TONiC encoder system quick-start guide
This section is a quick-start guide to installing a TONiC system. More detailed information on installing the TONiC system is contained on pages
NOTE: To meet accuracy specifications two readheads are required connected either to a DSi or to customers own electronics.
INSTALLATION
Ensure the ring, readhead optical window and mounting faces are clean
and free from obstructions.
Plug the readhead cable into the Ti interface under the cover plate and reassemble the interface
(see 'System connection'
on page 24). 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 rotation
as indicated by the readhead and interface set-up LEDs
(readhead - green; interface - ideally blue/purple).
Move to the CALIBRATION steps.
24
to
CALIBRATION
Press and release the CAL button on the interface. The CAL LED on the readhead
will be single flashing.
Rotate the axis at slow speed (< 100 mm/s), without passing a reference mark,
until the CAL LED starts double flashing.
Rotate the axis back and forth ensuring the reference mark passes the readhead until the CAL
LED stops flashing and remains 'off'.
The system is now calibrated and ready for use. 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 (see
'Restoring factory defaults'
calibration routine.
Repeat the installation and calibration process for the second readhead.
Connect the interfaces to the DSi (see
or customers output blending electronics.
