1. PREFACE
These products provide control and protection in the operation of a generator set. The units allow
starting and stopping of the engine and indicates status and fault conditions. The unit monitors:
Engine temperature
Oil pressure
Fuel level
Charge generator voltage
Engine speed
Alternator output (voltage and frequency)
Alternator current and power
It controls:
Engine fuel supply or engine stopping, via external solenoid
Starter motor via external relay
Automatic generator start and stop
Alarm horn
Preheat (configurable relay feature)
A four-digit, seven-segment display provides extensive monitoring of unit and alternator
parameters, including:
Alternator output voltage and frequency
Engine RPM
Battery voltage
Engine running time
Load current and power
Oil pressure value
Coolant system temperature
Fuel tank level value
Error indication
Program parameters
The unit is extensively programmable through the front panel, with password protection on two
levels. Operational parameters can also be monitored and controlled from a PC via a built-in RS-
232 port.
In the event that the engine fails to start on the first attempt, the attempt will be repeated a
programmed number of times or until successful.
If a fault is detected, the unit shuts down the engine and indicates the failure by flashing a
relevant fault LED.
Remote start / stop and emergency stop inputs provide for remote control of the engine.
Three user defined configurable failure inputs are included that sound an external horn, flash
indicators on the panel and can be programmed to stop the engine.
