D-500L Firmware V-5.8
K35D03-EN - 61 -
The RUN mode is entered by pressing the
button.
When the RUN mode is selected, the engine will be started regardless of the mains availability.
The starting sequence is as described below:
The unit turns on the fuel and preheat glow plugs (if any) and waits for preheat timer.
The engine will be cranked for programmed times during crank timer. When the engine fires, the
crank relay will be immediately deactivated. See section
Crank Cutting
for more details.
The engine will run at idle speed during Idle Speed Timer.
The engine will run unloaded until another mode is selected..
The RUN mode allows also manual contactor control through MC
and GC
buttons.
When a contactor button is pressed, the related contactor will change position. Thus if it was on, then it
will turn off. If it was off then it will turn on.
If the other contactor was on, then it will turn off, the controller will wait for the related contactor timer and
the contactor will turn on. This will prevent manual closure of both contactors.
In order to stop the engine press
button or select another mode of operation.
The TEST mode is entered by pressing the
button.
The TEST mode is used in order to test the genset under load.
Once this mode is selected, the engine will run as described in the AUTO mode, regardless of the mains
availability and the load will be transferred to the genset.
The genset will feed the load indefinitely unless another mode is selected.
13.5. TEST MODE
If Emergency Backup mode is enabled and if the mains are
off, then the mains contactor will be deactivated and the
generator contactor will be activated.
When the mains are on again, a reverse changeover to the
mains will be performed, but the engine will keep running
unless another mode is selected.
If uninterrupted transfers are allowed, then the unit will check
the synchronization. If synchronization is complete, then it will
make an uninterrupted transfer, where both contactors will be on
for a short while.
13.4. RUN MODE, MANUAL CONTROL
