1 Preface
The APM303 is a instrumentation and control system for generating sets. It enables a generating set (whether or not it is
connected to an automatic transfer switch) to be started and stopped, and manages the main safety devices for running a
generating set.
Easy navigation between the various screens enables rapid display of all the data recorded (mechanical and electrical values).
There are only three buttons associated with the generating set's PLC, making it easier to operate the generating set.
1.1 Safety/Operating conditions/Powering on


Safety
The
APM303
uses
voltage sources of different origins, which are set to potentials
dangerous to the human body. For this reason, only qualified personnel are authorised
to start up and use the APM303.
Before reading this document, we strongly recommended that you read the safety
instructions relating to starting up a generating set (see General and Safety Instructions).
SDMO Industries shall not be held responsible for failure to observe any of the instructions
described in this manual.
DANGER


Operating conditions
The conditions for use are given at the end of this manual (section ‘Technical specifications’). If a component of the equipment
must be replaced, it is necessary to pay attention to the effects of electrostatic discharges (consult the rules for handling given in
section ‘Handling’).
The APM303 has been factory configured for your application. Any change to the parameters may
alter or render unstable the behaviour of your generating set and the installation.
IMPORTANT


Powering on
Powering on is specific to the electrical equipment within which the APM303 is integrated. It is therefore necessary to consult
the wiring diagram for the equipment provided with this manual, before powering on.
1.2 Integrating the APM303 in its environment
The
APM303
is integrated into central console equipment (type S1500,
S2500, S3500, S4500), fitted on the base frame of the generating set, on
versions II and IV (enclosure).
Figure

integration of the APM303
1.3 Who is this manual intended for?
This manual is intended for users and operators.
The user must be qualified to start the generating set. The user must be capable of monitoring the
generator to ensure it is running correctly, and be able to interpret the electrical and mechanical indications
provided in real time on the different screens. He or she may have to check one or more parameters.
The operator - in addition to having the skills required for users - has the skills required to modify one or
more parameters, to change the operation of an installation. To do this, the operator will have completed
training provided by SDMO Industries beforehand.
Note: for the APM303, no distinction is made between the user and the operator. This means that a user can modify all the internal parameters
(no access code in the APM303).
A self-study training aid is also available on our online Gaïa platform, however SDMO can provide any additional training required.

4 General description of the APM303 module
The APM303 consists of a moulded unit measuring 118 x 108.
Figure 2 - front panel of the APM303
The technical specifications of the APM303 are given in section ‘Technical specifications’.
5 Selecting the operating mode
Two operating modes are available:

Manual mode (
MANU
mode),
Automatic mode (AUTO mode). In all the explanations which follow, the terms
MANU
and
AUTO will be used.
5.1 MANU mode
In this mode, the user has full control of generating set using the 2 START and STOP buttons.
. If a fault is detected (
ALARM!
LED flashing), it is not possible to start up the generating set in
MANU
mode.
. If there is an alarm (ALARM! LED flashing), it is still possible to start up the generating set in MANU mode.
(see section ‘Anomalies’ for fault or alarm management)
Running the generating set
Pressing the START button ( ) automatically launches the starting sequence (preheating () + starter), the RUN LED
flashes ().
When the voltage and speed have stabilised (APM303 internal parameters), the RUN LED becomes fixed.
Manually close the generating set's circuit breaker by switching the control lever on the genset.
The generating set generates or is ready to generate during use ().
Check the electrical and mechanical values on the various screens of the APM303 (see section ‘Display of data’).
() Preheating is not available for all engines.
() If the generating set fails to start after the starting sequence, the RUN LED goes off, the ALARM! LED flashes, and the
"fail to start" fault is recorded in the anomalies stack (see section ‘Events and anomalies, screen 6’ and ‘Fault chart’).
() Users may have to manually close one or more auxiliary circuit breakers.
Stopping the generating set

If possible, to avoid a sudden increase in frequency when manually tripping a circuit breaker, remove the load
progressively, by breaking the terminal circuits one after another.
Manually open the generating set's circuit breaker by switching the control lever on the genset. The load on the
generating set is immediately cut off.
Allow the engine to cool, allowing it to run off load for 3 minutes.
Press the STOP button ( ), the generating set stops immediately, the RUN LED goes off.
Special note on manual mode
When
MANU
mode is selected (
AUTO
LED off), if there is a remote start order (activation of the "remote start/stop"
input, nothing happens, the APM303 remains in MANU mode, but the AUTO LED flashes to signal that there is a remote
order. When the remote order disappears, the AUTO LED goes off.
This standard operation is called "priority MANU mode". It is possible to switch to "priority AUTO mode" (see section ‘"Basic
settings" screen’, parameter B16).

