Remove applicator and, if necessary,

adhere the remaining scale manually. Apply rm nger pressure via a clean lint-free cloth along the length of the scale after application to ensure complete adhesion.

Clean scale using Renishaw scale

cleaning wipes (A-9523-4040) or a clean, dry, lint-free cloth.

Move axis to scale START position, leaving enough room for the scale

to be inserted through the applicator, as shown below.

Begin to remove the backing paper from the scale and insert scale into

the applicator up to the ‘START’ point (as shown). Ensure backing paper is routed under the splitter screw.

Apply nger pressure to the scale at the ‘START’ point, using a clean

lint-free cloth, to ensure scale end adheres well to the substrate.

RTLC40-S: Scale application

Scale applicator (A-9589-0115) is designed for use with RTLC40-S scale.

Allow scale to acclimatise to installation environment prior to installation.

Mark out the ‘START’ and ‘FINISH’ points for the scale on the axis substrate

– ensure that there is room for the optional end covers if required

(see ‘RTLC40-S: Installation drawing’).

Thoroughly clean and degrease the substrate using recommended solvents

(see 'Storage and handling'). Allow substrate to dry before applying scale.

Mount the 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.

Side mounting scale applicator

RTLC40-S: Reference mark selector and limit magnet installation

IMPORTANT: Allow 24 hours after scale application before tting magnets.

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. Limit magnets can be positioned at any user dened location along the scale, but the reference mark selector magnet should be positioned adjacent to the chosen IN-TRAC reference mark as shown.

As the QUANTiC readhead passes the reference mark selector magnet or limit switch magnet, a force of up to 0.2 N is generated between the magnet and the concentrators on the readhead. The design of the bracket should be sufciently stiff so that it is able to tolerate such force without distorting. Following the clamping instructions on the scale installation will prevent this magnetic force from disturbing the scale.

NOTE: Reference and limit magnets may creep when inuenced by magnetic materials in close proximity. In such cases, they should be held in place using an additional llet of epoxy glue or similar along the outer edge of the

magnet assembly. Optional bolted reference and limit magnets are available.

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 ‘RTLC40-S: Installation drawing’).

NOTE: External magnetic elds greater than 6mT, in the vicinity of the readhead, may cause false activation of the limit and reference sensors.

Optional bolted reference mark selector and limit magnets

RTLC40/FASTRACK: FASTRACK and scale application

During handling or installation of FASTRACK suitable gloves should be worn to protect against injury from sharp edges.

Thoroughly clean and degrease the substrate and allow to dry.

For FASTRACK location a ledge, separate straight edge(s) or dowels can be used.

Check alignment of ledge/separate straight edge(s) with respect to axis of motion

(see ‘RTLC40/FASTRACK: Installation drawing’).

If required cut FASTRACK and scale to length (separately) using guillotine (A-9589-0071) after referring to installation drawing.

Guillotine should be held securely in place, using a suitable vice or clamping method.

Feed FASTRACK or scale through the guillotine as shown, and place guillotine press block down onto the FASTRACK/scale.

Ensure the block is in the correct orientation (as shown). Whilst holding the block in place, in a smooth motion, pull down the lever to cut through the FASTRACK/scale.

Before sticking FASTRACK to the substrate bend the centre section upwards slightly using a small pair of pliers.

Remove backing liner and stick to substrate, locating against ledge/separate straight edge(s) or dowels.

Ensure complete adhesion to the substrate by applying rm nger pressure along the length of the FASTRACK from the centre outwards towards each end using a lint-free cloth if required.

NOTE: Allow the FASTRACK a minimum of 20 minutes to adhere before removing the centre section.

IMPORTANT: Wear suitable protective gloves whilst carrying out this procedure to avoid risk of cuts.

Engage centre section removal tool and with consistent forward pressure remove centre section.

If the ledge method or similar is used then the appropriate side panel on the removal tool (A-9589-0122) will need to be removed as shown.

