Allow substrate to dry before applying scale. 4 Mount the appropriate scale applicator to the readhead mounting bracket using M2.5 screws. Place the shim supplied with the readhead between the applicator and substrate to set the nominal height. NOTE: Scale applicator can be mounted either way round to enable easiest orientation for scale installation. 5 Move axis to `START' of travel. 6 Begin to remove the backing paper from the scale and insert scale into the applicator up to the `START' point (as shown). Ensure backing tape is routed under the splitter screw. 7 Apply finger pressure to the scale at the `START' point, using a clean lint-free cloth, to ensure scale end adheres well to the substrate.

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. Plug the readhead cable into the Ti/TD interface under the cover plate and reassemble interface. Connect to receiving electronics and power-up. Ensure 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 travel as indicated by the readhead and interface set-up LEDs (readhead - Green; 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 If a reference mark is not being used, the calibration routine should now be exited by pressing and releasing the CAL button. The CAL LED will stop flashing. (Incremental CAL values are automatically stored) Reference mark Move the readhead back and forth over the selected reference mark until the CAL LED stops flashing and remains `off'. (Incremental and reference mark CAL values are automatically stored) 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. Then repeat the installation and calibration routine. 6 System connection Approved ESD precautions must be followed at all times during readhead and interface electrical connections. The readhead is connected to the Ti/TD interface via a small, rugged connector to allow for easy feed-through during installation. Connecting the readhead 1 Remove the cover plate as shown (2 x M2.5 hex head screws). 2 Taking care not to touch the pins, plug the connector into the socket in the interface, ensuring correct orientation as shown. Disconnecting the readhead 1 Remove the cover plate on the interface (2 x M2.5 hex head screws). 2 Gently lever the connector PCB (on the end of the cable) out of the socket. Do not pull the cable to remove the connector. 3 Place the connector in an anti-static bag. 4 Refit the cover plate. 3 Refit the cover plate ensuring the cable ferrule is located in the recess on the inside and no wires are trapped under the cover plate. NOTE: The tightening torque should be between 0.25 Nm and 0.4 Nm. TONiC RTLC-S installation guide 7 Readhead mounting and alignment Mounting brackets The bracket must have a flat mounting surface and should provide adjustment to enable conformance to the installation tolerances, allow adjustment to the rideheight of the readhead, and be sufficiently stiff to prevent deflection or vibration of the readhead during operation. Readhead set-up Ensure that the scale, readhead optical window and mounting face are clean and free from obstructions. To set nominal rideheight, place the green spacer with the aperture under the optical centre of the readhead to allow normal LED function during set-up procedure. Adjust the readhead to maximise the signal strength along the full axis of travel to achieve a Green set-up LED on the readhead (>70% signal). If a digital Ti/TD interface is used, aim for a Blue LED on the interface NOTE: The readhead should be installed and set-up with the AGC switched off (CAL LED off). When reinstalling factory defaults should be restored.

For accuracy and ease of positioning of reference mark selector and limit magnets, the applicator tool (A-9653-0201) should be used. The magnet should be attached to the applicator tool as shown below. Limit magnets can be positioned at any user defined location along the scale, but the reference mark selector magnet should be positioned adjacent to the chosen IN-TRAC reference mark as shown below. NOTE: Reference and limit magnets may creep when influenced by magnetic materials in close proximity. In such cases, they should be held in place using an additional fillet of epoxy glue or similar along the outer edge of the magnet assembly. Optional bolted reference and limit magnets are available, refer to `RTLC-S installation drawing' for details. Applicator tool (A-9653-0201) P limit magnet Remove self-adhesive backing paper Correct position of reference selector for readhead orientation shown Limit trigger point The limit output is nominally asserted when the readhead limit switch sensor passes the limit magnet leading edge, but can trigger up to 3 mm before that edge. (See `RTLC-S installation drawing') Datum clamp (A-9585-0028) The datum clamp fixes the RTLC-S scale rigidly to the substrate at the location chosen. The metrology of the system may be compromised if the datum clamp is not used. The datum clamp does not need to be fitted adjacent to a reference mark. It can be positioned anywhere along the axis depending upon the customers' requirements. 1 Place the datum clamp with cut-out against the scale at the chosen location. 2 Place a small amount of adhesive (Loctite® 435TM) in the cut-out on the datum clamp, ensuring none of the adhesive wicks onto the scale surface. Dispensing tips P-TL50-0209 are available. IN-TRAC reference mark Q limit magnet Ensure the adhesive wicks along the entire length of cut-out. 8 System calibration Calibration is an essential operation that completes readhead set-up, with the optimum incremental and reference mark signal settings stored in the readhead's non-volatile memory. Before system calibration: u Clean the scale and readhead optical window (contamination around the reference mark may result in reference mark dephasing). u If reinstalling restore factory defaults. u Ensure Automatic Gain Control is switched off (CAL LED on readhead is not illuminated) u Maximise the signal strength along full axis of travel. NOTE: CAL routine maximum speed <100 mm/s (all Ti/TD interface models). TD interface can be calibrated in either resolution. Step 1 Incremental signal calibration u Press the CAL button on the end of the interface for <2 seconds using a 2 mm allen key or similar tool. WARNING! Activating the CAL switch only requires 2.5 N force. Applying excess force may permanently damage the switch. u The CAL LED will now periodically single-flash to indicate that it is in incremental signal calibration routine. u Move the readhead along the axis, ensuring you do not pass the selected reference mark until the CAL LED starts double-flashing. This indicates the incremental signal is now calibrated and the new settings are stored in the readhead memory. u The system is now ready for reference mark phasing. u For systems without reference mark, go to `Calibration routine - manual exit' u If the system does not automatically enter the reference mark phasing stage (no double-flashing of the CAL LED) the calibration of the incremental signals has failed. After ensuring failure is not due to overspeed (>100 mm/s), exit the calibration routine, restore factory defaults and check the readhead installation and system cleanliness before repeating the calibration routine. Step 2 Reference mark phasing u 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. NOTE: Only the chosen reference mark that has been used in the calibration routine is guaranteed to remain phased. u The system automatically exits the CAL routine and is ready for operation. u 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. Calibration routine manual exit u The calibration routine can be exited at any stage. To exit the calibration routine press the CAL button. On successful exit the CAL button will stop flashing. CAL LED Single flashing Double flashing Off (auto-complete) Settings stored None, restore factory defaults and recalibrate Incremental only Incremental and reference mark Restoring factory defaults When realigning the readhead, reinstalling the system or in the case of continued calibration failure, factory defaults should be restored. To restore factory defaults: u Switch system off. u 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. TONiC RTLC-S installation guide u Release CAL button. u Check the `Readhead mounting/installation' and recalibrate the system. NOTE: System must be recalibrated after restoring factory defaults. Switching Automatic Gain Control (AGC) on or off AGC can be switched on or off via the interface. u 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.
