With the switch setting depicted above the relay will go through the following operations.
1. Once the breaker has tripped and the Protection trip contact has closed the A/R in
progress LED will flash and the A/R contact will close. The relay will wait for the setting of
Dead Time 1 to expire, it will then issue a reclose output pulse, the counter will increment
one count and the A/R in progress LED will become steady.

before removing the Block Instantaneous Protection contact and LED and driving to