5.2 AUTO mode
In this operating mode, the user does not control the operation of the generating set, the starting and stopping of the generating
set are dependent on the APM303 receiving a remote order.
. If a fault is detected (
ALARM!
LED flashing), it is possible to select
AUTO
mode, but it is not possible to start up the
generating set in manual mode.
. If there is an alarm (ALARM! LED flashing), it is possible to select AUTO mode and start up the generating set in
manual mode.
(see section ‘Anomalies’ for fault or alarm management)
Check that the generating set circuit breaker is closed. Alternatively, switch the circuit breaker control lever.
Press the AUTO button ( ), the AUTO LED lights up, AUTO mode is selected. The generating set is on standby, ready to
start.
Automatic start-up is dependent on activation of the "remote start/stop" input.
This input must be a potential-free contact (), this means that the user must not connect an external power supply to
the terminals provide for this purpose. This will destroy the APM303.
() In general, the external input comes from an automatically controlled ATS.
An automatically controlled ATS independently controls the mains supply (power connection and disconnection), sends the start
order to the generating set and ensures switching in both directions; NormalEmergency and EmergencyNormal.
When the "remote start/stop" input is activated, the RUN LED flashes, the generating set starts immediately (sequence
launch). When the voltage and frequency have stabilised on the alternator terminals, the RUN LED becomes fixed and the
generating set takes over.
When the "remote start/stop" input is deactivated, the RUN LED flashes again, the generating set enters the cooling phase (3
minutes).
Where an ATS is fitted, cooling periods may accumulate. In fact, cooling can also be taken into account in the
changeover switch.
When cooling is complete, the RUN LED goes off and the generating sets stops.
The AUTO LED remains on, the generating set is on standby, ready for another start.
Special note on AUTO mode
When AUTO mode is selected and the generating set is on standby, pressing the START button ( ) immediately
starts the generating set (AUTO mode is deactivated).
Is the generating set is already running, pressing the START button ( ) deactivates AUTO mode operation. The
APM303 switches to MANU mode, the generating set continues to generate.
When the "remote start/stop" input disappears, the generating sets continues to operate as the user has switched to
MANU mode.
When the generating set is operating, pressing the STOP button ( ) deactivates AUTO mode and immediately stops
the generating set, without cooling.
This standard operation is called "priority MANU mode". It is possible to switch to "priority AUTO mode" (see section ‘"Basic
settings" screen’, parameter B16).
In priority AUTO mode, pressing the START ( ) and STOP ( ) buttons does not change the status of the generating set.
5.3 During operation
Monitor the electrical values on screens 4, 5and 6(see section ‘Display of data’), and particularly the current flow.
Never exceed a nominal power indicated on the alternator's rating plate.
Monitor the mechanical values on screens 7and 8(see section ‘Display of data’) and particularly the coolant temperature.
When the generating set is operating (RUN LED lit), in AUTO mode (AUTO LED lit) or in MANU mode (AUTO LED off), the
appearance of an alarm does not modify the operation of the generating set.
(see sections ‘Events and anomalies, screen 6’ and ‘Anomalies’ on alarm management)
When the generating set is operating (RUN LED lit), in AUTO mode (AUTO LED lit) or in MANU mode (AUTO LED off), the
appearance of a fault immediately stops the generating set.
(see sections ‘Events and anomalies, screen 6’ and ‘Anomalies’ on fault management)