QUANTiC linear installation guide

QUANTiC quick-start guide

This section is a quick-start guide to installing a QUANTiC readhead.

More detailed information on installing the readhead is contained on page 11 and page 12 of this installation guide.

The optional Advanced Diagnostic Tool ADTi-100* (A-6165-0100) and ADT View software† can be used to aid installation and calibration.

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 relevant installation drawing.

Connect the readhead to receiving electronics and power-up. The set-up LED on the readhead will ash.

Install and align the readhead to maximise signal strength over the full axis of travel as indicated by a Green ashing LED.

CALIBRATION

Cycle the power to the readhead to initiate the calibration routine. The LED will single ash Blue.

Move the readhead along the scale at slow speed (<100 mm/s), without passing a reference mark, until the LED starts double ashing Blue.

The system is now calibrated and ready for use. Calibration values, Automatic Gain Control (AGC) and Automatic Offset Control (AOC) status, are stored in readhead non-volatile memory at power down.

NOTE: If calibration fails (LED remains single ashing blue), restore factory defaults by obscuring the readhead optical window on power-up (see page 12). Repeat the installation and calibration routine.

For more details refer to the ‘Advanced Diagnostic Tool ADTi-100 and ADT View software quick start guide’ (M-6195-9321) and ‘Advanced Diagnostic Tool ADTi-100 and ADT View software user guide’ (M-6195-9413).

†

The software can be downloaded for free from www.renishaw.com/adt.

Reference mark

Move the readhead back and forth over the selected

reference mark until the LED stops ashing.

No reference mark

If a reference mark is not being used, the calibration routine should now be

exited by cycling the power. The LED will stop ashing.

Page 13

QUANTiC linear installation guide

Readhead mounting and alignment

Mounting brackets

The bracket must have a at mounting surface and should provide adjustment to enable conformance to the installation tolerances, allow adjustment to the rideheight of the readhead, and be sufciently stiff to prevent deection 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.

NOTE: When cleaning readhead and scale apply cleaning uid sparingly, do not soak.

To set nominal rideheight, place the appropriate spacer with the aper ture under the optical centre of the readhead to allow normal LED function during set-up procedure. RTLC40-S: green spacer, RTLC40/FASTRACK : black spacer. Adjust the readhead to achieve a ashing Green LED along the full axis of travel. The faster the ash rate, the closer it is to optimum set-up. The optional Advanced Diagnostic Tool ADTi-100 (A-6195-0100) and ADT View software can be used to optimise signal strength in challenging installations. See www.renishaw.com/adt for more information.

NOTE: When re-installing the readhead factory defaults should be restored, see page 12.

System calibration

NOTE: System calibration, restoring factory defaults, and enabling/disabling AGC functions can also be carried out using the optional ADT and ADT View software. See www.renishaw.com/adt for more information.

Ensure signal strength has been optimised along the full axis of travel, the LED will be ashing Green. Cycle the power to the readhead or connect the ‘Remote CAL’ output pin to 0 V for <3 seconds. The readhead

will then single ash Blue to indicate it is in calibration mode as detailed in ‘Readhead mounting and alignment’. The readhead will only enter calibration mode if the LED is ashing Green.

Step 1 – Incremental signal calibration

uMove the readhead along the axis at slow speed (<100 mm/s), or less than the readhead maximum speed,

whichever is slowest, ensuring it does not pass a reference mark, until the LED starts double-ashing indicating the incremental signals are now calibrated and the new settings are stored in the readhead memory.

uThe system is now ready for reference mark phasing. For systems without a reference mark, cycle the power

to the readhead or connect the ‘Remote CAL’ output pin to 0 V for < 3 seconds to exit calibration mode.

uIf the system does not automatically enter the reference mark phasing stage (LED continues single ashing)

the calibration of the incremental signals has failed. After ensuring failure is not due to overspeed (>100 mm/s),

or exceeding the readhead maximum speed, exit the calibration routine, restore factory defaults as detailed

below, 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 LED stops ashing and

remains solid Blue. The reference mark is now phased.

uThe system automatically exits the calibration routine and is ready for operation.

uAGC is automatically switched on once calibration is complete. To switch off AGC refer to the

‘Enabling/disabling AGC’ section.

uIf the LED continues double-ashing after repeatedly passing the chosen reference mark it is not being detected.

