can be used to aid installation and calibration.
INSTALLATION
Ensure scale, readhead optical window and mounting faces are clean and free from obstructions.
Connect the readhead to receiving electronics and power‑up. The set‑up LED on the readhead will flash.
Install and align the readhead to maximise signal strength over the full axis of rotation as indicated by a Green flashing LED.
CALIBRATION
Cycle the power to the readhead to initiate the calibration routine. The LED will single flash Blue.
Rotate the axis at slow speed (< 100 mm/s), ensuring the readhead does not pass a reference mark, until the LED starts double flashing Blue.
Reference mark
Move the readhead back and forth over the reference mark until
the LED stops flashing.
No reference mark
If a reference mark is not being used, the calibration routine should now
be exited by cycling the power. The LED will stop flashing.
The system is now calibrated and ready for use. Calibration values, Automatic Gain Control (AGC) and Automatic Offset Control (AOC) status are stored in readhead non-volatile memory at power down.
NOTE:
If calibration fails, restore factory defaults by obscuring the readhead optical window on power-up
. Repeat the installation and calibration routine.
