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.
Under certain circumstances, 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.

• A choice of manual (jog) mode or automated mode.
• A solution that is compatible with a range of Renishaw probes as well as the Primo system.
GoProbe training kit
To ensure the maximum benet from the Primo system, Renishaw provides each Primo customer with a
GoProbe training kit: the training kit helps new users to get up and running with their new probing system
quickly and easily.
The training kit centres on the GoProbe training part, which has been designed to incorporate the most
common features encountered during automated setting and manufacturing. The GoProbe training part is
used to demonstrate all the probing cycles and is used in the e-learning practical exercises.
The GoProbe e-learning course is a PC-based course that will guide both new and experienced users
through the basics of probing using a combination of intuitive tutorials, interactive quizzes and practical
exercises.
By completing this training the user will be able to check that the Primo system is ready for use, and will be
able to use part setting, tool setting and probe set‑up cycles with condence.
Other learning aids included in the training kit are the pocket guide and quick-reference tool, for
convenient continual use at the machine. A GoProbe smartphone app is also available – see
www.renishaw.com/goprobe for details.
Each Primo system should be supplied with a training kit from your machine tool supplier. If you have not

Primo™ radio part setter and Primo™
radio 3D tool setter basics
Introduction
When used within a Primo system:
• The Primo™ radio part setter enables part set-up and inspection on machining centres.
• The Primo™ radio tool setter enables tool setting and broken tool detection (length and diameter).
The part setter and tool setter deliver interference-tolerant radio transmission through the use of
frequency-hopping spread spectrum (FHSS), allowing multiple systems to work in the same machine shop
without interference. Using radio transmission enables operation without line-of-sight.
Getting started
The part setter and tool setter are tted with LEDs to provide visual indication of their status as well as
overall system status. For further information, see "Part setter and tool setter LED guide" on page 5-18,
and "Interface LED signals" on page 5-20.
Credit
The Primo system requires credit to function. Credit comes in the form of a credit token. This is inserted
into the part setter. For further information, see "Installing the credit token cassette" on page 5-29 and
"Changing the credit token" on page 5-30. The credit is then transferred to the interface. For further
information, see "Credit transfer" on page 5-32.
Modes of operation
Standby mode: the interface is waiting for a switch-on signal from the machine tool before it can send a
switch-on signal to the equipment.
Operational mode: this is activated by a switch-on signal from the interface or by spinning the spindle
(part setter only). The equipment is ready for use.
Acquisition mode: this is used to partner the part setter and tool setter with the interface. For further
information, see "Acquisition method" on page 5-25.
Credit transfer mode (part setter only): this is used to transfer credit from the credit token via the part
setter to the interface. For further information, see "Credit transfer" on page 5-32.

2-2 Primo™ system: Radio part setter and radio 3D tool setter basics
Congurable settings
These settings can be congured by changing the DIP switches on the interface. For further information,
see "Switch SW1 output conguration" and "Switch SW2 output conguration" on page 3-5.
Function Description Factory setting
Part setter
switch-on/
switch-off method
Radio on/radio off Commanded by machine output.
Turn‑on time is 1second maximum.
Radio on/radiooff
Spin on/spin off Spin at 1000 r/min for 1.5 seconds
minimum.
Enhanced trigger lter The enhanced trigger lter improves the
equipment's resistance to false triggers
caused by rapid traversing or excessive
vibration.
OFF
Hibernation mode When the part setter or tool setter is
in standby mode and the interface
is powered off or out of range, the
equipment enters hibernation (low
power) mode after a timeout. The
part setter or tool setter ‘wakes’ from
hibernation periodically to check for
their partnered interface. The ‘wake’
signal is sent every 30 seconds when
hibernation is enabled.
ENABLED
Tool setter switch-on/switch-off
The switch‑on/switch‑off method for the tool setter is not user‑congurable. The method used is radio on/
radio off.
Enhanced trigger lter
When the lter is enabled, an additional 10 ms lter delay is introduced to the equipment output.
It may be necessary to reduce the part setter’s approach speed to allow for the increased stylus overtravel
during the extended time delay.
Recalibration
If settings are changed via the interface DIP switches, it is vital that the equipment is recalibrated (see
"Calibrating the Primo equipment" on page 5-16, for further information).

