Step 5: Review the Fail Safe setting
Fig. 2.13 Setup|Circuit window and Fail Safe button
At the Setup|Circuit window:
• 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 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.
