The wiring diagram shows connections for a Type J or K
thermocouple wire via terminals. For a long thermocouple
run, the proper thermocouple extension wire must be
used, and the proper polarity must be maintained. If
these precautions are not observed, the unit may not
meet specifications.
Power and thermocouple wire should not be placed in
the same conduit or wiring trough. However, wires from
several thermocouples may be in the same conduit or
wiring trough.
If shielded thermocouples are used, the shields should
be insulated electrically from the thermocouple wires and
terminated to earth ground.
The unit will read “EEE” for over range conditions, and
“---” for under range conditions.
If field calibration is required, a two-point calibration
with a millivolt generator can be used. Allow 30 minutes
for the unit to stabilize before calibrating. Calibrate the
low reading by adjusting the zero pot. Enter the second
calibration higher than the first point and adjust the span.
Recall these two points if needed.
Wiring Diagram Wiring for Different Power Requirements
The figure above illustrates how to wire the relays for the
different power requirements. The relay must have an
external power source for you to be able to control your
device.
