ABSTRACT:
Apparatus and method for monitoring parallel loads on a common supply. An intermittent AC current is supplied to a plurality of load devices disposed in parallel on the common supply. A current sensor senses the current supplied to the load devices and provides a corresponding signal to a comparator. The comparator compares the sensed current with two values: a threshold load level of current corresponding to the operation of the plurality of load devices, and a threshold current level. An error signal is generated by a controller if the sensed current level is less than the threshold current level and if the sensed current is less than the threshold load level.
