applicable technical knowledge and a trained risk assessor) with consideration for
the safety of all personnel. The risks identified must be mitigated prior to using the
product. The risk assessment should pay particular attention to machine, manual
handling, mechanical, laser, electrical, power and fibre optic safety.
Based on current research, the wireless devices used in this product would not
seem to pose a significant health problem for the vast majority of pacemaker
wearers. However, people with pacemakers may want to ensure a minimum
distance of 3 cm between the product and pacemaker.
Safety warnings
The XR20-W rotary axis calibrator system is designed to be used to test machine
tools. As such, the user will need to prepare and run a part program which moves
the machine as required. Do not spin the optics. It is assumed therefore that the
user is thoroughly familiar with the operation of the machine tool and its controller
and knows the location of all emergency stop switches. Also, if it is necessary to
operate the machine with the guards or any safety feature removed or disabled, it
is the responsibility of the operator to ensure that alternative safety measures are
taken in line with the machine manufacturer’s operating instructions or relevant
codes of practice. Safety procedures should be in accordance with the user’s risk
assessment.
The XR20-W device works in conjunction with a Renishaw laser system. Before
using the laser system, please read the safety section of the relevant Laser user
guide.
The XR20-W can reflect the laser beam from the laser around the room as it
rotates. Consideration should be given to other users working in the area.
If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

Mechanical safety
• When setting up and mounting Renishaw laser calibration equipment,
beware of pinch and/or crush hazards that may be created e.g. due to
magnetic mounting bases.
• Beware of trip hazards that may be created when using Renishaw
equipment, e.g. due to trailing cables.
• Exercise caution if components are to be mounted to moving or rotating
machinery. Beware of cables becoming entangled.
• Exercise extreme caution if Renishaw equipment is to be mounted to
machinery that may accelerate rapidly or move at high speed, which could
lead to items colliding or being ejected.
• If it is necessary to operate the machine with the guards or any safety
feature removed or disabled, it is the responsibility of the operator to
ensure that alternative safety measures are taken in line with the machine
manufacturer’s operating instructions or relevant codes of practice.
• If you are using a part program or error correction parameters generated by
Renishaw software, it is the responsibility of the user to validate these at low
feedrate and be prepared to operate the emergency stop button if necessary.
Laser optical safety
• In accordance with (IEC) EN60825-1, Renishaw XL-80 and XM systems
used to provide a laser source for XR20-W are class 2M lasers and safety
goggles are not required (under normal circumstances the eye will blink and
look away before damage can occur).
• Do not stare directly into the laser beams or view them with optical
equipment such as telescopes, convergent mirrors or binoculars as
permanent retinal damage could occur.
• Do not direct the beam at other people or into areas where people
unconnected with the laser might be present. It is safe to view a diffusereflected beam during system alignment.

Transportation
Please ensure that you comply with international and national battery transport
regulations when transporting batteries or XM system kits.
The XR20-W uses a lithium ion battery. Lithium batteries are classified as
dangerous goods and strict controls apply on their shipment by air. To reduce the
risk of shipment delays, should you need to return your XR20-W to Renishaw for
any reason, do not return any batteries.
The operation of wireless appliances on aircraft is forbidden by many airlines
to prevent interference with communication systems. Remove the battery from
the receiver unit when boarding an aircraft to ensure it cannot be switched on
inadvertently.

XR20-W rotary axis calibrator
System overview
XR20-W is a rotary axis calibrator designed for measuring rotary axes, key
features include:
• Compatible with Renishaw’s XL-80 or XM systems
• Compact and lightweight
• Quick and simple mounting system
• Easy alignment with built-in alignment aid
• Wireless operation by utilising Bluetooth communication
• Battery powered (can be powered by external USB if required)
• Typical system configurations are shown in figure 1 and 2 for use with XL-80
and XM-60.
Figure 1 - typical set-up for calibrating a rotary axis using XL-80 as the laser
reference.
Figure 2 - typical set-up for calibrating a rotary axis using XM as the laser
reference.
The CARTO data capture software uses both the measured angle and the
position from the XR20-W’s internal encoder scale to very accurately measure
the positioning performance of the table under test. The rotation of an axis is
calibrated by rotating it sequentially through a number of angular targets, pausing
at each defined target to capture a reading. As the axis rotates, the software
counter-rotates the XR20-W to ensure that the laser beam is returned back to the
laser, maintaining signal strength.
