2.12.1
Introduction
Welcome to the RLP40 job set-up and inspection
probe. At only 40 mm diameter, this compact
probe sets industry standards for functionality,
reliability and robustness in the harshest of
machine tool environments.
RMP40 forms part of Renishaw's family of new
generation radio transmission probes, It is ideally
suited to large machining centres, where line-of-
sight between probe and receiver is difficult to
achieve or where Z travel is limited.
RLP40 complies with FCC regulations 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 RLP40 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
display.
Configurable settings are:
• Radio on / Radio off
• Radio on / Timer off
• Spin on / Spin off
• Spin on / Timer off
• Filter on / Filter off
• Multiple probe mode on / multiple probe
mode off
Getting started
Three multicolour LEDs provide visual indication
of selected probe settings.
For example:
• Switch-on and switch-off methods
• Probe status - triggered or seated
• Battery condition
Batteries are inserted or removed as shown (see
‘RLP40 batteries’ for further information).
On insertion of batteries, the LEDs will begin to
flash (see ‘Reviewing current probe settings’ for
further information).
System interface
The RMI integrated interface/receiver is used to
communicate between the RLP40 probe and the
machine control.

2.2
RLP40 basics
Trigger Logic™
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 subsequent
stylus deflection. A sequence of stylus deflection
(triggering) is then used to systematically lead
the user through the available choices to allow
selection of the required mode options.
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 RLP40 probe can be in one of three modes:
Standby mode: where the probe is awaiting a
switch on signal.
Operational mode: activated by one of the switch
on methods described on this page. In this mode
the RLP40 is ready for use.
Configuration mode: where Trigger Logic™ may
be used to configure the following probe settings.
Configurable settings
Switch on/switch off methods
The following switch on/switch off options are
user-configurable.
1. Radio on/Radio off
2. Radio on/Timer off
3. Spin on/Spin off
4. Spin on/Timer off
Enhanced trigger filter
Probes subjected to high levels of vibration or
shock loads may output signals without having
contacted any surface. The enhanced trigger filter
improves the probes resistance to these effects.
When the filter is enabled, a constant 10 ms delay
is introduced to the probe output.
The RLP40 is factory set to trigger filter off.
NOTE: It may be necessary to reduce the probe
approach speed to allow for the increased stylus
overtravel during the extended time delay.
2.3
RLP40 basics
RLP40 switch on method
Switch on options are configurable
RLP40 switch off method
Switch off options are configurable
Switch on time
Radio on
Radio switch on is commanded by
machine input.
Radio off
Radio switch off is commanded by
machine input. A timer automatically
switches the probe off 90 minutes
after the last trigger if it is not turned
off by machine input.
Timer off (timeout)
Timeout will occur 12, 33 or 134
seconds (user configurable) after the
last probe trigger or reseat.
1 second maximum
Note: This assumes
a good radio
communication link.
In a poor RF
environment this may
rise to a maximum of
3 seconds.
Spin on
Spin at 500 rev/min for 1 second
minimum (6 seconds maximum).
Spin off
Spin at 500 rev/min for 1 second
minimum (6 seconds maximum).
A timer automatically switches the
probe off 90 minutes after the last
trigger if it is not spun.
Timer off (timeout)
Timeout will occur 12, 33 or 134
seconds (user configurable) after the
last probe trigger or reseat.
2 seconds maximum.
Note: The 2 seconds
starts from the
moment the spindle
reaches 500 rev/min.
NOTE: After being switched on, the RLP40 must be on for 1 second minimum (the RLP40 must be
spun down before it can be spun off again) before being switched off.
RLP40 installation guide
2.4
RLP40 basics
Multiple probe mode
The RLP40 can be configured, using Trigger
Logic™, to allow multiple radio probes to be used
with a single RMI.
NOTES:
The 'radio on' switch on method cannot be used
in multiple probe mode. Multiple probe mode will
not appear as an option if the 'radio on' option has
been selected.
RLP40 probes which are set to 'multiple probe
mode on' can coexist alongside any number of
RLP40 probes set to 'mode off'.
To allow multiple radio probes to work in close
proximity, and with a single RMI, 16 choices of
'mode on' colours are available, each representing
a different machine tool installation. The colour
choices available are as shown on page 4.2.
All probes operating with a single RMI must be set
to the same 'mode on' colour choice; any multiple
probes located on adjacent machines must all be
set to an alternative 'mode on' colour choice.
Only one probe per 'mode on' colour choice needs
to be partnered with the RMI as, by configuring
multiple probes to a single 'mode on' colour
choice, all probes using this 'mode on' colour
choice will have the same identity. The probe to be
partnered is partnered after selecting the 'multiple
probe mode' setting and choosing the 'mode
on' option. See 'Changing the probe settings' in
Section 4, "Trigger Logic™".
There is no limit to the number of probes that can
be used with a single RMI so long as they all have
the same 'mode on' colour choice.
All RLP40 probes are factory set to 'mode off'.
The addition of any further probe(s) into a single
probe installation will require that all probes are
reconfigured to the same 'mode on' colour choice
and that one of the probes is then repartnered
with the RMI.
The addition of any further probe(s), or
replacements, into a multi-probe installation can
be achieved simply through the reconfiguration of
the probe to the same 'mode on' colour choice.
Acquisition mode
System set-up is achieved using Trigger Logic™
and powering on the RMI.
Partnering is only required during initial system
set-up. Further partnering is only required if either
the RLP40 or RMI is changed.
Partnering will not be lost by reconfiguration of
probe settings or when changing batteries, except
where multiple probe mode is selected.
Partnering can take place anywhere within the
operating envelope.

