  • Page 22 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 NGC-30 program takes no action. At 20 mA or more leakage, an alarm is indicated and logged to the Events List. •...
  • Page 23 Input Power Limit – This input is enabled only when SSR control devices are detected (NGC-30-CRMS panel). A Power Limit setting less than 100% will limit the “on-time” of a constant wattage heater to the percentage indicated in the entry window. This has the effect of lowering the amount of power that the heater can produce.
  • Page 24 Setpoint, NGC-30 Control System determines whether to leave the heater On or turn it Off. If the Update Interval time is set to 10 minutes, the NGC-30 control system turns ON the heater every 10 minutes. On time duration when no additional heat is required is as follows: •...
