Supervisor alarm tone buzzer
The test includes the successive activation of all four alarm tones.
Supervisor alarm buzzer
Continuous alarm tone
The supervisor system activates the buzzer for 2 s.
The user is responsible for checking whether the buzzers function correctly.
Self-test
Dynamic T1 Tests by the Controller
Weight deviation by the plasma/buffer pump
Verification after activation of step 4 of the priming and rinsing phase whether
the weight increase on the load cell corresponds to the delivery rate of the
plasma/buffer pump (65 ml/min).
For a duration of 30 s, the weight increase must be higher than 20 g and less than
40 g, otherwise alarm A26 will be initiated and the test sequence has to be
repeated
Step 4
Priming and
rinsing
A26
HAK leakage test
Verification in step 6 of the filling and rinsing phase whether the HAK can be
closed and the plasma line is inserted properly into HAK.
For a duration of 10 s pressure increasing of PDPA must be > 60mmHg with a
running Plasma pump (30 ml/min) and closed HAK, otherwise alarm A33 will be
initiated. Before the test or before repeating the test the PPF pressure is reduced
to below 150 mmHg automatically (if necessary).
Step 6
Priming and
rinsing
A33
DAD Test
Verification at the beginning of step 9 of the filling and rinsing phase whether
fluid is recognized at the beginning of dialysate line filling and DAD sensor works
properly.
The sensor must detect fluid within 20 s after the start of the filling process of
the dialysate line running with 200 ml/min flow, otherwise alarm A28 will be
initiated.
Step 9
Filling and rinsing
A28
Weight deviation by the dialysate pump
After a successful DAD test, verification in step 9 of the filling and rinsing phase
whether the weight decrease on the load cell corresponds to the delivery rate of
the dialysate pump (100 ml/min).
For a duration of 20 s the weight decrease must be higher than 20 g and less than
46 g, otherwise alarm A27 will be initiated and the test is performed once again.
Afterwards the filling and rinsing phase continues.
Step 9
Filling and rinsing
