8.3 WARNINGS
Warnings are non-critical alarm conditions and do not affect the operation of the generator system, they serve to
draw the operators attention to an undesirable condition.
Example
Alarm 1/1
Charge Failure
Warning
In the event of an alarm the LCD will jump to the alarms page, and scroll through all active warnings and
shutdowns.
By default, warning alarms are self-resetting when the fault condition is removed. However enabling ‘all warnings
are latched’ will cause warning alarms to latch until reset manually. This is enabled using the 8600 series
configuration suite in conjunction with a compatible PC.
Display Reason
CHARGE FAILURE
The auxiliary charge alternator voltage is low as measured from the W/L terminal.
BATTERY UNDER
VOLTAGE
The DC supply has fallen below the low volts setting level for the duration of the
low battery volts timer
BATTERY OVER VOLTAGE
The DC supply has risen above the high volts setting level for the duration of the
high battery volts timer
FAIL TO STOP
The module has detected a condition that indicates that the engine is running
when it has been instructed to stop.
NOTE:- ‘Fail to Stop’ could indicate a faulty oil pressure sensor or switch - If the
engine is at rest check oil sensor wiring and configuration.
FUEL USAGE
Indicates the amount of fuel measured by the fuel level sensor is in excess of the
Fuel Usage alarm settings. This often indicates a fuel leak or potential fuel theft.
AUXILIARY INPUTS
Auxiliary inputs can be user configured and will display the message as written by
the user.
LOW FUEL LEVEL
The level detected by the fuel level sensor is below the low fuel level setting.
CAN ECU ERROR
The engine ECU has detected a warning alarm and has informed the DSE module
of this situation. The exact error is also indicated on the module’s display.
kW OVERLOAD
The measured Total kW is above the setting of the kW overload warning alarm
EARTH FAULT
The measured Earth Fault Current has been in excess of the earth fault trip and
has surpassed the IDMT curve of the Earth Fault alarm.
NEGATIVE PHASE
SEQUENCE
Indicates ‘out of balance’ current loading of the generator.
Sometimes also called Negative Sequence Current or Symmetry Fault
MAINTENANCE DUE
Indicates that the maintenance alarm has triggered. A visit is required by the
Generator service company.
LOADING VOLTAGE NOT
REACHED
Indicates that the generator voltage is not above the configured loading voltage.
The generator will not take load when the alarm is present after the safety timer.
LOADING FREQUENCY
NOT REACHED
Indicates that the generator frequency is not above the configured loading
frequency. The generator will not take load when the alarm is present after the
safety timer.
