Troubleshooting
Problem
The Sensor LED indicator won’t turn on.
Solution
• Make sure that the OPS Series electronics’ 15-pin D-sub connector is fully seated and connected.
• Confirm that +5 Volts DC is being applied to the OPS Sensor. Refer to the OPS interface drawing for
proper pinouts.
Problem
Can't get the OPS Series electronics’ "Signal" OPS better than red or yellow; or the green, “ Proper
Alignment” indicator doesn't stay illuminated over the full length of the scale.
Solution
• Verify that the sensor is mounted in the correct orientation with reference to the scale and scale
mounting reference edge. Refer to the Interface Drawing.
• Verify that the sensor has been aligned to the scale and that the mounting screws are tight. Check the
dimensions for the mechanical mounting holes (and clamps if any) to make sure that the sensor is
correctly located over the scale in the Y and Z dimensions. Refer to the Interface Drawing.
• Check that the scale is firmly mounted and can't jiggle or move in any direction.
• Make sure that the scale is clean over its entire length or circumference.
