Analog Faults, Fault Inputs Name Action Signal

Analog Faults	Eight analog fault inputs are user programmable for 12 fault conditions. Each analog fault input requires a specific analog
	signal type.

Low Engine Temperature	An analog DC signal is provided from an engine mounted sender. The low engine temperature fault is activated when engine
	temperature is below a pre-determined setpoint for a specified time delay. This fault is programmable for temperature
	setpoint level, transient time delay settings and other functions.

High Engine Temperature #1 An analog DC signal is provided from an engine mounted sender. The high engine temperature fault is activated when engine temperature is above a pre-determined setpoint for a specified time delay. This fault is programmable for the level of temperature setpoint, transient time delay settings and other functions.

High Engine Temperature # 2 An analog DC signal is provided from an engine mounted sender. The high engine temperature fault is activated when the engine temperature rises above a pre-determined setpoint for a specified time delay. This fault is programmable for the level of temperature setpoint, transient time delay settings and other functions.

Low Oil Pressure #1	An analog DC signal is provided from an engine mounted sender. The low oil pressure alarm fault is activated when the oil
	pressure is below a pre-determined setpoint for a specified time delay. This fault is programmable for pressure setpoint level,
	transient time delay settings and other functions.
Low Oil Pressure #2	An analog DC signal is provided from an engine mounted sender. The low oil pressure shutdown fault is activated when the
	oil pressure is below a pre-determined setpoint for a specified time delay. This fault is programmable for pressure setpoint
	level, transient time delay settings and other functions.
Low Battery Voltage	The low battery voltage alarm fault is activated when the battery voltage drops below a pre-determined setpoint for a
	specified time delay. This fault is programmable for the voltage setpoint level, transient time delay settings and other
	functions.
High Battery Voltage	The high battery voltage alarm fault is activated when the battery voltage rises above a pre-determined setpoint for a
	specified time delay. This fault is programmable for voltage setpoint level, transient time delay settings and other functions.
Weak Battery	The weak battery alarm fault is activated when the battery voltage drops below a pre-determined setpoint for a specified
	time delay. The weak battery alarm detects a low capacity (i.e. “weak“) battery condition during the cranking cycle. The weak
	battery alarm is programmed for a lower battery voltage setpoint and shorter time delay than the low battery alarm function.
	This fault is programmable for voltage setpoint level, transient time delay settings and other functions.
Undervoltage	All 3-phases of the generator output are monitored for an undervoltage condition. The undervoltage sensor is programmable
	for type of fault action (alarm or shutdown), pickup and dropout voltage setpoints (i.e. adjustable hysteresis) and transient
	time delay settings.
Under frequency	The generator output is monitored for an under frequency condition. The under frequency sensor is programmable for type of
	fault action (alarm or shutdown), frequency setpoint, and transient time delay settings.
Engine Speed Analog Input	A magnetic pickup (engine speed sensor) measures engine speed. The engine speed sensor allows the controller to perform
	the following control functions:
	Overspeed shutdown
	Crank Disconnect control
	Loss of speed signal detection
	Starter Re-engage control
	RPM display
