Ground-fault Alarm and Trip
Ground-fault (GF) current levels are monitored and are displayed in milliamperes. The
adjustable ground-fault level gives the user the choice of both alarm and trip levels
suitable for the particular installation.
Proportional Ambient Sensing Control (PASC)
The C910-485 includes the Proportional Ambient Sensing Control (PASC) mode to
maximize the energy efficiency of the heat tracing system.
Minimum/Maximum Temperature Tracking
The controller maintains the minimum and maximum temperature values measured
since the last reset of these values.
Temperature Alarms
The controller alarms on user selectable low and high temperature limits.
Auto-cycling
The controller will momentarily energize the circuit (for 10 seconds) at a programmable
interval in order to test the heat tracing circuit during periods of non-use. This feature will
detect issues with the heat-tracing circuit before it can lead to system damage.
Temperature Sensor Failure Alarm
Both open and shorted sensors are detected and alarmed by the controller.
Full Digital Communications
The C910-485 incorporates RS-485 serial communication for applications requiring direct
interfacing to BMS systems using Modbus protocol or used as a single circuit extension
to the ACS-30 control system.
