Combined fault and voltage indicator

摘要

A combined fault and voltage indicator includes a rotatably-mounted target viewable from the exterior of the indicator for indicating the occurrence of a fault and a lamp viewable from the exterior of the indicator for indicating system operating voltage. The target is positioned in a reset-indicating state by a reset circuit which periodically energizes a first winding to position a permanent magnet mounted for rotation with the target. Upon occurrence of a fault circuitry within the indicator energizes a second winding to reposition the target to a fault-indicating position. The lamp is caused to flash at a rate which indicates the operating voltage of the system.
