Yamaha EF12000DE Owner's Manual page 17

Oil Pressure Monitoring System
The engine is equipped with an oil pressure sensor (of a hydraulic pressure
detection type).
If this sensor detects the oil pressure below the specified level, it stops the
engine automatically. Then, the oil pressure warning lamp flashes for 3 minutes
and goes off.
TIP
I If the engine stalls, check the engine oil level or contamination.
Add or change oil, and restart. (See page 10 for more details.)
Check the fuel level and the fuel cock because the same result can be expect-
ed when the fuel runs out.
I If the engine runs over 4500 r/min for 7 seconds, the engine stops automatical-
ly and the oil pressure warning lamp flashes for 3 minutes.
Automatic bulb checking
When the starter switch is turned to the "START" from the "STOP" position, the
oil pressure warning lamp flashes only once to check the bulb.
If it does not flash, ask a Yamaha dealer to inspect the electrical circuit.
Fail-safe Function of ECU (Electronic Control Unit)
I When the remote control unit is connected, the engine will not start unless
both starter switch on the control panel and the engine switch on the remote
control unit are switched on.
If the engine does not run for 3 seconds when the starter switch is turned to
I
the "START" position on either the generator or the remote control unit, the
starter motor will stop automatically.
If the engine does not start for 21 seconds when the starter switch is turned to
I
the "START" position on either the generator or the remote control unit, the
starter motor will stop automatically.
