Present options and DIP switch settings do not match.
CPU1 machine status (MST), HPU status and DIP switch/Array2
changed during the test running time.
– ONLINE plus:
CPU 2: Array 2, DipSw2 not set to OFF
CPU 2: Array 2, DipSw3 not set to ON
– DIASAFE plus:
CPU 2: Array 2, DipSw2 not set to OFF
CPU 2: Array 2, DipSw3 not set to OFF
– MST transmitted by CPU1 not matching with the set DIP switch of
array 2.
– DIP switch/Array2 changed while the test was in progress.
– HPU logged off.
Pressure holding test not passed. Max. number of treatments exceed-
ed?
– Diasafe and HDF filter membranes leaking/worn.
Dialysate outlet pressure (DA1) outside the permissible range (10s).
DA1 test range: –125mmHg ≤ P_dial ≤ 55 mmHg
– Acknowledgement DA 1 (P_DIAL, X633L/B6) → X632/A29
– Acknowledgement line DA 2 (see HPU diagram)
Cross comparison of both pressure transducers (DA1 / DA2) is outside
the acceptable tolerance (10s).
P(DA2) == P(DA1) ±20mmHg
– Acknowledgement DA 1 (P_DIAL, X633L/B6) → X632/A29
– Acknowledgement DA 2 (see HPU diagram)
The test valve V183 is leaking. Pressure increase in the system of
∆P(DA2) > 30 mmHg within 4s.
– V183 open, contaminated, or mechanically defective
– HPU, output stage etc. defective
No pressure increase of ∆P(DA2) > 200 mmHg within 4s after opening
the test valve V183 in the system.
– V183 fails to open or mechanically defective.
– Air pump defective, is not running
– HPU, V183 and/or air pump output stage etc. defective
