Circuit Breaker Monitoring And Control Menu - DEMA CPM 310 G User Manual

Circuit Breaker Monitoring and Control Menu

Circuit Breaker Monitoring and Control Menu is
represented as "Breaker" on the main screen and is
accessed by S1 button, as shown on the picture to the
left.
Circuit Breaker Monitoring and Control Menu displays
the position of the circuit breaker as "OFF" or "ON" and
enables the user to control the circuit breaker remotely.
The position of the circuit breaker is displayed as "OFF"
or "ON", and additionally on a mimic diagram, as
shown on the picture at the bottom. On this diagram,
the CB position is displayed both as text (OFF) and
mimic diagram.
The S1 (OPEN) and S2 (CLOSE) buttons are used for
controlling the circuit breaker remotely. As shown on
the pictures, the physical OPEN button is colored red
and CLOSE button is colored green.
Two topics must be paid attention to ensure the
correct operation of the Circuit Breaker
Monitoring and Control Menu!
1. The relay must get the circuit breaker position
information correctly to display it correctly. In order to
achieve that, a normally open contact of the circuit
breaker should be wired to one of the programmable
inputs of the relay, and this input should be
programmed as "CB Position". The procedure is
described in detail at the dedicated section.
2. To control the circuit breaker remotely over CPM 310
G, the trip output of the relay should be wired to the
CB trip / release coil terminals, and the CB closing
output of the relay should be wired to the CB closing
coil terminals. See the dedicated section of this manual
for the output programming information. □
