Description
The Diasafe option has not been set although ON-LINE HDF has been
selected.
– CPU 2: DIP switch array 2, switch 1 not set to ON.
CPU1 failed to stop the balancing chamber (24 sec).
– The message via the serial interface from CPU1 to CPU2 is missing.
– The current rise pulse is missing (CI, X634/A23) → X633L/C31, no
5-V pulse.
CPU1 failed to comlete one balancing chamber switching within 20 sec
(30 ml fluid not removed?).
– The message via the serial interface from CPU1 to CPU2 is missing.
– Verify the current rise pulse.
During the pressure-buildup phase, a negative pressure of less than
–370 mmHg has developed (24 sec).
– The HDF filter is clamped/clogged.
– The Diasafe valve is not open, control line (V_DSAFE, X632/B5) →
X637/C16, 0 V are missing.
After the maximum fluid volume of 255 ml +60 ml has been removed
the expected negative pressure of –220 mmHg up to 370 mmHg failed
to build up.
– Major leakage in the Diasafe/HDF filter membrane and/or filter
housing.
– Major leakage in the O-rings on filter holder/couplings.
– V26 electrically or mechanically not closed.
The negative test pressure of less than –220 mmHg has developed,
before the minimum fluid removal of 255 ml –60 ml has been achieved.
– The Diasafe/HDF filters are contaminated.
– The Diasafe/HDF filters were not correctly deaerated upon start of
the test.
– V112 electrically or mechanically not open.
The zero point for pressure measurement cannot be set. The max. test
time has been exceeded (10 min).
– Leakage in the Diasafe/HDF filter membrane and/or filter housing.
– Leakage in the O-rings on filter holder/couplings.
The negative pressure to be achieved in the test failed to stabilize
within the maximum
±13.3 mmHg/min).
– Leakage in the Diasafe/HDF filter membrane and/or filter housing.
– Leakage in the O-rings on filter holder/couplings.
– Leakage in the hydraulic system.
– V26 electrically or mechanically not closed.
