Double Shot, Auto Reset, Live Line In, Block Instantaneous OFF
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 providing the line
voltage is zero, the Block Instantaneous contact will pick up and the front panel LED will be lit,
the A/R in progress LED will flash and the A/R contact will close, if the line voltage is not zero
the relay will wait in the reset state until it is, it will then wait for the setting of Dead Time 1 to
expire, then issue a reclose output pulse, the counter will increment one count and the A/R in
progress LED will become steady.
2. If the Protection Trip Contact and Circuit Breaker aux have both reset the relay will wait for the
Reclaim time to expire then reset ready for the next operation.
3. If the after the Reclose Pulse the Protection Trip Contact and Circuit Breaker are still
tripped the relay will wait for Dead Time 2 to expire then issue another Reclose Pulse, the
counter will increment one count. If after the second pulse the Protection Trip Contact
and Circuit Breaker has reset the relay will reset ready for the next operation.
4. If after the second pulse the Protection Trip Contact is still closed the relay will drive
directly to Lockout.
5. If the Protection Trip Contact has reset but the Circuit Breaker has not the relay will wait
for the Reclaim time to expire before driving to Lockout.
6. The Lockout indication and contact has to be reset from the front panel of the relay.
