9.3.7

GFI Alarm (Continued)

Cause of Alarm:
• Trip setting too close to normal leakage current
• Damaged cable insulation and/or moisture present
• Moisture in junction box
• Poor

splice

or

termination

• Moisture provides conductive ground path which allows

ground fault current

9.3.8

High Voltage Warning/Alarm

This warning/alarms voltage levels that are greater than the
HIGH VOLTAGE WARNING/ALARM setting.

CauseofWarning/Alarm:
• Warning/Alarm setting too close to normal operating voltage
• Incorrect wiring
• Powersurge

9.3.9

Low Voltage Warning/Alarm

This warning/alarms voltage levels are less than the LOW
VOLTAGE WARNING/ALARM setting.

CauseofWarning/Alarm:
• Warning/Alarm

setting

too

close

to

normal

operating

voltage

• Damaged power cable
• Incorrect VOLTAGE TURNS RATIO
• “Brown-out” conditions
• Loss of power to the circuit

9.3.10

Overcurrent Trip

If the controller is unable to start the cable due to high
current

or

after

attempting

to

soft

start

it, the

controller

will

trip its output switch off.

Cause of Alarm:
• Excessive in-rush current
• Incorrect CM-2201/CM2202 settings
• Incorrect wiring
• Damaged cable

Switch Failure

This alarm indicates that the controller senses current flow
when the output switch should
be off.

Cause of Alarm
• Some

other

device

energized

heat

trace

• Output switch has failed “closed”

9.3.11

Power Limiting (Current Limiting)

This alarm indicates that the solid state relay is limiting
the average amount of power that is applied to the trace
circuit as defined by the MAXIMUM POWER setting.

Cause of Alarm:
• Power applied to trace circuit is being limited to the

MAXIMUM POWER setting

9.3.12

EEPROM Data Failure

This alarm indicates that the controller has detected a
failure in its non-volatile memory (this is where all of the
controller’s

configuration

and calibration settings are

stored). This indicates an internal problem and the CM2201/
CM2202 should

be

replaced

and

returned

to

the

factory for

repair.

Cause of Alarm:

• The CM-2201/CM2202 cannot bypass the failed area of its

memory and has loaded factory defaults into this failed area.

9.3.13 Continuity Failure

The “Continuity Failure” alarm indicates that the current
being drawn by the load is less than about 0.5 Amps and
hence the load is assumed to be disconnected.
