st
Trip
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 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, and 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 is still closed after the reclose pulse, the Block Instantaneous
Protection contact will open, the LED will extinguish and the relay will go directly to Lockout.
3. If the Protection Trip Contact has opened the relay will wait for the Reclaim Time to expire
before removing the Block Instantaneous Protection contact and LED and driving to
Lockout.
4. The Lockout indication and contact has to be reset from the front panel of the relay.
