2.1.2 Safety Precautions on Laser Product
If the product is not used, controlled or adjusted as specified herein, or
operations steps are not performed as specified herein, hazardous radiation
exposure may be caused. Follow the instructions mentioned in this manual.
Otherwise, injury to the human body (eyes and skin) may be resulted.
Precautions on Class 2M Laser Product
Do not stare into the direct laser beam or specularly reflected beam.
Do not direct the beam at other people or into areas where other people
might be present.
Be careful of the path of the laser beam. If there is a possibility that the
operator may be exposed to the specular or diffuse reflections, block the
beam by installing a protective cover.
Install this product in such a way that the path of the laser beam is not as
the same height as that of human eyes.
Viewing the laser output with certain optical instruments (for example,
eye loupes, magnifiers and microscopes) within a distance of 100 mm may
pose an eye hazard.
Precautions on Class 2 Laser Product
Do not stare into the direct laser beam or specularly reflected beam.
Do not direct the beam at people or into areas where people might be
present.
Be careful of the path of the laser beam. If there is a possibility that the
operator may be exposed to the specular or diffuse reflections, block the
beam by installing a protective cover.
Install this product in such a way that the path of the laser beam is not as
the same height as that of human eye.
Do not disassemble this product. Laser emission from this product is not
automatically stopped when it is disassembled.

2.2 Important Instructions
Observe the following cautions to prevent malfunction of the SR Series 3D Camera and
to ensure that it is used properly.
2.2.1 Precautions for Use
Use this instrument at the correct supply voltage. Failure to do so may cause
fire, electric shock, or a product damage.
Do not disassemble or modify this instrument. Doing so may cause fire and
electric shock.
Attach the camera to a metal plate for use. The camera surface temperature may
increase, which may cause burn injuries.

CNSSZN Technology Ltd.
www.cnsszn.com
15/63
Hardware Manual of SR Series © 2021 SSZN All Right Reserved
The power of the controller and peripherals connected to this controller must
be turned off when the camera cable is plugged or unplugged. Failure to do so
may cause product damage.
Do not connect or disconnect the display unit and the controller while the
power is on. Failure to do so may cause a product damage.
Do not turn off this product while this product is writing data to memory, for
example, when settings are being modified. Failure to do so may cause loss of a
part of or all of the setting data.
The USB connector and a part of the input/output terminals are not insulated
from the DC24V (-) terminal. Exercise caution not to produce a potential
difference between the non-insulated terminals due to a positive grounding or a
potential difference between devices. Otherwise, it may cause a malfunction in
the controller or a malfunction in the connected computer or other external
device.
We recommend backing up the settings with EdgeImaging in case there are
problems with the product.
A change in the ambient temperature may cause the measurement to fluctuate.
Be sure to keep the temperature stabilized. When the ambient temperature
changes by 10 ℃, the product takes 60 minutes to achieve uniform internal
temperature distribution.
Wait approximately 30 minutes after the power is turned on before using the
SR Series 3D Camera. Otherwise, the measured value may gradually fluctuate
because the circuit is not immediately stable after the power is turned on.
Do not operate this product near lighting fixtures. If the product must be used
in such a location, install a light shielding board or similar device so that the
light will not affect the measurement.
When the target is vibrating, the measured value may fluctuate. In this case,
increase the averaging of the profiles and the measurement averaging to
achieve a more accurate value.
Due to the slow flow of air, the measured values may be deviant. In this case,
take the following countermeasures.
Project the measurement area with a protective cover.
Agitate the air between the measurement point and the workpiece more
strongly with a fan.

2.2.2 Precautions in Emergency
Turn the power off immediately in the following cases. Using the product in an
abnormal condition could cause fire, electric shock, or accident.
Contact the SSZN office for repair.
If liquid, including water or chemicals, or debris enters the controller.
If the product is dropped or the case is damaged.
If abnormal smoke or odor is present.
2.2.3 Precautions on Installation
To use this instrument correctly and safely, avoid installing it in the following
locations. Installation in such locations may cause malfunction.
Locations that are humid, dusty or poorly ventilated.
Locations where the temperature is high, such as those exposed to direct
sunlight.
Locations where there are flammable or corrosive gases.
Locations where the product may be subject to vibration or impact.
Locations where water, oil, or chemicals may splash onto the product.
Locations that are prone to static electricity.
Installing the product in the vicinity of an electrical noise source such as a
power source and high-voltage line could cause malfunction and product
damage due to noise. Take preventive actions such as using noise filters,
separating cables, and insulating the controller and the camera. Use
single-conductor shielded cable as the analog output cable.
In the following cases, foreign matters such as dust and debris or water and oil
could cause differences in the measurement values.
Adhesion on the protective glass: Blow the dirt off with clean air. If dirt
persists, wipe the glass surface gently using a soft cloth moistened with alcohol.
Adhesion on the surface of the measuring target: Blow the dirt off with clean
air or wipe it off.
Intrusion of floating or sprinkled dust or dirt into the light-axis range: In this
case, take corrective action with a protective cover or air purge.
