2.1
Introduction
The OMP60 is an optical machine tool probe suitable for use on medium to large machining and multi-
tasking centres. It is designed to resist optical interference, false triggering and shock.
The OMP60 can be operated in either ‘Legacy’ or ‘Modulated’ optical transmission modes – see probe
settings for further details.
When operating in ‘Legacy’ mode, the OMP60 is compatible with an OMM receiver and an MI 12
interface, or with an OMI receiver/interface.
When operating in ‘Modulated’ mode, the OMP60 becomes compatible for use with an OMM-2 or
OMM-2C receiver with an OSI or OSI-D interface, or with an OMI-2 / OMI-2T / OMI-2H / OMI-2C
receiver / interface, to provide substantially increased resistance to light interference.
In ‘Modulated’ mode, it is possible to define the probe ID. This is factory set to PROBE 1, but can be
changed to PROBE 2 for use with twin probes or PROBE 3 for use with multiple probe systems.
All OMP60 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:
•Switch-on / switch-off method
•Enhanced trigger filter setting
•Optical transmission method
•Optical power
Getting started
Three multicolour probe LEDs provide visual indication of selected probe settings.
For example:
•Switch-on and switch-off methods
•Probe status – triggered or seated
•Battery condition

OMP60 basics
System interface
The interface conveys and processes signals between the probe and CNC machine controller.
OMM-2 or OMM-2C receiver with OSI or OSI-D interface or OMI-2 / OMI-2T / OMI-2H / OMI-2C
receiver / interface (modulated transmission)
The OMI-2T receiver / interface or OMM-2 receiver with OSI or OSI-D interfaces are the recommended
interfaces for use with the OMP60 as they provide substantially increased resistance to light
interference whilst providing the user greater flexibility to operate a multiple probe system.
OMI or OMM with MI 12 (legacy transmission)
Alternative interfaces are the OMI or OMM with the MI 12 interface unit.
MI 7 interface unit
CAUTION: Systems using the earlier MI 7 interface in place of the MI 12 interface are not compatible
with OMP60.
Trigger Logic™
Trigger Logic (for more information, see page 4.1, “Reviewing the probe settings”) 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 uses a sequence of stylus
deflections (triggering) to systematically lead the user through the available choices to allow selection
of the required mode options.
A Probe setup app is available that simplifies this process with clear, interactive instructions and
informative videos and is available for download on the App Store and Google Play.
or
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 (for more information, see
page 4.1, “Reviewing the probe settings”).
Probe modes
The OMP60 probe can be in one of three modes:
Standby mode – Probe is waiting for a switch-on signal.
Operational mode – When activated by one of the switch-on methods, the probe is switched on and
ready for use.
Configuration mode – Ready to change the probe settings using Trigger Logic™.

2.4
OMP60 basics
Enhanced trigger filter
Probes subjected to high levels of vibration or shock loads may output probe trigger signals without
having contacted any surface. The enhanced trigger filter improves the probe’s resistance to these
effects.
When the filter is enabled, a constant nominal 10, 20 or 40ms delay is introduced to the probe output.
It may be necessary to reduce the probe approach speed to allow for the increased stylus overtravel
during the extended time delay.
Factory set to OFF.
Optical transmission method
Probes subjected to particular forms of light interference may accept spurious start signals.
The OMP60 can be operated in either ‘Legacy’ or ‘Modulated’ optical transmission mode.
Legacy mode
A start filter improves the probe’s resistance to these effects.
When Legacy (start filter on) is enabled, an additional one second delay is introduced to the probe
activation (switch on) time.
It may be necessary to revise the probe program software to allow for the increased activation time.
Modulated mode
The OMP60 becomes compatible for use with the OMM-2 or OMM-2C receiver with OSI or OSI-D
interface or with an OMI-2 / OMI-2T / OMI-2H / OMI-2C receiver / interface to provide substantially
increased resistance to light interference.
Modulated transmission in the OMP60, is capable of providing three different coded start signals.
This allows the use of two probes with an OMI-2T receiver / interface and up to three probes with an
OMM-2 receiver with a OSI or OSI-D interface respectively.
Twin/multiple probe system
To operate in a twin or multiple probe system, one probe must be set to PROBE 1 start and the other
probe must be set to PROBE2 start (OMI-2T or OMM-2 with OSI or OSI-D) or PROBE3 start (OMM-2
with OSI or OSI-D only). These settings are user configurable.
In a twin probe system, such as a spindle probe and an optical tool setting probe, the spindle probe
needs to be set to PROBE 1 start and the tool setter to PROBE 2 start.
In a multiple probe system, with two spindle probes and one optical tool setting probe, the two spindle
probes needs to be set to PROBE 1 and PROBE 2 start, respectively, and the tool setter would be set
to PROBE 3 start.

