TONiC FS quick-start guide

This section is a quick-start guide to installing a TONiC FS system.
More detailed information on installing the system is contained in the following sections of the installation guide.
INSTALLATION
Ensure scale, readhead optical window and mounting faces are clean and free from obstructions.
If required, ensure reference mark selector magnet is correctly positioned (see 'TONiC FS T301x readhead installation drawing' on page 6).
Plug the readhead cable into the Ti/DOP interface under the cover plate and reassemble interface. Connect to receiving electronics and power up.
Ensure Automatic Gain Control (AGC) is switched off – the CAL LED on the readhead should be off (if not, press and hold the CAL button on the interface until the CAL LED on the readhead switches off).
Install and align the readhead to maximise signal strength over the full axis of travel as indicated by the readhead and interface set-up LEDs (readhead – Green; DOP interface – ideally Blue/Purple).
CALIBRATION
Press and release the CAL button on the interface. The CAL LED on the readhead will be single-flashing.
Move the readhead along the scale at slow speed (<100 mm/s), without passing a reference mark, until the CAL LED starts double-flashing.
No reference mark
Reference mark
If a reference mark is not being used, the calibration routine should now be
Move the readhead back and forth over the selected reference mark until the
exited by pressing and releasing the CAL button.
CAL LED stops flashing and remains 'off'.
The system is now calibrated and ready for use.
For the safety function to be valid, customer commissioning tests must be performed: see 'Commissioning test' on page 3.
AGC can now be switched on if required by pressing and holding the CAL button until the CAL LED on the readhead switches on.
CAL values and AGC status are stored in readhead non-volatile memory at power down.
NOTE: If calibration fails, restore factory defaults by pressing and holding the CAL button whilst switching on. Then repeat the installation and calibration routine.