The stylus trigger force is the force exerted
on the component when the probe triggers.
However, the maximum force applied to
the component will occur after the trigger
point and will be greater than the trigger
force. The magnitude depends on a
number of factors affecting probe overtravel
including measuring speed and machine
deceleration. If the forces applied to the
component are critical, contact Renishaw
for further information.

Operating envelope
Radio transmission does not require line-of-sight
and will pass through small gaps and machine
tool windows. This allows easy installation, either
inside or outside the machine enclosure.
Coolant and swarf residue accumulating on the
RLP40 and RMI may have a detrimental effect
on transmission performance. Wipe clean as
often as is necessary to maintain unrestricted
transmission.
When operating, do not touch either the RMI
cover or the probe glass window with your hand,
as this will affect the 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 (122 °F to 140 °F).

RMI
NOTE: RLP40 / RMI installation with RLP40 in
radio-on configuration.
RLP40 has a built-in hibernate mode (battery
saving mode) that saves battery life when the RMI
is unpowered in radio-on (radio-off or time-off)
configurations. The RLP40 goes into hibernate
mode 30 seconds after the RMI is unpowered (or
the RLP40 is out of range). When in hibernate
mode, the RLP40 checks for a powered RMI
every 30 seconds. If found, the RLP40 goes from
hibernate mode to stand-by mode, ready for
radio-on.
Performance envelope
The RLP40 and RMI 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.

Stylus trigger force adjustment
Spring force within the probe causes the stylus to
sit in a unique position and return to this position
following each stylus deflection.
Stylus trigger force is set by Renishaw. The
user should only adjust trigger force in special
circumstances e.g. where there is excessive
machine vibration or insufficient force to support
the stylus weight.
To adjust the trigger force, turn the adjusting
screw anticlockwise (as shown) to reduce the
force (more sensitive); eventually it reaches a
stop. Turn the adjusting screw clockwise (as
shown) to increase the force (less sensitive). If
the internal screw becomes disengaged, remove
any pressure on the stylus and turn the key
anticlockwise to re-engage the thread.
Trigger forces in the XY plane vary around the
stylus and depend on trigger direction.
Stylus trigger force adjustment and use of
styli other than test stylus types may cause
probe repeatability to differ from the calibration
certificate results.

Calibrating the RLP40
Why calibrate a probe?
A spindle 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 the probe is
calibrated in the following circumstances:
• when a probe system is to be used for the
first time;
• when a new stylus is fitted to the probe;
• when it is suspected that the stylus has
become distorted or that the probe has been
crashed;
• at regular intervals to compensate for
mechanical changes of your machine tool;
• if repeatability of relocation of the probe
shank in the machine spindle is poor. In this
case, the probe may need to be recalibrated
each time it is selected.
It is good practice to set the tip of the stylus on-
centre, because this reduces the effect of any
variation in spindle and tool orientation (see page
3.6). A small amount of run-out is acceptable, and
can be compensated for as part of the normal
calibration process.
Three different operations are to be used when
calibrating a probe. They are:
• calibrating either in a bored hole or on a
turned diameter of known size;
• calibrating either in a ring gauge or on a
datum sphere;
• calibrating the probe length.
Calibrating in a bored hole or on a
turned diameter
Calibrating a probe, either in a bored hole or on
a turned diameter of known size, automatically
stores offset values between actual and
theoretical stylus ball position and also the
electronic ball radius of the stylus of the stylus
being used. The stored values are then used
automatically in the measuring cycles. Measured
values are compensated by these offsets so that
positional and size measurements relative to
spindle centre line are accurate.
Calibrating in a ring gauge or on a
datum sphere
Calibrating a probe either in a ring gauge or
on a datum sphere with a known diameter
automatically stores one or more value for the
radius of the stylus ball. The stored values are
then used automatically by the measuring cycles
to give the true size of the feature. The values are
also used to give true positions of single surface
features.
NOTE: The stored radius values are based on
the true electronic trigger points. These values are
different from the physical sizes.
Calibrating the probe length
Calibrating a probe on a known reference surface
automatically stores the position of the stylus ball
(probe length or geometry offset) relative to either
a turret or workpiece reference face.

RLP40 – RMI partnership
System set-up is achieved using Trigger Logic™
and powering the RMI. Partnering is only required
during initial system set-up. Further partnering
is only required if either the RLP40 or RMI is
changed, or a system is reconfigured for multiple
probes (multiple probe mode).
Partnering will not be lost by reconfiguring the
probe settings or when changing batteries, except
where multiple probe mode is selected. Partnering
can take place anywhere within the operating
envelope.
In configuration mode, configure the probe
settings as required until you reach the
"Acquisition mode" menu. Select "Acquisition
mode off".
Deflect the stylus to select 'Acquisition
mode on'.
Ensure this is done within 10 seconds
of the RMI signal LED flashing green.

Operating mode
NOTE: 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 reactivates 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 is
repeated.
