PATH: SETPOINTS ÖØ S3 LOGIC INPUTS ÖØ BLOCK FUNCTIONS
The logic input functions shown above block various operations within the relay. Protection elements will not detect faults,
send messages, or illuminate indicators when blocked, except for the
BLOCK TRIP 1 RELAY setpoint.
A system condition monitor such as Synchrocheck or Closing Spring Charged can be connected to the relay for close
supervision. If BLOCK CLOSE 2 RELAY is selected, this input must be de-asserted to permit operation of the Close Relay.
The
BYPASS SYNCHROCHECK setpoint provides a manual override of the synchrocheck monitor, so an operator can close
the feeder breaker without the programmed synchrocheck condition.
The
BLOCK BRKR STATISTICS setpoint blocks the accumulation of breaker statistical data found on the A3 MAINTENANCE ÖØ
TRIP COUNTERS and A3 MAINTENANCE ÖØ ARCING CURRENT actual values pages. This data includes breaker operation and
trip counters along with breaker arcing current. This input could be used during testing to prevent maintenance operations
from being accumulated.
