Warning: Beware of the high voltages connected to this unit.
Indicators on the central section of the panel will flash if a fault is detected. If a fault is indicated,
proceed as follows:

Find and fix the fault.
Press the Reset button to enable a restart.
Press the Engine Start button

In addition to the indicators on the centre panel, the Alarm LED will flash in the event of a fault. To
discover the fault being reported by the Alarm LED, press repeatedly until the Alarm option has
been selected. The display will indicate the fault condition, as follows:

1.
2.
3.

This LED flashes if the engine has not started after the programmed Number of Starting Attempts
(P26). The unit must be reset, by pressing the Failure Reset (6) button, before a fresh attempt can
be made.

This LED flashes if the thermostatic switch on the engine indicates high temperature. If this fault
occurs, the

will stop the engine without any Engine Cooling Time (P34).

EAOM-72F

This LED flashes if the Oil Pressure Switch on the engine indicates low oil pressure while the
engine is running. To obtain this indication, the engine must have been running for at least the
period specified by the Oil Pressure Bypass Time (P28). If this fault occurs, the

will

stop the engine without any Engine Cooling Period (P34).

EAOM-72F

This LED flashes and the horn sounds if the output from the battery charge generator fails after
the engine has started. The fault will not be indicated if it occurs within the period defined by the
Control On Delay (P31) after the engine has started. This failure will not shut down the engine.

This LED flashes if the alternator speed goes outside the values defined by the Speed Lower
Limit (P02) and Speed Higher Limit (P03) parameters. For a fault to be indicated, the speed must
be outside these limits for longer than the period defined by the Speed Fault Control Delay
parameter (P33). Alternator speed is measured either by measuring alternator output frequency
or by monitoring an external magnetic pick-up as selected by program parameter Speed Sensing
Input Selection (P16). This failure immediately stops the generating set without Engine Cooling
Time (P34).

9. FAULT FINDING

9.1 Fault indications

9.1.1 Failed to Start LED

9.1.2 High Temperature LED

9.1.3 Low Oil Pressure LED

9.1.4 Charge Generator Failure LED

9.1.5 Over Speed LED

This LED flashes if the alternator output fails to reach the value specified by the Alternator Voltage
Lower Limit parameter (P00) within the period defined by the Control on Delay parameter (P31).
This failure immediately stops the generating set without Engine Cooling Time (P34).

9.1.6 Generator Voltage Failure LED

Spare inputs 1, 2 and 3. These inputs function as per the programming of parameters
Configurable Failure Input-1, 2, 3 (P36, P37, P38). The LEDs will indicate the status of the
input lines and the course of action is determined by the programming.

9.1.7 Spare-1, 2, 3
