6.3 Solving Qc1103™ and Qc2103™ controller alarms
6.3.1 Alarm handling
When an alarm occurs, the unit will automatically go
to the alarm list and display the alarm. The alarm LED
will be flashing.
If reading of the alarms is not desired, use the BACK
push button to exit the alarm list. To enter the alarm
list later, press the RESET HORN push button for 2
seconds to jump directly to the alarm list reading.
The alarm list contains both acknowledged and
unacknowledged alarms, provided that they are still
active (i.e. the alarm condition is still present). Once
an alarm is acknowledged and the condition has
disappeared, the alarm will no longer be displayed in
the alarm list. This means that if there are no alarms,
the alarm list will be empty.
This display example below indicates an
unacknowledged alarm. The display can show only
one alarm at a time. Therefore, all other alarms are
hidden.
To see the other alarms, use the UP and DOWN push
buttons to scroll in the display.
To acknowledge an alarm press the ENTER button.
6.3.2 Fail classes
All the activated alarms of the module are configured
with a fail class. The fail class defines the category of
the alarm and the subsequent action. A fail class can
be selected for each alarm function either via the
display or the PC software.
7 different fail classes can be used:
Engine running:
– Block: Alarm Horn Relay, Alarm Display.
– Warning: Alarm Horn Relay, Alarm Display.
– Trip of GB: Alarm Horn Relay, Alarm Display,
GB Trip.
– Trip & Stop: Alarm Horn Relay, Alarm Display,
GB Trip, Genset cooling down, Genset stop.
– Shutdown: Alarm Horn Relay, Alarm Display,
GB Trip, Genset stop.
– Trip of MB: Alarm Horn Relay, Alarm Display,
MB Trip.
– Trip of MB/GB: Alarm Horn Relay, Alarm
Display, (GB Trip), MB Trip.
Engine stopped:
– Block: Block engine start.
– Warning: -
– Trip of GB: Block engine start, Block GB

– Trip of MB: Block MB sequence.
– Trip of MB/GB: (Block engine start), Block MB

In order to select when the alarms are to be active, a
configurable inhibit setting for each alarm has been
made. The inhibit functionality is only available via
the PARUS software
