Leaks at hose connections must be immediately repaired, especially the raw water impeller pump. It is certainly
possible that the raw water impeller pump will produce leaks, depending upon the situation. (This can be caused
by sand particles in the raw water etc.) In this case, immediately exchange the pump, because the dripping water
will
be sprayed by the belt pulley into the sound insulated casing and can quickly cause corrosion.
6. Check all electrical lead terminal contacts are firm.
This is especially the case with the temperature switch contacts, which automatically switch off the generator in
case of faults. There is only safety if these systems are regularly checked, and these systems will protect the
generator, when there is a fault.
7. Check the motor and generator mounting screws are tight.
The mounting screws must be checked regularly to ensure the generator is safe. A visual check of these screws
must be made, when the oil level is checked.
8. Switch the land electricity/generator switch to zero before starting or switch off all the load. (only Marine)
The generator should only be started when all the load have been switched off. The excitation of the generator
will be suppressed, if the generator is switched off with load connected, left for a while, or switched on with extra
load, thus reducing the residual magnetism necessary for excitation of the generator to a minimum. In certain
circumstances, this can lead to the generator being re-excitated by means of a DC source. If the generator does
not excitate itself when starting, then excitation by means of DC must be carried out again.
9. Check the automatic controls functions and oil pressure.
Removing a cable end from the monitoring switch carries out this control test. The generator should then
automatically switch off. Please adhere to the inspection timetable (see Checklist in the appendix).
8.3.4 Starting the generator
1. Open sea lock and close battery switch if necessary.
2. Push „ON/OFF“ button to switch panel on.
3. Push „Start/Stop“ button to start the generator.
4. Switch on load.
Attention!:
In the event of starting problems, close the sea water
inlet cock. Panda marine generators only.
Should there be any reason to turn the engine (over) or start
the engine i.e. to bleed the fuel system, the sea water inlet
cock must be closed! During the starting process, the cooling
water pump is driven with the motor. The cooling water is
discharged to the exhaust outlet and, since the motor has not
run, the exhaust pressure is not high enough to expel the sea
water which has been brought to the exhaust outlet. To avoid
filling the exhaust outlet with water and causing further
problems, close the inlet sea water valve.
Once the engine is running, be sure to open the inlet valve!
8.3.5 Stopping the generator
1. Switch off load.
2. If the load is higher than 70 % of the nominal load, the generator temperatures should be stabilised by switching
off the load for at least 5 minutes.
At higher ambient temperatures (more than 25 °C) the generator should always run for at least 5 minutes without
load, before it is switched off, regardless of the load.
