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).
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.
The default length is set to 200 ms for a circuit breaker (SXCBR).
