Operating Environment
- Do not use in an environment where corrosive gases, chemicals, sea water, water or steam are
present. These can cause failure or malfunction.
- Do not use the product in a place where the product could be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant or
cleaning solvent, even for a short time, it may be adversely affected (damage, malfunction, or
hardening of the lead wires).
- Keep the ambient temperature of the product between 5 and 50°C. In environments such as
inside a panel where heat radiation efficiency is poor, the ambient temperature will rise due to
the heat generation of the coil of the solenoid valve, causing malfunction. At the same time,
avoid rapid temperature changes even within the specified temperature range.
- Do not use this product in places where there are cyclic temperature changes. Heat cycles other
than ordinary changes in temperature can adversely affect the inside of the product.
- Do not use where the product is exposed to direct sunlight. Shade the sunlight in locations
where the product is exposed to direct sunlight. Failure and malfunction can result.
- Do not use in a location where the product is exposed to radiant heat from surrounding heat
sources. This can cause operating failure.
-Do not use the product in an area where surge is generated. When there are machines or
equipment that generate large surge near the pressure switch (magnetic type lifter, high
frequency inductive furnace, motor, etc.), this can result in deterioration and damage of the
internal elements. Take measures against the surge sources, and prevent the lines from coming
into close contact.
- Do not let foreign matter, such as wire debris, get inside the product. In order to avoid failure and
malfunction, do not let foreign matter, such as wire debris, get inside the product.
- The use of resin piping can cause static electricity to be generated, depending on the fluid.
Therefore, when connecting the vacuum pressure switch assembly, take appropriate measures
against static electricity at the customer’s equipment side, and separate the grounding for the
product from the grounding for any equipment which generates a strong electromagnetic noise
or high frequency. Otherwise, static electricity can break the vacuum pressure switch assembly.
