7.7.2.1 Image structure and functionality
Electronic pump control can be performed in
automatic or manual mode. The correspond-
ing display screens are shown.
Automatic mode
When the diesel engine is running, the display
screen for automatic mode appears (Fig.
178).
The pump runs in accordance with the pa-
rameters displayed (178/1). The status of the
piston detector is monitored during the set
number of pump cycles. If a status change
takes place during these pump cycles (pause
time and pump run time) the piston has
moved in the monitored distributor. If no sta-
tus change takes place, an error message
appears (also in the main control display).
The middle area of the display screen (178/2)
indicates the current operating status of the
pump and piston detector. If the pump is run-
ning or the piston detector changes its status,
the display and text change.
The progress indicator (178/3) shows the ex-
pired and outstanding pump run time and
pause time with colored bars and percent-
ages.
F2 exits the pause time. The pump starts.
