5.4.2 STARTING SEQUENCE
NOTE: There is no Start Delay in this mode of operation.
The fuel relay is energised, and the engine is cranked.
NOTE: With the 3110-xxx-02 CAN variant, compatible ECU’s receive the start command
via CAN and transmit the engine speed to the DSE controller.
If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the
Crank Rest duration after which the next start attempt is made. If this sequence continues beyond the
set number of attempts, the start sequence is terminated, and the display shows Fail to Start .
The starter motor is disengaged when the engine fires. Speed detection is factory configured to be
derived from the AC alternator output frequency but can additionally be measured from a Magnetic
Pickup mounted on the flywheel or from the CAN link to the engine ECU depending on module
variant.
Additionally, rising oil pressure can be used disconnect the starter motor (but cannot detect under
speed or over speed).
After the starter motor has disengaged, the Safety On Delay timer activates, allowing Low Oil
Pressure, High Engine Temperature, Underspeed and any delayed User Configured digital inputs to
stabilise without triggering the fault.
5.4.3 ENGINE RUNNING
NOTE: For further details of module configuration, refer to DSE Publication: 057-087
DSE3110 DSE Configuration Suite PC Software Manual.
Once the engine is running and all starting timers have expired, the animated Engine Running icon
is displayed.
Once the generator is available, it is then placed on load (Close Gen output becomes active (if used)).
Once the generator has been placed on load, it is not automatically removed. To manually remove the
load either:
• Press the Auto Mode button to return to automatic mode. The set observes all
Auto Mode start requests and stopping timers before beginning the Auto Mode Stopping
Sequence.
• Press the Stop/Reset Mode button to remove load and stop the generator.
