9.3 Maintenance and Inspection of the Pneumatic Unit
9.3.1 Solenoid Valve
Check if the air purge starts a few seconds after turning ON the power to the NX100 and if it ends
approximately 8.5 minutes later.
9.3.2 Pressure Reducing Valve
Measure the air pressure for the pneumatic unit with a pressure gauge. Remove the test plug or the
relief valve on the pneumatic unit and connect the gauge. The air pressure must always be from
0.02 MPa (0.2 kg/cm
2
) to 0.04 MPa (0.4 kg/cm
2
) under normal conditions and from 0.3 MPa
(3.0 kg/cm
2
) to 0.45 MPa (4.5 kg/cm
2
) when purging.
