Scale application
The scale applicator A-9541-0124 is designed specically for use with the RGH25F readheads
and RGS20-S scale. Use applicator A-9541-0305 when installing RGS20-P scale.
1 Allow scale to acclimatize to installation environment prior to installation.
2Thoroughly clean and degrease the substrate using recommended solvents (see 'Storage and handling').
Allow substrate to dry before applying scale.
3 Mark out ‘START’ and ‘FINISH’ points for the scale on the axis substrate. Ensure that there is room for the
end clamps (see ‘RGS20 scale installation drawing’).
4Mount 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 close to scale start position, leaving enough room for the scale to be inserted through the
applicator as shown below.
6Begin 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 nger pressure to the scale at the ‘START’ point,
using a clean lint-free cloth, to ensure scale end
adheres well to substrate.
End clamps
A-9523-4015 is an end clamp kit designed to be used with Renishaw RGS scale.
IMPORTANT: End clamps should be used to ensure positional stability of the scale and
reference mark repeatability.
NOTE: End clamps can be mounted before or after readhead installation.
Ensure that excess glue is wiped away from scale
as it may affect the readhead signal level.
3The end clamp features two small regions
of contact adhesive. These will temporarily
hold the end clamp in position while the glue
cures. Remove the backing tape
from either side.
15 mm
1Remove the lacquer coating from the last
15 mm of each end of the scale with a knife
and clean with one of the recommended
solvents (see ‘Storage and handling’).
4Immediately position end clamp over the
end of the scale.
Allow 24 hours at 20 °C for full cure.
Thoroughly mix up a sachet of glue
(A-9531-0342) and apply a small amount
to the underside of the end clamp.
9 Remove applicator and, if necessary, adhere 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.
10 Clean the scale using Renishaw scale wipes (A-9523-4040) or a clean, dry, lint-free cloth.
11 Fit end clamps (see ‘End clamps’ section).
12 Allow 24 hours for complete adhesion of scale before tting the reference mark or limit magnet.

RGH25F RGS20 installation guide
For reliable operation, the SET UP LED should be at least Green,
ideally blue or purple when readhead is moved along the full axis travel.
Readhead mounting and alignment
System description
The RGH25F encoder system consists of a common readhead in standard or UHV compatible form, coupled to
the interface, which gives accurate, industry standard outputs. There are 10 versions of the REF interface, offering
digital resolutions of 5 μm to 5 nm, and an analogue version giving 1 Vpp output. The digital REF interfaces are
available with a variety of different clocked outputs, each interface option having a different maximum speed and
minimum customer counter clock frequency, ranging from 1 to 50 MHz.
Mounting brackets
The bracket must have a at mounting surface, 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. For easier installation, adjust the roll and yaw of the bracket with respect to the axis of readhead
travel before the RGH25F is attached. This can be done with a clock gauge and a precision square.
Readhead set-up
To set nominal rideheight, position readhead spacer with ‘L’shaped aperture under the optical centre of the
readhead to allow normal LED function during set-up procedure. Ensure that the scale, readhead optical window
and mounting face are clean and free from obstructions.
NOTE: Ensure readhead xing screws are tightened to 0.5 Nm-0.7 Nm.

REF interface features
Self-tuning active correction
The REF interface actively corrects for input signal imperfections to optimise system accuracy.
Corrections are made for the following:
Automatic Offset Control (AOC) – adjusts offset independently for the sine and cosine signals
Automatic Gain Control (AGC) – ensures consistent 1 Vpp signal amplitude
Automatic Balance Control (ABC) – adjusts the gain to equalise the sine and cosine signals
These correction mechanisms operate over the full working speed range of the readhead. The user can
disable/enable the AGC by depressing the CALIBRATE button for greater than 3 seconds.
REF Interface LED diagnostics
The REF interface SETUP LED provides visual feedback of signal strength, error condition and reference
mark phasing, for setup and diagnostic use.

*Alarm output will take the form of 3-state or line driven differential E signal depending on interface conguration.
Also some congurations do not output overspeed alarm. See Interface part numbers in the RGH25F encoder system
data sheet for details.
System calibration

Reference mark set-up
To ensure unidirectional repeatability, the reference mark requires phasing with the scale in the direction
of normal datuming operation.
A reference pulse is output in both directions, but repeatabilty is guaranteed only in the
phased direction.
Ensure readhead is set up correctly with a green LED indication over the full length of travel and that
the reference mark actuator is fitted correctly.
NOTE: It is recommended that a datum procedure is performed as part of any power-up sequence to
ensure the correct datum position is recorded.
NOTE: Reference mark output is synchronised with the incremental channels, giving unit of resolution
pulse width.
Phasing procedure
The readhead must be moved over the reference mark in the direction to be used for the datuming
operation. The reference mark is phased correctly when the set-up LED flashes red for 0.25 seconds.
If it flashes orange or goes blank, the reference mark adjuster screw should be turned anti-clockwise
by 1
/
8turn and the procedure repeated until a red flash is obtained.
Red Orange Blank
Limit switch
A limit switch signal is output when the readhead sensor passes over the magnetic actuator.
NOTE: RGH25F readheads are available with reference mark or limit switch detection.
Select output at order.
SET UP LED colour at

NOTE: Reference mark ashes only
occur up to 100 mm/s traverse speed.

Alarm output
The REF interface asserts the alarm output (E) for the following conditions:-
Incremental signal level below 20%
Incremental signal level above 135%
Readhead speed in excess of specication
Signal offset compensation of sine and cosine excessive
Signal balance compensation excessive
System installation/calibration
The calibration procedure is required to optimise the gain, balance and offset of the analogue input
signals in the REF interface. These settings are then stored and recalled for initial use at startup.
To calibrate the system, the following sequence should be carried out:
uPrior to calibration, AGC should be off. To switch AGC on or off, the CALIBRATE button should
be pressed for more than 3 seconds. When AGC is on, the CAL/AGC LED will be on and when
AGC is off, the CAL/AGC LED will be off.
uInstall the readhead according to the instructions in the ‘Readhead mounting and alignment’ section.
uEnter the calibration routine by pressing the CALIBRATE button momentarily. The calibration routine
is indicated by slow ashing of the CAL/AGC LED.
u Traverse the readhead slowly past the scale until the CAL/AGC LED stops ashing. The calibration
cycle is now complete.
If calibration fails, the CAL/AGC LED will ash quickly instead of switching off. If this happens the
CALIBRATE button should be pressed momentarily to exit the calibration routine. The calibration procedure
should then be re-tried.
If the unit continues to fail calibration, factory default settings should be restored by powering down, then
pressing the CALIBRATE button as power is re-applied. The calibration procedure should then be repeated.
NOTE: To exit the calibration routine at any time, the CALIBRATE button should be pressed momentarily.
If tted, the reference mark should be phased (see reference mark set-up)
