MODEL 121 Installation Instructions
■STEP 1
▲Remove the shipping sticker. Applying pressure only to the hollow end of the encoder hub, slide the Model 121 encoder over the motor shaft until the base plate of the encoder rests firmly against the motor face.
▲CAUTION: DO NOT USE UNDO FORCE. The encoder should slide easily onto the motor shaft or correct alignment may be compromised.
■STEP 2
▲While maintaining a light but firm pressure (approx. 2-3 lb.) on the back of the encoder hub, securely tighten the socket head screw in the clamping collar using a 5/64” hex wrench. (Suggested torque range 115 to 160 oz-in)
▲CAUTION: While completing steps 2 and 3 make sure the cable does not apply any force or load to the encoder or correct alignment may be compromised.
■STEP 3
▲Install two screws (4-40 or M3 maximum) with the flat washers provided through the holes in the encoder base. Tighten each mounting screw ½ turn alternating between both screws until tight. (Suggested torque of approx. 160 oz-in) For additional security, a drop of Loctite 222 can be added to the threads of the screws
