Stopping
1. The return delay timer operates to ensure that the
starting request has been permanently removed
and is not just a short term removal.
Should another start request be made during the
cooling down period, the set will return on load.
2. If there are no starting requests at the end of the
return delay timer, the load is removed from the
generator set to the mains supply (Qc2111™ only)
and the cooling timer is initiated.
The cooling timer allows the set to run off load
and cool sufficiently before being stopped. This is
particularly important where turbo chargers are
fitted to the engine.
3. After the cooling timer has expired, the set is
stopped.

Manual mode
Activate Manual mode by pressing the START push
button. An LED indicator beside the button confirms
this action.
Manual mode allows the operator to start and stop the
set manually.
If the engine is running off-load in Manual/Start
mode and a remote start signal becomes present, the
module will automatically instruct the changeover
device to place the generator set on load (‘Close
Generator’ and ‘Delayed Load Output 1, 2, 3 & 4’
becomes active (if used)). Upon removal of the
Remote Start Signal, the generator set remains on
load until Stop/Reset mode or Auto mode are
selected.
NOTE: If a digital input configured to panel lock is
active, changing module modes will not be possible.
Viewing the instruments and event logs is NOT
affected by panel lock.
Starting sequence
When in manual mode, the set will not start
automatically.
1. To begin the starting sequence, press the START
button.
• If ‘protected start’ is disabled, the start
sequence begins immediately.
• If ‘Protected Start’ is enabled, the Waiting in
Manual mode icon is displayed and the LED
above the START button flashes. The START
button must be pressed once more to begin the
start sequence.
2. The fuel relay is energised and the engine is
cranked.
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 is made. Should this sequence continue
beyond the set number of attempts, the start
sequence will be terminated and the display shows
‘Fail to Start’.
3. When the engine fires, the starter motor is
disengaged. Speed detection is factory configured
to be derived from the main alternator output
frequency.
Additionally, rising oil pressure can be used to
disconnect the starter motor (but it cannot detect
underspeed or overspeed).
4. After the starter motor has disengaged, the Safety
On timer activates, allowing Oil Pressure, High
Engine Temperature, Under-speed, Charge Fail
and any delayed Auxiliary fault input to stabilise
without triggering the fault.
