Restoring Factory Defaults; Switching Automatic Gain Control (Agc) On Or Off - Renishaw QUANTiC RTLC40 Installation Manual

Restoring factory defaults

When realigning the readhead, reinstalling the system, or in the case of continued calibration failure, factory defaults must 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:
1. Switch system off.
2. Obscure the readhead optical window (using the black 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.
3. Power the readhead.
4. Remove the spacer or, if using, the connection from the 'Remote CAL' output pin to 0 V.
5. The LED will start continuously flashing indicating factory defaults have been restored and the readhead is in installation mode.
6. Repeat the 'Readhead set-up' procedure on page 22.
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.
