6.3 WARNING ALARMS
Warnings are non-critical alarm conditions and do not affect the operation of the engine system, they
serve to draw the operators attention to an undesirable condition.
Example
1/2 Alarms
High Coolant Temperature
Warning
In the event of an alarm the LCD jumps to the alarms page, and scroll through all active alarms.
By default, warning alarms are self-resetting when the fault condition is removed. However enabling
‘all warnings are latched’ causes warning alarms to latch until reset manually. This is enabled using
the DSE Configuration Suite in conjunction with a compatible PC.
If the module is configured for CAN and receives an “error” message from the ECU, ‘CAN ECU
Amber” is shown on the module’s display as a warning alarm.
Fault Description
Analogue Input A to D
The module detects that an input configured to create a fault
condition has become active and the appropriate LCD message is
displayed.
Battery Over Voltage
The DC supply has risen above the high volts pre-set pre-alarm
setting.
Battery Under Voltage
The DC supply has fallen below or risen above the low volts pre-
set pre-alarm setting.
CAN ECU Data Fail
The module is configured for CAN operation and does not detect
data on the engine Can data link.
Charge Alternator Failure
The auxiliary charge alternator voltage is low as measured from
the W/L terminal.
Coolant Temperature Sensor
Fault
The module detects that the circuit to the coolant temperature
sensor has been broken.
Delayed Over Current
The measured current has risen above the configured trip level for
a configured duration.
Digital Inputs A to F
The module detects that a digital input which has been user
configured to create a fault condition has become active and the
appropriate LCD message is displayed.
ECU Amber
The module detects that the engine ECU has detected a fault
causing an Amber alarm.
ECU After Treatment
The module detects that the engine ECU has detected that the
after treatment is currently in progress.
ECU Malfunction
The module detects that the engine ECU has detected a fault
causing a Malfunction alarm.
ECU Protect
The module detects that the engine ECU has detected a fault
causing a Protect alarm.
ECU Red
The module detects that the engine ECU has detected a fault
causing a Red alarm.
ECU Water In Fuel
The module detects that the engine ECU has detected that there is
water in the fuel.
Expansion Unit Failure
The module detects the DSE Net link to the expansion module has
failed or communications to the expansion module has been lost.
