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:
Maintain setpoint plus 5°F (3°C) to 90ºF (32°C)
Default:
90°F (32°C)
LOW LINE TEMP ALARM:
If any RTDs assigned to a circuit measures a temperature below this threshold, the ACS-UIT2
generates an alarm.
Range:
0ºF (-18ºC) to Maintain setpoint
Default:
35°F (2°C)
