Maintenance Manual

AK 95 / AK 95 S

HCEN12189 Rev.10

. 2006

Actions to carry out after the parts
have been exchanged

Base-kit

1.

Check that the screws for the blood pump
are tightened. (Both inside the BM and
behind the blood pump rotor)

2.

Check that the screws for the hose clamps
on the water inlet and drain tube are
tightened.

3.

Check that the wheels are tightened.

4.

Perform the Protective Earth Test (PET)
according to instructions available in
HCEN12190, Electrical safety inspections
for AK-machines.

5.

Check the protective earth resistance:

Measure between TP 5 (Z0VL) on the
control CPU board and the metal on the
heater rod.
Measure in

M

Ω

,

should be > 1 M

Ω

. The

machine must be empty and switched off
during measurement.

Note!

Mount the blood monitor on the

fluid monitor.

6.

Erase the error code buffers. Enter service
menu > Diagnose > System > Errors >
Erase.

7.

Calibrate the A/D converters for AK 95 S,
see chapter "Calibrations" in the Service
manual.

8. BPM-test

Note!

Following text is valid for machines equipped
with the SunTech blood pressure module
(K24274001). For machines equipped with the
Colin blood pressure module (K23564001), refer
to HCEN9095, revision 10.2005 for technical and
maintenance information about BPM.

8.1 Test method:

-

Attach BPM cuff, 100900141, tight to the
BPM
test equipment, K22151001.

-

Start the AK 95 S with the main switch
and the ON/OFF button.

-

Enter Service mode.

-

Enter Diagnostics mode.

-

Select BM, Others, BPM

8.2 BPM sub-tests

In the BPM service menu the following sub-tests
are included:
- Air leakage test: measures that the equipment
is airtight.
- Inflation speed test: measures the time to fill
the cuff with air.
- Static pressure: Check of pressure transducer
calibration

Each of the tests can be carried out separately
but the above order for carrying out the sub-tests
is recommended.

Check that the results from the sub-tests not
exceed following limits:
- Air leakage: maximum 18 mmHg/ 3 min
- Inflation speed: 2 -11 s
- Static pressure: Maximum deviation from
reference to be within ± 3 mm Hg.

50 ± 3 mmHg
150 ± 3 mmHg
250 ± 3 mmHg
