Restoring Factory Defaults; Switching Automatic Gain Control (Agc) On Or Off - Renishaw TONiC FS T3 3 Series Functional Safety Installation Manual And Safety Manual

Reference mark phasing
1. Move the readhead back and forth over the selected reference mark until the CAL LED stops
flashing and remains off. The reference mark is now phased.
2. The system automatically exits the CAL routine and is ready for operation.
3. For the safety function to be valid, customer commissioning tests must be performed:
see 'Commissioning test' on page 14.
4. If the CAL LED continues double-flashing after passing the chosen reference mark many
times, it is not detecting the reference mark. Ensure that the correct readhead configuration is
being used. Readheads can either output all reference marks or only output a reference mark
where a reference selector magnet is fitted depending on the options chosen when ordering.
NOTE: The LED on the interface will flash blank when the reference mark is detected
(> 100 mm/s only). It indicates the presence of a reference mark, not the phasing status.
Calibration routine – manual exit
1. To exit the calibration routine at any stage press the CAL button. The CAL LED will
stop flashing.
2. For the safety function to be valid, customer commissioning tests must be performed:
see 'Commissioning test' on page 14.

Restoring factory defaults

When realigning the readhead, reinstalling the system, or in the case of continued calibration
failure, factory defaults must be restored.
To restore factory defaults:
1. Switch system off.
2. Press and hold the CAL button whilst switching the system on. The CAL LED on the
readhead will flash several times, indicating that the factory defaults have been restored.
3. Release the CAL button.
4. Check the 'Readhead mounting and alignment'
(see 'System calibration' on page 40).
NOTE: System must be recalibrated after restoring factory defaults.
Switching Automatic Gain Control (AGC)
on or off
The AGC can be switched on or off via the interface.
Press and hold the CAL button on the interface for > 3 seconds to switch AGC on or off. The CAL
LED on the readhead will be illuminated when AGC is active.
NOTE: The system must be calibrated before switching AGC on (see
on page 41).
