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.
