Secure base to mounting surface using two screws. Transfer Adhesive: Peel off paper backing, place centering tool into center hole of base, slip centering tool onto shaft and slide base and centering tool down onto mounting surface as one piece. Press to form a good bond, then slip centering tool off shaft and continue with standard mounting instructions. 2. Codewheel Placement Place codewheel onto shaft with pattern-side down towards base. 3. Codewheel Installation Position spacer / installation tool onto codewheel. Spacer / installation tool provides an air gap of 0.07" 0.03". Press down firmly until tool bottoms out on base latching ears. 4. Cover Installation Place housing (cover) on. With thumb and finger, squeeze ears together to insure that cover fully latches. Assembly InstructionsWed, 04 Jun 2008 14:15:00 PDT http://usdigital.com/support/assembly/e3-assembly-instructions For Shafts Greater Than 0.394" (10mm): 1. Base Mounting Secure the base to the mounting surface using two or three screws (sold separately). If a centering tool is used, slip it over the shaft and into the center hole of the base. Tighten the mounting screws and then remove the centering tool. 2. Spacer Installation Push the spacer tool onto the bottom section of the hub/disk assembly. Make sure the spacer tool snaps only on the lower part of the hub. Align hub set screws as shown in drawing. 3. Hub/Disk Assembly Installation Slip the hub over the shaft until it bottoms out against the spacer tool. Make sure the spacer tool clears the mounting screws on the base. Tighten both set screws with the hex wrench provided while pressing down on the hub. Remove the spacer tool. 4. Encoder Module Installation Orientate the module with the connector pins toward the top. Slide the module from front to back, being careful not to damage the disk. Stop when the two alignment pins on the base fit into the holes of the module. Secure with two 4-40 1/2" pan head screws (supplied). 5. Cover Installation Place the cover over the assembly and secure with the two 4-40 5/8" flat head screws (supplied). For Shafts Less Than or Equal To 0.394" (10mm): 1. Base Mounting Secure the base to the mounting surface using two or three screws (sold separately). If a centering tool is used, slip it over the shaft and into the center hole of the base. Tighten the mounting screws and then remove the centering tool. 2. Spacer Installation Place the spacer tool around the shaft, flat on the base. 3. Hub/Disk Assembly Installation Slip the hub over the shaft until it bottoms out against the spacer tool. Tighten the set screw with the hex wrench provided while pressing down on the hub. Remove the spacer tool. 4. Encoder Module Installation Orientate the module with the connector pins toward the top. Slide the module from front to back, being careful not to damage the disk. Stop when the two alignment pins on the base fit into the holes of the module. Secure with two 4-40 1/2" pan head screws (supplied). 5. Cover Installation Place the cover over the assembly and secure with the two 4-40 5/8" flat head screws provided. Assembly InstructionsWed, 04 Jun 2008 13:44:00 PDT http://usdigital.com/support/assembly/e7p-assembly-instructions View the PDF version of this document. 1. PCB Installation Position PCB so that connector lines up with flat side of base. Push PCB onto base by hand so that two guide posts fit into associated PCB holes. 2. Base Installation 2a. Standard: Secure base to mounting surface using either two #2-56 x " socket head cap screws or two #4-40 x " low profile socket head cap screws. Note that when using 0.750" or 1.280" bolt circles, the heads should be low profile to insure plenty of clearance between top of screw heads and codewheel. 2b. Transfer Adhesive: Slip centering tool over shaft and into center hole of base. Slide both parts down shaft until they contact mounting surface. Press base firmly to assure good adhesion. Remove centering tool. 3. Codewheel Installation Set codewheel on shaft with disk facing base. Place spacer tool over codewheel with a recess area over connector. Push tool down by hand until it bottoms out against base tabs. Remove reusable spacer tool. In order to prevent permanent damage to motor bearings (especially on small diameter shaft motors), it is recommended that the far end (drive end) of the motor shaft be supported while installing the push on hub. 4. Cover Installation Snap cover onto base. Assembly InstructionsWed, 04 Jun 2008 00:00:00 PDT http://usdigital.com/support/assembly/e4-assembly View the PDF version of this document. 1.
