ASSIGNING RTDS
After the control mode and parameters are set, tap Setup|RTDs window to assign RTDs to the
circuit.
When in external device control mode you have the option of setting up to four inputs through
any RTD inputs in your system. You must have a least one External Control device, and for High
Temperature Override at least one RTD must be assigned. For detailed information on the RTD
window refer to Section 2.2.3 Assigning and Sharing RTD Control and Monitoring on page 30.
Note:
If a RTD is connected to the ACS-PCM2-5, or C910-485, relay the heating cable is assigned in
this mode it must be assigned to high temperature override.
