4.3.1 Pressure Switch Unit
The pressure switch unit supplies protective air or gas to the manipulator
to prevent explosive gas from entering the manipulator. Usually, the unit is
installed on the side of the DX200.
The circuit diagram and dimensions are shown in
Circuit of the Pressure Switch Unit”
Set the air pressure so that the pressure shown on the pressure gauge of
each pressure reducing valve to be within the pressure ranges shown in
