WIRING
(for safety, disconnect all power sources prior to wiring)
1. Attach the leads from your sensor to the sensor terminal block, terminals 7, 8 & 9. For a ther-
mocouple, most commonly the red lead is negative (-) negative, attach that to terminal 9. The
positive lead of the thermocouple should be connected to terminal 8.
The TEC-9100 controller is preprogrammed to accept a type J thermocouple. If another sensor
is used, the “INPT” setting has to be revised.
2.
Make sure your service power has been disconnected and locked out.
Please note the enclosed wiring diagram.
Wire your single phase supply to terminals 1 & 2. If you are using three phase power, wire to
terminals 1, 2 & 3.
Connect your heater load to terminals 4 & 5 if using single phase, 4, 5 & 6 if using three phase.
Follow all local and national codes.
Add disconnect and fusing as required.
Before applying power, check tightness of all terminals.
3. An optional NO-NC alarm can be connected to terminals 1, 2 & 3 of the TEC-9100 controller.
This relay is rated at 2 amps, 240 volts. See Alarm Wiring Diagrams on page 6.
OPERATION
1. Refer to the instruction manual provided for complete operation and auto-tuning instructions
for the TEC-9100 temperature controller.
2. Close and secure the door. Switch on the enclosure. Using the up & down pushbuttons on the
TEC-9100 controller, start out with the temperature set low to test your system performance.
If the set point temperature is being maintained, set your desired temperature setpoint.
If your setpoint temperature is
not
being maintained, please refer to the auto-tuning procedure
in the attached manual.
If auto-tuning does not produce the required results, manual tuning may be necessary.
Note: The signal of the output circuit is wired through output 2 of the TEC-9100 which can
be used as a cut-out in the event of an over-setpoint temperature condition. This is
a deviation contact set to 30º F above the setpoint.
In the event of an over-setpoint temperature condition, output 2 will open, cutting
the control signal to the output relay.
This deviation setpoint can be changed by accessing “SP2” in the TEC-9100 (note
following). This is not meant to be a redundant safety controller.
Refer to our TEC-910 for a safety controller.
