RTS basics
2.1
Introduction
The RTS is a tool setter with radio transmission
suitable for use on small to large machining
centres, or where line-of-sight between probe and
receiver is difficult to achieve.
The RTS forms part of Renishaw’s family of new
generation radio transmission probes. It has been
designed to comply with worldwide standards
and operates in the 2.4 GHz band. It delivers
interference-free transmission through the use of
FHSS (Frequency Hopping Spread Spectrum).
This allows many systems to operate in the same
machine shop without risk of cross-interference.
All RTS settings are configured using Trigger
Logic™. This technique enables the user to
review and subsequently change probe settings
by deflecting the stylus whilst observing the LED
indication.
System interface
The RMI and RMI-Q are combined antenna,
interface and receiver units used to communicate
between the RTS and the machine controller.
Trigger Logic™
All RTS settings are configured using the Trigger
Logic™ technique.
Trigger Logic™ (see Section 4, "Trigger
Logic™") is a method that allows the user to
view and select all available mode settings in
order to customise a probe to suit a specific
application. Trigger Logic™ is activated by battery
insertion and uses a sequence of stylus deflection
(triggering) to systematically lead the user through
the available choices to allow selection of the
required mode options.
Getting started
A multicolour LED provides visual indication of
selected probe states:
• trigger filter setting;
• tool setter status - triggered or seated;
• battery condition.
Batteries are inserted or removed as shown in
Section 5, "Maintenance" page 5.2.
On insertion of the batteries, the LED will begin
to flash (see Section 4, "Trigger Logic™" page
4.1).
Current probe settings can be reviewed by
simply removing the batteries for a minimum of
5 seconds, and then replacing them to activate
the Trigger Logic™ review sequence.
Modes of operation
The RTS can be in one of three modes:
Standby mode: where the RTS is awaiting a
switch-on signal.
Operational mode: activated by the switch-on
method described on the next page, the RTS is
ready for use.
Configuration mode: where Trigger Logic™ may
be used to configure the following probe settings.
RTS basics
2.2
RTS installation guide
Configurable settings
Enhanced trigger filter
Probes subjected to high levels of vibration or
shock loads may trigger without having been
contacted. The enhanced trigger filter improves
the probe’s resistance to these effects.
When the filter is enabled, a constant nominal
6.7 ms delay is introduced to the probe output.
It may be necessary to reduce the approach
speed to allow for the increased stylus overtravel
during the extended time delay. The RTS is factory
set to Enhanced trigger filter off.
Acquisition mode
System set-up is achieved using Trigger Logic™
and powering on the RMI or RMI-Q.
Partnering is only required during initial system
set-up. Further partnering is only required if either
the RTS or RMI/RMI-Q is changed.
Partnering will not be lost by reconfiguration of
probe settings or when changing batteries.
Partnering can take place anywhere within the
operating envelope.
Switch-on
When the RTS is used with an RMI the turn-on
time is 1.0 second. When the RTS is used with an
RMI-Q the turn-on time can be configured, in the
RMI-Q, to either 0.5 seconds or 1.0 second. For
best battery life, select 1.0 second turn-on time.
A timer automatically switches the probe off
90 minutes after the last trigger if not turned
off by an M code.
NOTE: After being switched on, the RTS must be
on for 1.0 second minimum before being switched
off.

