V130 Failure
V188 Failure
F14
Description
Three minutes before the end of the mandatory rinse in Dis I to V.
The pressure switch PSW_102 (S123) (concentrate) did not open after
pressure reduction.
– Pressure on distribution piping > 500 mbar (according to specifica-
tion, the permissible pressure is max. 500 mbar). Pressure peaks on
distribution piping: Frequently occurs in distribution pipings with
user points if e.g. several patients are disconnected simultaneously
and disinfection is started.
– Switching point of pressure switch too low:
desired value = 700 mbar ± 20 mbar
– Membrane pumps fail to run
– V102 fails to open electrically or mechanically
– Check acknowledgement of pressure switch on P.C.B. LP 633:
X633L/ A20
Three minutes before the end of the mandatory rinse in Dis I to V.
V91 or V100 cannot be opened.
– V91 or V 100 fail to open electrically:
P.C.B. LP 634: V91 = X634L/A12; V100 = X634L/C13
– V 91 or V 100 mechanically not open:
check sieve (148) upstream of V100, or valves clogged
– V99 constantly open (electrically P.C.B. LP 634: X634L/B12 or
mechanically)
– V 102 not open
– Pressure switch for PSW_102 (S 123) fails to switch
Three minutes before the end of the mandatory rinse in Dis I to V.
V99 cannot be opened.
– V 99 fails to open electrically:
P.C.B. LP 634: X634L/ B12.
– V 99 fails to open mechanically:
check sieve (149) before V99, or V99 clogged.
– Pressure switch for PSW_102 (S 123) fails to open.
Three minutes before the end of the mandatory rinse in Dis I to V.
V130 cannot be opened (applicable to machines with BIBAG only).
– V130 electrically defective:
P.C.B. LP 634: X634L/ A4
– V130 mechanically defective or clogged
– Pressure switch for PSW_102 (S 123) fails to open.
– Check tubing for bicarbonate suction line and bibag block.
V188 fails to open.
– V188 electrically defective.
– V188 mechanically defective or clogged
– Pressure switch for PSW_102 (S123) fails to open.
Shortly before the end of the mandatory rinse in Dis I to V (CDS: Dis I to
IV).
The hydraulics test has not been completed correctly, possibly caused
by flow problems.
