Section 10
Control
The reset timer defines a time from the issue of the reclosing command, after which the reclosing
sequence resets. Should a new trip occur during this time, it is treated as a continuation of the
first fault. The reset timer is started when the CB closing command is given.
A number of outputs for Autoreclosing state control keeps track of the actual state in the
reclosing sequence.
