Adjustment Instructions MTC 2 5 Feed axes

12/2007 Edition 5.2 Zero offset, removal position and transfer position

5.2 Zero offset, removal position and transfer position

NOTE

You must carry out the steps described for checking and calibrating the removal positions

for WTCs 2 - 5 on tower 1 and

for WTCs 2 -4 on tower 2.

The removal position for WTC 1 corresponds to the zero position (zero offset).

WARNING

You may only check and calibrate the positions of the feed axis with the correct zero position and

correct transfer positions of the lifting axis.

5.2.1 Tools and accessories

– Adjustment gauge, WTC

– Adjustment gauge, WTC XL

5.2.2 Preparatory measures

NOTE

The positions must be checked and calibrated with cassettes in the towers. There must be a WTC

in the bottom level of each cassette.

 Set the MTC 2 up completely with empty cassettes (see the User Manual).

 Set up every cassette with an empty WTC in the bottom level.

5.2.3 Checking and setting the zero offset

 Carry out the relevant preparatory measures (see section 5.2.2 "Preparatory measures").

 Select SITEST --> MTC --> Settings

 Press the button "Teach zero point"

 Check the position of the driver with the button "ENGAGE". In case the driver did not engaged

successfully you must determine the middle of the notch of the waffel pack tray.

The accurate adjustment is described below:

 Determine the minimum position of the notch Fig. 5.2 - 1.

Fig. 5.2 - 1 Minimum position

 Determine the maximum position of the notch Fig. 5.2 - 2. at which the driver just engages no

more.

Fig. 5.2 - 2 Maximum position

 Now calculate the middle position at which the driver will always engage.

e.g. |-257| + 596 = 853 divided 2 = 426µm

426 + the minimum pos. or maximum pos. - 426 = approx.169µm

Fig. 5.2 - 3 Correct position for the driver

 Check the driver position. The driver now should be correctly in the middle position of the notch

of the WTC.

 Press the button "ACCEPT"

 Check the position of the driver for the other cassettes.
