NOTE
Follow the instruction given below when designing, selection and handling your pressure switch.
♦The instructions on design and selection.
Installation, wiring, environment of use, adjustment, operation and maintenance described below
must also be followed.
♦Product specifications
•This product designed only for the measurement of pressurized air (including vacuums).
The pressurized air must contain no chemicals, synthetic oil with organic solvent, salts nor corrosive
gas.
Air that includes these substances can cause damage or malfunction of the digital pressure switch.
Verify the specifications in detail before use.
•Do not use the product for pressurized air containing plenty of condensed water.
Otherwise it can cause malfunction of the pressure switch.
When measuring the air with condensed water, install an air-dryer / drain catch before filter, and
release the condensed water regularly.
Improper draining of condensed water can result in the flow out of condensed water into the
secondary piping causing malfunction of pneumatic devices.
Use of the filter with an automatic draining function is recommended when the draining is difficult to
perform.
Refer to our manual “Pressurized Air Purifying System” for details of the quality of the pressurized air.
•Operate the pressure switch with the specified voltage.
Operation with a voltage beyond specifications can cause malfunction or damage of the pressure
switch.
Insufficient supply voltage may not drive a load due to a voltage drop inside the pressure switch.
Verify the operating voltage of the load before use.
•Use the pressure switch within the specified ranges of the measurement flow rate and under the
specified operating pressure.
Otherwise it can cause damage to the pressure switch and an abnormal measurement.
Do not apply constant pressure higher than 0.5MPa to vacuum pressure switch. (Specifications : -101
to 101kPa)
•Do not exceed the specified maximum allowable load.
Otherwise it can cause damage or shorten the lifetime of the pressure switch.
•Input data to pressure switch is not erased after power is off.
(Rewriting times: 100,000 times, Data duration: 10 years after power off.)
•Reserve a space for maintenance.
Remember to leave space for maintenance when designing the piping plan.
•This pressure switch is recognized marking only if the body initialized marking.
♦Product handling
♦Installation
•Do no drop, hit or apply excessive shock (100 m/s
2
) to the pressure switch.
Otherwise it can result in damage to the pressure switch causing failure or malfunction.
•Do not pull lead wires or lift the body with lead wires. (Tensile strength is less than 35N)
Hold the body when handing.
Otherwise it can result in damage of the pressure switch causing failure or malfunction.
•Follow the specified tightening torque
Excessive tightening torque can break the pressure switch, bracket, and mounting screws.
Insufficient tightening torque can displace the pressure switch from the original position or loosen the
mounting screws.
•When piping, apply the wrench only to the metal portion (attachment to be piped) integrated into the
piping.
Applying the wrench in other position can break the pressure switch.
