3.1
Description
The Operating principle section provides a general description on how the AutoShuttle functions work and how they are
interdependent.
Because the control structure of the product is so complex, it is not possible to describe all combinations. Similarly, it is
not possible to describe all influencing factors. Only a selection of such factors are indicated. A good aid is found in the
descriptive sections of the repair manual and in the parameter descriptions in particular.

Driving in the drive wheel direction,
page 3 - 2
The speed control [L1] is moved to the opposite driving direction.
Parameter settings Deceleration when reversing.
The drive motor
[M1],
page - 000
works as a generator and converts the kinetic
energy of the truck into electrical energy via the transistor regulator Controls for lift-
ing, driving and peripherals (ACC). This reduces the speed of the truck.
The excess energy is fed back to the truck battery Truck battery..

Emergency reversal
The Hall sensor [A5:S317] is immediately activated. The card Electronic circuit
board interprets this signal as a command to the transistor regulator
[T12],
page - 000
to run the drive motor[M1],
page - 000
at a reduced speed in the fork
direction as long as the button is pressed. The normal drive command signal re-
ceived from [L1] is blocked until [L1] is released and returns to neutral position.
