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.
12.3.9.3 Switch (SXCBR/SXSWI)
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. The default length is set to 200 ms for a
circuit breaker (SXCBR) and 500 ms for a disconnector (SXSWI).
