2. Safety precautions
Make sure to read the following safety precautions for the correct use and operation of the UXM.
2.1 General precautions
The UXM uses laser radiation for detecting objects within configured area.
Perform pre-operation tests in order to verify the performance of the UXM.
User should prepare test pieces for detection capability verification test. The test piece should emulate
the smallest object that is intended to be detected during operation.
Operate the UXM within the specifications described in this user’s manual. Also, perform the necessary
maintenance to prevent deterioration of UXM’s detection capability. (Refer to chapter 9)
Do not modify or disassemble the UXM. This could compromise the IP67 housing rating. Such
modifications will void the warranty.
The UXM is not a safety device. Do not use this sensor for the purpose of protecting humans.
The detection capability of the UXM will decrease if dust covers the optical window. Regular cleaning
of the optical window is necessary while working under dusty environment.(Refer to section 9.5)
The UXM should be disposed as industrial waste or in accordance with the local disposal directives.
2.2 Operating environment
Make sure that the UXM’s operating environment is within the stated specification (temperature,
humidity, vibration, ambient light, etc.)
Do not use or mount the UXM near devices that could generate strong electromagnetic waves as it
could affect the operation of the sensor.
Do not use or mount the UXM in an environment of organic solvents, gas, or where corrosive
substances are present. Working under such environments may decrease the detection capacity of the
sensor.
2.3 Installation of UXM
Install the UXM on a firm surface or structure to avoid displacement.
Mount the sensor firmly to avoid optical axis displacement due to vibration and shock.
Shock and vibration should not loosen the mounting. Detection result will be different if the sensor is
displaced due to such condition.
Mutual interference can occur when two or more UXM sensors are mounted at the same detection plane.
Refer to chapter 5 (mutual interference and synchronous operation) for details.
When using outdoors add necessary measures to prevent from rain and/or dust accumulation on the
optical window.
When cover is used it should be of highly transparent material that does not influence detection property.
(Light wavelength 905nm)
The UXM should be mounted with a provision of sufficient space for maintenance.
Do not put any object in the detection area of the UXM. It is not possible for the sensor to detect objects

that lie behind the obstacle.
Increasing the response time will also increase the stability of the UXM. However, this will reduce the
detection capability towards moving objects. User must perform pre-operation tests before using this
function.
2.4 Wiring
Switch off all the power supplies during wiring.
When a converter is used for supplying the power, make sure it fulfills the following requirements.
・A rated output voltage within the range of DC 10V to 30V.
・Use power source with 1A or more (1.5A or more DC 15V or less) current capacity.
While using the heater additional 1A or more is required.
・The power supply complies with the requirements of electromagnetic compatibility regulations
(EMC) of the respective country, states and district.
All the input/output signal cables should be installed away from machines, power lines and high-
voltage cables.
2.5 Configuration
Pre-operation test must be performed to verify the configurations before operating the UXM.
Changes made during the configuration must be recorded and saved.
2.6 Inspection and maintenance
User must perform inspection and maintenance by referring to the following checklists provided in this
document. (Refer to chapter 9)
・Pre-operation inspection
・Operation inspection
・Daily inspection
・Periodical inspection
・Cleaning the optical window
Checklists in this document are provided as the basic guidelines while performing the test and maintenance.
User must perform additional inspection and maintenance tasks deemed necessary for the respective
application.
Stop the machine and system if faults are detected during these tests.
Clean the optical window when it gets contaminated. If the optical window is damaged it should be
replaced by a new one, therefore contact the nearest distributor or sales representative.

15 set of areas (Configurable)
Hysteresis of detection area ( 17 page)
It is possible to configure area with its origin offset from the center of scanning beam.
Easy configuration using PC installed with configuration application software (Area Designer )
Teaching function.
Minimum response time of 100ms (Configurable)
Malfunction output:Activates malfunction output according to self-diagnosis function.
Synchronize function: A maximum of 4 sensors for master/slave operation is possible ( 29 page)
ON/OFF delay function ( 15 page)
Filter function ( 19 page)
Limited detection capacity zone ( 20 page)
Minimum detection width ( 20 page)

SCIP communication protocol
UXM can be used for the following applications:
For the crane operating application, obstacle detection, position detection of container etc.
Access protection in the dangerous area, buildings (such as detection of vehicle, persons etc.)
This product is an auxiliary safeguard product only not a safety device. In the event
of a product malfunction, it could cause a serious accident so use an additional
safeguarding device such as bumpers. Also, take necessary measures such as
backup circuit etc.
