System error
Description
During the start phase a negative pressure of more than 450 mmHg has
developed (max. test running time 120 seconds).
– The hydraulic system is contaminated,
– the air separation pump started running
Setting the dialysate pressure to the test pressure (–300 mmHg to –450 mmHg)
was not possible (max. test running time 120 seconds).
Upon repetition of measurement, the range was extended from
–260 mmHg to –490 mmHg.
– Leakage in the hydraulic system
– The UF pump is defective
The working point (116 digits) of the differential amplifier cannot be set correctly
(max. test running time 120 seconds).
– Pressure variations are too large
– The D-A converter (IC11) on P.C.B. LP 632 is defective
– The operational amplifier (IC1/IC3) on P.C.B. LP 632 is defective
– Acknowledgement (P_DIAL, X633L/B6) X632/A29 is defective
– CI signal is missing (P.C.B. LP 632 X632/B22).

Calibration fuite de sang
To calibrate blood leak detection on the Fresenius Medical Care 4008 S:
1. Access Calibration Menu: Use the arrow keys to select the "Flow setting" field.
2. Set Blood-Leak Voltage:
- Press the +/– keys to set the blood-leak voltage to 5.0 V.
- Confirm with the Audio paused key.
3. Set Dimness Voltage:
- Press the +/– keys to set the dimness voltage to 5.0 V.
- Confirm with the Audio paused key.
4. Wait for Confirmation:
- After approximately 3 seconds, the system will display "DATA STORED".
5. Verify Tolerances:
- Blood-leak voltage should be 5 V ± 0.2 V.
- Dimness voltage should be 5 V ± 0.3 V.
6. Check for Contamination:
- If values deviate, inspect the glass burette for contamination.
7. Ensure Proper Conditions:
- Close the housing.
- Maintain a temperature of 37°C.
- Avoid external incident light.
After calibration, ensure proper installation and positioning of the cuvette to maintain accurate readings.
