4.11.8 Alarms and Warnings
In the event of abnormal operating conditions the unit will issue a warning or an alarm and shut the engine
down as required. The LCD shows an appropriate message indicating the nature of the condition. To draw
operator attention to the condition the flashing general alarm LED is used.
Alarms will generally shut the engine down. Warnings are given for less severe situations which by
themselves will not damage the engine but may cause future malfunctions.
In general, alarms are not self-resetting. They are reset by pressing the stop button or the alarm button
once the engine has stopped.
The following alarm icons are displayed
Speed Icon
For an over or under speed warning the speed icon flashes quickly. The alarm LED
flashes and an appropriate message is displayed on the LCD.
For over and under speed alarms, the speed icon is lit. The alarm LED flashes and the
engine is shutdown. An appropriate alarm message is displayed on the LCD.
If the engine is about to start and is currently in the start delay period then the speed
icon flashes slowly. Similarly if the engine is running in cool down and about to stop,
the speed icon flashes slowly
Low Oil Pressure Icon
The low oil pressure icon flashes red as a warning if oil pressure is below the low oil
pressure warning set point while the engine is running. The engine remains running.
The icon is supplemented with an LCD message.
If the oil pressure is below the shutdown set point, the icon is lit and alarm LED
flashes. The engine is shutdown. The icon and alarm are supplemented by an LCD
message.
If the oil check before cranking is enabled, and the check indicates oil pressure may
be present, the icon LED flashes slowly.
If the oil sender goes open circuit, the icon flashes and the alarm icon is lit. The icon
and alarm are supplemented by an LCD message.
High Engine Temperature Icon
The high engine temperature icon flashes red as a warning if the temperature being
measured is above the temperature warning set point while the engine is running. The
engine remains running. The icon is supplemented with an LCD message.
If the temperature goes above the shutdown set point, the icon is lit and alarm LED
flashes. The engine is shutdown. The icon and alarm LED are supplemented by an
LCD message.
If the temperature sender fails, then the icon flashes and the alarm icon is lit. The icon
and alarm are supplemented by an LCD message.
Battery Warning Icon
Battery charging problems do not shut the engine down. Indications are warnings
only.
The battery warning icon flashes slowly if the battery voltage is below the low battery
set point while the unit is in READY or standby. This usually indicates the battery
needs charging or the external charger has failed.
If the battery-charging alternator fails to excite during engine running the icon LED is
solid red.
If the battery fails to reach the charging voltage during running the icon LED flashes
slowly. This usually indicates a failed battery or failed alternator. In each of these
cases the LCD displays appropriate warning messages.