Optical power
Where the separation between the OMP60 and the OMI-2 / OMI-2T / OMI-2H / OMI-2C / OMM with
MI 12 or OMM-2 with OSI or OSI-D is small, low optical power may be used. In this setting, the optical
transmission range will be reduced as shown on the performance envelopes so that battery life will be
extended.
Dotted lines on the performance envelopes represent the OMP60 in low optical power.
Low optical power should be used whenever possible for increased battery life.
Maximum battery life is achieved when Lithium Thionyl Chloride (LTC) batteries are used in
conjunction with low power mode.
The probe is factory set to standard optical power.

Installing the OMP60
System installation
Operating envelope
The OMP60 / OMI or OMM with MI 12 system uses legacy transmission. When used with the OMM-2
receiver with OSI or OSI-D interface or the OMI-2 / OMI-2T / OMI-2H interface / receiver, the OMP60
uses modulated transmission.
Natural reflective surfaces within the machine may increase the signal transmission range.
Coolant and swarf residue accumulating on the probe or receiver / interface windows will have a
detrimental effect on transmission performance. Wipe clean as often as necessary to maintain
unrestricted transmission.
CAUTION: If two or more systems are operating in close proximity to each other, take care to ensure
that signals transmitted from the OMP60 on one machine are not received by the receiver on the other
machine, and vice versa. When this is the case it is recommended that the OMP60 low optical power is
used and that the low range setting is used on the receiver.

Installing the OMP60 with an OMM-2C receiver with OSI or OSI-D
interface
Operating envelopes
When used with an OMM-2C receiver with OSI or OSI-D interface, the OMP60 uses modulated
transmission.
Natural reective surfaces within the machine may increase the signal transmission range.
For best system performance, ensure that the OMM-2C receiver with OSI or OSI-D interface is
mounted in a position which is not directly in front of a light source.
Coolant and swarf residue accumulating on the probe, interface or receiver windows will have a
detrimental effect on transmission performance. Wipe clean as often as is necessary to maintain
unrestricted transmission.
WARNING: Ensure the machine tool is in a safe condition and power is removed before removing
covers. Only qualied persons should adjust switches.
CAUTION: If two systems are operating in close proximity to each other, take care to ensure that the
signals transmitted from the OMP60 on one machine are not received by the receiver on the other
machine, and vice versa. When this is the case, it is recommended that the OMP60 low optical power
is used.

Performance envelope of OMM-2C with OMP60
Reflective surfaces within the machine cabinet may increase the signal transmission range.
Coolant residue accumulating on the windows of the OMM-2C and OMP60 will have a detrimental
effect on transmission performance. Wipe the windows clean as often as necessary to maintain
unrestricted transmission.
For best system performance, ensure the OMM-2C is mounted in a position which is not directly in
front of a light source.
The probe and OMM-2C may deviate from the optical centre line, provided opposing light cones
always overlap, with transmitters and receivers in the other’s field of view (eye-to-eye).
In multiple probe mode applications, OMP60 may be configured as Probe 1, Probe 2 or Probe 3.
CAUTION: If two systems are operating in close proximity, take care to ensure that the signals
transmitted from the OMP60 on one machine are not received by the OMM-2C on another machine
and vice versa.
