3. How to Order
•
Do not disassemble, modify (including change of printed circuit
board) or repair the product.
An injury or product failure may result.
•
Do not operate the product beyond the specification range.
Fire, malfunction or equipment damage may result. Use the product
only after confirming the specifications.
•
Do not use the product in the presence of flammable, explosive
or corrosive gas.
Fire, explosion or corrosion may result. This product does not have an
explosion proof construction.
•
When using the product as part of an interlocking system:
1) Provide a double interlocking system, for example a mechanical
system.
2) Check the product regularly to ensure proper operation.
•
Before performing maintenance, be sure of the following:
1) Turn off the power supply.
2) Stop the air supply, exhaust the residual pressure and verify the
release of air from the system.
• Always perform a system check after maintenance.
Do not use the product if any error occurs.
Safety cannot be assured if caused by un-intentional malfunction.
• Provide grounding to ensure correct operation and to improve
noise resistance of the product.
This product should be individually grounded using a short cable.
•
Follow the instructions given below when handling the product.
Failing to do so may result in product damage.
• Maintenance space should always be provided around the product.
• Do not remove labels from the product.
• Do not drop, hit or apply excessive shock to the product.
• Follow all specified tightening torques.
• Do not bend, apply tensile force, or apply force by placing heavy
loads, on the cables.
• Connect wires and cables correctly, and do not connect while the
power is ON.
• Do not route wires and cables together with power or high-voltage
cables.
• Check the insulation of wires and cables.
• Take proper measures against noise, such as noise filters, when the
product is incorporated in equipment or devices.
• Select the required protection (IP) rating according to the environment
of operation.
• Take sufficient shielding measures when the product is to be used in
the following conditions:
(1) where noise due to static electricity is generated.
(2) where electro-magnetic field strength is high.
(3) where radioactivity is present.
(4) where power lines are located.
• Do not use the product in a place where electric surges are generated.
• Use suitable surge protection when a surge generating load such as a
solenoid valve are to be directly driven.
• Prevent any foreign matter from entering this product.
• Do not expose the product to vibration or impact.
• Use the product within the specified ambient temperature range.
• Do not expose the product to any heat radiation.
• Do not clean the product with chemicals such as benzene or thinners.
Follow the instructions given below when handling your digital pressure
switch. Otherwise, the switch may be damaged or may fail, thereby
resulting in malfunction.
• Do not pull the lead wire with force nor lift the switch by holding the lead
wire. (Tensile strength: less than 49N.)
• Connect the terminal FG to ground when using a switching regulator
obtained on the commercial market.
• Insert a noise filter (line noise filter and ferrite core or other elements)
between the switching regulator and this digital pressure switch when ana-
logue output is used.
• Do not use with corrosive or flammable gas or liquid.
• Do not press the setting buttons with a sharp pointed object.
• Do not rub the LCD indicator during operation (the display may change due
to static electricity.)
• When performing piping, tighten the pipe by using a spanner on the hexagon
section of the attachment of the digital pressure switch (Do not apply force on
the switch body).
• Do not use this digital pressure switch in areas that are exposed to water,
oil or chemicals (open-type specification).
When the 0X or 0XY type (with filter) is used
• If the filter element (ZX1-FE) is clogged, stop operation and replace the ele-
ment.
