Notes:
1. HIGH TEMP TRIP (HIGH HIGH TEMP) If HIGH TEMPERATURE TRIP is ON (OFF), this message will be displayed if the measured temperature rises above a value equal to the HIGH TEMPERATURE TRIP (HIGH) set-point.
2. HIGH TEMP ALARM The measured temperature has risen above a value equal to the HIGH TEMPERATURE ALARM set-point but has not yet risen above a value equal to the HIGH TEMPERATURE TRIP/HIGH set-point.
3. LOW TEMP ALARM The measured temperature has fallen below a value equal to the LOW TEMPERATURE ALARM set-point.

Notes:

5. HIGH CURRENT ALARM The measured heater current rise is higher than the HIGH CURRENT ALARM set-point but not above the HIGH CURRENT TRIP/HIGH.
6. LOW CURRENT ALARM The measured heater current has fallen lower than the LOW CURRENT ALARM set-point.

Notes:
7. HIGH LEAKAGE TRIP (HIGH HIGH GROUND) If GROUND CURRENT TRIP is ON (OFF), this message will be displayed if the measured ground/earth leakage current rises above the GROUND CURRENT TRIP (HIGH) set-point.
8. HIGH LEAKAGE ALARM The measured ground/earth leakage current has risen above the GROUND CURRENT ALARM set-point but not above the GROUND CURRENT TRIP/ALARM2 set-point.
HIGH Current ALARM
The amperage being read on this circuit is above the value programmed as the highest heater operating
current allowed before an alarm condition is reported. The current alarm will automatically clear when the
high heater current alarm event clears. This event is reported as a HIGH Current ALARM.
HIGH-HIGH Current (OPTION TRIP)
The current being read on this circuit is above the value programmed as the highest current allowed before
a TRIP condition is reported. When the current trip is enabled and a reading exceeds the TRIP level, the
event must be acknowledged, and the current level must drop below the TRIP set point value before the
circuit will re-energize. Once the alarm is acknowledged the alarm color message will change from red to
orange. When the trip is not enabled, trip current alarm will automatically clear when the reading returns to
normal condition.
Circuit FAULT ALARM
There are three possibilities could cause a circuit fault condition.
• CAN bus communication interruption
• DCM board is damaged.
• During the SELF-TEST procedure, it is determined that the heater current does not change between
the ON and OFF states.
Ground FAULT ALARM
A ground fault condition is reported if during a TEST-TO-TRIP procedure of applying a test leakage current to
each circuit, it is determined that the test leakage current is not sensed.
Programming Error
This warning message appears when the values that have been programmed for temperature, current, and/
or ground current are in conflict. The programmed values are to be set as follows:
Low Alarm < Maintain Set point < High Alarm </= High-High Alarm (Trip optional)
Warning: It is possible that a heating circuit may turn on even if a programming error exists. For example,
the Maintain SP is set above the High Alarm. The circuit will display programming error, but as soon as the
actual temperature is below the Maintain SP the circuit heater will turn on. (For line-sensing control the
solution is to ensure the High Temp Alarm set point is above the Maintain SP plus control band.)
