7.8 Troubleshooting
Problem Solution
The Power/Calibration indicator will not
come on.

Make sure that the SmartPrecision II Electronics 15-pin D-
sub connector is fully seated and connected.

Confirm that +5 Volts DC is being applied to pin 7 and 8 on
the SmartPrecision II electronics 15-pin connector and that
pins 2 and 9 are connected to ground.
Can't get the SmartPrecision II
Electronics "Signal" LEDs better than
red or yellow; or the green
“Proper
Alignment” indicator doesn't stay
illuminated over the full length of the
scale.

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 other than the axis of motion.

Make sure that the scale is clean over its entire length or
circumference.
The green Power/Calibration indicator
LED or limit LEDs are flashing
unexpectedly. 
Part of the normal setup procedure is to activate the
SmartPrecision II Electronics Calibration/Setup process by
pressing the recessed button in the electronics module.

The Power/Cal. LED or limit LEDs will begin to flash until
the relevant setup process is complete. See the
instructions beginning at
Section 5.1.1 Sensor Alignment .
Can't complete the Calibration/Setup
process - the green Power/Calibration
indicator doesn't stop flashing. 
Verify that the sensor is mounted in the correct orientation
to the scale for the desired index mark. Refer to the
Interface Drawing.

Refer to Section 4.2 Verify Sensor Mounting Surface
Height to ensure proper sensor alignment and index
marker operation.
