Assigning RTDs
After the control mode and parameters have been set tap Setup|RTDs window to assign RTDs to
the circuit. When in PASC control mode you have the option of setting up to four RTDs for ambient
sensing PASC control. In this mode you can have up to three of the four RTDs set to monitor the
pipe. For detailed information on the RTD window refer to 2.2.3 Assigning and Sharing RTD Control
and Monitoring on page 30. Input from an external dry contact may also be assigned to override the
system. Refer to Appendix Section 5.3, page 130 for further details.

Note:
Temperature alarms can only be associated to line monitoring RTDs.
Tap the Alarms button (only shown when line monitoring RTDs are assigned.)

High Line Temp Alarm:
If any RTDs assigned to a circuit measures a temperature above this
threshold, the ACS-UIT2 generates an alarm. The limit can be set for any temperature value you
desire for your application within the range allowed.
Range:
