2. Safety precautions

Make sure to read the following safety precautions for the correct use and operation of the UST.

2.1 General precautions


The UST is not a safety device. Do not use this sensor for the purpose of protecting humans.

The UST uses laser radiation for detecting objects within configured area.

Perform pre-operation tests in order to verify the performance of the UST.

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 UST within the specifications described in this user's manual. Perform necessary
maintenance to prevent deterioration of UST's detection capability (refer to chapter 8)

Do not modify or disassemble the UST. This could compromise the IP65 housing rating. Such
modifications will void the warranty.

The detection capability of the UST will decrease if dust covers the optical window. Regular cleaning of
the optical window is necessary while working under dusty

The UST should be disposed as industrial waste or in accordance with the local disposal directives.

2.2 Operating environment


This product is for indoor use only.

Make sure that the UST's operating environment is within the stated specification (temperature,
humidity, vibration, ambient light, etc.)

Do not use or mount the UST near devices that could generate strong electromagnetic waves as it
could affect the operation of the sensor.

Do not use or mount the UST in dusty, smoky, or misty environments, or where corrosive substances
are present. Working under such environments may decrease the detection capacity of the sensor.

2.3 Installation of UST


Install the UST on a firm surface or structure to avoid displacement.

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 UST sensors are mounted at the same detection plane.
Refer to chapter 5 (mutual interference and synchronous operation) for details.

The UST should be mounted with a provision of sufficient space for maintenance.

The UST should be mounted where indicator lamps are easily visible.

Do not put any object in the detection area of the UST. It is not possible for the sensor to detect objects
that lie behind the obstacle.

Do not add any protective materials such as glass, transparent cover, etc. in the front of the optical
window. This may lead to loss of detection capability of the UST.
