Section 1 Introduction
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,
Charging Alternator
Alternator output (voltage and frequency).
It controls:
●
●
●
●
●
Engine fuel supply or engine stopping, via external solenoid
Starter motor, via external relay.
Alarm horn
Preheating (configurable relay feature)
Load transfer (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
Elapsed time
Error indication
Program parameters
The unit is extensively programmable, with password protection on two levels.
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 an
appropriate fault LED.
Remote fuel, start and emergency stop inputs provide for remote control of the engine.
Three user-defined inputs are included that sound an external horn, flash indicators on the panel
and can be programmed to stop the engine.
Two extra outputs can be configured to act on an alarm, when the engine is running, when a
load can be transferred to the alternator, or when engine preheating is required.
The operational parameters of the unit can be monitored and controlled from a PC via a built-in
RS-232 port.
