Equipment required for installing the RTLA30-S scale

Required parts:

• Appropriate length of RTLA30-S scale (see ‘RTLA30-S scale installation drawing’ on page 10)
• Datum clamp (A-9585-0028)
• Loctite® 435 ™ (P-AD03-0012)
• Lint-free cloth
• Appropriate cleaning solvents (see ‘Storage and handling’ on page 6)
• RTLA30-S scale applicator (A-9589-0095)
• 2 × M3 screws

Optional parts:

• End cover kit (A-9585-0035)
• Renishaw scale wipes (A-9523-4040)
• Loctite® 435™ dispensing tip (P-TL50-0209)
• Guillotine (A-9589-0071) or shears (A-9589-0133) for cutting RTLA30-S to length required

Cutting the RTLA30-S scale
If required cut the RTLA30-S scale to length using the guillotine or shears.
Using the guillotine
The guillotine should be held securely in place, using a suitable vice or clamping method.
Once secured, feed the RTLA30-S scale through the guillotine as shown, and place guillotine press block down onto the scale.
NOTE: Ensure the block is in the correct orientation (as shown below).
Guillotine press block orientation when cutting the RTLA30-S scale

Whilst holding the block in place, in a smooth motion, pull down the lever to cut through the scale.

Using the shears
Feed the RTLA30-S scale through the middle apperture on the shears (as shown below).

Hold the scale in place and close the shears in a smooth motion to cut through the scale.

Applying the RTLA30-S scale

1. Allow the scale to acclimatise to the installation environment prior to installation.

2. Mark out the start position for the scale on the axis substrate – ensure that there is room for the optional end covers if required (see ‘RTLA30-S scale installation drawing’ on page 10).

3. Thoroughly clean and degrease the substrate using recommended solvents (see ‘Storage and handling’ on page 6). Allow the substrate to dry before applying the scale.

4. Mount the scale applicator to the readhead mounting bracket. Place the shim supplied with the readhead between the applicator and the substrate to set the nominal height.
   NOTE: The scale applicator can be mounted either way round to enable easiest orientation for the scale installation.

5. Move the axis to the start of travel leaving enough room for the scale to be inserted through the applicator, as shown below.

6. Begin to remove the backing paper from the scale and insert the scale into the applicator up to the start position. Ensure the backing tape is routed under the splitter screw.

7. Apply firm finger pressure via a clean, dry, lint-free cloth to ensure the scale end adheres wellto the substrate.

8. Slowly and smoothly move the applicator through the entire axis of travel. Ensure the backing paper is pulled manually from the scale and does not catch under the applicator.
   

9. During installation ensure the scale is adhered to the substrate using light finger pressure.

10. Remove the applicator and, if necessary, adhere the remaining scale manually.

11. Apply firm finger pressure via a clean lint-free cloth along the length of the scale after application to ensure complete adhesion.

12. Clean the scale using Renishaw scale cleaning wipes or a clean, dry, lint-free cloth.

13. Fit the end covers if required (see ‘Fitting the end covers’ on page 14).

14. Allow 24 hours for complete adhesion of the scale before fitting the datum clamp (see ‘Fitting the datum clamp’ on page 14).

Fitting the end covers
The end cover kit is designed to be used with the RTLA30-S scale to provide protection for exposed scale ends.
NOTE: The end covers are optional and can be fitted before or after readhead installation.

1. Remove the backing tape from the adhesive tape on the back of the end cover.
2. Align markers on the edges of the end cover with the end of the scale and place the end cover over the scale.
   NOTE: There will be a gap between the end of the scale and the adhesive tape on the end cover.

Fitting the datum clamp
The datum clamp fixes the RTLA30-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.
It can be positioned anywhere along the axis depending upon the customers’ requirements.

1. Remove the backing paper from the datum clamp.
2. Place the datum clamp with cut-out against the scale at the chosen location.
3. Place a small amount of adhesive (Loctite) in the cut-out on the datum clamp, ensuring none of the adhesive wicks onto the scale surface. Dispensing tips for the adhesive are available.
   

RESOLUTE 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.
NOTE: When cleaning the readhead and scale apply cleaning fluid sparingly, do not soak.
To set nominal rideheight, place the blue spacer with the aperture under the optical centre of the readhead to allow normal LED function during set-up procedure. Adjust the readhead to maximize the signal strength along the full axis of travel to achieve a green  or blue LED.
NOTES:

• Flashing of the set-up LED indicates scale reading error. The flashing state is latched for some serial protocols; remove power to reset.
• The optional Advanced Diagnostic Tool ADTa-100 can be used to aid installation. The ADTa-100 and ADT View software are only compatible with RESOLUTE readheads showing the 1 (A-6525-0100) and ADT View software 2 mark. Contact your local  Renishaw representative for other readhead compatibility.
  1 For more details refer to the Advanced Diagnostic Tools and ADT View software User guide (Renishaw part no. M-6195-9413).
  2 The software can be downloaded for free from www.renishaw.com/adt.
  3 The LED is activated regardless of whether the corresponding messages have been reconfigured.
  4 The colour depends upon the LED status when component recognition is activated via p0144=1.

Electrical connections

Grounding and shielding 1
Single-shielded cable 2

IMPORTANT:

• The shield should be connected to the machine earth (Field ground).
• If the connector is modified or replaced, the customer must ensure both 0 V cores (white and green) are connected to 0 V.

Double-shielded cable 2

IMPORTANT:

• The outer shield should be connected to the machine earth (Field ground). The inner shield should be connected to 0 V at customer electronics only. Care should be taken to ensure that the inner and outer shields are insulated from each other.
• If the connector is modified or replaced, the customer must ensure both 0 V cores (white and green) are connected to 0 V.

Grounding and shielding – RESOLUTE Siemens DRIVE-CLiQ systems only

Single-shielded cable

Double-shielded cable

IMPORTANT: If reterminating double-shielded readhead cable, care should be taken to ensure that the inner and outer shields are insulated from each other. If the inner and outer shields are connected together, this will cause a short between 0 V and earth,  which could cause electrical noise issues.

CAUTION: The RESOLUTE encoder system has been designed to the relevant EMC standards, but must be correctly integrated to achieve EMC compliance. In particular, attention to shielding arrangements is essential.

1. Current consumption figures refer to terminated RESOLUTE systems. Renishaw encoder systems must be powered from a 5 Vdc supply complying with the requirements for SELV of standard IEC 60950-1.
2. The Renishaw DRIVE-CLiQ interface must be powered from a 24 Vdc supply complying with the requirements for SELV of standard IEC 60950-1.
3. This is the worst case figure that is correct for the slowest communications clock rates. For faster clock rates, the maximum acceleration of scale with respect to the readhead can be higher. For more details, contact your local Renishaw representative.

RTLA30-S scale specifications

Standards
Material| Hardened and tempered martensitic stainless steel fitted with a self-adhesive backing tape
Mass| 12.9 g/m
Coefficient of thermal expansion (at 20 °C)| 10.1 ±0.2 µm/m/°C
Installation temperature| +15 °C to +35 °C
Datum fixing| Datum clamp (A-9585-0028) secured with Loctite® 435™ (P-AD03-0012)

Maximum length
The maximum scale length is determined by the readhead resolution and the number of position bits in the serial word. For RESOLUTE readheads with fine resolution and short word length, the maximum scale length will be limited accordingly. Conversely, coarser resolutions or longer word lengths enable the use of longer scale lengths.
