The Autoreclose function must be enabled in the CONFIGURATION 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 On Pulse (use AR Off Pulse to bring it out of service)

programming a function key on the HMI.

if applicable, using IEC 60870-5-103 communications

Further validation signals are also required to switch on Autoreclose. These are the DDB signals AR Enable CB1

and AR Enable CB2. 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.
