C.1

Appendix C Summary of Alarms

and their Causes

The Heater Control Temperature is less than or equal to the Low Temperature Alarm
setpoint. For dual RTD Control Modules, the RTD Mode determines how the Heater
Control Temperature is derived.

ü

Check that the alarm setpoint is correct.

ü

Test for correct RTD operation.

ü

Check for damaged insulation or cladding.

ü

Check for damaged heat trace.

ü

Check the heat trace design.

The Heater Control Temperature is greater than or equal to the High Temperature
Alarm setpoint. For dual RTD Control Modules, the RTD Mode determines how the
Heater Control Temperature is derived.

ü

Check that the alarm setpoint is correct.

ü

Test for correct RTD operation.

ü

Check the heat trace design.

The measured Heater Current, when the heater circuit is on, is less than or equal to
the Low Current Alarm setpoint. For three-phase Control Modules, the individual
phase (A, B or C) is identified.

ü

Check that the alarm setpoint is correct.

ü

For self-regulating heating cable, the current varies substantially with  tempera-

ture. Check that the alarm setpoint accounts for this variation.

ü

Test for correct current measurement.

ü

For parallel resistance heating cable, check for broken cable or failed splice or
tee connection.

ü

For zone-type heating cable, check for failed zones.

The measured Heater Current, when the heater circuit is on, is greater than or equal
to the High Current Alarm setpoint or, the Heater Current is greater than the maxi-
mum value range. For three-phase Control Modules, the individual phase (A, B or C)
is identified.

ü

Check that the alarm setpoint is correct.

ü

For self-regulating heating cable, the current varies substantially with  tempera-

ture. Check that the alarm setpoint accounts for this variation.

ü

Test for correct current measurement.

The measured Heater Current, when the heater circuit is on, is greater than or equal
to the High Current Trip setpoint. For three-phase Control Modules, the individual
phase (A, B or C) is identified.

ü

Check that the alarm setpoint is correct

ü

For self-regulating heating cable, the current varies substantially with  tempera-

ture. Check that the alarm setpoint accounts for this variation.

ü

Test for current transformer failure by measuring Heater Current.

The measured ground fault current is greater than or equal to the Ground Fault
Alarm setpoint or, the ground fault current is greater than the maximum value range.

ü

Check that the setpoint is appropriate for the length and type of cable.

ü

Check for wet or damaged heating cable, power connections, spices or tees.

ü

Test for correct ground fault measurement.
