For correction function the wire must remain
without kinks or flattening.

Guiderollers(accessory)
Are used for applications where wire actuated
transducer and wire cannot be mounted in one
line.Usingguiderollersthewirecanbepulledout

• Maintain cleanliness of guide rollers at all
times.

incrementalorabsolute encoder(fig.5).
• Theencoder’sbreak-awaytorqueandopera-
tional torque must not exceed the admissable
value of 3 Ncm.
• Checkwhetherencoder’s(4) andcompensa-
tion coupling’s diameter comply (6).
• Loosen screws (2) and servo flanges (3);
remove plastic plug of the opening (7) in the
flange.
• Assemble encoder and wire actuated unit
together so that encoder’s shaft fits into com-
pensationcoupling(6) (grubscrew(5)mustbe
unscrewed).
• Mounttheservoflanges(3)tofixtheencoder.

• Tighten screws uniformly (2) to fix the servo
flanges to the encoder. Mount without force!

5. Adjustment
For adjusting the reference point loosen the
screws (2) until the encoder can be turned.
Rotate the encoder in arrow direction until the
reference point is reached; then re-tighten the
screws.
Attention: For reference point adjusting the
encodermustonlyberotatedincounter-clockwi-
se direction.
