Restoring factory defaults
When realigning the readhead, reinstalling the system, or in the case of continued calibration failure, factory defaults should be restored.
NOTE: Restoring factory defaults can also be carried out using the optional ADTi-100 and ADT View software. See www.renishaw.com/adt for more information.
To restore factory defaults:
u
Switch system off.
u
Obscure the readhead optical window (using the spacer supplied with the readhead ensuring the cut-out is NOT under the optical window) or connect the ‘Remote CAL’ output pin to 0 V.
u
Power the readhead.
u
Remove the spacer or, if using, the connection from the ‘Remote CAL’ output pin to 0 V.
u
The LED will start continuously flashing indicating factory defaults have been restored and the readhead is in installation mode (flashing set-up LED).
u
Repeat ‘Readhead set-up’ procedure on page 12 .
Switching Automatic Gain Control (AGC) on or off
The AGC is automatically enabled once the system has been calibrated (indicated by a Blue LED). AGC can be manually switched off by connecting the ‘Remote CAL’ output pin to 0 V for > 3 seconds < 10 seconds.
The LED will then be solid Green.
NOTE: AGC can be switched on or off using the optional ADTi-100 and ADT View software. See www.renishaw.com/adt for more information.
