1 Down key
2 Up key
To synchronise both lifting axes, they must now be initialised. Unless done
previously, connect the Wire Station WS 540 to the power grid.
The DESKLINE system is initialised by pressing the Down key on the hand-held
unit (fig. 1, item 1). The key must be kept pressed until the drives have reached
the lower limit position. Once all drives have stopped at the lowest limit position,
the Down key must be released for 2-3 seconds and then kept pressed for a
further 6-8 seconds. The initialisation is then completed. The system is lowered
and raised again by 5 mm during the initialisation. Under no circumstances,
release the Down key during the initialisation.
Synchronisation procedure

Keep the Down key on the hand-held unit pressed until the drives have
reached the lower limit position.

Release the Down key for 2-3 seconds.

Now keep the Down key pressed again for a further 6-8 seconds.

After successful initialisation, move the lifting axes with the Up key to the
uppermost position.
Note:
If the key is released before the operation has completed, the
initialisation is interrupted and must be begun again. No downward
travel of the system is possible if the initialisation was interrupted.
