Specifications

1. Never use in an atmosphere of explosive
gases.
The structure of pressure switches is not intended to prevent
explosion. Never use in an atmosphere with an explosive gas
since this may cause a serious explosion.
2. Do not use in locations with sources of
surge generation.
When equipment that generates a large amount of surge (sole-
noid type lifters, high frequency induction furnaces, motors, etc.)
is located in the area around a pressure switch, there is a danger
of deterioration or damage to the switch's internal circuit elements.
Therefore, implement surge countermeasures at the sources, and
avoid the mixing and touching of lines.
3. Operating environment
Since the electronic pressure switch is basically an open type,
avoid use in locations where there is splashing of water or oil, etc.

Electronic Pressure Switch Precautions 2
Be sure to read before handling.
1. Perform maintenance regularly and confirm
normal operation.
It may otherwise not be possible to assure safety due to unex-
pected malfunction or misoperation, etc.
2. When used in an interlock circuit
When used in an interlock circuit, provide multiple interlock circuits
as a precaution against failure, and also perform regular inspec-
tions to confirm normal operation.
3. Cleaning the case
Use a soft cloth to clean the case. In case of heavy soiling, first
soak the cloth in a neutral detergent diluted with water and wring
it out thoroughly. Finish up by wiping with a dry cloth.
