4.7 Fuel Filling
The fuel filling point is located externally on the side of
the and right hand side of the generator (Fig 4.7).
The fuel level sender is located internally on the base of
the generator set and sends the level to the control
module on the output panel.
Before refuelling turn off the unit allow cooling for a few
minutes and refuel.
Wipe up any spilt fuel and dispose of in a safe manner
as laid out in your company’s HSE procedures.
Consideration should be given to using proprietary fuel
treatments particularly if the fuel contains a high bio
-
diesel concentration and is to be left in the tank for
many months. Introduce the additive in accordance with
the manufacturer’s instructions. Add it through the
normal fuel points and mix thoroughly. Run the engine
for 15 minutes to allow for treated fuel to be pulled
through the filters, pump and injectors.
Connect the equipment to be powered (load) into the
socket outlets on the generator control panel.
Operating the generator at low load levels for long
periods of time may cause excessive smoking, reduce
efficiency due to carbon build
-
up and cause other engine
problems
Do not overload the generator as this will cause
overheating, and shorten the life of the generator. Check
that the total load from all equipment connected does not
exceed the generator rating.
Each output socket is individually protected by an MCB
(miniature circuit breaker), 15 Amps on small output
sockets and 30 and 63 Amps on the larger sockets. If
the current being drawn through the socket exceeds this
for a short time the MCB will trip. To reset the MCB when
it has tripped remove the load from that socket, wait a
few minutes and then reset.
Operating the generator at low load levels for long
periods of time may cause excessive smoking, reduce
efficiency due to carbon build
-
up and cause other engine
problems.
4.6 Shutdown Protection Devices
The generator is fitted with the following protection
devices that will shut down the generator in the event of
a fault. They are indicated by LED’s on the engine
control module (Fig 4.1a).
Start Fail.
Operates if the engine fails to start after 3
attempts. This is to help prevent damage to the starter
motor. If the engine fails to start then the cause should
be investigated before further attempts are made.
Low Oil Pressure.
This operates if the oil pressure falls
below a safe level. This can be caused by a lack of oil,
wrong type of oil or high temperature. Check and top up
the oil level as necessary. During starting, the alarm is
held off for 10 seconds to allow the oil pressure to build
up to normal running level. The engine will not crank if
there is no low oil pressure signal prior to starting.
The low fuel shut down also causes the low oil pressure
circuit to trip and the low
-
oil neon will also light.
Low Fuel Level.
The fuel gauge also incorporates a low
fuel shutdown facility. The set will shut down when the
level falls to approximately 10
-
12% of its capacity, thus
eliminating the need to bleed the system at restart.
