4.2.10

Even when the pressure at consumer’s side drops, it will not recover from

purge control operation.

Cable disconnected

Purge releasing

pressure too low

80psi (0.55MPa)

Adjust (See 1.6.2)

Check output voltage of

service pressure sensor

(See 3.1.8)

Output voltage normal

Service pressure

and output voltage

will not meet.

Replace it.

Not cable disconnected

Repair connection.

Repair or replace.

Faulty setting of purge

releasing pressure

(VR3)

Trouble of service

pressure sensor

Trouble of controller

Check setting of purge

releasing pressure (RV3)

Check cable connection

between service pressure

sensor and controller.

Disconnection or

faulty contact between

controller and service

pressure sensor
