Fixed Parameter
Value
Tolerance Remarks
Tripping Time
200mS
< 10mS
This time starts with the protection
tripping command and is interrupted by
the CB Off Alarm. When this time has
elapsed, a CB defect is present.
Energy Wait Time
200mS
<10mS
During this time the CB's Standby state
is checked before reclosing. This check
can be blocked by applying auxiliary
voltage to terminal 22.
Sync. Wait Time
200mS
< 10mS
During this time the synchronous
condition is checked before reclosing.
This check can be blocked by applying
auxiliary voltage to terminal 23.
Protection Wait
Time
200mS
< 10mS
This time starts with the protection
tripping command after reclosing and is
interrupted by the CB Off Alarm.
C.B. Wait Time
100mS
< 10mS
This time starts with the CB Off Alarm
after an unsuccessful reclosing and is
interrupted by the Off Command. When
this time has elapsed a manual Off is
present.
Relay Test Time
1 s
< 10mS
With a time gap of one second between
each relay, this feature checks the
tripping of each of the output relays.
