Product Description 1.1

1.1.1 GENERAL

This instrument is a microprocessor based single loop controller capable of measuring,
displaying and controlling temperature, pressure, flow, and level from a variety of inputs.

Control functions, alarm settings and other parameters are easily entered through the front
keypad. All user's data can be protected from unauthorized changes with it’s ENABLE MODE
security system. Battery back-up protects against data loss during AC power outages.

The input is user configurable to directly connect to either thermocouple, RTD, mVDC, VDC
or mADC inputs. Thermocouple and RTD linearization, as well as thermocouple cold junction
compensation is performed automatically. The sensor input is isolated . The instrument can
operate on either 115VAC or 230VAC power at 50/60Hz. It is housed in an extruded alumi­num enclosure suitable for panel mounting. It may be surface mounted using an optional
adaptor.

1.1.3 CONTROL

The instrument can be programmed for on-off, time proportioning, current proportioning, or
position proportioning control implementations depending on the model number. A second
control output is an available option. Proportional control implementations are provided with
fully programmable separate PID parameters.

1.1.4 ALARM

Alarm indication is standard on all instruments. Alarm type may be set as PROCESS DIRECT
or REVERSE (High or Low), DEVIATION DIRECT or REVERSE (Above or Below setpoint), or
DEVIATION BAND TYPE (Closed or Open within the band). Alarm status is indicated by
LED. An alarm output can be provided by assigning any output(s) SPST relay(s) or SSR
Driver(s) to the alarm.

1.1.5 EXTENDED FEATURES SOFTWARE

EA Software Features
Fast Scan Provides an optional faster scan rate of 3 scans per second.

Normal scan is one scan per second.

Process Rounding Provides rounding of the process value displayed to reduce display

fluctuation. For example, the displayed value can be rounded to
the nearest 5 (display -5, 0, 5, 10, etc.). This is for display only and
does not affect the control action.

Extended Current The current outputs available can be extended to include 0-20mA
Output Ranges and 0-5VDC (with the appropriate shunt resistor), rather than the

standard 4-20mA and 1-5VDC outputs.

Process/Setpoint The process or setpoint value can be scaled over any desired
Value Retransmit range and retransmitted using one of the current outputs. (This
Capability precludes the use of the output for control).

Percent Output Provides a relay actuation based upon a proportional output being
Relay Actuation above or below a specified value.

Contact Closure Sensing This feature provides the following action: When a contact closure
for SP=PV is sensed, the setpoint will be set equal to the current process

value. This is only done on the transition from open to closed, and
not continuously while the switch is closed.

EB Software Features
Setpoint Ramp Provides a limitation on how fast the process value will ramp to setpoint by

Rate limiting the rate of change of an internal setpoint used for control versus

the setpoint the operator specifies.

Installation and Wiring 2.1

w

Prior to proceeding with installation, verify the AC power input required by the instrument. AC
power input is either 115 VAC or 230 VAC and is specified in the model number and on the
wiring label affixed to the instrument housing. See Figure 2-4 (page 13) for a wiring label
description.

230 VAC models may be converted to 115 VAC operation by the user, by changing the
position of jumpers soldered on the Power Supply Board, see Appendix A-1 (page 59) for
details.

Electrical code requirements and safety standards should be observed and installation
performed by qualified personnel.

The electronic components of the instrument may be removed from the housing during
installation. To remove the components, loosen the locking screw located in the lower center
of the instrument’s front panel. Pull the entire instrument straight out of the
housing. During re-installation, the vertically mounted circuit boards should be properly
aligned in the housing. Be sure that the instrument is installed in the original housing. This
can be verified by matching the serial number on the unit to the serial number on the housing.
(Serial numbers are located on the inside of the housing enclosure and on the label on the
underside of the front panel)
specifications. The ambient compensator on the rear of the housing enclosure is calibrated to
the electronics of the instrument at the factory.

.

This will insure that each instrument is accurate to its published

Recommended panel opening sizes are illustrated below (Figure 2-1). After the opening is
properly cut, insert the instrument housing into the panel opening. Insert the two panhead
screws provided, through the holes in the mounting bracket into the holes in the rear of the
instrument as shown in Figure 2-1. Firmly tighten the screws. Instruments are shipped
standard for panel mounting. To surface mount, an adaptor is required and should be
specified when ordering. For installation in wash-down areas, a watertight cover is available.

Preparation for Wiring 2.2

2.2.1 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.

2.2.1.1 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 used to isolate the instrument.

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.

2.2.1.2 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. Use a 12 gauge (or heavier) insulated stranded
wire.

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.

2.2.1.3 WIRE ISOLATION

Four voltage levels of input and output wiring may be used with the unit:

• Analog input or output (i.e. thermocouple, RTD, VDC, mVDC or mADC)

• SPST Relays

• SSR driver outputs

• AC power
The only wires that should be run together are those of the same category. If they need to be

run parallel with any of the other lines, maintain a minimum 6 inch space between the wires.
If wires must cross each other, do so at 90 degrees. This will minimize the contact with each
other and reduces "cross talk" "Cross talk" is due to the EMF (electro Magnetic Flux) emitted
by a wire as current passes through it. This EMF can be picked up by other wires running in
the same bundle or conduit.

In applications where a High Voltage Transformer is used, (i.e. ignition systems) the secon­dary of the transformer should be isolated from all other cables.

This instrument has been designed to operate in noisy environments, however, in some cases
even with proper wiring it may be necessary to suppress the noise at its source.

2.2.1.4 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 the sensor, transmitter or transducer.

2.2.1.5 NOISE SUPPRESSION AT THE SOURCE

Usually when good wiring practices are followed no further noise protection is necessary.
Sometimes in severe electrical 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 coils con­nected in parallel and as close a 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.

2.2.2 SENSOR PLACEMENT (Thermocouple or RTD)

Two wire RTD's should be used only 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 most agitated area.
In air - the best circulated area

THERMOCOUPLE LEAD RESISTANCE

Thermocouple lead length can affect instrument 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 * L where; TLe = value from appropriate table below

L = length of leadwire in thousands of feet.

RTD LEAD RESISTANCE

RTD lead length can affect instrument accuracy, since the size (gauge) and length of the wire
affect lead resistance.

To determine the temperature error resulting from the lead length resistance, use the following
equation:

Terr = TLe * L where; TLe = value from Table 3 if 3 wire RTD or Table 4 is 2 wire RTD

L = length of lead wire in thousands of feet

Configuration and Operation 3.1

3.1.1 POWER UP PROCEDURE

Verify all electrical connections have been properly made before applying power to the
instrument.

If the instrument is being configured (set up) for the first time, it may be desirable to discon­nect the controller output connections. The instrument will go into the Control mode following
the power up sequence and the output(s) may turn on. During power up, the seven digit
model number will be displayed. Next, the software revision level will be displayed, followed
by the EPROM tab number. Instrument self test 1 through 3 will take place as they are
displayed. After completion of the tests Ctrl will be displayed for 3 seconds. At this time
another mode of operation may be selected by pressing the SCROLL key.

3.1.2 CONFIGURATION PROCEDURE

Parameter selections and data entry are made via the front keypad. To ease configuration
and operation, the user selectable features have been divided into several sections (modes).
Data and parameter entries are made by stepping through each mode and making an
appropriate response or entry to each step as necessary for the application.
