Chapter 4 - Operation
4.1 Basic operation
The following items are discussed below:
For platform control (PCU), see Fig. 2 and Fig. 3. For chassis operation (ECU), see g. 4.
Main power supply and safety
1) The ignition key provides power to the machine, for which three operating modes
are available. When the key switch is set to the left position, the platform operating mode is switched on;
when the key switch is in the right position, the chassis operating mode is activated; when the key switch is in
the middle position, the switch-off mode is activated.
Note: the key can only be inserted or removed when it is in the middle position.
(some products are optionally equipped with keys that can be inserted in the three positions, or removed).
2) An emergency stop switch is installed on the chassis and platform controls. The two switches are connected in
series. The work can be done when the two switches are removed. The power supply is interrupted as soon as
an emergency stop switch on the chassis or platform is pressed. The safety function is based on a complete
loop that can be interrupted when an emergency stop switch is activated.
3) The functions of driving, steering, lifting or lowering can only be started when the dead man switch on the
handle is pressed.
Lifting and lifting safety
1) The slope sensor on the chassis is used to indicate whether the chassis is horizontal.
2) If the exit protector has been installed, the platform can only be raised above the set height if
the exit protector has been initialised.
3) The load shall not exceed the nominal working load of the machine model.
4) The platform can be raised or lowered from two positions, the chassis or the platform.
The operating position can be selected via the key switch.
The platform can only be raised or lowered via the toggle switch on the chassis.
The platform operator can choose the drive/lift mode on the platform. The up and down direction and speed can be
controlled by moving the lever. The platform can be raised by moving the lever forwards and lowered by moving it
backwards.
5) If the overload protection is available on the machine and the platform is overloaded, the main control
(ECU) of the platform sounds an alarm and the controls are deactivated.
6) Failure of the lift/lower valve can be indicated by an error code in the LED of PCU and ECU.
Moving and relocation safety
1) The driving can only be controlled by the PCU lever. In this case, the key switch must be in the position
from the platform.
2) If it is intended to move the machine, make sure that you select the drive mode and the dead man switch on
the lever.
