Maintenance Manual
9. Priming detector calibration
9.1 Start the AK 95 S, enter the Service menu
and select Calibrations.
9.2 Select Transducer, External and PRIMING
DETECTOR from the selection diagram.
9.3 Press "Select" to start the calibration
routine.
9.4 Insert an empty tube in the priming
detector and press "Select".
Use the normal tube from the bloodline.
9.5 The calibration is now done automatically
and the calibration factor is written into
the EEPROM.
9.6 When the info. display shows "EEPROM
STORAGE COMPLETED", the calibration
is completed.
9.7 Press "Hold" to exit.
Note! If a technical error is detected, the
calibration must be restarted, or the
priming detector replaced.
10. Measure the power on battery B1 on the
Protective driver board, exchange if the
value is below 2,6 V (Note! The machine
must be switched on when measuring).
11. Control of the blood pump occlusion
Check surface on the roller at the pump
rotor, if it is damaged exchange the unit.
The roller unit should easily go back to
upper end position when it has been
pressed down to end position, exchange
unit if it gets stuck in any position.
Note! If the blood lines have a different
wall thickness, the occlusion of the blood
pump must be adjusted to the right size.
Use the gauge pins (stop/go) available in
the kit K40158001. The kit includes
following three different gauge pins:
T = 1.1 (Stop pin = 1.1*2*0.7 = 1.5mm)
T = 1.6 (Stop pin = 1.6*2*0.7 = 2.2mm)
T = 2.0 (Stop pin = 2.0*2*0.7 = 2.8mm)
T = wall thickness of the blood tubing
5:10
Use following formula to calculate which
gage pin to use:
2 * wall thickness * 0,7 (mm)
Check the range between the blood pump
rollers and the path according to the
picture below.
= Measuring
Adjust range between the blood pump
rollers and the path if it is necessary.
The GO pin should barely pass within the
calibrating area.
The STOP pin is NOT allowed to pass in
any point within the calibrating area.
Note! Put grease on the GO and STOP
pins when not used and store gage in
plastic bag to prevent it from corroding.
Note! The gauge pins can also be ordered
separately:
T=1.1 (white) K40158002
T=1.6 mm (red) K40158003
T=2.0 mm (blue) K40158004
