F95 Bloodleak
Description
Blood leak channel and dimness not in alarm-free condition during the
T1 test.
– Dimness channel contaminated (calcium precipitate, etc.)
– Acknowledgement (BLL, X637A/18) → X633L/B10 voltage value
within the alarm tolerances (< 3V).
– Acknowledgement (BLL_DIM, X637A/21) → X633L/B11 voltage
value within the alarm tolerances (<1.5V/ >8V).
– 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, X637A/18) → X633L/B10 voltage value
not within the alarm tolerances.
– Acknowledgement (BLL_DIM, X637A/21 → X633L/B11 voltage val-
ue not within the alarm tolerances (<1.5V)
– Test detuning (BLL_DET, X632/A25) → X633L/B27 not 5V
– 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, X637A/18) → X633L/B10 voltage value
within the alarm tolerances
– Test detuning (BLL_DET, X632/A25) → X633L/B27 not 0V.
– Acknowledgement (BLL_DIM, X637A/21) → X633L/B11 voltage
value within the alarm tolerances (<1.5V / >8V).
– DAC_BLL or DAC_DIM not within the tolerances (check calibration)
System error.
