These are the buttons shown in this screen:
1. Position sensor scale: Depending on where the
stroke sensor is placed, the user must select one
of these two options (see Figure 15).
Figure 15: Position Sensor Scale Selection
When the cylinder’s plunger movement and the stroke
sensor’s wire are extending (positive movement),
the movement is called Direct. When the cylinder
is extending but the stroke sensor wire is retracting
(negative movement) the movement is called Indirect.
Refer to Figure 16 for further details.

2. Cylinder calibration selection: The user must set
if the calibration is going to be carried out or not,
depending on the type of cylinder used. Refer to
Figures 17 and 18 for details.

DIRECT
INDIRECT
Calibration operation must be carried out depending on
how the hook of the stroke sensor is attached. If the
hook is attached to the cylinder rod, or if an internal
stroke sensor is used, the calibration must be done. If
the hook is attached directly to the load to be moved,
then the calibration must be avoided.

3. Cylinder movement type: This button allows the
operator to choose between pushing and pulling
applications.
