Mounting/Installation
If the entering of foreign material to the fluid is possible, install the filter (5 m or less) or the
mist separator to the upstream side.
If compressed air containing condensate is used, install the air dryer or the drain catch before
the filter, and perform drainage regularly.
If regular drainage is difficult, the use of a filter with an auto drain is recommended.
Piping
Eliminate any dust left in the piping by air blow before connecting the piping to the product.
Otherwise it can cause damage to the product, malfunction or failure.
Perform function and leakage inspection after piping.
Safety cannot be assured in the case of unexpected malfunction. Disconnect the power supply and stop the fluid
supply if the equipment does not function properly or if there is leakage of fluid.
Do not use equipment or fittings that may leak or obstruct the air flow between the product and
the detection nozzle.
Wiring
The product is CE marked, but not immune to lightning strikes. Take measures against
lightning strikes in the system.
Limit of the cable tensile force is 50 N.
Do not lift or carry the product by holding the cables.
If the lead wire can move, fix it near the body of the product.
Keep wiring as short as possible to prevent interference from electromagnetic noise and surge
voltage.
Do not use a cable longer than 20 m.
Wire the DC (-) line (blue) as close as possible to the power supply.
Operating environment
Do not use the product in an environment where the product is constantly exposed to water or
oil splashes.
Otherwise it can cause failure or malfunction. Take measures such as using a cover.
Do not use in an atmosphere containing oil, corrosive gases, chemicals, sea water, or where
there is direct contact with any of these.
Even exposure for a short period of time, will have adverse effects including damage, failure, malfunction and
hardening of the cable.
Do not use the product in the presence of a magnetic field.
Otherwise malfunction can result.
Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
When the product is contained in a box for use, provide an exhaust port for constant release
of pressure to atmosphere.
If the pressure in the box is not atmospheric pressure, correct inspection will not be available and malfunction may
result.
The enclosure of the switch conforms to IP67 and that for the solenoid valve to IP65. The
pressure gauge and the regulator have open constructions. Take proper protection measures
in an environment where water splashes, oil or spatters from welding may adhere to the
product.
