When the engine oil pressure drops during operation, the oil pressure monitor lamp
will flash, and the automatic shutoff will be engaged.
When this occurs, check the engine oil level, and replenish to the maximum level if
needed.
<Caution>
The engine oil pressure monitor cannot detect the degradation of engine oil itself.
Please check the engine oil periodically, and change if needed.
(Refer to 11. Checking and Maintenance )
Check the fuse next, when the abnormality, other than WATER TEMP, BATTERY
CHARGED OR OIL PRESSURE is detected. If the fuse is burned out, consult
with our authorized distributor or our engineering section, because there may be
an abnormality of electric/electronic parts or wiring and repairing may be required.
(4) Overheat Monitor Lamp
OVERHEAT monitor lamp may flash in the case the machine is used excessively
over the duty cycle or over load.
When the OVERHEAT monitor lamp is blinking, this equipment cuts the out put off.
When this overheat occurs, there may be a possibility of overloading. Always use
the equipment within the rated duty cycle and output power.
<Caution>
There may be a case that the lamp will not flash, depending on the welding type
or the weather condition.
5-8. Earth Leakage Circuit Breaker and Grounding
Danger : Electric Shock
Ground every grounding terminal to the earth as set out in the manual.
If even one of all is unconnected by mistake or accident, it will be much more
dangerous for human body than the NO RELAY case, because leaking current
inevitably goes through the body.
Even though all the terminals of the loads have been grounded to the earth, the
bonnet (canopy) grounding terminal should be grounded to the earth.
Grounding should be made after the engine is stopped.
Whenever the earth leakage relay has activated, always repair the leaking
circuit first.
The equipment is provided with the earth leakage relay in the Circuit Breaker to
detect any leakage arisen due to the troubles as insulation failure of the load while
the generator is running. And cutting off the circuit for protection against any
accident such as electrical shock resulting from the trouble.
The specifications of the earth leakage relay:
Rated Sensitive Current: 30mA (or below)
(Grounding resistance: 500 Ω or below)
(1) Grounding Work
The qualified electrician should perform the
grounding work of the following 2 points
(500 Ω or below).
The Outer Bonnet of this equipment (bonnet grounding terminal)
The Outer Bonnet of the load
<Caution>
In the event you cannot ground the generator to the earth, consult with the
authorized distributor or service dealers.
