Description
The temperature measuring range is not set to hemodialysis.
– Control line (HOTRINSE, X634R/C24) → X639/A20, 0 V are miss-
ing.
– Acknowledgement (HOTRINSE, X634R/C24) → X632/A26, 0 V are
missing.
The actual temperature is less than 35.0 °C (test running time > 15
minutes).
– Calibrate the temperature.
– The heater rod failed.
– Acknowledgement (T_DIAL1, X633L/B16) → X632/A24, voltage got
stuck.
The actual temperature is higher than 39.0 °C (test running time > 15
minutes).
– Calibrate the temperature.
– The regulating sensor (NTC-2) is defective.
– Acknowledgement (T_DIAL1, X633L/B16) → X632/A24, voltage got
stuck.
The temperature failed to stabilize within 15 minutes.
– Acknowledgement (T_DIAL1, X633L/B16) → X632/A24 is steadily
changing (change > 0.3 °C/15 sec).
Detuning in positive direction not higher than 3 °C (10 sec).
– Acknowledgement (T_DIAL1, X633L/B16) → X632/A24, change in
voltage insufficient.
– Detuning (T_DETADJ, X632/A23) → X633R/C21 insufficient.
The monitor sensor indicates a constant value.
– NTC-3 defective.
The test release is missing (max. test running time is 10 minutes).
– Run-time problem (software).
CPU1 failed to transmit a Bibag status message within 3 sec.
– Run-time problem (software).
Bibag NTC_BIB detuning not higher than 1 °C.
– Acknowledgement (NTC_BIB, X633R/C15) → ADW on P.C.B.
LP 633, change in voltage insufficient.
– Detuning (BIBAG_TE, X634R/A13) → X633R/A20 insufficient.
Bibag temperature display outside of measuring range (15 to 45 °C).
– Acknowledgement (NTC_BIB, X633R/C15) → ADW on P.C.B.
