The indication on the LCD changes due to static electricity.
♦Maintenance
•Before performing maintenance, make sure to turn off the power supply, stop supplied air, release
the residual air in the piping into the atmosphere, and verify that the pneumatic system is open to
the air.
Otherwise an unexpected operation of the system component can occur.
•Perform maintenance and check regularly.
Otherwise an unexpected malfunction of the system can occur due to a malfunction of the pressure
switch.
•Perform a proper functional check and leak test after maintenance.
Stop operation when an abnormality is observed such that the device does not work properly or
there is a leakage of fluid.
Otherwise an unexpected malfunction of the system component can occur.
•Release condensed water regularly.
The flow out of the condensed water to secondary piping can cause a malfunction of pneumatic
devices.
•Do not use solvents such as benzene or thinner to clean the pressure switch body.
It can damage the surface of the body and erase the indication on the body.
Use a soft cloth to remove stains. For heavy stains, use a cloth soaked with diluted neutral detergent
