Safety Precautions
■ General Cautions
• At startup and during operation, be sure to monitor the functions and
performance of the DL-RS1A.
• Provide appropriate safety measures to avoid any damage in the event that
a problem occurs.
• Do not modify the DL-RS1A or use it in any way other than described in the
specifications. The functions and performance of products used or
modified in this way cannot be assured.
• When the DL-RS1A is used in combination with other instruments, its
functions and performance may be degraded, depending on the operating
conditions and surrounding environment. Use the DL-RS1A after fully
studying the effects of combined use with other instruments.
• Do not use the DL-RS1A for the purpose of protecting the human body.
• Do not expose the DL-RS1A and peripheral devices to sudden
temperature changes. This may cause condensation, damaging the
equipment.
● Proper environment and conditions
To use the DL-RS1A properly and safely, do not install the DL-RS1A in
locations with the following conditions. Use of this equipment in an
improper environment may cause equipment failure.
•
Locations with high humidity, a large amount of dust, or poor ventilation
• Locations where the temperature rises excessively due to direct
sunlight, etc.
• Locations where corrosive or flammable gas exists
• Locations where the DL-RS1A is directly subjected to vibration or
impact
• Locations where water, oil or chemicals may splash the DL-RS1A
• Locations where static electricity is easily built up
● Noise countermeasures
Installation near a source of noise such as a power source or power cable
may cause a malfunction or failure in the equipment. Adopt appropriate
countermeasures against noise by using a noise filter or wiring cables in
separate ducts, attaching insulation to the sensor amplifier or the sensor
head, etc.
