circuit. No other binary input can be used for this purpose.

Breaker control and Trip command operation

Relay supports breaker control operation. The control operation can be done from
control push-buttons provided on relay front, from remote via MODBUS
communication or from signals wired to relay binary inputs duly configured for
control operation.

Trip Circuit Supervision

Application
The Trip Circuit Supervision TCS detects faults in the electrical trip / open control
circuit (which includes trip coil, trip contact, wiring and auxiliary voltage) of
circuit. It can supervise trip circuit in breaker open as well as breaker close
condition.
It is possible to enable/disable TCS functionality through configuration parameter.
For the TCS functionality the BI2 need to be connected in parallel to the trip output
BO2 as shown in the figure below. Additional the BI2 need to be configured for the
TCS functionally.
