In such situations, auxiliary contacts in IQ System Controller can be used to disconnect (shed) excess solar or heavy loads. In addition, low-priority loads with high power requirements may deplete energy storage. Auxiliary contacts can be used to shed these large loads to help maintain energy in the storage system.
Normally Open (NO): These contacts are open in the de-energized state of the contactor or relay. When the device is energized and the main contacts close, the normally open auxiliary contacts will also close, completing a separate circuit. Think of it as a switch that’s “off” until the main device turns “on.”
NO1/ NO2 auxiliary contact is not configured. As a result, there will be a voltage drop across NO1/NO2. The contactor is not powered. Diagnosed by measuring AC voltage on the contactor coil. The contactor is not energized. Faulty wiring between auxiliary contact in IQ System Controller and definite purpose contactor.
