MicroE 1000V Mercury - Manual (Page 13)

Troubleshooting
Problem
The Power/Calibration indicator will not come on.
Solution
• Make sure the M1000 15-pin D connector is fully seated and connected.
• Confirm that +5 Volts DC is being applied to pin 12 on the M1000 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 appropriate the 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.
Problem
The green Power/Calibration indicator is flashing unexpectedly.
Solution
• Part of the normal setup procedure is to activate the SmartPrecision Alignment Tool calibration process by pressing the recessed button on the
SmartPrecision Alignment Tool connector body. The Power/Calibration indicator will flash until calibration is complete.