2-3
www.renishaw.com/primo
Acquisition mode
The partnering of the part setter or tool setter with the interface is described on page 5-25, “Acquisition
method”.
NOTE: To place the interface in acquisition mode, turn the interface off, then on again.
Partnering is required during initial Primo system set-up or if the part setter switch-on method is changed.
Partnering will not be lost by reconguration of the equipment settings or when changing the batteries.
Partnering can take place anywhere within the performance envelope. For more information, see
"Performance envelopes" on page 5-2.
Primo credit token
NOTE: The Primo system will not work without credit being available in the system.
The standard credit token contains 6months’ worth of credit. For more information, see "Installing the
credit token cassette" on page 5-29.
Primo upgrade credit token
An upgrade credit token enables the Primo system to work for an unlimited period.
Credit transfer
Credit is loaded into the Primo system by transferring credit from the credit token into the interface. For
more information, see "Credit transfer" on page 5-32.
How to purchase a credit token
You can purchase 6-month credit tokens and upgrade credit tokens from the Primo website:
wwwrenishaw.com/primo.
You can also contact your local Renishaw supplier (see www.renishaw.com/contact).

2-4 Primo™ system: Radio part setter and radio 3D tool setter basics
Low credit indicators
When any of these low credit indicators are shown, it is recommended that a new credit token is loaded
into the system.
1. Equipment LEDs ash yellow.
Slow ash Maximum 21 days’ credit remaining
Fast ash Maximum 10 days’ credit remaining
2. Interface low credit/low battery LED is illuminated (indicates low credit [maximum 21 days] or low
battery).
3.
Constant
Interface digital display (indicates the number of days of credit remaining). When the remaining credit
display reads 0 days, the Primo system will stop working and new credit must be loaded into the
system to continue operation.
4. Low credit/low battery solid-state relay (SSR) output from the interface, which can be connected to the
machine controller. When credit is running low, the SSR changes state. The SSR can be congured
normally open or normally closed. For further information, see "Switch SW1 output conguration" and
"Switch SW2 output conguration" on page 3-5.

www.renishaw.com/primo
Part setter operation
The part setter operates as a highly accurate and repeatable mechanical switch that triggers as the stylus
deects against a surface.
• The part setter can trigger in the X, Y and Z axes.
• The part setter can be used for work co-ordinate setting and for workpiece measurement.
• A trigger signal is sent directly to the CNC controller so that offsets can be updated – no manual
intervention is required.
Tool setter operation
The tool setter enables accurate machining by measuring the length and diameter of tools using the same
highly accurate and repeatable switch mechanism as the part setter.
• The tool is set in the Z axis for tool length measurement and broken tool detection.
• Rotating tools are set in the X and Y axes for tool radius measurement.
Rotate the tool in the
reverse direction for
diameter setting.

www.renishaw.com/primo
Primo™ interface basics
Introduction
The interface enables communication between the machine tool, part setter and tool setter using radio
frequency transmission.
Power supply
The Primo interface can draw its supply from the CNC machine tool’s 12 Vdc to 30 Vdc supply and present
a peak load of up to 500 mA during turn on (typically < 100 mA from 12 V to 30 V).
WARNING: The Primo system has been designed to work over the specied supply voltage range and
should be powered with a suitable protected extra low voltage supply (PELV). Renishaw cannot guarantee
user safety if the Primo system is operated outside of these requirements.
NOTE: If the Primo system is using an upgrade credit token and the interface is returned to Renishaw, the
upgrade credit token must be returned with the interface for identication purposes.

conguration" on page 3-5. For the full interface wiring diagram, see "Interface wiring diagram" on page 5-13.
Interface outputs
There are four SSR outputs:
• Probe status 1
• Probe status 2
• Error
• Low credit/low battery
All outputs can be inverted by using the interface DIP switches SW1 and SW2. For further information, see
"Switch SW1 output conguration" and "Switch SW2 output conguration" on page 3-5).
NOTE: The term ‘Probe status’ refers to the measurement hardware in the system interacting with the
interface and can therefore refer to the part setter or the tool setter.
