42 OPI-POWER LIFT HDL 15000 - HDL 18000-V1.0-EN
Problem: The lift arms cannot be swivelled in or
out.
possible causes: Repair:
The unlock switch is not
pushed, or is defective
Have the button
checked
No or insufficient com -
pressed air available
Check air pressure
Compressed air line de-
fective air flow noises
Check the path of the
compressed air line. If
required, inform custom-
er service
6.1 Moving onto an obstacle
If the lift lowers onto an obstacle, the system auto-
matically switches off, as soon as an unevenness of
approx. ± 40 mm is detected.
6.1.1 Remove the obstacle
Access to the DIP switch may solely
be done by a trained and authorised
specialist and only with the main
switch turned off.
• Remove the covers on the unit and the electrical
box.
• Push the reset button 1 on the circuit board and
hold it down. (See Figure 5)
Figure 5: Circuit board - axis controller
• Release the reset button.
• Set all DIP switches to the „off“ position.
• Place the DIP switch 1 and 2 to the „on“ position.
This process can only be done when
the lift is not in the uppermost position.
• Observe the vehicle and the reaction of the ve-
hicle.
• Push the “▲” button until the obstacle can be re -
moved.
• The lift rail that is higher must be lowered with the
help of the dip switch, (see Section “5.4”)
The lift rails first move to unlock up -
wards.
For large differences of the two lift rails it can be
practical in some circumstances, to lift the lower lift
rails.
• After balancing the lift rail a reset must be done
as follows:
• Set all DIP switches to the „off“ position.
• DIP switch 5 in the „on“ position.
• Push the „▼“ button until the lift (both lift rails)
have reached the lowest position and the warn-
ing signal can no longer be heard.
• Push the DIP switch 7 to the „on“ position.
• DIP switch 5 remains in the „on“ position.
• Push the DIP switch 7 to the „off“ position.
LED K700 must light continuously.
• If necessary a reset of the pics must be done. (See
Section 5.4 Axle controller – zeroing Pic)
• An additional light diode must flash every second.
• The lift must be raised and lowered several times
without a vehicle while observing the entire lifting
and lowering process.
• The covers must be replaced.
6.2 Emergency discharge of the lift
An emergency discharge is an ac-
cess into the lift controls and may only
be done by experienced specialists.
The emergency discharge must be
done in the following described se-
quence, otherwise it can lead to
damage and hazard to life and limb.
Any kind of external leakage (defec -
tive hydraulic pipe) is not permitted
and must immediately taken care of.
This is absolutely necessary especially
before an emergency discharge.
An emergency discharge can only be
done by personnel who are trained to
operate the lift.
Reason which make an emergency discharge nec-
essary are for example, electrical blackout, for er -
rors in the lowering valves, etc.
For a power outage or defective valves, there is the
option of lowering the lift to the lowest position with
some manual movements, so the vehicle can be
moved from the lift.
