Troubleshooting
Fault
LED on the readhead is Blank
LED on the readhead is Red and
I can't get a Green LED
Unable to get a flashing Green LED
over the complete axis length
Can't initiate the calibration routine
LED on the readhead remains single
flashing Blue even after moving it along
the full axis length
ATOM DX
linear installation guide
Cause
There is no power to the readhead
The signal strength is < 50%
System run-out is not within specification
Signal size is < 70%
The system has failed to calibrate the
incremental signals due to the signal
strength being < 70%
Possible solutions
Check you have 5 V at the readhead
For cable variants check correct wiring of connector
Check the readhead optical window and scale are clean and free from contamination
Restore factory defaults
(page 24)
and check alignment of the readhead. In particular;
– Rideheight
– Yaw
– Offset
Check the scale and readhead orientation
Check that the readhead variant is the correct type for the chosen scale

Use a DTI gauge and check the run-out is within specifications
Restore factory defaults
Realign readhead to obtain a flashing Green LED at the mid-point of the run-out
Recalibrate the system
(page 23)
Restore factory defaults
Realign readhead to obtain a flashing Green LED
Exit CAL mode and restore factory defaults
Check system set-up and realign the readhead to obtain a flashing Green LED along the full axis of travel
before recalibrating
