Precautions
Tighten the terminal screws to the recommended
torque of 0.5 to 0.6 N
•
m. Failure to do so may
occasionally cause physical damage due to fire.
Do not use the product in an environment with
flammable or explosive gas. Doing so may
occasionally cause minor or moderate personal injury
or physical damage due to explosion.
Do not touch the terminals while the power is ON.
Doing so may occasionally cause electric shock.
Do not open the top or side covers of the case or
remove masking seals. Doing so may occasionally
cause electric shock or physical damage to the
product.
Do not disassemble, repair, or modify the product.
Doing so may occasionally cause electric shock,
minor injury, fire, or damage to the product.
1.
Do not use, store, or transport the product in the following
environments.
• Locations exposed to direct sunlight
• Outdoor locations or locations exposed to wind or rain
• Locations with temperatures or humidity outside of the specified
range
• Locations subject to condensation
• Locations subject to sudden changes in temperature or
humidity
• Locations subject to strong vibration or shock
• Locations where the product will be exposed to water spray, oil,
or saltwater
• Locations exposed to corrosive gas (particularly sulfurous acid
gas, ammonia gas, etc.)
• Locations with excessive dust and dirt
2.
When mounting to a DIN Track, make sure that there are no loose
screws and that the product is securely mounted. If screws come
loose, the DIN Track, the product, or wiring may be shaken loose
due to vibration or shock.
3.
Use a DIN Track that is 35 mm in width (OMRON model number:
PFP-50N/-100N).
4.
When surface mounting, use M4 screws and tighten the screws to
the specified torque of 1.03 N
•
m max.
5.
Check to make sure there are no mistakes in the specifications or
wiring before turning ON the power.
6.
Make sure that the power supply voltage and the load are within
the specifications and ratings.
7.
Use the following crimp terminals for wiring.
Phoenix Contact
Connecting Cable:AI0.25-6BU (AWG24)
Other:
AI0.34-8TQ (AWG22)
AI0.5-8WH (AWG20)
AI0.75-8GY (AWG18)
8.
Do not pull on the cables.
9.
Conduct operation tests before using the product.
10.
Install an external switch or circuit breaker that complies with
applicable IEC 60947-1 and IEC 60947-3 requirements, and label
it clearly so that the operator can quickly turn OFF the power.
11.
Do not use the product in locations subject to static electricity or
electric fields.
12.
Install the product as far away as possible from devices that
generate strong high frequency or surges.
13.
To prevent inductive noise, separate the wiring for the product
from high-voltage or high-current power lines. In addition, do not
route the wiring for the product in parallel with or bundled with
power lines. Using separate conduits or ducts and shielded cables
can also be effective.
14.
Do not allow pieces of metal, wire clippings, or fine metallic
shavings or filings from installation to enter the product.
15.
Do not install the product near heat-producing devices (such as
devices with coils or windings).
16.
Do not connect anything to unused terminals.
17.
Firmly secure the connectors for Connecting Cables, Junction
Cables, Area Separators, Sensing Cables, and Terminators.
18.
Do not clean the product with paint thinners. Use commercial
alcohol.
19.
Dispose of the product as industrial waste.
20.
Be sure to touch the unit after touching the contacted metal and
discharging static electricity of the human body.
1.
Use the following OMRON products for leakage detection.
• Sensing Cable: F03-16UP-C-
@
M
• Connecting Cable: F03-21UP-CC
• Junction Cable: F03-21UP-JC
• Area Separator: F03-20UP-AS
• Terminator: F03-20UP-TC
2.
After leakage has been detected, wipe the fluid from the Sensing
Cable. If the Sensing Cable deteriorates despite being wiped off,
then replace it.
3.
Do not subject Sensing Cables, Connecting Cables, Junction
Cables, Area Separators, or Terminators to vibration or shock.
4.
When laying cable in a place where people pass through, use a
protective duct.
5.
Do not install the connectors on the Sensing Cables or the
Connecting Cables, Junction Cables, Area Separators, or
Terminators in the areas where leaks are being detected. If
chemical solution adheres to any of these, replace them.
6.
Do not install the Sensing Cable where it will be pressed against
a metal edge.
7.
Warm-up for 15 minutes min. after turning on the power.
8.
Do not bend or tightly tie up extra Sensing Cable.
9.
Be sure that you understand the manual before making device
settings. When short-circuiting the sensing line, use a
commercially available metal brush for 45 seconds min.
10.
This product detects changes in the electrical resistance of
liquids. The performance of the product specified in this document
may not be obtained for some types of liquids. Always perform
tests in advance before purchasing the product to confirm
applicability.
You must allow sufficient leeway in ratings and performance, and
provide proper fail-safe or other safety measures when using these
products in any of the following applications. Be sure also to consult
with your OMRON representative before actually attempting any of
these applications.
1.
Applications under conditions or environments not specified in
user documentation
2.
Applications for nuclear control systems, railroad systems,
aviation systems, vehicles, combustion systems, medical
equipment, amusement machines, or safety equipment
3.
Applications that may have a serious influence on lives and
property and thus require particularly attention to safety
