If you have questions or require any assistance with your controller or

with any temperature control problem, please contact your Omega rep­resentative or call customer service at 1-800-622-2378. In Mexico and

Unpacking

Carefully unpack the instrument, inspect for shipping damage.
Report any damage to the carrier immediately.

Locating

Select a location for the controller where it will not be subjected to
excessive shock, vibration, dirt, moisture or oil. The ambient tem­perature of the area should be between 30° and 130° F. (Dust, oil,
water resistant cover is available to protect from harsh environ­ments. Contact factory for details.)

Circuits

Consult serial tag on the unit and select power wiring diagram for
the model specified. All wires are connected to the terminals on

ate connections using proper size wire for rated controller load
power circuits. (On -B output model use AWG #14 wire; for -F, -S
and -T outputs use #14, 16, or 18 wire.) The unit can be supplied
with 120 V or 240 Vac, 50/60 Hz. Select proper terminal for the
voltage used.

end, using the corner screw provided for that purpose.

Proper thermocouple placement can eliminate many problems in the
system. The probe should be placed so that it can detect any tempera
ture change with little thermal lag. In a process that requires fairly con
stant heat output, the probe should be placed close to the

heater. In processes where the heat demand is variable, the probe
should be close to the work area. Some experimenting with probe loca
tion can often provide optimum results.

In a bath process, the addition of a stirrer will help to eliminate lags.
Since the

thermocouple is basically a point measuring device, putting more than
one thermocouple in parallel will provide an average temperature read
ing and produce better results in air-heated processes.

The typical control system contains the sensor, controller (4000) and
the process (load). The sensor produces a small signal proportional to
the measured temperature of the process. This signal is amplified by
the controller, where it is compared with setpoint temperature. If the
temperature of the sensor is below setpoint, the output circuitry will be
actuated to apply power to the process. This is indicated by means of
an LED light. The digital meter displays the sensor’s (process) temper
ature, and when switched to right or left, the primary or secondary con
trol setpoints.

Relay Output

contacts can be wired to provide power to a heater within the above
rating. A contactor can be operated to handle a larger load. Solenoids
can be operated to control oil or gas heaters.

The controller operates as a narrow band controller when the band
adjustment is set at the narrow position. As the band is widened, the
unit becomes a time-proportioning controller, which provides close tem
perature control. The percentage of the time when the relay is ener­gized is varied by the controller to meet the load requirements.
Maximim cycle time setting is 15 seconds.

Operation

-F - Current Output

Current proportional output of the -F unit is a 4 to 20 mAdc signal
into 1000 ohm maximum. This output can be used to drive power
controllers, motor positioners or electropneumatic actuators.

-DC - Pulsed Voltage Output

This output is similar to the -F output with the exception of a pulsed
time base rather than a fully proportional current output signal. This
output is designed to drive solid state contactors.

-T - Solid State Output

The -T output unit has a solid state relay with SPST contacts rated
at 1 A, 120/240 Vac (10 A inrush maximum). These contacts can be
wired to provide power to a heater within the above ratings, and a
contactor can be added to handle larger loads. Solenoids can be
operated to control oil or gas heaters.

Layout of the front panel is shown below. To reach the adjustments,

swing the top of the door forward and down. The proportional band

adjustment is on the right side and sets the gain of the controller.

The offset (manual reset) adjustment is on the left and corrects for

offsets from the setpoint temperature. The output indication (LED)
can be seen through a window in the door.

Units ordered with Option A (3-Mode PID) will not have a manual
reset adjustment. Instead, these units have an automatic rate and
reset selector switch on the internal 3-mode board.

Troubleshooting

Symptom

1. Controller dead. No output light, no digital display

Probable Cause

- No line voltage input

- Open PC board to backplate connector (defective con­nector)

- Open power transformer

2. No output, step 1 ok, display reads ambient

3. No output

4. a. Full output, no control. Power light stays on.

4. b. Full output, no control. Power light goes off.

5. Process control temperature differs from setpoint when
read with an external pyrometer. Controller’s display agrees
with setpoint.

6. Temperature overshoots, or oscillates.

7. Process control temperature stabilizes above or below set­point as read on display.

- External backplate jumper missing (all models except
“S” and “F”)

- Defective relay

- Open heater or heater circuit wiring

- Open thermocouple or T/C wiring

- Thermocouple connections reversed

- T/C lead wires shorted between T/C and control

- Relay contacts welded closed

- T/C lead wires shorted close to process

- Wrong type of T/C being used, etc.

- Standard electrical wiring being used in place of T/C
wire

- Gradient error

- Process overpowered

- Bandwidth too narrow

- Process or sensor lag

- Offset (manual reset) incorrectly adjusted

- Partial short to ground in heater when used on
240 V line

- No output from suspect control

- Controller reading other zones of multi-controlled
process

- Full output from suspect control

- Apparent stabilization from other zones of multi-con­trolled process

- Improperly sized heater

15

Check

Verify 120/240 Vac, 50/60 Hz input voltage. Check heater for shorts. Look for open breakers or
open external fuse.

Check continuity through power transformer primary. Remove input power. With ohmmeter, read
between pins: 8 and 9 for 225 or 450 ohms +/-10% and 8 and 10 for 680 or 1000 ohms +/-10%

If no readings in either step above, remove controller from housing and repeat resistance mea­surements as above, but directly on PC board lands corresponding to pins 8, 9, and 10. Correct
readings indicate open PC board to backplate connector problem. Incorrect readings indicate
power transformer problems.

Corrective Action

- Replace heater, if shorted

- Restore power

- Replace either power transformer or backplate connector

Refer to wiring diagram.
Visually inspect relay contacts.
Heater continuity and wiring.

T/C continuity. Disconnect T/C connections from instrument. Measure T/C circuit resistance.
Ohmmeter should read 100 ohms or less.

Connection polarity. T/C wires are color-coded. Red is the negative (-) lead. (for U.S.A.)
T/C lead wiring.

Disconnect power and load. Measure resistance between pins 12 and 13. Should read infinity.

Check T/C lead wires at back of probe
Wire color indicates type of T/C

Verify type of wire
Check out above three items first

Compare “on time” to “off time.” Short on to off time
indicates too much heater capacity for the process

Check bandwidth
Loose heater or sensor fit. Poor relative location.

Offset (manual reset)
Heater to ground resistance

See symptom 2 (no output)

- Install jumper

- Replace relay if contacts are worn or dirty

- Replace open heater, correct defective wiring

- Replace T/C. Correct defective wiring

- Connect correctly

- Repair or replace

- If resistance reading is near 0 ohms, replace relay

- Replace defective wiring

- Install correct T/C for temperature range of instrument. See instru­ment serial number tag for T/C type.

- Run only T/C wire between process and controller.

- Use electronic indicator in parallel with suspect instrument’s T/C
input.

- Reduce total heater power

- Widen band

- Improve fit, locate closer together

- Adjust (+) to increase controlled temp. (-) to decrease temp.

- Replace defective heater

NOTE: Fuse blowing is not caused by the controller. Blown fuses are
caused by shorts in the heater circuit, and must be corrected to pre­vent damage to the controller.
