Step 5: Review the Fail Safe setting.
Pressing the Fail Safe toggle button alternates the Fail Safe mode between Power Off and
Power On. This selection tells the NGC-30-CRM/-CRMS (5GF-C) if the heater should be
turned on or off if all of the RTD(s) for this Circuit fail.
If the main concern is to prevent pipes from freezing, then Power On is a good choice.
However, if the heater is oversized and overheating is a concern, then Power Off could be
a better choice.
Step 6: Go to Setup|RTDs screen.
The NGC-30 program first checks to see if the default RTD is available. On any NGC-30-
CRM/-CRMS (5GF-C) board, the first RTD input is automatically coupled with the first relay
output; the second RTD is linked with the second output relay, etc.
