RMP40 basics
2.12.1
Introduction
RMP40 forms part of Renishaw's family of new
generation radio transmission probes. It is ideally
suited to large machine centres or where line-ofsight between probe and receiver is difficult to
achieve or where Z travel is limited.
RMP40 features an integrated probe module
delivering exceptional robustness and generous
overtravel.
RMP40 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 RMP40 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:
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
‘RMP40 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 RMP40 probe and the
machine controller.
• 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.
RMP40 installation guide

RMP40 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 RMP40 probe can be in one of three modes:
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.
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 RMP40 is ready for use.
Configuration mode: where Trigger Logic™ may
be used to configure the following probe settings.
When the filter is enabled, a constant 10 ms delay
is introduced to the probe output.
The RMP40 is factory set to trigger filter off.
NOTE:
approach speed to allow for the increased stylus
overtravel during the extended time delay.
It may be necessary to reduce the probe

RMP40 basics
RMP40 switch on method
Switch on options are configurable
RMP40 switch off method
Switch off options are configurable
Switch on time
Radio on
Radio switch on is commanded by
machine input.
Spin on
Spin at 500 rev/min for 1 second
minimum (6 seconds maximum).
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.
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.
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.
2 seconds maximum.
Note: The 2 seconds
starts from the
moment the spindle
reaches 500 rev/min.
Timer off (timeout)
Timeout will occur 12, 33 or 134
seconds (user configurable) after the
last probe trigger or reseat.
NOTE: After being switched on, the RMP40 must be on for 1 second minimum (the RMP40 must be
spun down before it can be spun off again) before being switched off.
RMP40 installation guide
2.4
RMP40 basics
Multiple probe mode
The RMP40 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.
RMP40 probes which are set to 'multiple probe
mode on' can coexist alongside any number of
RMP40 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™".
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 RMP40 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.
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 RMP40 probes are factory set to 'mode off'.
