5.4 AUTORECLOSE ENABLE
The Autoreclose function must be enabled in the C
ONFIGURATION column before it can be brought into service. It
can be brought into service by:
● using an opto-input mapped to the AR Enable DDB signal
● pulsing the DDB signal AR Pulse On (use AR Pulse Off to bring it out of service)
● programming a function key on the HMI.
● if applicable, using IEC 60870-5-103 communications
A further validation signal is also required to switch on Autoreclose. This is the DDB signals AR Enable CB. Once
Autoreclose is in service, the AR In Service DDB signal is asserted and the AR Status cell in the CB CONTROL
column is set accordingly.

● Three-phase (AR 3P)
● Single-phase and Three-phase (AR 1/3P)
● Controlled by commands from DDB signals that must be mapped to opto-isolated inputs in the PSL (AR
