SYSTEM DESCRIPTION
The MP18 Probe is used for job set up and workpiece measurement
on CNC machine tools. Signal transmission between transmitters and
recievers is non line of sight. The radio channel is selectable and signal
transmission range is up to distances of 3m (9.8ft).
FEATURES
SYSTEM OPERATION
●
Transmission of the probe trigger
signal using FM radio transmission
at 433MHz frequency.
The probe assembly is stored in the machine
tool changer as any other tool, and is transferred
to the machine spindle for probing routines.
●
User selection of the transmission
channel (up to 69 available),
permits many systems to operate
in close proximity, with no
interference between systems.
The probe head acts as an omni-directional switch
and is effective in the ± X, ±Y and +Z directions.
●
Switch on - switch off mode.
●
Two receivers to provide cover for
signal transmission dead spots.
●
M code switch on and off of the probe,
using an optional optical transmitter
module (OM16).
During operation, the probe stylus is driven
against a workpiece feature. On contact the radio
module probe (RMP3) transmits a probe signal to
the two radio modules machine (RMM2), using
frequency modulated (FM) radio waves.
The signal then passes via cable to the MI16
interface and onto the CNC machine control,
thereby recording the stylus contact position in
the machine tool registers. Two different contact
positions enable features to be measured.
Probing software is available from Renishaw

RMM2 with side
or rear cable exit
Radio Module Machine - transmits and receives signals
between machine control and Radio Module Probe (RMP3).
MI16
machine interface
Signals received by the RMM2, pass via coaxial cable to the MI16
machine interface, which decodes and converts them into solid state
relay (SSR) outputs for use by the machine tool’s CNC controller.
OM16 - optional
optical module
An M code causes the OM16 optical transmission module, to send
probe switch on/off signal to the RPM3.
PSU3 - optional
power supply unit
The MI16 draws 24V DC power from the CNC machine and presents
a load of up to 500mA. If this supply is not available from the machine
power can be supplied by a Renishaw PSU3 power supply unit.

RADIO MODULE MACHINE (RMM2)
Cable side exit and rear exit versions are available
phones or another radio probe operating on the
same channel.
An audio monitoring facility is provided to
diagnose causes of interference - see page 18.
RMM2 MOUNTING
Select a flat, metallic surface, ideally away from
corners and bulkheads.
The base of each RMM2 incorporates five
permanent magnets to allow temporary
attachment to a metal surface.
RMM2 RADIO ANTENNA
The RMM2 receives radio signals from the probe,
and passes the signals via a 10m (32ft) coaxial
cable to the MI16 interface.
Two RMM2 units are supplied with each system.
The system can operate with a single RMM,
but there may be areas where the radio signal is
weak. This is a characteristic of all radio systems.
The second RMM2 is positioned to provide good
reception over the probes full working area.
SIGNAL TRANSMISSION ENVELOPE
Radio signals can be transmitted and recieved up
to distance of 15 metres (49ft), in any direction.
Distances greater than this may be achievable
under certain circumstances.
Line of sight between the RMP3 and the RMM2
is not required and the signal can still be received
with the RMP3 fully enclosed in a bore.
Systems operating on the same channel should
be seperated by a distance of 100m (328ft), to
avoid interference with each other.
OPERATING ENVIRONMENT
It is important that the environment is free from
interference at the chosen transmission frequency.
Devices that may make operation difficult include
arc welders, pagers, remote control keys, mobile
Alternatively three clearance holes are provided
within the base for M4 fixing screws -10mm long
for permanent installation.
RMM2 POSITIONING
Each RMM2 must be installed with care in order
to receive as strong and reliable a signal as
possible from the probe/RMP3 transmission
module.
To guarantee reliability, the MI16 Interface has
two independent reception circuits, each support
one antenna (RMM2). Radio waves are a
coherent form of energy, and reflected signals
may add or subtract to the performance,
resulting in no signal in some positions. To avoid
this, a second RMM2 is recommended.
Commence by connecting a single RMM2 to the
MI16 interface. Position the RMM2 as close as
possible to the working envelope. Activate the
probe/RMP3.
The strength of the radio transmission signal is
observed using the MI16 interface front panel
Rx signal display - see page 18 item 6. Move the
probe around the working envelope and observe
the RX signal display. Identify positions in the
working envelope where the signal is weak or
disappears. A satisfactory signal is indicated by
the RX display signal bars remaining green.

INTERFACE GROUNDING
The MI16 is equipped with an internal power
transformer which ensures that the casing is
isolated from the external power source.
To maintain the isolation the positive (+) and
negative (-) wires must be connected without
contacting the chassis. Use of a shielded cable
is preferred.
The cable screen must be connected to ground
on the machine controller and to the primary
ground connection on the MI16 Interface connector
(item 1).
The MI16 is equipped with a chassis ground
tab (item 19) which should be used to connect the
MI16 enclosure to the nearest machine ground.
20
MI16 AUDIO DIAGNOSTICS
An audio facility, with adjustable volume, is
provided on the MI16 Interface to permit the
identification of interference sources.
With the RMP3 inactive no tone should be
audible; only background noise.
In either condition the sound should be
observed and any unusual sounds noted.
In the event of functional disturbances that
suggest radio interference, the audio facility
should be used:
Set the audio volume to maximum, using the
buttons on the front panel of the MI16.
The frequency of occurrence may then be
correlated to adjacent machinery
(arc welders, paging devices) to identify
the interference source.
When the RMP3 is active a continuous tone
should be audible, the tone changes when
the probe is triggered.
If the source of interference cannot be
eliminated, then a change in transmission
channel is recommended.

