After the valves ONL1 to 3 opened, the pressure drop in the system
was insufficient (∆P < –100 mmHg).
– Valve ONL1/ONL2/ONL3 electrically or mechanically not open
– Kinked tubing
– HDF filter strongly contaminated
No pressure change of ∆P > 40 mmHg within 15s.
– HDF filter membrane leaking (major leakage)
– No HDF filter installed
Insufficient test pressure (P < 750mmHg) in the system.
– HDF filter membrane leaking (major leakage)
– No HDF filter installed
– Hydraulics system leaking
After the valve V189 opened, the pressure drop in the system was
insufficient (∆P < –70 mmHg).

– Diasafe filter strongly contaminated
– Filter before/after V43 strongly contaminated
Pressure increase in the system fails to exceed P > 760 mmHg.
– Diasafe filter membrane leaking (major leakage)
– No Diasafe filter installed
Pressure holding test failed to be passed. Excess pressure drop within
a measurement time of 30s (∆P > –10 mmHg).
– Diasafe and/or HDF filter membrane leaking

Fill phase has been stopped.
Valve(s) V26 open and/or V24, V24b closed (according to electronic
acknowledgement), or failure to perform 25 or 15 balancing chamber
switchings within 120s.
– Valve control failed
– Balancing chamber switchings failed (e.g. only "Eigentakt")
Valve(s) ONL1, 2 or 3 closed and/or V24 open or port 1 or 2 open during
the rinse phase (according to electronic acknowledgement).
