1.3 WARNINGS

Warnings are used to warn the operator of an impending fault

BATTERY CHARGE FAILURE, if the module does not detect a voltage from the warning light

terminal on the auxiliary charge alternator, the

depending on the configuration of Nominal DC Voltage).

Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant icon will be illuminated

when the input is active

Shutdowns are latching and stop the Generator. The alarm must be cleared, and the fault removed

to reset the module. In the event of a shutdown the appropriate icon will be illuminated

NOTE:- The alarm condition must be rectified before a reset will take place. If the

alarm condition remains it will not be possible to reset the unit (The exception to this is the

Low Oil Pressure alarm and similar 'delayed alarms', as the oil pressure will be low with

the engine at rest). Any subsequent warnings or shutdowns that occur will be displayed

steady, therefore only the first-up shutdown will appear flashing.

NOTE:- The safety on time (used for delayed alarms) is pre set to 12 seconds and can

not be changed.

FAIL TO START, if the engine does not fire after the pre-set 3 attempts at starting, a shutdown will

be initiated.

The

icon will illuminate.

LOW OIL PRESSURE, if the module detects that the engine oil pressure has fallen below the low

oil pressure switch after the Safety On timer has expired, a shutdown will occur.

The

icon will illuminate.

HIGH ENGINE TEMPERATURE if the module detects that the engine coolant temperature has

exceeded the high engine temperature switch after the Safety On timer has expired, a shutdown

will occur.

The

icon will illuminate.

OVERSPEED, if the engine speed exceeds the pre-set trip (14% above the nominal frequency) a

shutdown is initiated. Overspeed is not delayed, it is an immediate shutdown.

The

icon will illuminate.

NOTE:- During the start-up sequence the overspeed trip level is extended to 24%

above the normal frequency for the duration of the saftey timer to allow an extra trip level

margin. This is used to prevent nuisance tripping on start-up.

UNDERSPEED, if the engine speed falls below the pre-set trip (20% of the nominal frequency)

after the Safety On timer has expired, a shutdown is initiated.

The

icon will illuminate.

Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant icon will be illuminated

when the input is active
