Input Wiring Recommendations
Use multicolored stranded shielded cable for analog inputs.
Watlow Anafaze recommends that you use 20 AWG wire
(0.5 mm
2
). If the sensor manufacturer requires it, you can
also use 24 or 22 AWG wiring (0.2 mm
2
). Most inputs use a
shielded twisted pair; some require a 3-wire input.
Follow the instructions pertaining to the type(s) of input(s)
you are installing.
The controller accepts the following inputs without any
special scaling resistors:
•
J, K, T, S, R, B and E thermocouples.
•
Linear inputs with ranges between -10 and 60 mV.
Any unused inputs should be set to SKIP or jumpered to
avoid thermocouple break alarms.
