10.4 Device-specific errors
The following table supports you during diagnosis and provides information on the necessary spare
parts, where applicable.
Depending on the degree of difficulty and measuring media available, diagnosis is carried out by:
• Specialized staff of the owner-operator
• Electrical technicians of the owner-operator
• System creator/operator
• Hauser Service
Information on the exact names for spare parts and the installation of these parts is found in the
"Spare parts" section.
Assembly moves several
times without correct
feedback
Pneumatic connections mixed up
See "Pneumatics and hydraulics, CPG"
section.
• Hose 2 "Measure" at valve 5 at front
• Hose 3 "Service" at valve 5 at rear
Feedback not correctly connected See "Pneumatics and hydraulics, CPG"
section.
• Hose 5 "Measure feedback" (term.
11/12)
• Hose 6 "Service" feedback (term. 13/14)
Feedback switch misaligned Feedback switch under pressure
• Open: Term. 11/12-13/14 = 14 V
• Closed: Term. 11/12-13/14 = 0 V
Assembly was moved manually.
Feedback signal is thus undefined.

persists, check installation or have checked
by Hauser service.

Voltage incorrect/too high
Compare line voltage and information on
the nameplate.
