16. Using a suitable cable tie, engage a forcemeter across the motor pulley.
Apply a horizontal force of 24kg to the belt. Maintaining this force, tighten
the two securing screws.
17. Remove the forcemeter. Do not remove the cable tie as further adjustment
may be necessary.
18. Ensure that the belt clamp is midway between the two pulleys.
19. Using a tension meter (Part No. 190279), check the timing belt tension either
side of the cable clamp is between 42Hz and 48Hz. Check the two readings
are within 1Hz of each other.
NOTE
Adjust the position (between the two pulleys) of the belt clamp to achieve
the 1Hz deviation.
20. If adjustment is not required, go to Step 25.
21. If adjustment is required, slacken the two securing screws as detailed in
Step 9.
22. Adjust the timing belt tension using the cable tie.
23. Tighten the locknut.
24. Repeat Steps 19 to 23 until the correct tension is achieved.

Replacing the Encoder and Encoder Strip (Linear Servo Motor Systems Only)
If the encoder or encoder strip needs to be replaced, there is a special tool kit
available which is used to maintain the correct alignment. The tool kit uses a
scale applicator, this temporarily replaces the encoder for laying the encoder
strip.
The encoder set up involves setting the height and yaw correctly so that the
encoder travels at the focused distance for reliable reading.
The tool kit is available from ASM Customer Support Group, contact the help
desk for details.
