Voltage monitoring Three-phase monitor confirms correct sequence and detects failure of any one phase. Phase failure results in a flashing red LED and opening of output relay.
Green LED indicates presence of supply voltage. Only 2 phases are needed for Control operation.
Incorrect phase sequence is indicated by constant red LED and opening of output. A front panel potentiometer adjusts failure indication delay up to 10 seconds.
A low voltage condition (60% of nominal) results in immediate failure indication, red LED and open output. Threshold can be set from 70% to 95% with a second front panel adjustment.
