Step 8: Go to Setup | Electrical
Fig. 2.16 Setup | Electrical
At the Setup | Electrical:
• Input the Ground-Fault Current Alarm and Ground-Fault Current Trip by pressing each of the
two numeric fields in turn.
• For this example, the Ground-Fault Current Alarm and Ground-Fault Current Trip levels are set
to 20 mA and 30 mA respectively.
– At less than 20 mA, the Raychem NGC-30 program takes no action. At 20 mA or more
leakage, an alarm is indicated and logged to the Events List.
– At 30 mA the output relay assigned to this Circuit is tripped off.
High Voltage Alarm Entry Screen
If the voltage monitoring module measures line voltage above this threshold, the NGC-UIT2
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-UIT2
generates an alarm.
Range: 50 – 305 V
Default: 90 V
