current rating of the Generator.
Before starting the Genset main circuit breakers in OFF
position.
Warning
The main circuit breaker has to be always in ON posi-
tion.
Before running the generator set, make sure that all cir-
cuit breakers are set to off position. if the CBs are not
set to off passion ,engine stalling or alternator winding
insulation of formation or burning can occur.(for Ma-
nuel Generator Sets)
7. STARTING UP THE GENERATOR SET
7.1. Starting the Generator in Manuel Mode
Warning
Before starting the Generator , cut all connection with
electrical devices (for Manuel Gensets)
Manual Start
1. Set the main circuit breaker to OFF position.
2. Crank the engine by turning the key switch on the
control panel ,after engine is started stop cranking.
3. Warm up the generator (run the Generator 3 or
5 minutes)
4. Check the voltage ,if the voltage is 400 V between
phases ,between phase and neutral 230 V
5. Connect the loads you want to use in socket on the
control panel.
6. Set the main circuit breaker to ON position in order
to load the Gen.Set.
7.2. Auto Start
Press the Auto button on the control panel , every-
thing will be automatic in this position.
Warning;
! Cranking the engine for a long time, will cause the low
battery power and even burn up the starter.
! Check the fuel level, if you run the engine while there
is no sufficient fuel in the fuel that will cause air in the
fuel.
! Battery; if you use maintenance type battery, Check
electrolyte level every month. if electrolyte level is low
, add distilled water until the high level. If electrolyte
level is too low, battery won’t work properly, and en-
gine won’t start, on the other hand, if the electrolyte
level is too high it will erodes the surrounding parts.
Always keep the electrolyte level between high and
low level.
7.3. Checks after starting up the generator
1. Check for any abnormal noise or vibration on the
generator set.
2. Engine is running rough or hard.
If you noticed one of them ,stop the engine and try to
find out the problem or contact to a service.
Warning
• While the generator is running , exhaust manifold
and silencer will be too hot, don’t touch it.
• Never fill the fuel tank while generator is running.
7.4 Loading
1. Make sure that Genset is running at rated frequency.
2. After setting the outlet circuit breaker on position,
check the voltage on the control panel, if the voltage
is 400 V ±5% (50Hz)between phases or 230 V ±5%
(50Hz) between phase and neutral then you can load
the Genset.
3. Set the load circuit breakers on the distribution
panel to ON position one by one .if the application is
wrong, engine speed will decrease and then eventually
engine will stop. Before all this happens, cut the load
from the Genset and set the main circuit breaker to
OFF position and do the necessary checks.
4. Balance three phase during operation. Stop the en-
gine for check if the tolerances exceed 20 % .Be sure
to keep the tolerance among three phase less than
20%.
5. The load for each phase must below the rated load
as well as the current must less than rated current.
6. Concerning the starting three phases asynchronous
motors, first start the heavy duty motors, and then
start the light duty motors.
7. An overload will trip the circuit breaker. if this hap-
pens , reduce the electrical load on the circuit, wait a
few minutes before starting the generator.
7.5. Stopping the generator set
Stopping the Generator in Manual mode.
1. Set the main circuit breaker to OFF position. Take
the load off from generator.
2. Run the generator for 3 minutes without load, don’t
stop the generator suddenly, generator could be dam-
aged.
3. Set the key switch off position.
