4. PRELIMINARY CHECKS:
- Make sure these operations are carried out with the generator placed on a horizontal and stable surface.
- Oil is the most important element influencing the efficiency and life of the engine, the engine manual gives details of the type of oil to
use and the correct oil level for this generator.
ATTENTION: Running the engine with insufficient oil could cause serious damage.
- Check the fuel level: use only clean and water-free fuel (it is better to use lead-free petrol or petrol with a low lead content, in order to
minimize the deposits in the combustion chamber).
ATTENTION: Fuel is highly inflammable and explosive under certain conditions.
Refuel in a well ventilated area with the engine switched off, do not smoke or approach the equipment with an open flame.
Do not overfill the tank (do not fill up to the cap), because vibration could cause fuel spillage.
Avoid spilling fuel while filling the tank. Ensure that the cap is correctly screwed down after filling. If fuel has been spilt,
ensure that the area is completely dry before starting the engine.
Avoid any skin contact with the fuel and do not inhale the vapour. It is important to keep the fuel in a place inaccessible to
children. The fuel fumes are highly inflammable.
- Check the air filter: make sure that it is in good condition and free from dust and dirt. To locate the filter consult the engine manual.
ATTENTION: do not use the generator without the air filter: the life of the engine and the generator will be reduced!
- Activate the battery: fill the compartments to their maximum level with a 30/40% sulphuric acid solution and wait at least two hours
before using.
ATTENTION: do not touch the acid and do not smoke or use naked lights: battery fumes are highly inflammable. Keep the
acid out of reach of children.
5. STARTING THE GENERATOR:
- Ensure that no appliance is plugged into the generator.
- For generators with electric starters turn the key to the “START” position and release it as the machine starts.
- To start the recoil operated generators, turn choke to on position, pull the cord handle until resistance is felt, then pull energetically.
ATTENTION: Do not allow the recoil handle to rewind quickly, feed back manually to avoid damage to the starter.
When the engine has warmed up, turn off the choke, the generator is now ready for use. –
- For Yanmar diesel engines refer to label located on rear of tank for starting procedure.
NOTE: If the generator is used at high altitudes or temperatures, the air-fuel mix ratio may be too rich; this will cause higher
consumption and lower performance. Check the effective power of the generator by means of the following correction factors:
HEIGHT: Power diminishes on average by 1% for every 100 m of height above sea level;
TEMPERATURE: Power diminishes on average by 2% for every 5 degrees centigrade of temperature above 20 degrees centigrade. If
the generator is used above an altitude of 2000 m, consult the manufacturer for advice on the fuel mix for best performance.
6. USING THE GENERATOR:
NOTE: The generator is built to current standards and has been designed to satisfy a very wide range of applications.
It should be remembered that every application is subject to specific electrical, accident prevention and environmental standards; for
this reason the generator should be considered as an integral part of the complete installation, which should be designed, tested and
approved by qualified technicians and/or companies.
- Cables plugs, sockets and cable couplers should be suitable for the environmental conditions. Cables should be preferably flexible,
and contain a metallic screen. Plugs and sockets should conform to BS4343. If metallic screen cable is not available, a cable with high
abraison resistance, with a separate protective conductor should be utilised. Cables should be as short as practicable, and routed to
avoid possible accidental damage. All cables, plugs, sockets and connectors should be inspected regularly.
- Industrial and hand-held tools(110v) and domestic portable electrical equipment(220v) should preferably of Class II construction.
- NEVER overload sockets ! Maximum outputs are :-
110v – 16amp Socket 2KW, 32amp Socket 4 KW : 220v – 16amp Socket 4KW, 32amp Socket 8KW.
- In order to avoid electrical accidents, all connections to the distribution panel must be carried out by qualified technicians. Incorrect
connections can harm people and damage the generator.
Protection against electric shock: all generators rely on their electrical insulation, however, on request, they can be supplied with
various additional protection options e.g. earth leakage breaker, insulation monitor (isometer), or they can be protected in the same
way during installation by the user.
It is important therefore, to follow the instructions as below:
1) Standard generator: protected by electrical insulation. This equipment has a thermal protection device and/or a thermomagnetic
device to protect against a current surge, overload or short-circuit. This is known as a ‘floating’ system.
In this case the generator winding must not be earthed using the terminal "PE" or with any other part of the generator.
2) Generator with optional switchboard (or with other devices installed by the user): must be protected using a circuit breaker' which
automatically cuts off the power supply.
This has thermal overload protection devices and/or thermomagnetic combinations with earth-leakage circuit breakers or insulation
monitors (isometer), which automatically cut off the power supply in the event of a breakdown of the insulation. When fitted with an
earth leakage breaker the unit must be earthed using the PE terminal. If an isometer is fitted this connection is NOT required.
IMPORTANT: In the event of the user installing earth-leakage circuit-breakers, it is important for its correct functioning that:
A) For single phase generators the neutral of the output must be connected to earth. B) For three phase generators the
neutral (star point) should be connected to earth.
In the case of a three phase delta connection, it is not possible to install an earth-leakage circuit-breaker.
Contact our technical office for further information if required.
-
The generator is provided with a PE connection screw to ensure that the unit can be earthed as shown by the label, which also
ensures that all metal parts of the generator are simultaneously earthed.
- CTE (Centre Tapped to Earth) generators should be earthed at all times.
- Do not connect accessories with unknown electrical specifications to the generator.
- The electrical circuit of the generator is protected by a switch, which is either thermomagnetic, earth-leakage-thermomagnetic or
thermal, an overload or a short circuit will cut off the flow of current.
To reset, disconnect all appliances, check the cause of the short-circuit or overload and switch back on.
- If using the generator as a battery charger, place the battery at least 1 m from the unit, making sure that the filling plugs are removed
from the cells.
- Take care to observe the battery polarities, incorrect connection of positive and negative poles could cause the battery to explode.
