This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device may accept any interference
received, including interference that may cause
undesired operation.

FCC Section 15.105

This equipment has been tested and found to
comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC rules. These limits
are designed to provide reasonable protection
against harmful interference when the equipment
is operated in a commercial environment.

This equipment generates, uses , and can radiate
radio frequency energy and, if not installed and
used in accordance with the instruction manual, may
cause harmful interference to radio communications.

Operation of this equipment in a residential area is
likely to cause harmful interference, in which case
you will be required to correct the interference at
your own expense.

FCC Section 15.21

The user is cautioned that any changes or
modifications not expressly approved by Renishaw
plc, or authorised representative could void the
user’s authority to operate the equipment.

SAFETY

Information for the user

Beware of unexpected movement. The user
should remain outside of the full working
envelope of probe head/extension/probe
combinations.

Handle and dispose of batteries in according to
the manufacturers recommendations. Use only
the recommended batteries. Do not allow the
battery terminals to contact other metallic
objects.

In all applications involving the use of machine
tools or CMMs, eye protection is recommended.

Refer to the machine supplier’s operating
instructions.

Information for the machine supplier

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 documentation,
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 stop the
machine’s movement.

System performance

System performance

RMP60 and RMP60M have identical user options and radio performance

Operating envelope

Radio transmission does not require line-of sight
and will pass through very small gaps and
machine tool windows. This allows easy
installation, either inside or outside the machine
enclosure.

Coolant and swarf residue accumulating on the
RMP60/M and RMI may have a detrimental
effect on transmission performance. Wipe clean
as often as is necessary to maintain unrestricted
transmission.

When operating, do not touch either the RMI
cover or the probe glass window with your hand,
as this will affect the performance.

Operation in extremes of temperature will result
in some reduction in range.

RMI position

The probe system should be positioned so that
the optimum range can be achieved over the full
travel of the machine axes. Always face the front

cover of the RMI in the general direction of the
machining area and the tool magazine, ensuring
both are within the operating envelope.

To assist in finding the optimum position of the
RMI, the signal quality is displayed on an RMI
signal LED.

Note: RMP60/M in radio-on configuration

The RMP60/M has a built-in hibernate mode
(battery saving mode) that saves battery life
when the RMI is unpowered in radio-on
(radio-off or time-off) configurations.

The RMP60/M goes into hibernate 30 seconds
after the RMI is unpowered (or the RMP60 is
out of range).

When in hibernate, the RMP60/M checks for a
powered RMI every 30 seconds. If found, the
RMP60/M goes from hibernate to standby,
ready for radio-on.

Repeatability of 1.0 µm (40 µ in) is valid for a

test velocity of 480 mm/min (1.57 ft/min) at the
stylus tip, using a stylus 50 mm (1.97 in) long.

RMP60 probe + RMI

RMP60 and RMI must be within each other’s

shows line-of-sight performance, however radio
transmission does not require line-of-sight as

the 15 m (49.2 ft) system operating range

Stylus with weak link

Stylus weak link

Must be used with steel styli.

For optimum metrology performance, do not use
the weak link with ceramic or carbon fibre styli.

Fitting stylus with weak link onto RMP60

In the event of excessive stylus overtravel,
the weak link is designed to break, thereby
protecting the probe from damage.

Take care to avoid stressing the weak link
during assembly.

Probe settings

Probe settings

The RMP60 probe can be in one of three modes:
Stand-by mode - The RMP60 is waiting for a

switch on signal.
Operating mode - Activated by one of the

switch on methods described on this page.
In this mode the RMP60 is now ready for use.

Configuration mode - The trigger logic
configuration method allows the following
settings to be configured.

Switch-on / switch-off methods

The following switch on / switch off options
can be configured:

1. Radio on / Radio off

2. Radio on / Timer off

3. Spin on / Spin off
