TONiC 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 14 to 18 of this installation guide. INSTALLATION Ensure RESM20 ring, readhead optical window and mounting faces are clean and free from obstructions. Plug the readhead cable into the Ti/TD interface under the cover plate and reassemble interface.
System connection Approved ESD precautions must be followed at all times during readhead and interface electrical connections. The readhead is connected to the Disconnecting the readhead Ti/TD interface via a small, rugged connector to allow for easy feed-through during installation. Remove the cover plate on the interface (2 x M2.5 hex head screws).

System calibration Calibration is an essential operation that completes readhead set-up, with the optimum incremental and Step 2 – Reference mark phasing reference mark signal settings stored in the readhead’s non-volatile memory. Move the readhead back and forth over the selected reference mark until the CAL LED stops Before system calibration: flashing and remains off.
Restoring factory defaults When re-installing the system, or in the case of continued calibration failure, factory defaults should be restored. To restore factory defaults: Switch system off. 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. Release CAL button.
