It is possible to use Virtual periphery to share the signals between more controllers on the CAN bus. In this
case one controller is a server which physically has the signals connected and other controllers get these
signals via CAN bus.
Priority sw A (Priority switch A) …D …C …
Binary inputs for priority selection.
Priority value
Priority
1 2 34567891011 12 13 1415
Priority sw A 0 or nc 1 0 1010101 0 1 0 1 0 1
Priority sw B 0 or nc 0 1 1001100 1 1 0 0 1 1
Priority sw C 0 or nc 0 0 0111100 0 0 1 1 1 1
Priority sw D 0 or nc 0 0 0000011 1 1 1 1 1 1
Hint:
Priority value is defined by setpoint Priority when all Priority switches are opened or not configured.
The priority value defined by a combination of binary inputs Priority sw X is accepted with 1s delay. So if a
change is made to more inputs simultaneously, it is accepted 1s after the last change sensed.
GroupLink
If the input is configured, the group linking function is active, i.e. this controller becomes the status server for
two groups of gen-sets and informs them about the BTB status.
If this input is closed, the controller reports BTB status as closed, if open, the controller reports open BTB
status.
ManualLdRecon
The rising edge on this input switches the controller to the lower Load Shedding stage when Load
shedding: AutoLd recon = DISABLED and the load is under Load shedding: Ld recon level.
GCB disable
The input blocks the GCB closing, even if all other conditions for its closing are fulfilled. Valid in all modes.
Hint:
If you want to lock out the GCB closing during synchronizing loop test, set Sync/Load ctrl: Phase window =
0. This allows the control loop to be tested while actual GCB closing is blocked.
Conditions for closing:
1) voltage only on generator side of GCB
2) voltage on both sides of GCB and all synchronizing conditions fulfilled.
ReadyToLoad
The output closes when the engine is running, no 2nd level protection is active and the GCB is already closed
or is able to be closed (i.e. all generator parameters are within limits).
ExtValue1reset … ExtValue4reset
Active binary input causes ExtValueX to be reset and held at its default value, given by the setpoint
ExtValueXdeflt.
Hint:
These inputs, if configured, do not block the external set commands (in contrast to ExtValueX up / ExtValueX
down inputs). However, if the reset input is activated, the corresponding ExtValueX is reset to its default
(ExtValueXdeflt) value. This default value is kept in ExtValueX until the reset input is deactivated, and the
external set commands received meanwhile are ignored.
PulseCounter 1
PulseCounter 2
PulseCounter 3
PulseCounter 4
The inputs are linked with corresponding counters, which integrate the pulses sensed at these inputs. Each
rising edge of the signal at input increases the internal counter value.
