
Second Output Position also shifts the proportional band with respect to the process value
range outside of which integral action is highlighted (reset-windup inhibit). Factory default is 0.
Display code SoP.
Segment
A segment refers to a part of a profile. A segment consists of a Ramp and a Soak section.
Soak
A Soak is the section of a profile segment where the setoint value is at a constant value for
the time period selected.

The Profile Development Worksheet is intended to assist the Profile Recorder Controller
customers. By filling in the worksheet with the application requirements, profile information
can easily be obtained for entry into the instrument. The worksheet is a convenient record of
the profile for future use.
A profile is a programmed sequence of setpoint changes over a period of time (Ramp) and
setpoint maintained at a single point for a period of time (Soak). A sequence of a ramp and a
soak is referred to as a Segment. A profile can contain from 1 to 6 segments. The instrument
can store in memory up to 8 profiles.
The profile controllers can provide timed output relay action while running a profile, this is
called an Event. Events may be selected as on or off as needed during each Ramp and Soak
segment of the profile.
The first step to completing the worksheet is to determine the range of the setpoints necessary for the application. Fill out the setpoint scale along the left side of the worksheet. For dual
pen profile controller be sure to scale the setpoint range for the greater range. Remember that
the profile ramp will start at the process value indicated when the profile is initiated.
The next step is to sketch the profile outline on the worksheet. Use the setpoint scale to
determine the setpoint levels. Draw each profile separately on a dual pen instrument. Be sure
to fill in the time periods for each part of the segment in the boxes provided at the top of each
column. The Ramp and Soak time boxes are located at the top of each column below the
setpoint boxes for the segment. There are boxes at the bottom of each column to indicate the
status of events, if used. If more than six segments are needed for the profile then individual
profiles can be linked to preform sequentially. Linked profiles operate like one long profile.
Profile program information is easily determined by completing the Profile Developmental
Worksheet for the application. The information derived within the worksheet is directly related
to the profile entry parameters of the profile controller.
