Description
Blood leak channel and dimness not in alarm-free condition during the T1 test.
– Dimness channel contaminated (calcium precipitate, etc.)
– Acknowledgement (BLL, X637/A18)  X633L/B10 voltage value within the
alarm tolerances ( 3 V /  8 V)
– Acknowledgement (BLL_DIM, X637A/21)  X633L/B11 voltage value within
the alarm tolerances ( 1.5 V /  8 V)
– DAC_BLL or DAC_DIM not within the tolerances (check calibration)
The blood leak alarm / dimness alarm is not recognized during test detuning.
– Acknowledgement (BLL, X637/A18)  X633L/B10 voltage value not within
the alarm tolerances ( 3 V)
– Acknowledgement (BLL_DIM, X637A/21)  X633L/B11 voltage value not
within the alarm tolerances ( 1.5 V)
– Test detuning (BLL_DET, X632/A25)  X633L/B27 not 5 V
– Calibration of DAC_BLL or DAC_DIM is too high
– Detuning (DAC_DIM, X634R/A11)  X633L/C3 impossible
– Dimness calibration is set to potentiometer calibration
(BR6 from pos. 1/2 to 2/3)
After test detuning, the blood leak channel and dimness fail to enter the
alarm-free state.
– Dimness channel contaminated (calcium precipitate, etc.)
– Acknowledgement (BLL, X637/A18)  X633L/B10 voltage value within the
alarm tolerances (3 V /  8 V)
– Test detuning (BLL_DET, X632/A25)  X633L/B27 not 0 V
– Acknowledgement (BLL_DIM, X637A/21)  X633L/B11 voltage value within
the alarm tolerances ( 1.5 V /  8 V)
– DAC_BLL or DAC_DIM not within the tolerances (check calibration)
System error
Description
The temperature measuring range is not set to hemodialysis.
– Control line (HOTRINSE, X634R/C24)  X639/A20 not 0 V
– Acknowledgement (HOTRINSE, X634R/C24)  X632/A26 not 0 V
The actual temperature is less than 35.0 °C (test running time > 15 minutes).
– Calibrate the temperature
– The heater rod has failed
– Acknowledgement (T_DIAL1, X633L/B16)  X632/A24, voltage got stuck.
The actual temperature is higher than 39.0 °C (test running time 15> 15
minutes).
– Calibrate the temperature
– The regulating sensor (NTC-2) is defective
– Acknowledgement (T_DIAL1, X633L/B16)  X632/A24, voltage got stuck.
