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
