1.Introduction
6
The EAOM-19 provides for automatic transfer of a load from mains to generator in the event of a
mains failure. The unit is able to detect failure of any phase of the mains and to start and switch
over to a generator if the mains voltage goes outside pre-set limits. Both automatic and manual
control is possible. A test mode is also available which allows the generator to be run without
taking the load. The unit monitors generator operation and gives warning of any faults that are
detected. It monitors:
Mains voltage
Engine speed
Battery voltage
Engine temperature
Oil pressure
It controls:
Engine fuel supply or engine stopping, (via external solenoid)
Starter motor, (via external relay)
Automatic generator start and load transfer on mains failure, (via external mains and
generator contactors)
Alarm horn
A four-digit, seven-segment display provides extensive monitoring of unit and generator
parameters, including:
Mains voltages
Alternator voltage and frequency
Battery voltage
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 a relevant fault LED. Two user configurable inputs are included that sound an
external horn, flash indicators on the panel and can be programmed to stop the engine,
disconnect the load or the remote inhibit.