cutting direction. Renishaw tool setting software
calculates speeds and feeds automatically using
the following information.
First touch – machine spindle rev/min
Rev/min for the first move against the probe
stylus:
Diameters below 24 mm, 800 rev/min is used.
Diameters from 24 mm to 127 mm, rev/min is
calculated using a surface speed of 60 m/min
(197 ft/min).
Diameters above 127 mm, 150 rev/min is used.
RTS basics
2.3
The tool is driven in the machine Z axis for tool
length measurements and broken tool detection.
Rotating tools are set in the machine’s X and Y
axes for tool radius offsets.
Screw adjusters allow the stylus to be aligned with
the machine’s axes.
Software routines
Software routines for tool setting are available
from Renishaw for various machine controllers
and are described in data sheet H-2000-2289.
In addition, data sheet H-2000-2298 lists available
Renishaw software programs. Both data sheets
can be downloaded from www.renishaw.com/
inspectionplus.
First touch – machine feed rate
The feedrate (f) is calculated as follows:
f = 0.16 × rev/min f units mm/min (diameter set)
f = 0.12 × rev/min f units mm/min (length set)
Second touch – machine feed rate
800 rev/min, 4 mm/min (0.16 in/min) feedrate.
Achievable set-up tolerances
The tolerances to which tools can be set depend
upon the flatness and parallelism of the stylus tip
setting. A value of 5 µm (0.0002 in) front to back
and side to side is easily achievable over the flat
portion of the stylus tip, and 5 µm (0.0002 in)
parallelism is easily achievable with the axes of a
square tip stylus. This setting accuracy is sufficient
for the majority of tool setting applications.

Radio transmission does not require line-ofsight between the probe and transmitter and will
pass through very small gaps and machine tool
windows. This allows easy installation, either
inside or outside the machine enclosure, so long
as the probe and transmitter are kept within the
performance envelope specified and that the RMI
signal LED remains on at all times.
Coolant and swarf residue accumulating on the
RTS and RMI may have a detrimental effect
on transmission performance. Wipe clean as
often as is necessary to maintain unrestricted
transmission.
When in operation, do not touch either the RMI
cover or the RTS glass window with your hand as
this can also affect transmission performance.
Some reduction in range may result when
operating in temperatures of 0 °C to +5 °C
(+32 °F to +41 °F) and +50 °C to +60 °C

RTS - RMI/RMI-Q positioning
The probe system should be positioned so that
the optimum range can be achieved over the full
travel of the machine's axes. Always face the front
cover of the RMI/RMI-Q in the general direction
of the machining area and the tool magazine,
ensuring both are within the performance
envelope shown below. To assist in finding the
optimum position of the RMI/RMI-Q, the signal
quality is displayed on an RMI/RMI-Q signal LED.
Ensure that the signal LED indicates a green or
yellow (good) signal strength when the RTS is
operating or in stand-by mode (see following note
regarding 'hibernate mode').

NOTE: RMI/RMI-Q installation with RTS.
RTS has a built-in hibernate mode (battery saving
mode) that saves battery life when the RMI/RMI-Q
is unpowered. The RTS goes into hibernate mode
30 seconds after the RMI/RMI-Q is unpowered
(or the RTS is out of range). When in hibernate
mode, the RTS checks for a powered RMI/RMI-Q
every 30 seconds. If found, the RTS goes from
hibernate mode to stand-by mode, ready for an
M code. If the RTS goes out of range, for example
if the RTS is fitted to a pallet which is removed
from the machine, once the RTS is back in range
the system will automatically re-synchronise
within 30 seconds (worst case). Allowance must
be made within the machine controller program for
this.
Performance envelope
The RTS and RMI/RMI-Q must be within each
other's performance envelope as shown below.
The performance envelope shows line-of-sight
performance, however radio transmission does
not require this providing a reflected path (of less
than 15 m (49.2 ft)) is available.

mechanism from damage in the event of
excessive stylus overtravel or a collision.
Captive link
In the event of the break stem breaking, the
captive link ties the stylus to the probe, which
prevents the stylus falling into the machine.
NOTE: Always hold the support bar in position

Dowel pins (shown on page 2.4)
NOTE: A smaller washer should be fitted for a
smaller bolt by disassembling and separating the
base plates.
Two locating pins (supplied in the tool kit) may be
fitted on installations where there is a requirement
to remove and remount the tool setter.
To fit the dowel pins, drill two holes in the machine
table to correspond with the two probe base holes.
Place the dowel pins in the holes and refit the
probe base.
Stylus level setting
The top surface of the stylus must be set level,
front to back and side to side.
Side to side level adjustment
Side to side level adjustment is obtained by
alternately adjusting the grub screws provided,
which causes the probe module to rotate and
change the stylus level setting.
When a level stylus surface is obtained, tighten
the grub screws.

