• Indicator LEDs: Red when Relay is energized; Green when Relay is Off

Overview

The relay energizes (and the LED is Red) when the monitored voltage is above the pick-up setting for a period longer than the fixed pick-up time delay of 0.5 seconds. The relay de-energizes (and the LED is Green) when the monitored voltage is below the drop-out setting for a period longer than the fixed drop-out time delay (t) of 0.5 seconds.