- Ensure that the correct readhead conguration is being used. Readheads can either output all reference marks or only output a reference mark where a reference selector magnet is tted depending

on the options chosen when ordering.

- Check reference mark selector magnet is tted in the correct location relative to readhead orientation, see ‘RTLC40-S installation drawing’.

Calibration routine manual exit

uTo exit the calibration routine at any stage cycle the power to the readhead or connect the ‘Remote CAL’

output pin to 0 V for <3 seconds. The LED will then stop ashing.

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:

uSwitch system off.

uObscure the readhead optical window (using the spacer supplied with the readhead ensuring the

cut-out is NOT under the optical window) or connect the ‘Remote CAL’ output pin to 0 V

uPower the readhead.

uRemove the spacer or, if using, the connection from the ‘Remote CAL’ output pin to 0 V.

uThe LED will start continuously ashing indicating factory defaults have been restored and the

readhead is in installation mode (ashing set-up LED).

uRepeat ‘Readhead set-up’ procedure.

Enabling/disabling AGC

The AGC is automatically enabled once the system has been calibrated (indicated by a Blue LED). AGC can be manually switched off by connecting the ‘Remote CAL’ output pin to 0 V for >3 seconds <10 seconds. The LED will then be solid Green.

Can’t initiate the calibration routine Signal size is <70%

Realign readhead to obtain a green ashing LED

During calibration the LED on the readhead remains single ashing Blue even after moving it along the full axis length

The system has failed to calibrate the incremental signals due to the signal strength being <70%

Exit CAL mode and restore factory defaults (see page 12)

Check system set-up and realign the readhead to obtain a Green ashing LED along the full axis of travel before recalibrating

During calibration the LED on the readhead is double ashing Blue even after moving it past the reference mark several times

The readhead is not seeing a reference mark

Ensure correct position of reference mark selector magnet

Ensure you are moving the readhead past your chosen reference mark several times

Check the readhead/selector magnet orientation

Check the readhead optical window and scale are clean and free from contamination

QUANTiC linear installation guide

Troubleshooting (continued)

Fault Cause Possible solutions

No reference mark output

Ensure you are not over-speeding the readhead during calibration mode (maximum speed <100 mm/sec)

Calibrate the system (see page 12) – If the system completes calibration mode then it has successfully seen and calibrated the reference mark If you still don’t see a reference mark then check the system wiring

– If the system does not calibrate the reference mark (LED on the readhead remains double ashing Blue) see above for possible solutions

Reference mark is not repeatable Only the chosen reference mark that has

been used in the calibration sequence is repeatable, other reference marks may not be phased

Ensure you are using the reference mark that has been calibrated for referencing your system

The readhead bracket must be stable and not allow any mechanical movement of the readhead

Clean the scale and readhead optical window and check for damage then recalibrate the system over the chosen reference mark

LED on the readhead is ashing Red over the reference mark

The reference mark is not phased

Ensure you are using the reference mark that has been calibrated for referencing your system as only this reference mark will be guaranteed to remain phased

Clean the scale and readhead optical window and check for scratches then recalibrate the system over the chosen reference mark (see page 12)

Multiple reference marks are being output

The readhead reference mark option is either option B or F, ‘All reference marks are output’

Calibrate the system ensuring both Step 1 and Step 2 are completed (see page 12)

Ensure you calibrate the reference mark used for referencing your system as only this reference mark will be guaranteed to remain phased
