Step 1
Ensure that you have the correct hardware for your installation
and that it all fits properly. Mating parts should line up, bolt
thread pitches and lengths should be appropriate and all the tools
should be the correct type and size and should be at hand. Have
the manufacturer’s installation instructions handy, since there
may be some critical measurements or pieces of hardware required.

Step
2
Check that there are no burrs on the mating shaft and that the shaft
length is correct for the encoder. Attach the tether arm to the encoder
body and slide the assembly onto the mating shaft. Follow the manufacturer’s
recommendations for distance between the encoder body and the housing
to prevent overstress of the tether. Do not tighten the shaft clamp
on the encoder, yet. |

Step
3
Rotate the tether arm until it is at the correct orientation and is
aligned with the mounting feature on the shaft housing. Use the appropriate
hardware to secure the tether arm in that position. Check to make
sure that the tether is still in it’s “unstressed’
condition (move the encoder slightly if necessary) and then tighten
the shaft clamp on the encoder. |
|
Step 4
Using a dial indicator on the outside of the encoder body check
the runout as you rotate the shaft by hand. If it exceeds the manufacturer’s
specifications you will need to re-install the encoder (Excessive
runout will cause premature bearing failure.) Otherwise, your installation
is complete.
