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 synchronism check 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
single-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.

Switch (SXCBR/SXSWI)

tStartMove is the supervision time for the apparatus to start moving after a command
execution. When the time has expired, the switch function 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 switch function 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).
