4. Using the table handswitch.
4.1 Initial start-up
Caution! Before using the table for the first time or in the event of
a malfunction, a manual reset (initialization) must be performed.
The reset position is reached at a table height of =< 650 mm. When op-
erating the table, the user must always make sure that the travel path is
free from obstacles (in particular below the table). The system is initial-
ized by pressing the button on the table handswitch. This must be
pressed and held down until the drives reach the lower stop position. As
soon as the drives reach the lower stop position, it is necessary to release
the button for 2-3 seconds and then press and hold it down for a fur-
ther 5 seconds. Initialization is now complete. The system is lowered by
5 mm and then raised again during initialization. Please do not release
the button during initialization.
Caution! If the button is released before the operation has been
completed then initialization will be interrupted and has to be
repeated. If initialization is interrupted then the system cannot
travel upwards.
If a safety stop has been set then it is important to note that the system
must travel to the lower stop position before initialization can be start-
ed. To override the set safety stop, it is necessary to press the button
a second time after the preliminary stop is reached to cause the system
to travel to the top end stop with approximately half its drive speed.
After a successful reset, the system travels the first two times to the
topmost position and then approximately 3 mm back again.
