Automatic shutdown operating conditions
If the conditions listed below continues for more than ten seconds while starting, or two seconds while the
engine is being operated, the engine will shutdown.
If the water temperature exceeds 110 °C (230 °F) ± 3°C (5 °F)
If the oil pressure falls below 0,3 kgf / cm² (4.27 lbf / in² top cover option) or 1,0 kgf / cm² (14.22 lbf / in² oil rail
option).
Cautions:
l There is no automatic shutdown for low water levels.
l Diode capacity: current 3 amps, reverse voltage 600V, this is mandatory.
Notes:
l Maximum current draw for the standard oil pressure switch is 0.42 amps (5 Watts maximum bulb).
l A delay fuse can be fitted if necessary.
