7.3 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 DSE Configuration Suite in conjunction with a compatible PC.
Display Reason
AUXILIARY INPUTS If an auxiliary input has been configured as a warning the appropriate
LCD message will be displayed and the
COMMON ALARM LED will
illuminate.
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.
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.
