Operation of the generating set

Before starting 

 

Caution! : 

Before starting, ensure that the seacock 

is open as the seawater pump rotor can be damaged if 

run dry for just a few seconds. 

Generating sets with a 

Keel Cooling system are not fitted with a seawater 

pump.

Never  use  a  starting  aerosol  or  any  other  equivalent 

product. These products are highly flammable.
Before starting the engine and before the set is used 

each time:

• Check the fuel level
• Open the fuel shutoff valve
• Open the seacock (if fitted)
• Check the engine oil level and fill with the recom-

mended  oil  if  necessary.  See  the  “Maintenance”

section for more information.

• Check  the  coolant  level  and  fill  with  the  recom-

mended  coolant  if  necessary.  See  the  “Mainte-

nance” section for more information.

• Open the hold space panel(s) to fully ventilate the

hold space if it is not equipped with a fan. Otherwise

run the fan in the hold space for 5 minutes.

• Close  the  battery  switch  (ON  position)  and  check

that the emergency stop is not activated.

 

Caution! : 

Ensure you have replaced the protection 

elements before starting the generating set.

Notice: 

If your engine  has not been  used for several 

months of if the fuel circuit has been drained, use the 

priming pump situated above the fuel filter. This fills the 

fuel circuit if it has drained out or after a circuit compo-

nent has been replaced. 

Starting the generating set

I

 

Caution! : On a soundproof generating set

, the lo-

cal/remote selector must be in 

remote

 position to start 

the generating set using the instrument panel. 
Carry out the following operations to start your generat-

ing set in complete safety:

1. Press the ON/STOP button. All of the indicators

illuminate  and  an  audible  signal  sounds.  This  stage 

allows  you  to  check  that  these  elements  are  working 

properly. After a few moments, only the oil and battery 

charge indicators will remain lit.

2. Hold  the  START  button  at  midcourse  to  begin

preheating.  The  PREHEAT  warning  light  illuminates. 

Hold  the  button  for  5  to  20  seconds  according  to  the 

temperature  on  the  outside.  Push  fully  the  button  to 

start the generating set.

 

Caution! : 

If  the  generating  set  does  not  start  on 

the first attempt, repeat the manoeuvre, waiting 5 to 15 

seconds between each attempt, with the set switched 

off. Never force it as there is a risk of water backflow 

into the engine via the exhaust system.
Check the indicators on the instrument panel after start-

ing and when operating the set. 
Check also that the seawater is running through the ex-

haust and check there are no fuel or water leaks.

 

Caution! : 

If the coolant temperature rises or the oil 

pressure falls abnormally, the corresponding indicators 

will illuminate and 

the generating set will stop auto-

matically. 

Identify  and  eliminate  the  cause  before  restarting  the 

engine. See the “Fault-finding” section for more infor-

mation.
