Input Type/Preset Description
Discrete input [DI
05] Programmable
Preconfigured to "External
acknowledgment"
This discrete input is used as a remote acknowledgment
for alarms. The input is normally de-energized. When an
alarm is to be acknowledged the input is energized. The
first time an alarm in acknowledged, the centralized
alarm/horn is silenced. When the input is energized a
second time, all alarms, which are no longer active, will
be acknowledged.
This discrete input is configured as a Control input in the
alarm class and is not delayed by the engine speed.
Discrete input [DI
06] Programmable
Preconfigured to "Release MCB"
Only applicable for application mode
A04
This discrete input is configured as a Control input in the
alarm class and is not delayed by the engine speed.
• Energized •
The MCB is enabled and closure of the breaker is
permitted.
• De-energized •
The MCB is not enabled and closure of the breaker is
not permitted. This function permits a supervisory
control (i.e. a PLC) to allow the closure of the MCB by
the genset control.
Discrete input [DI
07] Fixed to "MCB open reply" Only applicable for application mode
A04
This input implements negative function logic.
The controller utilizes the CB auxiliary (B) contacts into
this discrete input to reflect the state of the MCB.
This discrete input must be energized to show when the
breaker is open and de-energized to show when the MCB
is closed. The status of the MCB is displayed on the
screen.
This input is usually used in all breaker modes to change
between frequency/voltage and power/power factor
control (refer to note below).
Discrete input [DI
08] Fixed to "GCB open reply"
Only applicable for application modes
A03
and
A04
This input implements negative function logic.
The controller utilizes the CB auxiliary (B) contacts into
this discrete input to reflect the state of the GCB. This
discrete input must be energized to show when the
breaker is open and de-energized to show when the GCB
is closed. The status of the GCB is displayed on the
screen.
This input is usually used in all breaker modes to enable
reverse power protection, overload MOP protection,
mains decoupling and the activation of the load sharing
(refer to note below).
Discrete input [DI
09] Programmable
"Discrete Input 9
Can be set-up with description, delay, operation, alarm
class, self acknowledgment, and enable.
