•Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, shade the product from the sunlight.
Otherwise failure or malfunction can result.
•Keep within the specified fluid and ambient temperatures range.
The fluid and ambient temperatures is 5 to 50
damage or operation failure due to frozen moist in the fluid or air.
Protection against freezing is necessary. Air dryer is recommended for elimination of drain and water.
Avoid sudden temperature change even within specified temperature.
•Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
•Use operating fluid which does not corrode the part in contact with fluid which is made of SUS630 (for
sensing part) or SUS304 (for fitting part).
(Compatibility between fluid and material can be checked by contact to fluid supplier.)
•When resin piping is used, depending on the fluid, static electricity may occur. When connecting the
switch and sensor, please take adequate anti-static electricity measures on the equipment side, and do
not use with a grounding that is shared with equipment that generates strong electromagnetic noise or
high-frequency waves. This can result in a switch or sensor being damaged by static electricity.
∗Adjustment and Operation
•Turn the power on after connecting a load.
Otherwise it can cause excess current causing instantaneous breakage of the Pressure switch.
•Do not short-circuit the load.
Although error is displayed when the Pressure switch load is short circuit, generated excess current lead to cause
the damage of the Pressure switch.
•Do not press the setting buttons with a sharp pointed object.
It may damage the setting buttons.
•If using the product to detect very small pressure rates, warm up the product for 10 to 15 minutes first.
There will be a drift on the display and the analogue output of approximate 1% immediately after the power supply
is turned on.
•Perform settings suitable for the operating conditions.
Incorrect setting can cause operation failure.
For details of each setting, refer to page
•Do not touch the LCD during operation.
The display can vary due to static electricity.
∗Maintenance
•Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of
air before performing maintenance.
There is a risk of unexpected malfunction.
•Perform regular maintenance and inspections.
There is a risk of unexpected malfunction.
•Perform drainage regularly.
If condensate enters the secondary side, it can cause operating failure of pneumatic equipment.
•Do not use solvents such as benzene, thinner etc. to clean the Pressure switch.
They could damage the surface of the body and erase the markings on the body.
Use a soft cloth to remove stains. For heavy stains, use a cloth soaked with diluted neutral detergent and fully
squeezed, then wipe up the stains again with a dry cloth.
