RSF encoder for turning station, from item no. 00319907S01
Test equipment
Precision test pin, dia 1.4, from item no. 00326160-01
Precision test pin, dia. 1.5
, from item no. 00326161-01
Precision test pin, dia. 1.6
, from item no. 00326162-01
Star gauge from item no. 00326164-01
● Remove the X7 connector from the distributor board.
● Undo the two hexagon socket screws (M2.5 x 5) of the encoder conversion board.
● Undo the two hexagon socket screws (2.5 x 8) and remove the entire encoder (see item 8 in Fig. 13.5.1,
page 13 - 24.
● To reinstall reverse the sequence of operations.
Adjustment work
● Fix the star using the star gauge.
● For correct adjustment of the distance between the encoder and the segment underside use the precision
test pin, dia. 1.5mm.
Check the correct adjustment with the two other precision test pins:
– When using the precision test pin with a dia. of 1.6 mm you must not be able to slide the pint in-
between the encoder and the segment underside.
– When using the precision test pin with a dia. of 1.4 mm you have to be able to easily insert the test pin.
