Exchange the blood leak detector if one of these three values is out of limits.
1. Connect both dialyser couplings to the rinsing bridge.
2. Select menu 1.18 in TSM to perform a function check of the blood leak
detector.
3. Rinse the blood leak detector BL for approx. 1 min at the beginning of the
rinsing time with outlet flow pump FPA (approx. 1400 rpm). Thereby
possible air bubbles in the system are removed.
4. Rinse blood leak detector for approx. 15 to 30 min with FPA, approx. 1000
rpm to warm up the complete system to a temperature of approx. 40
o
C.
5. The LED Test is activated with the LED TEST OFF key. The OFF key switches

red LED must be as follows (the supervisor value is uncritical):
red LED Actual Status Controller
Blood Concentration
< 4.00
6. Press the LED TEST RED key to switch to the green LED. The RED key
switches to the GREEN key.
The green LED is tested. The controller value for the switched off green LED
must be as follows (the supervisor value is uncritical):
green LED Actual Status Controller

> 2.06
7. The actual controller values for the red LED and the green LED must be
divided.
Note: The calculated value of red LED divided by green LED is displayed
briefly after the key LAMP TEST is switched back to OFF.
The calculated value must be in the following limits (to the first decimal
digit/round off):
red LED / green LED
