It is only allowed to lift or to lower the MCS with load. Otherwise a MCS without load
can cause an unequal. After it, this MCS switch-off the complete system and the red
light (disturbance) is lighting.
Accordingly, the number of the lifting wheels must agree with the number of the MCS.
In the case of disturbance, raise or lower the lift only in the „single“ mode.
5.4 Lowering the vehicle (mode synchronous)
• Check the dangerous places of the lift and be sure that there are no objects or people in
the immediate area of the lift or on the lift.
• Lower the lift at the height for working or in the lowest position.
Press the button „lowering“ (Synchronous) at the operating unit. The MCS raises a little
bit (unlocking the safety device), before the lowering starts.
• When lowering a vehicle, hold the button 2 pushed, until the lift has reached the height of
250mm; the lift stops automatically. Then push the button 2 again.
• The lift will continue lowering again. When a column stops during lowering between the
height of 0 and 250mm, use button 4 to lower all columns in single operation mode to the
ground (important for zeroing (referencing) the columns again). You hear an acoustic
signal until the lift reaches the lowest position.
In case of an SYNCHRON ERROR (shown on display; means unequal position error
of the columns) bring all columns back in the same position height, by using the
buttons 3 or 4 and watching the positions on the display. When all columns are at
the same height (position) again, you can operate the system again.