Calibrating the RTS
Why calibrate a probe?
A probe is just one component of the
measurement system which communicates with
the machine tool. Each part of the system can
introduce a constant difference between the
position that the stylus touches, and the position
that is reported to the machine. If the probe is
not calibrated, this difference will appear as an
inaccuracy in the measurement. Calibration of the
probe allows the probing software to compensate
for this difference.
During normal use, the difference between the
touch position and the reported position does not
change but it is important that you calibrate your
probe in the following circumstances:
• when a probe system is to be used for the
first time;
The calibration values are stored in macro
variables for computation of the tool size during
tool setting cycles.
Values obtained are axis trigger positions
(in machine co-ordinates). Any errors due to
machine and probe triggering characteristics
are automatically calibrated out in this way.
These values are the electronic trigger positions
under dynamic operating conditions, and
not necessarily the true physical stylus face
positions.
NOTE:
Poor repeatability of probe trigger point values
indicates that either the probe/stylus assembly
is loose or a machine/probe fault exists. Further
investigation is required.
System
installation
3.13
• when a new stylus is fitted to the probe;
• when it is suspected that the stylus has
become distorted or that the probe has
crashed;
• at regular intervals to compensate for
mechanical changes of your machine tool.
When your probe is assembled and mounted
on the machine table, it is necessary to align
the stylus faces with the machine axes to avoid
probing errors when setting tools. It is worth taking
care with this operation – you should try to get the
faces aligned to within 0.010 mm (0.0004 in)
for normal use. This is achieved by manually
adjusting the stylus with the adjusting screws
provided, and using a suitable instrument such as
a DTI clock mounted in the machine spindle.
When the probe has been correctly set up on
the machine, it is time to calibrate the probe.
Calibration cycles are available from Renishaw
for this task. The purpose is to establish the probe
stylus measuring face trigger point values under
normal measuring conditions.
Calibration should be run at the same speed as
probing.

NOTES:
Due to the nature of Lithium Thionyl Chloride batteries, if a 'low battery' LED sequence is ignored
or overlooked, then it is possible for the following sequence of events to occur:
1. When the probe is active, the batteries discharge until battery power becomes too low for the
probe to operate correctly.
2. The probe stops functioning, but then re-activates as the batteries recover sufficiently to
provide the probe with power.
3. The probe begins to run through the LED review sequence, see page 4.1.
4. Again, the batteries discharge and the probe ceases to function.
5. Again, the batteries recover sufficiently to provide the probe with power and the sequence
repeats itself.

Routine maintenance
The probe is a precision tool and must be
handled with care.
Maintenance
5.4
Ensure the probe is firmly secured to its
mounting.
The probe requires minimal maintenance as it is
designed to operate as a permanent fixture on
CNC machining centres, where it is subject to a
hot chip and coolant environment.
1. Do not allow excessive waste material to
build up around the probe.
2 Swarf accumulating on the transmission
window will have a detrimental effect on
transmission performance, see page 5.1.
3. Keep all electrical connections clean.
4. The probe mechanism is protected by an
outer metal eyelid seal and an inner flexible
diaphragm seal.
Approximately once a month, inspect the probe
inner diaphragm seal, see page 5.5. If it is
pierced or damaged please contact Renishaw.

3. Wash inside the probe, using clean coolant.
(DO NOT use sharp objects to clean out
debris).
1. Remove the stylus/break stem assembly
using the 5 mm AF spanner.
2. Use a 24 mm or 15/16 in spanner to remove
the probe’s front cover. This will expose
the metal eyelid seal, spring and the inner
diaphragm seal. Remove the metal eyelid
and spring.
