Objective
Pressure test of tubing system and control of the dynamics of the pressure sensors.
Test code

3302x
Prerequisites for Test:
a)
Blood side must not be stopped by TLC or LLC.
If stopped: Message 1140 is displayed.
No timeout.
b)
If BS is not stopped HDFonline task must enable
the start of the tests. A delay occurs only with
autopriming (set pressure).
Timeout 2 min
2.
Test code = 33 to LLS
Test code = 33 back to LLC

Stop BPA
Test initialisation
33000
4.
3310x
Set BPA with ramp to delivery rate 200 ml/min,
opened SAKV
Timeout 90 s since subcode 100
Test SAKV opened
33001
5.
Test of BPA delivery rate at 185 ml/min < BPA < 215
ml/min
Acknowledge by closing SAKV and saving PV
33013
6.
Test of BPA motor speed
(Note: the motor pulses are used for alarm evaluation
when detecting standstill.)
33014
7.
3330x
Wait for PV > +400 mmHg for 500 ms during the
running of BPA.
Pressure reached:
-
Stop BPA, close SAKV, open VBT
-
Initialise mean value storage for PA, PV, PBS and
PBE
Timeout 90 s since the start of subcode 100
Wait for PV > 390 mmHg
no timeout
33015-
33023
8.
3340x
Evaluate every 250 ms continuous mean value from
the 4 values of PA, PV, PBS and PBE.
Evaluate after 2.5 s mean values of PBS and PBE:
PBE connected, if
PBE mean value is min. 100 mmHg higher (from BS
pressure test) than PBE mean value (from BS equality
test of pressure sensors) and PBE and PV mean value
deviate less than
±
40 mmHg (from BS equality test).
PBS connected, if
PBS mean value is min. 100 mmHg higher (from BS
pressure test) than PBS mean value (from BS equality
test of pressure sensors) and PBS and PV mean value
deviate less than
±
40 mmHg (from BS equality test).
|PA - PV|

PBE present, if:
PBE
≥
PBE +100 mmHg from test 32, step 4
PBS present, if:
PBS
≥
PBE +100 mmHg from test 32, step 4
Terminate if PBS not present for SNCO
PV
≥
PV + 100 mmHg from test 32 step 20

3340x
Wait for inversion of LLS_SELFTESTBIT from LLS
(Timeout 35 s since start of subcode 400)
