1General safety instructions
Intended use
The controller is intended for the actuation of dock levellers with a hinged wedge lip or an
extendible lip.
Operating safety is ensured only when the controller is used as intended. No liability is
accepted for any use other than that described in these instructions.
Modifications are allowed only with the consent of the manufacturer. Unauthorised changes
render the manufacturer’s declaration void.
Information on safety
The system must be installed and commissioned by trained, qualified personnel only.
Only qualified electricians may work on the electrical systems. They must be able to assess
the work they are assigned, recognise potential sources of danger, and implement suitable
safety measures.
Installation work must be performed only when all power supplies are disconnected.
Observe the applicable safety and accident prevention regulations and standards.
Covers and protective equipment
Operate only with the system’s own covers and protective equipment.
Make sure that gaskets are properly seated and screw unions adequately tightened.
Replacement parts
Use only original replacement parts.

2Recommended installation
Your dock leveller can be put into operation quickly and safely when you follow the
recommended procedure below:
• Install the housing
• Check the power supply connection
• Wire the dock leveller to the controller
• Rapid adjustment
The dock leveller can now be operated.
• Install additional components
• Program additional components and functions
3Installing the housing
The dock leveller controller must be fitted vertically to a plane foundation free of vibrations.
The installation site must be seen clearly from the dock leveller room.

4Check the power supply connection
Warning - Danger to life from electric current!
Switch the mains OFF and check that the cables are de-energised
Observe the applicable regulations and standards
Make a proper electrical connection
Use suitable tools
Important note – External fuse!
Control must be saved against short circuit and overload by an external fuse, max.
10A delayed, in the mains supply. An automatic cut off switch is required, regarding
the supply for three-phase or single-phase.

4Description of dock-leveller functions
The rapid adjustment procedure must have been completed and the dock leveller has to be
at its home position
Dock leveller with hinged lip
Pressing the “Open” button
The platform is raised. The hinged lip
automatically folds out to the top limit
position.
Releasing the “Open” button
Platform stops rising and is slowly lowered.
The process is complete when the hinged lip
rests on the loading surface.
Movement across the dock leveller is now
Pressing the “Auto return” button
The dock leveller is automatically raised and
then lowered again until its home position is
reached

20
Dock leveller with telescopic lip (2 valves)
Pressing the “Open” button ①
The platform is raised.
Releasing the “Open” button
Platform stops rising and is lowered after
2 seconds, provided that no further command
is issued.
Pressing the “Telescopic lip” button ②
The telescopic lip extends.
Releasing the “Telescopic lip” button
The telescopic lip stops moving and the
platform is slowly lowered.
The process is complete when the telescopic
lip rests on the loading surface.
Movement across the dock leveller is now
possible.
Telescopic lip correction
If the telescopic lip is extended, it is retracted by pressing the “Open” button ①.
