ance which must exist between sensor cables and housing (Fig. ’B’, section

toothed belt tension must be visually rechecked as shown in Fig. ’G’ and ’H’, and by
lightly tapping on the toothed belt with a finger.
If necessary or in case of doubt the toothed belt must be retensioned as described
in paragraph 3.2!
Attention! After every loosening of a shaft encoder the toothed belt tension must
