SYNCHRONISATION CHECK

Where the check synchronism function is set, this can be enabled to supervise manual circuit breaker Close
commands. A circuit breaker Close command will only be issued if the Check Synchronisation criteria are satisfied.
A time delay can be set with the setting Sys Check time. If the Check Synchronisation criteria are not satisfied
within the time period following a Close command the device will lockout and alarm.
7.8

CB HEALTHY CHECK

A CB Healthy check is available if required. This facility accepts an input to one of the opto-inputs to indicate that
the breaker is capable of closing (e.g. that it is fully charged). A time delay can be set with the setting CB Healthy
Time. If the CB does not indicate a healthy condition within the time period following a Close command, the device
will lockout and alarm.
