Operation of the dock leveller
This chapter describes all aspects of the operation of
the dock leveller. To ensure that work with the product
is safe, make sure that the following safety
instructions are observed.
Anyone operating the dock leveller must be
instructed beforehand. The owner should ensure that
the instructions are understood by all.
Besides, all operators should have read and
understood the instructions for use and the operation
instructions. Operators operating the platform
transfer bridge without supervision must be
instructed and at least be 18 years old.
1. Observe all movements of the dock leveller.
2. No person must be present in the movement
zone of the dock leveller when it is lifting or
lowering.
3.
The mains isolator must always be at position I
for loading. Otherwise the height movements of
the vehicle are not adopted by the dock leveller
during loading.
4.
Set the yellow-red mains isolator to position 0 in
an emergency. This interrupts all movements of
the dock leveller if you:
a) operate the mains isolator, or
b) disconnect the power supply, or
c) press the emergency stop switch.
Loading should be interrupted in this situation.
See restart interlock.
5. Make a visual inspection of the dock leveller
before daily start-up for safety reasons:
If everything is O.K. the dock leveller can be
switched on. Switch on the mains isolator and
briefly press the lift button. The dock leveller is
now ready for operation.
Safety wheel chock
If a wheel chock is required for safety purpose, the
button
is only active when the wheel chock is
applied to the vehicle.
Lifting
If you keep button
pressed, the dock leveller starts
lifting.
Releasing
the
button automatically lowers the
dock leveller to the floor.
Extend
When button
is pressed, the lip is extended during
which lifting and lowering movements are blocked.
To retract the lip, press the button.
If the automatic retraction time is active, the lip will
retract for the time set.
Free floating position
2 seconds after releasing the lift or extend button, the
dock leveller with the lip lowers onto the vehicle and
is at free floating position. The dock leveller follows
the height movements of the vehicle.
Electrical reclosing lockout
When the mains isolator or the emergency stop
button is switched on again, the electrical reclosing
lockout is active and the yellow warning blinks in the
display.
In this case, any traffic on the dock leveller
is prohibited.
Return / dock leveller at zero position
If loading is complete, the dock leveller can be
returned to zero position by pressing the RETURN
button.
The dock leveller lifts and then lowers automatically
to floor level without an additional press of the button.
Automatic return to zero position (optional)
When the vehicle has moved away, the dock leveller
returns to zero position automatically.
This function is only available if the required sensors
are installed. A visual and an audible signal must also
be installed.
Dock light (optional)
When the door obtains open position (sensor door
open), the dock light is switched on. When the door
leaves the open position, the dock light extinguishes.
Visual, audible warning signal (optional)
A warning signal is issued during automatic return.
Sensor door open (optional)
When the sensor door open is available, the dock
leveller lifts only when the door is open.
Safety wheel chock (optional)
The dock leveller can lift and extend only if the wheel
chock is applied behind the vehicle wheel.

tested by a specialist company.
