abbreviations used:
GS = Generating Set
ATS = Automatic Transfer Switch
1 - Safety instructions

Read the safety instructions on starting up
a GS.
(see General and Safety Manual)

When the GS is off, the control unit may be powered by a
dangerous voltage (preheating, battery charger).
When on, the APM303 is powered by a dangerous voltage.
The APM303
has been factory preconfigured; modifying its
parameters may make the generating set unstable.
2 - Powering on
Close the battery isolator (if fitted),
Turn the switch on the front of the central console ON (if fitted).
3 - Checks before starting

Battery voltage,
Engine oil level,
Coolant level,
GS circuit breaker open.
If the ALARM! LED is flashing, refer to section 7.
4 - Front panel, buttons and LEDs
STOP button
stops the GS and
acknowledges the fault (if
ALARM!
is flashing)

AUTO button
selects AUTO or MANUAL
mode
START button
starts the GS
other buttons
access to screens
(see section 13)
ALARM!
no anomaly (alarm or fault)
fault detected but cleared
anomaly detected (alarm or fault)
AUTO
MANUAL mode by default
AUTO mode selected
remote start/stop
on/engine cooling
RUN
GS stopped
GS started (
MANUAL
mode)
start or stop in progress
5 - Operation in MANUAL mode: GS on
MANUAL mode inhibits AUTO mode.
If the ALARM! LED is off (no fault present), it is possible to
start the GS.
Press the START button, the RUN LED flashes, the GS starts.
When the voltage and frequency have stabilised, the RUN LED
becomes fixed.

Manually close the GS circuit breaker; the GS takes load
or is ready to take load.
Check the electrical and mechanical values on the APM303
screens (see section 13).
5 - Operation in MANUAL mode: GS off

Manually open the GS circuit breaker (the power is cut
off).
Allow the engine to cool down for 3 minutes.
Press the STOP button, the RUN
LED goes off, the engine
stops.
6 - Operation in AUTO mode
The AUTO mode is active only if the AUTO LED is fixed.
Check that the GS circuit breaker is closed.
Press the AUTO button, the AUTO LED lights up, AUTO mode
is selected.
Start up is possible if the ALARM! LED is off.
Start-up is launched on activation of the remote start/stop,
input, which must be a () potential-free contact (no AC or DC
voltage).
() e.g. coming from a self-regulating ATS.
On activation of the input, the RUN LED flashes and the GS
starts.
When the voltage and frequency have stabilised, the RUN
LED becomes fixed and the GS takes over.
On deactivation of the remote start/stop input, the RUN LED
flashes.
After a cooling period (3 minutes) (), the GS stops and the
RUN LED goes off.
The AUTO
LED remains on, the GS is on standby, ready for
another start.
(
) If an ATS is fitted, the total number of cooling periods
must be correctly adjusted.
MANUAL mode takes priority over active AUTO mode:
- pressing the START button activates MANUAL mode,
- pressing the STOP button stops the GS.
7 - Appearance of an anomaly

If the ALARM! LED flashes (see section 13), this means that
an anomaly (alarm or fault) has been detected.
alarm = GS not stopped
fault = GS stopped
To view the anomaly, press or
to show the screen
below:
A
The anomaly appears with an order number
B
Pictogram symbolising the anomaly (see sections 9 and
11)
C
Anomaly status (fault only, see section 10)
D
Number of hours GS has been operating when anomaly
appeared
E
See section 13 when flashes
Note: this screen also shows the events (see section 12).
8 - Active and inactive alarm

inactive

An alarm cannot be cleared: it becomes inactive even after
intervention from the user.
