11.3.8 Lifting Table Functions
Lifting table up function
Requirements for detecting that the lifting table is up:
30-35 pulses from the incremental disc
Check performed by software (see Section (11.3.7 Board Clamping Functions
J
459 ) )
Dynamic response for board clamping of approx. 500 ms
Lifting table down function
Requirements for detecting that the lifting table is down:
30-35 pulses from the incremental disc
Proximity switch on the lifting table cylinder
Dynamic response for board release of approx. 480 ms

X If the travel times are not inside the tolerance range or if error messages appear during production,
adjust the travel times as follows:
X Adjust the valve on the lifting table cylinder, so that you get the following values:
X If malfunctions occur during the downwards movement or if the board is shaken, reduce the lowering
speed accordingly.
Setting valve anticlockwise: Decrease the lifting table moving time
Setting valve clockwise: Increases the lifting table moving time
11-21: Time needed to move lifting table down with lifting table plate
X The lifting table will be moved up and the travel
time will be displayed (see diagram).
X Press the

button again to
move the lifting table downwards and to view
the travel time for the downwards movement.

11.3.8.2 Setting the Lifting Table Unit [00358684-05]
11.3.9 Checks After Mechanical Work on the Conveyor
Check: The distance between the top edge of the conveyor belt and the top stop should be 6 mm.
11-22: Setting the damping unit
The damping unit (1) allows the lifting table to
move gently upwards. When the PCB is clamped,
it also prevents excessive bounce by the PCB.
X Check whether the damping unit is fixed with
the locknut (2) in the mounting block and that
the plunger (3) of the damping unit is just
touching the actuator (4). In this default
setting, the lifting table should move up gently.
X If this is not the case, loosen the locknut at the
mounting block and turn the damping unit
approx. one rotation into the mounting block..
X Move the lifting table upwards, with the help of
the software.
X The lifting table should move gently upwards.
The PCB clamping should not engage audibly
and there should be no PCB clamping error
message.
X Check the speed of the lifting table and correct
where necessary.
