Gambro AK 98 Service Manual

HCEN12630 Revision 07.2015
Program version 1.xx
AK 98™ Dialysis Machine - Functional check 245
Conditions Evaluations & Actions Error codes
Release valve open Measure venous pressure protective system,
if pressure > 10 mmHg or pressure < -10
mmHg then repeat test.
Attention
Release valve open Compare venous pressure protective system
with venous pressure control system. If the
difference is >10 mmHg then repeat test.
Attention
Release valve open Measure arterial pressure, if pressure > 10
mmHg or pressure < -10 mmHg then repeat
test.
Attention
Table 12-4. Zero pressure tests
NOTE!
If the tests fails, the test is repeated. An attention is issued for each pressure
transducer that failed the test:
548 Functional check is stopped
To continue, disconnect venous pressure transducer connector.
549 Functional check is stopped
To continue, disconnect arterial pressure transducer connector.
12.6.2.3 Negative pressure test
The measured pressure at each of the three pressure transducers shall reach below
-200 mmHg. The measured pressure at each of the three pressure transducers shall
not differ from each other more than 20 mmHg. If the Negative Pressure test fails a
technical error is generated.
Conditions Evaluations & Actions Error codes
Release valve open Any pressure transducer shows > –200
mmHg Measured pressure differ more than
20 mmHg between any pair of transducers
0117 047 000
Table 12-5.
12.6.2.4 Positive pressure test
The measured pressure at each of the three pressure transducers shall reach over
+200 mmHg. The measured pressure at each of the three pressure transducers shall
not differ from each other more than 20 mmHg. If the Positive Pressure test fails a
technical error is generated.
Conditions Evaluations & Actions Error codes
Release valve closed Any pressure transducer shows < +200
mmHg Measured pressure differ more than
20 mmHg between any pair of transducers
0117 047 001
Table 12-6.
12.6.2.5 Relay test
The relay controlling the pump and the valve is disabled. The pump is started to
generate a negative pressure. The pump shall not work and the valve shall not close.
The pressure shall not decrease.
