When the lever for the When the lever for the speed controller (5) is actuated the speed controller (5) is actuated the drive motor regulator (1) sends drive motor regulator (1) sends
a drive voltage to the drive motor (6). A a drive voltage to the drive motor (6). A pulse transducer in the upper bearing of the drive pulse transducer in the upper bearing of the drive
motor restores the motor speed to the regulator, which adjusts the drive voltage until its motor restores the motor speed to the regulator, which adjusts the drive voltage until its
speed corresponds to the speed

When the control lever for electrically controlled lifting (7) When the control lever for electrically controlled lifting (7) is actuated the regulator for is actuated the regulator for
the drive motor (1) sends a voltage to the drive motor (1) sends a voltage to the lift motor contactor (8), which starts the the lift motor contactor (8), which starts the lift lift
motor (9). The drive motor regulator also forwards via the motor (9). The drive motor regulator also forwards via the CAN link (2) the magnitude CAN link (2) the magnitude
of the response on the control to the MDI (4) of the response on the control to the MDI (4) and the lift speed is then controlled by the and the lift speed is then controlled by the
MDI, which provides an equally high control voltage in proportion to MDI, which provides an equally high control voltage in proportion to the control level to the control level to
the control valve (10), which in turn provides a proportionally equally high flow of the control valve (10), which in turn provides a proportionally equally high flow of

On trucks with manual hydraulic valves the modulation of the valve is controlled directly On trucks with manual hydraulic valves the modulation of the valve is controlled directly
by the position of the lift
