Recommended actions
We recommend using a PLC to move from stored (saved_ memory positions. The hand switch can
be reconfigured completely via the PLC. We also recommend a hand switch for setting up pro-
cedures, as the execution has advantages with this method.
7.3.7 Functional description of the PLC wiring
The lifting column is moved by populating the inputs with a certain pattern. The outputs from the
PLC or another controller must be present on the relevant outputs of the PLC/PC data interface
at high potential to execute a wanted action.
A low level at the inputs counts as not switched or logical 0.
To execute a movement, the input I10 (terminal 12) "PLC action" must be at high potential. This
is how the PLC/PC data interface is given the command to execute the movement.
All inputs must remain enabled during the entire travel process.
The movement action is achieved by creating the corresponding pattern for the selected mode (4
or 8 bits).
