Details - Setpoints
MESSAGE NO:
S1-19
APPLIES TO:
Selected Heater
DEFAULT VALUE: off
VALUE RANGE: 0.5 to 100.0 A, off
DISPLAY MODE: Advanced
RESTRICTIONS: Solid-State Modules Only
This function sets the maximum average current that flows in the heater circuit. It
is useful for limiting the inrush current of self regulating cable or to reducing the
power output of constant wattage heaters. Set the value below the breaker rating or
to the maximum power desired (Wattage = Heater Voltage x Power Limit value).
The value range is in 0.5 A increments.
MESSAGE NO:
S1-20
APPLIES TO:
Selected Heater
DEFAULT VALUE: 50 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. To disable this trip alarm set the value to “off”.
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 5 mA increments.
MESSAGE NO:
S1-21
APPLIES TO:
Selected Heater
DEFAULT VALUE: 25 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 5 mA increments.
MESSAGE NO:
S1-22
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 for a period defined by TRACECHECK HTR ON TIME. If an
alarm condition is detected during this period, then 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.
