Select "Open WPTC lock".
Manually move the WTC completely out of the cassette onto the rail of the feed axis.
Now the WTC (1) must have contact at the lower third of the ramp of the feed axis (2) (see
figure below).
Select "Close WPTC lock".
Move the WPC back into the cassette so that the WTC interlock is locked.
Repeat this check for the other cassettes.
WARNING
Before moving the lifting axis, ensure that
- the cassettes and the WTCs are always fully inserted in the tower,
- the driver is disengaged and
- the WTC interlock is locked.

4.2.5 Calibrating the zero offset
Note
The reference run might fail e.g. after the replacement of a drive.
In that case it is necessary to preset an approx. zero offset for the corresponding axis.
SITEST -> MTC-Axes -> Feed- resp. Lifiting -Axis -> Positions...
Edit the zero offset and enter a value in between the following range of value:
Lifting axis: from 500.000 up to 600.000
Feed axis: from -30.000 up to 0

of the selected step size.
Close the window with "Accept".
Check the refill positions of the lifting axis (see section 4.2.3 "Checking the refill positions").
Check the transfer positions of the lifting axis (see section 4.2.4 "Checking the transfer positi-
ons").
Check the end positions of the lifting axis (see section 4.3.2 "Checking and calibrating the end
positions").
