Control Functions

Switch Function

1. Main Switch: Manage DC circuit and shutdown.
   Tip: Press the main switch to the “OFF” position to prevent the battery from running out when not in use more than 7 days.

2. ECO Switch: When turned to the ON position, the engine will sense the load needed and run at a slower RPM to save fuel.

3. AC RESET: When overloaded, the reset breaker will trip. The engine will continue to run, but there will be no output from the inverter. Unplug the devices and reduce the load. Push in the reset button to reset.

4. Start Button: Press in this button, the engine can start or stop.

Oil indicator (red)
When the oil in the crankcase drops below safety line, oil protection system will automatically shut down the engine, and oil alarm indicator lights up; the engine can be restarted up only after the oil is filled to oil level.

Tip: In the case of flame-out of the engine or being unable to be started up, pull startup handle. If oil indicator flashes a few seconds, the oil volume is insufficient, fill oil and restart.

Overload indicator (red)
When the overload indicator lights up, the generator has detected that the output of connected electrical equipment has been overloaded, causing frequency converter to be overheated or AC voltage to rise. At this moment, AC protector works and stops generating to protect the generator and connected electrical equipment.Power indicator (green) is off and overload indicator (red) lights up, but the engine will not stop running.

When overload indicator is on and the generator has no output, take the following counter measures:

1. Switch off electrical equipment connected, and shut down the generator.
2. Reduce total power of electrical equipment connected to the range of rated output.
3. Check whether there is any foreign matter blocking in cooling air inlet, and whether there is any abnormality in related control components. If there is any problem, eliminate it immediately.
4. After checking, restart the engine.
   Tip: When using electrical equipment with high starting current (such as compressors, submersible pump, etc. ), the overload indicator may start to light up  for a few seconds at the beginning, but this is not the failure mentioned earlier.

Power indicator (green)
The Power indicator lights when the engine is started and output normally.

DC protection
When electronic equipment connected to DC of the generator is running, if current is beyond overload current, DC protection automatically cuts out to”OFF” position. To operate the DC output again, press DC protection to “ON” position.

1. “ON” DC outputs normally.
2. “OFF” DC does not output.

ATTENTION
If DC protection is in off status, reduce the load of electronic device connected to rated output range of the generator and press it to ON position. If it is still back to OFF status, stop using electrical equipment directly and consult your dealer.

Energy-saving switch(ECO SWITCH)

1. “ON”
   When energy-saving switch is set to “ON” position, the device controls engine speed based on the load connected, thus very good fuel consumption and low noise can be obtained.

2. “OFF”
   When the energy-saving switch is set to the “OFF” position, the engine will run at rated speed, regardless of whether being connected to a load.

Tip: When using inductive appliances such as air compressor and submersible pump etc, the energy-saving switch must be in “OFF” position, because it requires great startup current.
