Safety
Information to the user
This product is supplied with non-rechargeable batteries that do not contain lithium. For specific
battery operating, safety and disposal guidelines refer to the battery manufacturers’ literature.
• Do not attempt to recharge the batteries.
• Replace the batteries only with the specified type.
• Do not mix new and used batteries in the product.
• Do not mix different types or brands of batteries in the product.
• Ensure that all batteries are inserted with the correct polarity in accordance with the instructions
in this manual and indicated on the product.
• Do not store the batteries in direct sunlight.
• Do not expose the batteries to water.
• Do not expose the batteries to heat or dispose of the batteries in a fire.
• Avoid forced discharge of the batteries.
• Do not short circuit the batteries.
• Do not disassemble, apply excessive pressure, pierce, deform or subject the batteries to impact.
• Do not swallow the batteries.
• Keep the batteries out of the reach of children.
• If the batteries are swollen or damaged do not use them in the product and exercise caution
when handling them.
• Dispose of waste batteries in accordance with your local environmental and safety laws.
Ensure that you comply with international and national battery transport regulations when transporting
the batteries or this product with the batteries inserted. Lithium metal batteries are classified as
dangerous goods for transportation and require labelling and packaging in accordance with the
dangerous goods regulations before being offered for transportation. To reduce the risk of shipment
delays, should you need to return this product to Renishaw for any reason, do not return any batteries.
In all applications involving the use of machine tools, eye protection is recommended.
The OMP60 has a glass window. Handle with care if broken to avoid injury.

Information to the machine supplier/installer
It is the machine supplier’s responsibility to ensure that the user is made aware of any hazards
involved in operation, including those mentioned in Renishaw product literature, and to ensure that
adequate guards and safety interlocks are provided.
If the probe system fails, the probe signal may falsely indicate a probe seated condition. Do not rely on
probe signals to halt the movement of the machine.
Information to the equipment installer
All Renishaw equipment is designed to comply with the relevant UK, EU and FCC regulatory
requirements. It is the responsibility of the equipment installer to ensure that the following guidelines
are adhered to, in order for the product to function in accordance with these regulations:
• any interface MUST be installed in a position away from any potential sources of electrical noise,
(for example power transformers, servo drives);
• all 0V/ground connections should be connected to the machine “star point” (the “star point” is a
single point return for all equipment ground and screen cables). This is very important and failure
to adhere to this can cause a potential difference between grounds;
• all screens must be connected as outlined in the user instructions;
• cables must not be routed alongside high current sources (for example, motor power supply
cables), or be near high-speed data lines;
• cable lengths should always be kept to a minimum.
Equipment operation
If this equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
Optical safety
This product contains LEDs that emit both visible and invisible light.
OMP60 is ranked Risk Group: Exempt (safe by design).
The product was evaluated and classified using the following standard:
BS EN 62471:2008 The photobiological safety of lamps and lamp systems.
Renishaw recommends that you do not stare at or look directly into any LED device, irrespective of its
risk classification.

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™.
