Our objective was to design encoder systems that would be small enough to fit into densely packed OEM equipment designs, affordable enough for cost-sensitive applications and easy enough to enable installation, setup and alignment by assemblers with little training. We are pleased to say that all of these goals have been realized with the introduction of Sensor shown actual size the Mercury family of encoders M10 T TTa aab bbl lle ee O OOf ff C CCo oon nnt tte een nnt tts ss SYSTEM ILLUSTRATION PAGE Encoder with Linear scale 2 Encoder with Rotary scale 3 INSTALLATION INSTRUCTIONS Encoder System Mounting - Linear 4 Encoder System Alignment - Linear 5 Centering the Index & Calibration - Linear 5 Encoder System Mounting - Rotary 6 Encoder System Alignment - Rotary 7 Centering the Index & Calibration - Rotary 7 REFERENCE SECTION Installation of Linear Scales 8 Grounding Instructions 9 Recommendations for Power 9 Customer Interface Cable Requirements 10 Serial Output Specifications 11-12 SMARTPRECISION SOFTWARE INSTALLATION 13-19 SPECIFICATIONS Operating and Electrical 20 Output Connector Pinout 20 Serial Output 21 Operational Modes: Standard Communication 21 Serial Output Specificattion 22 Operational Modes - Trigger Approach Diagram 23 Serial Data Format 24 ENCODER TROUBLESHOOTING Selected Topics 24 Cleaning Scales 25 Contact MicroE Systems Back Cover Follow standard ESD precautions.

Use 2 washers per mounting screw. Benching pins may be used to locate each sensor if the system mechanical tolerances are adequate. See data sheet for alignment tolerances, or keep mounting screws loose for sensor alignment if benching pins are not used. Attach the scale to the base slide. Reference the preferred datum on the interface drawing for either end or center index orientation. Depending on the mount...
