Alarm Explanations
Active
Alarm
Explanation Solution
USER HIGH
AMP ALARM
High Current
Alarm
Active when amperage
value is above High Current Level Alarm
setpoint value.
• Establish correct High Current Level Alarm setpoint Refer to heat trace cable
manufacturer maximum current.
• Enable Soft Start for cases of in-rush current. This can be identified by repeated
alarms at start up.
• Increase High Current Level Alarm delay time.
USER LOW
AMP ALARM
Low Current
Alarm
Active when amperage value is below Low
Current Level Alarm setpoint value.
• Establish correct Low Current Level Alarm setpoint. Refer to heat trace cable
manufacturer maximum current.
• Examine heat trace cable for signs of damage. Low current can be indicative of
heater failure.
• Examine heat trace cable connections for damage or improper installation.
USER HIGH
TEMP ALARM
High Temp
Alarm
Active when process temperature value is
above High Temperature Level Alarm setpoint
value.
• Establish correct High Temperature Level Alarm setpoint.
• If in PID Control Mode: Adjust PID settings.
• If in Manual Control Mode: Adjust power output.
• If in On/Off Control Mode: Adjust deadband hysteresis.
• Examine process for alternate causes of high temperature.
• Disable the circuit affected. If the SSR Alarm is active after doing this, the SSR
has failed closed. Contact factory.
USER LOW
TEMP ALARM
Low Temp
Alarm
Active when process temperature value is
below Low Temperature Level Alarm setpoint
value.
• Establish correct Low Temperature Level Alarm setpoint.
• If in PID Control Mode: Adjust PID settings.
• If in Manual Control Mode: Adjust power output.
• If in On/Off Control Mode: Adjust deadband hysteresis.
• Examine heat trace cable and connections
• Examine process for alternate causes of low temperature. Consider insulation
to minimize heat losses.
USER GFEP
LEVEL ALARM
GFEP Level
Alarm
Active when GFEP detects current leakage
above High GFEP Level Alarm setpoint.
• Establish correct High GFEP Level Alarm setpoint.
• Examine cable connections and verify it is receiving power.
• Examine heat trace cable for signs of damage.
• Disconnect heat trace from panel and perform megohm testing.
VOLTAGE NOT
SET
System Voltage
Set Alarm
Active when System Nominal Voltage has not
been established by user.
• Establish correct System Nominal Voltage in the System Voltage Screen. This
screen requires Administrator access.
HCS ALARM
Over Current
Circuit Fault
Alarm
Active when over current fault is detected. • Examine heat trace cable for signs of damage or fault.
• Examine heat trace cable connections for damage or improper installation.
LCS ALARM
Under Current
Circuit Fault Alarm
Active when under current fault is detected. • Examine heat trace cable for signs of damage or fault.
• Examine heat trace cable connections for damage or improper installation.
RTD1 ALARM
RTD Error Alarm
Active when RTD sensor input signal has
failed.
• Examine RTD for signs of damage. If necessary, replace sensor.
• Examine RTD connections for damage, loose connections, or improper
installation.
GFEP ALARM
GFEP Test Fail
Alarm
Active when Ground Fault Circuit test has
failed by reading incorrect amperage based on
user set system voltage.
• Establish correct System Nominal Voltage in the System Voltage Screen. This
screen requires Administrator access.
• Examine power connections for damage or improper installation.
• Disable circuit(s) and Contact factory
SSR ALARM
SSR Fail Alarm
Active when SSR has failed closed on a
disabled circuit.
• Contact factory. Do not enable circuit.
