function. If
tSynchrocheck
is set to
0
, no synchrocheck is done, before starting the
synchronizing function.
The timer
tSynchronizing
supervises that the signal synchronizing in progress is
obtained in SCSWI after start of the synchronizing function. The start signal for the
synchronizing is set if the synchrocheck conditions are not fulfilled. When the time
has expired, the control function is reset, and a cause-code is given. If no
synchronizing function is included, the time is set to
0
, which means no start of the
synchronizing function is done, and when
tSynchrocheck
has expired, the control
function is reset and a cause-code is given.
tExecutionFB
is the maximum time between the execute command signal and the
command termination. When the time has expired, the control function is reset and
a cause-code is given.
tPoleDiscord
is the allowed time to have discrepancy between the poles at control
of three one-phase breakers. At discrepancy an output signal is activated to be used
for trip or alarm, and during a command, the control function is reset, and a cause-
code is given.
SuppressMidPos
when
On
suppresses the mid-position during the time
tIntermediate
of the connected switches.
The parameter
InterlockCheck
decides if interlock check should be done at both
select and operate, Sel & Op phase, or only at operate, Op phase.

tStartMove
is the supervision time for the apparatus to start moving after a
command execution is done from the SCSWI function. When the time has expired,
the command supervision is reset, and a cause-code is given.
During the
tIntermediate
time, the position indication is allowed to be in an
intermediate (00) state. When the time has expired, the command supervision is
reset, and a cause-code is given. The indication of the mid-position at SCSWI is
suppressed during this time period when the position changes from open to close or
vice-versa if the parameter
SuppressMidPos
is set to
On
in the SCSWI function.
If the parameter
AdaptivePulse
is set to
Adaptive
the command output pulse resets
when a new correct end position is reached. If the parameter is set to
Not adaptive
the command output pulse remains active until the timer
tOpenPulsetClosePulse
has elapsed.
tOpenPulse
is the output pulse length for an open command. If
AdaptivePulse
is set
to
Adaptive
, it is the maximum length of the output pulse for an open command.
The default length is set to 200 ms for a circuit breaker (SXCBR) and 500 ms for a
disconnector (SXSWI).
tClosePulse
is the output pulse length for a close command. If
AdaptivePulse
is set
to
Adaptive
, it is the maximum length of the output pulse for an open command.
