RECEPTAClE ANd AC PlUG
These are used for taking AC output power from the generator. A total of two kinds of receptacles, each varying in rated
voltage and current from another, are used. Each model has at least one receptacle to deliver the rated generator output.
The number of AC plugs that can be connected are as many as the receptacles.
The table shows the rated current for each receptacle. Be careful not to use the receptacles and AC plugs beyond the
specified amperage limits to prevent burning.
To connect the appliance to locking receptacle, insert the
plug into the receptacle and turn it clockwise to lock.
dESCRIPTION
The oil sensor mainly functions to detect position of the
surface of engine oil in the crankcase of engines for
general use and to stop the engine automatically when
the oil level goes down below the lower limit specified.
This prevents seizure of engine from occurring due to
insufficient amount of oil in the crankcase.
Since the sensor has been designed to consume a part
of power supplied to the igniter to energize its electronic
circuits, any other external power supply is not necessary
so that it can be mounted at the oil filter port.
Introduction of newly developed sensing principle
features super durability and no change with the passage
of time as it does not use any moving part.
Merits due to introduction of electrical conductivity
detection are as follows:

PRINCIPlE OF SENSING OIl lEVEl
There is a great difference between electric resistance
of the air and that of oil. Since the resistance or air
is higher than that of oil, more electric current passes
through the oil than through the air, although absolute
value of the current is very small. The sensor detects
this current difference and make use of it.
The sensor judges the oil quantity, by comparing a
current flowing across a pair of electrodes (inner and
outer) with the reference, in such a way that if a current
flows between the electrodes more than the reference,
sufficient oil is in the crankcase, on the other hand, if a
current flows less than the reference, oil is not sufficient.
Since an electric current is flown to detect oil quantity,
this is called the “electrical conductivity detection” type
of sensor. The oil level to be detected is determined by
the length of electrodes and their mounting positions
with the engine.
It has resistance to mechanical shocks and property of
no change with the passage of time as sensing element
consist simply of electrodes having no moving parts.
At the same time, it is capable of detecting the oil level
stably as it is not influenced by engine vibrations.
No error occurs due to foam and flow of the oil.
Influence against the ignition system or the electronics
units can be neglected because an electric current
supplied to the sensor can be decreased.
