Fresenius Medical Care 4008 4/08.03 (TM)
Description
Three minutes before the end of the mandatory rinse in Dis I to V.
DS (BIBAG pressure switch 134) could not be opened at the beginning
of the test.
– Check pressure switch: Switching point: rated value: 100 mbar + 30
– Suction error of bicarbonate pump
– V91 constantly electrically or mechanically open
– V99/100 constantly electrically or mechanically closed
Three minutes before the end of the mandatory rinse in Dis I to V.
It is impossible to build up pressure on DS (BIBAG pressure switch
134) via V91.
– Pressure switch fails to close mechanically: check switching point.
– V91 fails to open electrically: P.C.B. LP 634: X634L/A12.
– V91 fails to open mechanically (possibly clogged)
– V130 electrically not closed: P.C.B. LP 634: X634L/ A4
– V130 fails to close mechanically (possibly clogged).
– Bibag connector leaking (check O rings)
– Sealing on the bicarbonate suction tube leaking.
– Check acknowledgement of pressure switch on P.C.B. LP 633:
X633L/A8.
– V99 constantly electrically or mechanically open.
Three minutes before the end of the mandatory rinse in Dis I to V.
It is impossible to build up pressure on DS (BIBAG pressure switch
134) via V100.
– V100 fails to open electrically: P.C.B. LP634: X634L/C13.
– V100 fails to open mechanically (possibly clogged).
– V91 constantly electrically or mechanically open
– Concentrate pump fails to pump.
– Filter (148) clogged.
– Pressure switch fails to open.
Three minutes before the end of the mandatory rinse in Dis I to V.
DS (BIBAG pressure switch 134) cannot be closed. V99 or V130 is
leaking.
– V91 fails to open electrically or mechanically.
– V99 constantly electrically or mechanically open
– V130 constantly electrically or mechanically open
– Sealing on the concentrate suction tube leaking.
– Pressure switch fails to close.
Three minutes before the end of the mandatory rinse in Dis I to V.
DS (BIBAG pressure switch 134) cannot be opened. V99 does not
open.
– V99 fails to open electrically or mechanically.
– V100 fails to open electrically or mechanically.
– Pressure switch fails to open.
– V91 electrically or mechanically open
– Filter (149) upstream of V99 clogged
