• Input the High Current Alarm and Low Current Alarm by pressing each of the two numeric
fields in turn. For this example, High Current Alarm is set to 30 A, and Low Current Alarm is set
to 5 A.
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
imPortant:
Setting 0 for both High and Low Current Alarms completely deactivates the Current
Alarm function.
• Power Limit – This 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 field. This has the effect of lowering the amount
of power that the heater can produce.
imPortant:
Power Limiting is not recommended if self-regulating heaters are installed.
step 10: enable or disable the Circuit
Fig. 2.17 Circuit 1 enabled
At the Setup|Circuit window with Circuit #1 selected:
• By default, once you program a Circuit, it immediately begins to control the heater based on the
input information.
• If you do not want this Circuit to activate until all Circuits are programmed, go to Setup | Circuit
window and press the Enabled toggle button once, which disables the Circuit. To re-Enable,
press the Enable/Disable button again.