7.2.3 Alarm chart
The table below lists all the alarms which can be recorded in the stack.
symbol description
Low battery voltage or charging alternator malfunction: appears when the battery voltage is below the set threshold
after the fixed delay of 3 minutes. This symbol also appears if there is a charging alternator malfunction.
1
Flat battery: if the
APM303
cannot start up the generating set (because the battery voltage is too low), this alarm will
be activated, but the starting sequence is not blocked.
Low fuel level: appears when the daily service tank reaches the low fuel level threshold
E11
and if parameter
E15
is
set to 1 (alarm).
Generating set overload: appears when the output in kW supplied by the alternator exceeds the set threshold
G07
,
after the delay G08.
1
Rotation of alternator phases: may appear on start-up, if an incorrect rotation of phases is detected as a result of the
installation being incorrectly wired.
Alarm input no. x(x=1, 2or 3): appears when the input configured in "alarm x" is active (x takes values 1, 2 or 3).
Generating set maintenance due (non-contractual): appears when the value of parameter
E07
has been reached,
meaning that maintenance is due ().

7.2.4 Appearance of a fault

If the
ALARM!
LED is flashing.
the exclamation mark symbol opposite flashes in
the top right of the screen "1-Main" (figure 14).
The fault is recorded in the stack of events and
anomalies (see section ‘Events and anomalies,
screen 6’).
Figure 14 - appearance of a fault
7.2.5 Clearing a fault
A fault which is active (or present) can be cleared manually by pressing the STOP button ( ). Clearing a fault means that the
user acknowledges the fault. It does not change the fact that the fault remains active and it is not possible to restart the
generating set.
When the fault is cleared, the
ALARM!
LED lights up fixed, the exclamation mark symbol no longer flashes but remains
on the "1-main" screen, the fault remains visible on the "6-events and anomalies" screen.
To make a fault inactive, you must find the root cause behind the appearance of the fault (e.g.: emergency stop triggered).
When the fault becomes inactive, the
ALARM!
LED goes off, the exclamation mark symbol disappears from the "

7.2.6 Fault chart
The table below lists all the faults which can be recorded in the stack.
symbol description
Emergency stop: appears when the user presses the emergency stop button, located on the central console on the
enclosure, or at the entrance to the electrical room.
1
Low fuel level: appears when the daily service tank reaches the low fuel level threshold
E11
and if parameter
E15
is
set to 2 (fault).
Low oil pressure: appears if the engine oil pressure is too low (less than or equal to 1 Bar) or if the binary input is
active.
1
High coolant temperature: appears if the engine coolant temperature is too high (above the activation threshold).
Overspeed: appears if the generating sets the exceeds 120% of nominal speed. The safety feature is set at 150% for 5 seconds on generating set start-up.
Under speed: appears when, after a full start-up, the generating set stops automatically after operating correctly for at
least 5 seconds.
Max. alternator voltage (59): appears when the alternator voltage reaches or exceeds the set threshold (parameter
G01), after a delay of 3 seconds.
Min. alternator voltage (27): appears when the alternator voltage reaches or dips below the set threshold (parameter
G02), after a delay of 3 seconds.
Max. alternator frequency (81H): appears if the alternator's frequency reaches or exceeds the set threshold
(parameter G03), after a delay of 3 seconds.
Min. alternator frequency (81): appears when the alternator frequency reaches or dips below the set threshold
(parameter G04), after a delay of 3 seconds.
Alternator short-circuit (50/51): appears if the current consumed by the alternator reaches or exceeds the set threshold (parameter G05), after the delay G06 which can be adjusted.
Generating set start-up failure: appears if the generating set fails to start up after a full starting sequence.
Generating set shutdown failure: appears after a shutdown request in
AUTO
or
MANUAL
mode, if the speed exceeds
2 rpm, or if the voltage exceeds 10V, or if the oil pressure remains higher than 3Bar, or if the generating set is started
up when no start demand has been given by the APM303. The safety feature is taken into account after fixed delay of
60 seconds.
Fault input no. x(x=1, 2or 3): appears when the input configured in "fault x" is active (x takes values 1, 2 or 3).
Circuit breaker position inconsistent: appears if there is an inconsistency between the motorised command from the
circuit breaker and the position of the circuit breaker (open, closed), after a delay of 5 seconds.
Note: the figures between brackets (which may be accompanied by a letter) are the ANSI codes for the safety features (ANSI = American
National Standards Institute).
