The time parameter tResResponse is the allowed time from reservation request to the
feedback reservation granted from all bays involved in the reservation function. When
the time has expired, the control function is reset, and a cause-code is given.
tSynchrocheck is the allowed time for the
synchronism check function to fulfill the
close conditions. When the time has expired, the function tries to start the
synchronizing 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.

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