OPERATING ENVELOPE
The OM16 window and RMP2 LED’s should be wiped clean periodically to remove coolant residues.
Operation outside the temperatures specified for operational use (5°C to 50°C / 41°F to 158°F )
may result in some reduction in transmission range.
The maximum recommended distance between the OM16 and RMP3 is 3 metres.
OM16 FUNCTION
An M code from the CNC machine control
causes the OM16 to send an optical switch on
or switch off signal to the probe/RMP3.
The appropriate activation mode is selected
and programmed from the MI16 Interface.
The ring of LED’s around the probe body receive
OM16 optical signals in any probe orientation,
provided optical transmitter and receiver LED’s
are mutually in each other view.
OM16 MOUNTING
The module may be mounted directly to the
machine guarding, using the M32 locking nuts
provided on the OM16 body.
Alternatively a mounting bracket is supplied with
the OM16 module. The bracket securing screws
can be loosened to allow the OM16 LED’s to be
directed towards the probe LED’s.
Screws are then re-tightened.
The mounting bracket accepts an M10 size bolt
for attachment to guarding or bulkheads.
OM16 WINDOW
The chosen position for the OM16 should be
selected to avoid direct impact of machining
swarf on the OM16 window. Although the
window is 4mm thick toughened glass, long
term erosion will eventually reduce optical
signal strength.
OM16 LED
An orange LED is lit when a signal is sent.
To assist monitoring system status, the orange
LED must be visible to the operator during use.

The MI16 and the RMP3 programming
LED’s must be aligned and held within
100mm (3.93in) of each other for the
optical link to be established.
5.
Once the optical link has been established
the interface emits an audible beep every
½ second for 5 seconds and the front panel
displays the current RMP3 configuration.
10. Incorrect programming is indicated by
continuous audible beeps, flashing of
the channel number display and the
‘CONFIRM’ LED not lighting.
In this event the programming procedure
should be repeated.

Spring pressure within the probe causes the stylus
to sit in one unique position, and return to this position
following each stylus deflection.
Stylus pressure is set by Renishaw.
The user should only adjust spring pressure in special
circumstances e.g. excessive machine vibration or
insufficient pressure to support the stylus weight.
ENSURE THAT THE OMP IS KEPT
To adjust spring pressure, remove the probe head to
gain access to the spring pressure adjusting screw.
Slacken the locknut, and turn the adjusting screw
anticlockwise to reduce pressure (more sensitive)
or clockwise to increase pressure (less sensitive).
OTHER THAN CALIBRATION
A stop prevents damage, which could be caused
by overtightening the adjusting screw.
Finally tighten the locknut to 1Nm (0.74lbf.ft) and
replace the probe head.
CLEAN. DO NOT ALLOW COOLANT

DIAPHRAGM INSPECTION and REPLACEMENT
PROBE DIAPHRAGMS
The probe mechanism is protected from coolant
and debris by two diaphragms, these provide
adequate protection under normal working
conditions.
The user should periodically check the outer
diaphragm, for signs of damage and coolant
leakage. If this is evident replace the outer
diaphragm.
The outer diaphragm is resistant to coolant
and oils. However if the outer diaphragm is
damaged, the inner diaphragm could become
weakened with prolonged immersion in certain
coolants and oils.
The user must not remove the inner
diaphragm. If damaged, return the probe
to your supplier for repair.

ADDENDUM 1
Radio system component compatibility
Complete MP14 and MP16 probe systems may be exchanged with
complete MP18 and MP18-S probe systems.
Component compatibility
NOT ALL MP18 components are compatible with components used
with the earlier MP14 radio transmission system.
Components with identical model name/number are interchangeable
between systems.
Earlier MP14 systems incorporating an RMP, RMM and the MI14 interface
DO NOT function with current systems using the RMP2
(used with MP16), RMP3 (used with MP18), RMM2, MI16 interface
and the OM16 optical module.
Probe/RMP2/RMP3
The RMP2 and RMP3 will communicate with the RMM and RMM2,
provided they are set to operate on the same channel.
The MP18 probe is smaller and lighter than the MP14 and MP16 probes.
RMM and RMM2 antenna
Both antenna use the same base. The RMM2 antenna is shorter than
the RMM antenna.
Interface unit
The MI14 interface has been replaced by the MI16 interface, both
units are the same size. All electrical outputs and inputs to the MI16 Interface
remain unchanged from the MI14 Interface.
(Note that a 16 pin plug is required for connection to the MI16 Interface rather
than the 14 pin connector used on the MI14 Interface. The two extra contacts
allow connection to the OM16 Optical Module).

ADDENDUM 3
SELECTION OF MI16 SENSITIVITY
The MI16 MK3 version has an integral switch which allows the selection of the radio
reception sensitivity level.
The switch is located on the rear panel.
Switch : 3 positions
The sensitivity can be selected from three levels:
HIGH :
The reception sensitivity is strong.
ð The reception distance is longer.
ð The parasitic sensitivity is increased.
LOW :
The reception sensitivity is lower.
ð The reception distance is smaller.
ð The parasitic sensitivity is diminished.
MEDIUM : This position is a compromise between the two previous.
ADVICE ON SELECTION OF SWITCH POSITION
The choice of the switch position is dependent on the probe power version sold in the
different markets.
The following positions are recommended:
HIGH = USA Market
LOW = CEE Market
MEDIUM = JAPAN Market
Note : The choice of the MI16 interface sensitivity does not replace the procedures for
the antenna installation (see RMM2 ANTENNA-Operating envelope and installation).
