EDR-3000
IM02602003E
Single Contact Indication – 52b only
If only the
52b signal is used for the monitoring of the “OPEN command”, the switch command will start the moving
timer. The Position Indication will indicate an INTERMEDIATE position. If the moving time elapsed before the
switchgear has reached the OPEN position, the switching operation was not successful and the Position Indication will
change to Pos DISTURB.
A CLOSE command also starts the moving time. Because the device does not receive a close signal by the breaker, it
assumes that the breaker is in close position after the moving time has elapsed.
The following table shows how breaker positions are validated based on 52b only:
