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.
StartButton
Binary input has the same function as Start button on the controller front panel. It is only active in MAN mode
and when setpoint

->
Local Button
is set to EXTBUTTONS or BOTH.
StopButton
Binary input has the same function as Stop button on the controller front panel. It is only active in MAN mode
and when setpoint

is set to EXTBUTTONS or BOTH.
FaultResButton
Binary input has the same function as Fault reset button on the controller front panel.
To enable this function, set the setpoint
Basic settings
->
Local Button
to EXTBUTTONS or BOTH.
HornResButton
Binary input has the same function as Horn reset button on the controller front panel.
GCBButton
Binary input has the same function as GCB button on the controller front panel. It is active in MAN and
TEST modes only. In TEST mode in some special cases only (see description of the TEST mode in chapter
Mode and functions description).
Hint:
All Binary inputs, which simulate controller front panel buttons, are edge (no level) sensitive, and they react
on the rising edge only. Minimal input pulse duration is 0,2 seconds.
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 (e.g. during synchronizing) for its closing are
fulfilled. Valid in all modes.
Hint:
If you want to lock out the GCB (or MCB) closing during synchronizing loop test, set
Sync/Load ctrl:
Phase
window
= 0. This allows the control loop to be tested while actual GCB (or MCB) closing is blocked.
Conditions for closing:
1) voltage only on generator side of GCB (or MCB)
2) voltage on both sides of GCB (or MCB) and all synchronizing conditions fulfilled.
Alt brightness
Active binary input switches controller display backlight to the alternative setting. Alternative intensity of the
backlight can be set independently using the controller panel buttons.
Hint:
Input available in IG-NT/EE and modifications only. For IG-Display and IS-Display modules, this binary input
is located in the Power connector and it’s function is fixed (not configurable).
