This consumption is fed from the generator’s battery,
it is essential to connect a 230 V power input
otherwise the battery would be discharged within a
few hours.
This connection comes from the 230 V inverter
output and connects to the “input power 230 V” on
the generator’s control panel. This also gives power
to the battery and charger located in the generator
control panel, that is active; if the battery of the
generator has low charge it will be recharged through
this energy.
Note: Not feeding the 230 V power input means the
battery will go flat within a few hours. This could lead
to further damage to the cells making it an unusable
battery.
Operation startup by remote contacts: the generator
consists of two normal open contacts. While the
inverter/charger keep the 2 contacts open, the
generator is off, as the figure below:
When the inverter/charger command the generator
startup, two contacts will join and the generator will
initiate the start up process. The generator keeps
running, while the contacts are joined.
When the contact splits again the generator will stop
and remain at rest until a next start.
STEP 3.
Understanding the Generator’s Startup & Stop
Process
1. The startup of the generator will begin a few
seconds after the outage of the power supply.
2. The system sends a signal to the choke closing
the air passage.
3. The system gives power to the starting motor
to start up the engine. If engine starts, the
power to the starting motor will immediately
stop to avoid any gear damage to the starting
motor.
The maximum working time of the starting motor
is 5 seconds. If the engine has not started after 5
seconds, the stating motor will be disconnected to
prevent overheating. If the engine has not started
after the first attempt, a second attempt can be
performed after a few seconds, repeat process for a
maximum 5 attempts. If the generator does not start
automatically during the 5 attempts, the SIGNAL
lamp will blink, showing start failure and generator
pass to stop.
The engine has a temperature sensor, if the engine
is hot after recent operation, the choke signal will be
annulled.
NOTE: If you perform continuous auto start attempts
for I or 2 minutes it may cause malfunctions to the
temperature sensor. This may indicate that the tem-
perature levels will annul the choke even though the
engine temperature is not at the correct temperature
for a startup without choke assistance.
NOTE: In low temperature conditions, below 50 C
the engine will have much greater difficulty to start
