A workpiece set-up and inspection probe is in effect another
tool in the system. A probe cycle may be included at any
stage of the machining process.
Signals are transmitted between the probe and the machine
control, via the OMP and OMM + MI 12 or alternatively the
OMP and OMI.

OMM TANDEM MOUNTING
Installations with exceptionally long
spindle travel, may require a
second OMM to cover signal
reception over the full working
envelope of the probe.
The reception cones of OMM 1
and OMM 2 overlap, so they
act as one receiver.
REMOTE INDICATOR
When the probe contacts a surface
an MI 12 LED changes state and a
bleep is emitted.
If the MI 12 is hidden from the
operator, a remote lamp or bleeper
may be placed in a position where
it is easily seen or heard.
OMM TWIN MOUNTING
Each spindle of a twin
spindle machine can
accept a probe.
Although both OMM 1
and OMM 2 are
switched on, only one
probe may be used at
any one time.

OPERATING ENVELOPE
Natural reflective surfaces within the machine may
increase the signal transmission range.
Coolant residue accumulating on the OMP diodes
and OMM or OMI window, will have a detrimental
effect on transmission performance. Wipe clean
as often as is necessary to maintain unrestricted
transmission.
Operation in temperatures of 0 °C to 5 °C or 50 °C to
60 °C (32 °F to 41 °F or 122 °F to 140 °F) will result in
some reduction in range.
WARNING
If two systems are operating in close proximity
take care to ensure that signals transmitted from
the OMP on one machine, are not received by the
OMM or OMI on the other machine, and vice
versa.
OMM and OMI POSITION
To assist finding the optimum position of the OMM
during system installation, signal strength outputs
are available on the MI 12 interface.
OMI signal strength is displayed on an OMI
multicoloured LED.

Switch-off options are selected by operating an
internal probe switch - see opposite.
1. Optical-on and timer-off (time out) factory set.
A timer switch automatically returns the probe
to the stand-by mode after 33 or 134 seconds.
The timer is factory set to 134 seconds.
The 33 second option is selected by resetting
the internal probe switch. The timer is reset for
afurther 33 or 134 seconds on, each time the
probe triggers during the operating mode.
Note : A start signal received during the time
the probe is on, also resets the timer for a further
33 or 134 seconds on.
2. Optical-on and optical-off ( optional)
Optical switch-off is commanded by a software
M code. Debounce times apply.
Modes of operation
The MP10 has two modes of operation.
1. Stand-by mode - The OMP uses a small
current, while passively waiting for the
switch on signal.
2. Operating mode - Activated by one of the
methods described below. Probe signals
are only transmitted during the operating
mode.
MP10 power on/off
MP10 power switch on/off, only occurs when the
MP10 is located within the switch on/off envelope
of the OMP and OMM/OMI.
Debounce time
After the probe is switched on there is a time
delay before it can be switched off. This delay is
factory set to 5 sec or it can be reset to 9 sec by
switching the internal probe switch. A similar
delay occurs after switch off, before it can be
switched on again.
SWITCH-ON SWITCH-OFF
Switch-on options are selected by MI 12 or OMI
switch settings - see MI 12 or OMI handbook.
1. Manual start (optical-on) - MI 12 start button.
2. Machine start (optical-on) - optical switch-on
via software M code command - factory set.
3. Auto start (optical-on) causes the system to
send an optical start signal once every second
and does not require a machine control input.
Note : Auto start should not be selected when the
MP10 is set to the optical-on / optical-off option.
(An auto start signal will force the MP10 to switch on
then off at 5 or 9 second intervals).
Following switch-on, debounce time must elapse,
before the probe is switched off.
MODES OF OPERATION

Only qualified persons
should change settings
Remove the probe head to gain
access to the switches and sockets.
OPTIONS SETTING SWITCH
System settings are shown
opposite.
ENHANCED TRIGGER CIRCUIT
Probes subjected to high levels of
vibration or shock loads, may
release spurious readings. The
enhanced trigger circuit improves
the probes resistance to these
effects.
When the circuit is enabled, a
constant nominal 7 millisecond
delay is introduced to the probe
output.
It may be necessary to revise
program software to allow for the
increased stylus overtravel.
To activate the enhanced trigger
circuit, the wire link is transferred
manually :
From SKT 1-2 (factory set)
To SKT 3-2 (enabled)

BATTERY LIFE EXPECTANCY
Alkaline battery
Duracell type MN 1604 or equivalent
Typical battery reserve life.
Using an alkaline battery at 5% usage,
the probe will typically continue to
operate for 8 hours, after the
MI 12/OMI low battery LED lights up.
Dead battery indication
When the battery voltage drops below
the threshold where performance can
be guaranteed, the MP10 probe status
LED will change to constant red.
The probe output relay will also be
forced into its open state, causing the
machine to stop, until a new battery is
inserted.
The probe will revert to the stand-by
mode after changing the battery.
1-14
Probe battery
Power for the probe is supplied by a type PP3
9V battery.
The Probe status LED indicates when the
battery has come to the end of its useful life.
Low battery indication
When MI 12 or OMI low battery LED lights up,
battery voltage is low and the end of useable
battery life is approaching.
(The low battery LED will only light up during
the probe operating mode)
- see APPENDIX pages 1-39 and 1-40.
The machine control may also be programmed
to flag up a low battery alarm.

Stylus
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.
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).
A stop prevents damage, which
could be caused by overtightening
the adjusting screw.
Finally tighten the locknut to 1 Nm
(0.74 lbf.ft) and replace the probe
head.
ENSURE THAT THE OMP IS KEPT
CLEAN.

Two probe/shank mounting configurations are
used to obtain the stylus on-centre setting.
1. Adjusting plate
Translational adjustment allows the probe to
slide across the shank end face.
2. Combination of adjusting plate and centre
ball
Translational adjustment + centre ball pivot,
for applications where the stylus stem must
be parallel to the side of a bored hole, to avoid
stem contact.
Stylus on-centre adjustment
Stylus alignment with the spindle centre line need
only be approximate, except in the following
circumstances.
1-16 SHANK MOUNTING AND STYLUS ON-CENTRE ADJUSTMENT
1. When probe vector software is used.
2. When the machine control software
cannot compensate for an offset stylus.
How to check stylus position
Stylus tip and stem position are established
using a low force (less than 0.2 Nm/ 0.045 lbf)
dial test indicator or setting gauge.
Alternatively rotate the stylus ball against a flat
surface. Alignment is good when the stylus ball
maintains a consistent distance from the flat
surface.
