6.4.3 ENGINE RUNNING
Once the engine is running, the Warm Up timer, if selected, begins, allowing the engine to stabilise before accepting
the load.
DSE7210/DSE7310 - The generator will be placed on load.
DSE7220/DSE7320 - Load will be transferred from the mains supply to the generator
NOTE:-The load transfer signal remains inactive until the Oil Pressure has risen. This prevents
excessive wear on the engine.
As the load increases and decreases, the DSE7300 series module (not available on DSE7200 series) may
(depending upon configuration) add dummy loads or remove non-essential loads. This is configured as part of the
Load Shedding and Dummy Load control settings in the DSE Configuration Suite Software.
See section entitled Dummy Load / Load Shedding elsewhere in this document for further details.
If all start requests are removed, the stopping sequence will begin.
6.4.4 STOPPING SEQUENCE
The return delay timer operates to ensure that the starting request has been permanently removed and isn’t just a
short term removal. Should another start request be made during the cooling down period, the set will return on
load.
If there are no starting requests at the end of the return delay timer, the load is transferred back from the generator
to the mains supply and the cooling timer is initiated.
The cooling timer allows the set to run off load and cool sufficiently before being stopped. This is particularly
important where turbo chargers are fitted to the engine.
After the cooling timer has expired, the set is stopped.
