CMG Series
The CMG Series is a self powered Current Monitor/Relay that is used
to detect the presence of AC current. When the monitored current
exceeds the trip point for longer than 400 mSec., the internal relay
energizes (Pick-up). When the monitored current drops below the trip
point for longer than 50 mSec., the internal relay de-energizes (Drop-
out). No physical connection is required as the line to be monitored is
magnetically coupled by passing the conductor through the protrud-
ing Current Transformer of the monitor. No external supply is needed
to power the monitor.
\\\^OPERATION
The current trip point specified is with one turn through the transformer.
Each time the number of turns through the transformer doubles, the trip
point effectively halves. Example: CMG-0100-20 will trip at 20 amps with
one turn passing through the transformer. By placing two turns through the
transformer, the relay will trip at 10 amps. Likewise, four turns will cause the
relay to trip at 5 amps. (See below)
