Setup | Pasc Window - Raychem nvent NGC-UIT3-EX Programming Manual

WARNING:
Fire Hazard. A ground-fault alarm means the heating cable has been damaged or improperly installed and must not be ignored.
Disabling the ground-fault trip function reduces safety and could result in sustained electrical arcing or fire. To minimize the risk of fire
if the alarm activates, shut off the power and repair the system immediately.
Low Current Alarm Entry Field
If the relay output currents fall below Low Current Alarm, the NGC-UIT3 will alarm.
Range Elexant 5010i / NGC-20: 0-30 A, where 0 = Alarm Disabled
Default Elexant 5010i / NGC-20: 30 A
Range NGC-30: 0-100 A, where 0 = Alarm Disabled
Default: 30.0A
High Current Alarm Entry Field
If the relay output current is above the High Current Alarm, the NGC-UIT3 alarms and stays in alarm until the high current is cleared,
and the alarm is reset in the Status | Circuit window.
Range Elexant 5010i / NGC-20: 0-30 A, where 0 = Alarm Disabled
Default Elexant 5010i / NGC-20: 1.0 A
Range nVent RAYCHEM NGC-30: 0–100 A, where 0 = Alarm Disabled
Default: 5.0 A
Power Limit Entry Field Use with SSR (NGC-30-CRMS) only
This feature limits the average power available at the output, by allowing the user to set a maximum duty cycle for the Circuit.
IMPORTANT: The heater is switched on and off over a time base of several seconds. For example, an 80% power output
is achieved by switching the heater on at 100% for 800 milliseconds and then off for 200 milliseconds. Instantaneous power
consumption is not limited when the heater is on.
Range: 10–100%
Default: 100%
High Voltage Alarm Entry Screen
If the voltage monitoring module measures line voltage above this threshold, the NGC-UIT3 generates an alarm.
Range: 50 – 305 V
Default: 270 V
Low Voltage Alarm Entry Screen
If the voltage monitoring module measures line voltage below this threshold, the NGC-UIT3 generates an alarm.
Range: 50 – 305 V
Default: 90 V
