Safety Precautions
Other
●Always observe the following items.
1.
When using this product in pneumatic systems, always use
genuine Koganei parts or compatible parts (recommended parts).
When doing maintenance or repairs, always use genuine Koganei
parts or compatible parts (recommended parts).
Always follow the designated procedures and methods.
2.
Never do inappropriate disassembly or assembly of the product
related to basic construction, performance, or functions.
3.
Sensor heads are for use with non-corrosive gas. Do not use it for
liquids or corrosive gas.
4.
Check the power fluctuation to ensure that the input power does
not exceed the rated value.
5.
Avoid use during the transitional state (0.5 seconds) when the
power is turned on.
6.
Do not insert wires from the detection ports of the sensor heads.
Doing so may damage the diaphragm and cause it to be unable to
operate normally.
7.
Never use a needle or any other sharp pointed object to perform
key operations.
Koganei cannot be responsible if these items are not properly observed.
●
Do not use the product in locations subject to direct sunlight (ultraviolet
radiation); in locations subjected to high temperature or humidity; in
locations where dust, salt, or iron particles are present; or in locations
with media and/or an ambient atmosphere that includes organic
solvents, phosphate ester type hydraulic oil, sulfur dioxide gas, chlorine
gas, acids, etc. It could lead to early shutdown of some functions, a
sudden degradation of performance, and a reduced operating life. For
information about materials, see Major Parts and Materials.
●
Do not apply an external magnetic field to the product while it is operating.
Unintended operations could damage equipment or cause injury.
●
Make sure that the polarity of wiring connections is correct.
Incorrect polarity could result in damage to the product.
●
Pressure sensor heads could be damaged by static electricity if you
touch them with your hand while they are energized.
CAUTION
●
When installing the product, leave room for adequate working space
around it. Failure to ensure adequate working space will make it
more difficult to conduct daily inspections or maintenance, which
could eventually lead to system shutdown or damage to the product.
●
Do not scratch, dent, or deform the product by climbing on it, using it as a
step, or placing objects on top of it. It could result in damaged or broken a
product that results in operation shutdown or degraded performance.
●
Always post an “operations in progress” sign for installations,
adjustments, or other operations, to avoid unintentional supplying of
air, electrical power, etc. Unintended power supply can cause electric
shock and sudden operation, creating the risk of personal injury.
●
Depending on the product, unintended operations may occur when
a leakage current occurs in the control circuit. Use countermeasures
for circuit leakages in the control circuit so as not to exceed the
allowable leakage current values for the product's specifications.
●
Use only sensor heads that satisfy the specifications of the sensor
controller with multi-channel multi-sensor controllers.
Using one that is outside the specifications causes erratic operation.
●
Use the correct tightening torque to mount sensor heads.
Over-tightening beyond the allowed tightening torque may damage the
mounting threads or sensor head, etc. However, insufficient tightening
torque may cause leaks or shifts in the sensor head position, resulting in
unstable operation. Refer to “Instruction Manual” for the tightening torques.
●
While handling multi-channel multi-sensor controllers or sensor heads,
do not subject them to excessive shock (over 490 m/s
2
[50 G]) by hitting,
dropping, or bumping them. Even if the product appears undamaged,
damage to internal components can cause abnormal operation.
●
Avoid short circuiting the loads. Turning a sensor’s output on while
the load is short-circuited causes overcurrent, which will damage
the sensor head instantly. Furthermore, even with multi-channel
multi-sensor controllers, turning on SW output while the load is
short-circuited may damage the products due to over current.
Example of short-circuit load:
Output lead wire for sensor output (SW output)
is directly connected to the power supply.
ATTENTION
●
When considering the possibility of using this product in situations or
environments not specifically noted in the Catalog or Owner’s
Manual, or in applications where safety is an important requirement
such as in an airplane facility, combustion equipment, leisure
equipment, safety equipment, and other places where human life or
assets may be greatly affected, take adequate safety precautions
such as an application with enough margins for ratings and
performance or failsafe measure. Be sure to consult us about such
applications.
●
Use a protective cover, etc., to ensure that human bodies do not come
into direct contact with the operating portion of mechanical devices, etc.
●
Do not control in a way that would cause workpieces to fall during power failure.
Take control measures so that they prevent the workpieces, etc., from
falling during power failure or emergency stop of the mechanical devices.
●
When handling the product, wear protective gloves, safety glasses,
safety shoes, etc., to keep safety.
●
When the product can no longer be used, or is no longer necessary,
dispose of it appropriately as industrial waste.
●
Pneumatic equipment can exhibit degraded performance and
function over its operating life. Always conduct daily inspections of
the pneumatic equipment, and confirm that all requisite system
functions are satisfied, to prevent accidents from happening.
