3. When the engine has stopped, it is possible to send
configuration files to the module from Qc
Configuration Suite PC software and to enter the
Front Panel Editor to change parameters.
4. Any latched alarm that has been cleared will be
reset when STOP mode is entered.
When the engine is running and the module is put into
Stop/Reset mode, the module will automatically
instruct the generator set to unload (‘Close Generator’
and ‘Delayed Load Output 1, 2, 3 & 4’ become
inactive (if used)). The fuel supply de-energises and
the engine comes to a standstill. Should any form of
remote start signal be present while operating in this
mode, a start will not occur.
4.2.2.2
Auto mode / Mains failure
On generator sets equipped with a Qc2111™
controller, this mode of operation is used to ensure
continuity of supply to critical loads during a mains
failure condition. This is the normal mode of
operation when installed on a stand-by generator set.
Activate Auto mode by pressing the AUTO push
button. An LED indicator beside the button confirms
this action. The Auto Mode icon appears on the
display to indicate Auto Mode operations if no alarms
are present.
Auto mode will allow the generator set to operate
fully automatically, starting and stopping as required
with no user intervention.
Starting
1. If a starting request is made, the starting sequence
will begin.
Starting requests can be from the following
sources:
• Mains supply out of limits (Qc2111™ only).
• Activation of an auxiliary input that has been
configured to remote start.
• Activation of the inbuilt exercise scheduler.
2. To allow for ‘false’ start requests, the start delay
timer begins.
Should all start requests be removed during the
start delay timer, the unit will return to a stand-by
state.
3. If a start request is still present at the end of the
start delay timer, the fuel relay is energised and
the engine will be cranked.
NOTE:
If the unit has been configured for CAN,
compatible ECU’s receive the start command via
CAN and transmit the engine speed to the
Qc1111™/Qc2111™ controller.
4. If the engine fails to fire during this cranking
attempt, the starter motor is disengaged for the
crank rest duration after which the next start
attempt begins. Should this sequence continue
beyond the set number of attempts, the start
sequence will be terminated and the display shows
‘Fail to Start’.
Engine running
1. Once the engine is running and all starting timers
have expired, the animated Engine Running icon
will be displayed.
2. The generator set is placed on load if configured
to do so.
NOTE:
The load transfer signal remains inactive until the
Oil Pressure has risen. This prevents excessive
wear on the engine.
3. If all start requests are removed, the stopping
sequence will begin.
