Circuit Monitor Device
The RAW-1 and the CM are panel mounted relays containing a series LED for visual indication and blocking diodes for prevention of alarm indication when the breaker is opened. If a trip coil or auxiliary trip relay coil opens, the LED goes out and the relay is deenergized. The relay itself is self-monitoring since opening of any of the series components causes the same conditions as the loss of the trip coil. On breaker opening, the RAW-1 is energized through the breaker "B" contact. The time delay auxiliary relay does not time out.
