Protections and faults

Shutdown

Stops the set, latches, and blocks restarting until it is reset.

Warning

Advisory. It shows on the screen and clears itself when the condition goes away.

Shutdowns

Fault	Trips at	Code
LOW OIL PRESSURE	Below 20 psi	SPN 100 FMI 1
HIGH COOLANT TEMP	Above 107 °C	SPN 110 FMI 0
ENGINE OVERSPEED	Above 2124 rpm (118%)	SPN 190 FMI 0
UNDERFREQUENCY	Below 57 Hz for 10 s on load	SPN 190 FMI 18
GENERATOR OVERLOAD	Above 110% for 10 s	OVERLOAD
FUEL LEVEL EMPTY	Tank empty	SPN 96 FMI 1
FAIL TO START	Three failed crank attempts	OVERCRANK
EMERGENCY STOP	The button	SPN 970 FMI 31

The codes are the real J1939 SPN/FMI numbers an engine ECM would log, so they are worth showing on screen as-is.

Warnings

Warning	When
Low oil pressure	Below 30 psi
High coolant	Above 102 °C
Low fuel	Below 10%
Low battery	Below 24 V
Overload	Load over 100%
NOT IN AUTO	Whenever the switch sits in STOP

Resetting

Set Stoped = true.

The reset is refused while the condition is still present (a hot engine, an empty tank, the e-stop still pressed in) and the Output window says why. Fix the cause first.

Built-in allowances

Low oil pressure is ignored for the first 10 seconds

Real oil pressure takes a moment to build after the engine catches. Without that grace period, every start would trip.

Fuel exhaustion is off by default

The set ships with infinite fuel. See Configuration to turn real consumption back on.
