Safety
Information to the user
The RTS is supplied with two non-rechargeable AA
alkaline batteries. Once the charge in these batteries
is depleted, please dispose of them in accordance
with your local environmental and safety laws. Do
not attempt to recharge these batteries.
Please ensure replacement batteries are of the
correct type and are fitted with the correct polarity
in accordance with the instructions in this manual,
and as indicated on the product. For specific
battery operating, safety and disposal guidelines,
please refer to the battery manufacturers'
literature.
• Ensure that all batteries are inserted with
the correct polarity.
• Do not store batteries in direct sunlight or
rain.
• Do not heat or dispose of batteries in a fire.
• Avoid forced discharge of the batteries.
Under certain circumstances, the probe signal
may falsely indicate a probe seated condition. Do
not rely on probe signals to halt the movement of
the machine.
Information to the equipment installer
All Renishaw equipment is designed to comply
with the relevant EC and FCC regulatory
requirements. It is the responsibility of the
equipment installer to ensure that the following
guidelines are adhered to, in order for the product
to function in accordance with these regulations:
• any interface MUST be installed in a
position away from any potential sources
of electrical noise, i.e. power transformers,
servo drives etc;
• all 0V/ground connections should be
connected to the machine "star point" (the
"star point" is a single point return for all
equipment ground and screen cables)
This is very important and failure to adhere
to this can cause a potential difference
between grounds;
.
Before you begin
1.5
• Do not short-circuit the batteries.
• Do not disassemble, pierce, deform or apply
excessive pressure to the batteries.
• Do not swallow the batteries.
• Keep the batteries out of the reach of
children.
• Do not get batteries wet.
If a battery is damaged, exercise caution when
handling it.
The RTS has a glass window. Handle with care if
broken to avoid injury.
Information to the machine supplier/
installer
It is the machine supplier's responsibility to ensure
that the user is made aware of any hazards
involved in operation, including those mentioned
in Renishaw product literature, and to ensure
that adequate guards and safety interlocks are
provided.
• all screens must be connected as outlined in
the user instructions;
• cables must not be routed alongside high
current sources, i.e. motor power supply
cables etc, or be near high speed data lines;
• cable lengths should always be kept to a
minimum.
Equipment operation
If this equipment is used in a manner not specified
by the manufacturer, the protection provided by
the equipment may be impaired.

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.
Operation

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.
