APPLIES TO:
Selected Heater
DEFAULT VALUE: 30 mA
VALUE RANGE: 10 to 1000 mA,off
DISPLAY MODE:
Advanced
RESTRICTIONS: None
This function sets the Ground Fault Trip setpoint.
It must be greater than the Ground
Fault Alarm setpoint.
When the Ground Fault Current is greater than or equal to this
setpoint, the heater circuit is opened, the Ground Fault Trip Alarm is activated and a
GROUND FAULT TRIP
message is added to the System Status messages. This is a
latching alarm. When the cause of the alarm has been corrected, locate the alarm
message in the Status Menu and press [RESET]. The value range is in 1 mA increments.
MESSAGE NO:
S1-18
APPLIES TO:
Selected Heater
DEFAULT VALUE: 20 mA
VALUE RANGE: 10 to 1000 mA, off
DISPLAY MODE:
All
RESTRICTIONS: None
This function sets the Ground Fault Alarm setpoint.
It must be less than the Ground
Fault Trip setpoint.
To disable this alarm, set the value to
off
. When the Ground Fault
Current is greater than or equal to this setpoint, the Ground Fault Alarm is activated
and a
GROUND FAULT ALARM
message is added to the System Status messages.
The alarm deactivates when the Ground Fault Current falls below this alarm setpoint.
The value range is in 1 mA increments.
MESSAGE NO:
S1-19
APPLIES TO:
Selected Heater
DEFAULT VALUE: off
VALUE RANGE: 1 to 24 hours, off
DISPLAY MODE:
Advanced
RESTRICTIONS: None
This function sets the frequency at which TraceCheck is activated. TraceCheck is a
feature that exercises the system by automatically applying power to the heater if off
for about 30 seconds. If an alarm condition is detected during this period, the
TraceCheck
™
Alarm is activated and a
ALARM DURING TRACECHECK
message
is added to the System Status messages. If a ground fault is detected, the heater
circuit is opened. This is a latching alarm. To clear the alarm, locate the alarm message
in the Status Menu and press [RESET]. To disable this feature, set the value to
off
.
TraceCheck
™
decreases maintenance by providing an early warning of problems
that would otherwise go undetected until the heater was needed.
MESSAGE NO:

APPLIES TO:
Selected Heater
DEFAULT VALUE: off
VALUE RANGE: 85 to 300 V, off
DISPLAY MODE:
All
RESTRICTIONS: HTR SET VOLTAGE is set to
measured
.
This function sets the Low Voltage Alarm setpoint. To disable this alarm, set the value
to
off
. When the Heater Voltage is less than or equal to this setpoint, the Low Voltage
Alarm is activated and a
LOW VOLTAGE ALARM
message is added to the System
Status messages. The alarm deactivates when the Heater Voltage rises above this
alarm setpoint.
MESSAGE NO:
S1-21
APPLIES TO:
Selected Heater
DEFAULT VALUE: measured
VALUE RANGE: 100 to 600 V, measured
DISPLAY MODE:
All
RESTRICTIONS: None
This function sets the value (100~600V) of heater voltage in the statistics calculation
of the selected heater. When it is set to
measured
, the measured supply voltage
across terminal 2 & 3 on the Control Module is used in the calculation of heater
statistics and low voltage alarm.
