Additional Details

The sense voltage is applied to the relay input terminals. The applied voltage is amplified and sent to a voltage comparator. The output of the comparator is applied to the processor. The program residing in the CPU performs the measurement function and extends a trigger signal after the set delay time is reached. The relay contacts are of the automatic reset type and the indications are locked, the RESET button provided on the front of the relay allows to erase these locked indications. The TEST button is provided to test relay contacts for tripping and alarm circuits.
