MicroE 1500S Mercury - Manual (Page 18)

Troubleshooting
Problem
The Power/Calibration indicator will not come on.
Solution
• Make sure the M1500S 15-pin D connector is fully seated and connected.
• Confirm that +5 Volts DC is being applied to pin 12 on the M1500S 15-pin D connector and that pin 13 is connected to ground.
Problem
Can't get the SmartPrecision Alignment Tool "Signal" LEDs better than red or yellow; or the green, “ green” indicator doesn't
stay illuminated over the full length of the scale.
Solution
• 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. Refer to the appropriate interface drawing.
• Check that the scale is firmly mounted and can't jiggle or move in other than the intended direction.
• Make sure that the scale is clean over its entire length or circumference. Use the recommended Cleaning Scales procedure.
General Particle Removal

or a similar gas.
