Frequency difference limit between bus and line for synchrocheck
Phase angle difference limit between bus and line for synchrocheck
Voltage difference limit between bus and line for synchronizing and
synchrocheck
Time delay output for synchrocheck when angle difference between
bus and line jumps from "PhaseDiff" + 2 degrees to "PhaseDiff" - 2
degrees
Frequency difference minimum limit for synchronizing
Frequency difference maximum limit for synchronizing
Breaker closing pulse duration
tMaxSynch, which resets synchronizing function if no close has been
made before set time
Minimum time to accept synchronizing conditions
Voltage high limit for energizing check
Reset ratio, voltage high limit
Voltage low limit for energizing check
Reset ratio, voltage low limit
Maximum voltage for energizing
Time delay for energizing check when voltage jumps from 0 to 90%

Operate time for synchrocheck function when angle difference
between bus and line jumps from "PhaseDiff" + 2 degrees to
"PhaseDiff" - 2 degrees
Operate time for energizing function when voltage jumps from 0 to
90% of Urated
