Adjusting the limit switch
1. Take off the rotary pushbutton (3) and cap
(1), unthread the five fastening screws (2)
and lift off the plastic cover (9) together
with the display, taking care not to dam-
age the ribbon cable (between PCB and
display).
2. Use a knife to cut an opening at the
marked location (4).
3. Push the connector (11) with cable
through the opening and secure the prox-
imity switch (7) on the cover with a dot of
glue.
4. Remove the jumper (8801-2267) at the
socket X7 of the top board and insert the
cable connector (11).
5. Guide the cable in such a manner that the
plastic cover can be placed back onto the
positioner. Insert the fixing screws (2) and
screw tight. Attach the clamping plate (8)
onto the proximity switch.
6. Attach the rotary switch (5). Make sure
the flattened side of the positioner shaft is
turned so that the rotary switch (5) can be
attached with the metal tag next to the
proximity switch.
7. On start-up of the positioner, set the op-
tion inductive alarm under Code 38 from
No to YES.
