4.16 DEADTIME ENABLED
This is an optional interlock in the dead time logic. This signal has to be high to allow the dead time to run. If this
signal goes low, the dead time stops and r
esets, but stays primed, and will restart from zero when it goes high
again. A typical PSL mapping is from the CB Healthy input or from selected signals from the System Check logic. It
could also be mapped to an opto-input to provide a 'hold off' function for the follower CB in a 'master/follower'
application with 2 CBs. If this optional interlock is not required, DeadTime Enabled can be left unmapped, and it
will default to a high state.
4.17 AR INIT TRIPTEST (INITIATE TRIP TEST)
If AR Init TripTest is mapped to an opto-input
, and that input is activated momentarily, the IED generates a CB trip
output via AR Trip Test. The default PSL then maps this to output to the trip output relay and initiates an
Autoreclose cycle.
4.18 AR SKIP SHOT 1
If AR Skip Shot 1 is mapped to an opto-input, and that input is activated momentarily, the IED logic will cause the
Autor
eclose sequence counter to increment by 1. This will decrease the available number of reclose shots and will
lockout the re-closer.
4.19 INH RECLAIM TIME (INHIBIT RECLAIM TIME)
If Inh R
eclaim Time is mapped to an opto-input, and that input is active at the start of the reclaim time, the IED
logic will cause the r
eclaim timers to be blocked.
