Switch controller (SCSWI)

The parameter
default for control of circuit breakers, disconnectors and earthing switches the control model
is set to
When the operation shall be performed in one step, and no monitoring of the result of the
command is desired, the model direct control with normal security is used.
At control with enhanced security there is an additional supervision of the status value by the
control object, which means that each command sequence must be terminated by a
termination command.
The parameter
indication, that is, at
value of the position. At
bad or intermediate state.
tSelect is the maximum allowed time between the select and the execute command signal,
that is, the time the operator has to perform the command execution after the selection of the
object to operate. When the time has expired, the selected output signal is set to false and a
cause-code is given.
The time parameter
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 synchrocheck 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
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
which means no start of the synchronizing function is done, and when
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
operate, Sel & Op phase, or only at operate, Op phase.
Application manual
RemoteIncStation has only effect on the IEC61850-8-1
The parameter
communication. Further, when using IEC61850 edition 1 communication, the
parameter should be set to
IEC61850-8-1 edition 1.
CtlModel specifies the type of control model according to IEC 61850. The
SBO Enh (Select-Before-Operate) with enhanced security.
PosDependent gives permission to operate depending on the position
Always permitted it is always permitted to operate independent of the
Not perm at 00/11 it is not permitted to operate if the position is in
tResResponse is the allowed time from reservation request to the
tSynchronizing supervises that the signal synchronizing in progress is obtained in
InterlockCheck decides if interlock check should be done at both select and
Yes , since the command LocSta is not defined in
