RTLF tape scale: Installation methods RTLF scale application depends upon scale length and bracket type RTLF tape scale Mounting Application (<500 mm only) (any length) Adjustable bracket Fixed mounting Readhead mounting is integral to the machine and does not allow rideheight adjustment. Ledge or dowel mounting Datum edge of readhead located against Datum edge of readhead mounted against machine axis. -
Page 8: Mounting (For Lengths <500 Mm Only)
If dowels or ledge are permanent, their maximum height above substrate is 0.6 mm. Support Clean scale using Renishaw scale cleaning wipes Install datum clamp, end covers and dowels (A-9523-4040) or a clean, dry, lint-free cloth. -

Page 13: System Connection: Top Exit Readhead
P-clip are fitted with a P-clip to ensure appropriate cable strain relief. When using Renishaw’s top exit cables ensure that the P-clip is mounted within a 50mm radius of the readhead cable exit. Minimum static bend radius of cores is 3 mm. -
Page 14: Readhead Mounting And Alignment: Methods
There is a range of tools available to assist with readhead installation depending upon the system design and these are detailed below. For more details on designing the mounting bracket and selecting the appropriate mounting tools contact your local Renishaw representative. Ensure that the scale, readhead optical window and mounting face are clean and free from obstruction. -
Page 15: Shim Kit (A-9401-0050)
Check the readhead set-up LED is flashing surface is not scratched. Green along the full axis of travel. Renishaw offer a DTi adapter (A-9401-0105) that can be used to assist with this process. Proceed with ‘System calibration’ section (see page 17). -
Page 16: Dummy Head (A-9401-0072)
It is mounted in place of the readhead directly onto the bracket. The bracket should have a shoulder to control readhead yaw. Contact your local Renishaw representative for more information on bracket design. Mount the dummy head onto the bracket using 2 off M2 × 6 screws. -
