Bl- 6.0.0 Blood Leak Alarm Will Reset?; Bl- 6.1.0 Clean/Calibrate Blood Leak Sensor #8; Bl- 6.2.0 Calibrate Blood Leak Sensor #8 - Fresenius Medical Care 2008K2 Troubleshooting Manual

BL- 6.0.0 BLOOD LEAK ALARM WILL RESET?

Press and release the 'RESET' key up to three (3) times in twenty (20) second intervals. TWO (2) possible
scenarios below:
1) IF the Blood Leak alarm CAN be cleared: The most likely cause of a false blood leak alarm is "air in
dialysate" possibly caused when priming a dialyzer or moving the lines between the shunt and the
dialyzer. If SURE there is no air flowing through the Blood Leak Sensor see procedure number
BL- 6.1.0 (page 520).
2) IF the Blood Leak alarm cannot be cleared: See procedure number
BL- 6.1.0 CLEAN / CALIBRATE BLOOD LEAK SENSOR #8
a) Turn the machine OFF!
b) Using ESD precautions push down HARD on ALL circuit boards in the card cage. After reseating
ENSURE they are locked in!
c) ENSURE the Sensor and Actuator board ribbon cables are plugged in SECURELY
IMPORTANT!
d) Perform ACID CLEAN followed by BLEACH DISINFECT to ensure the Blood Leak
Detector's glass tube is clean of bicarb residue!
WARNING!
Calibrating Blood Leak without first performing a Bleach Disinfect may lead to
unnecessary parts replacement and / or cause an inaccurate Blood Leak calibration!
e) See procedure number

BL- 6.2.0 CALIBRATE BLOOD LEAK SENSOR #8

a) Place the machine into Service mode → Calibrate Sensors → Blood Leak Detector.
b) Press 'CONFIRM' to start the calibration then see part c.
c) NORMALLY the calibration, one at a time, takes the screen's Leak then Dimness windows to
approximately 5.00 and should stabilize within no more than FOUR (4) minutes.
d) Does the screen advance to step #5 "Calibration complete, press the [CONFIRM] key to save" within
FOUR (4) minutes (Yes or No)?
Yes Calibration completes! Press 'CONFIRM' twice to save the calibration. Problem solved for
now HOWEVER, if a false Blood Leak alarm reoccurs in the near future swap the listed
components (see Component List below) one at a time with known good and repeat
procedure number
No Turn the machine off and swap the following components (see Component List below), one at
time, with known good, and in between attempting the Blood Leak calibration until it calibrates
normally.
Component List: 1) Blood Leak Sensor #8
Board cable; 5) Functional Board
