Operate logic
The OPERATE output of this module can be used for closing the circuit breaker if it
is opened for an unknown reason. The OPERATE output is activated immediately
after the CB_POSOPEN input becomes active and CB_POSCLOSE inactive. The
pulse length for the OPERATE output signal can be set with the Operate pulse time
setting.
The module is disabled if the signal power supply is faulty
(SI_PWR_ON = FALSE) or the open command is sent to the
breaker (CB_OPEN_CMD = TRUE).
5.7.5 Application
The uncorresponding circuit breaker position means that the actual position of the
circuit breaker’s control switch is unmatched with the real position of the circuit
breaker. In a normal situation, the function is used in cooperation with the
autoreclose function (DARREC). The operate signal can start the autoreclosing
when detecting that the circuit breaker has opened in an unknown situation. If the
function is used as a stand-alone function when an unknown circuit breaker open is
detected, the function output can be used as an information indication for the
supervision station.
