Mode of Operation - Designed in a small, easy-to-mount, surface mount or DIN rail style case, the ICM409 continuously monitors the incoming line voltage for errors. When the line voltage is appropriate, the ICM409 closes a set of N.O. contacts and lights a green LED. When the incoming voltage is outside of the user's set parameters, the N.O. contacts open and the red light will flash a code for the particular fault present. The control will also interrogate the line voltage during the fault condition to avoid short cycling and nuisance trips.
