1
) Pre ---selection means the DPS speed, which is automatically switched on when the driving direction is changed and which is
pre ---programmed with the button beside the shuttle lever. The pre ---programming is carried out so that when one of the dri-
ving directions is engaged, driver engages the desired DPS speed and then presses the button at least 2 seconds. During the
pre ---programming the clutch pedal must be depressed. Thus the selected DPS speed remains in the memory of AC 5 and
engages always when the driving direction in question is selected. If only one direction is pre ---programmed, the pre ---prog-
ramming is valid only for this direction. The DPS speed remains the same in the other direction.
The pre ---programmin is cancelled by pushing the button at least 2 seconds, when the shuttle is in the neutral.
2
) The two DPS automatic modes (Auto1 and Auto2) are selected with the three ---position rocker switch on the lever console. The
function is the same as on AC III. The switch has also a manual position.
3
) If a driver changes quickly from DPS speed 1 to 3, the speed 3 flashes immediately in the display (although the automatics
changes the speeds also via speed 2) and speed 3 stops to flash just when the gear change is completed.
4
) When the DPS is in the automatic mode (AUTO 1 or AUTO 2), it changes automatically down or up and informs with the flas-
hing arrow, if the automatics cannot do more and a driver must change up or down manually.
Note! The display has a background light when the current is switched on. Tractor image, DPS ---logo and outdoor temperature
(stationary) or driving speed (in motion) are visible always when the current is switched on. There is a connector (RS ---232) in the
lever console for connecting e.g. a micro---computer for re ---programming the control unit A1.
One arrow is blinking, if a driver does
not sit on the seat and driving
direction (F or R) has been selected.

Numbers show also fault codes. In the
test mode is shown a point, which is
tested or reset.
