Description
CPU1 interprets the air detector signal in a different way than does
CPU2.
– Acknowledgements (LDA1, X351/14) → X632/C13 and X633L/C10
recognize different signal levels.
The air detector alarm is not recognized by CPU2.
– Acknowledgement (LDA1, X351/14) → X632/C13, 0 V are missing.
– Transmission weakening (LDSA, X632/C16) → X351/10, 12 V are
missing.
Air detector clamps acknowledgement (CPU2) activated (clamp
closed).
– Acknowledgement (LDA2, X351/6) → X632/C14, 24 V are missing.
– Clamp control (CLP_CTL, X634L/C14) → X351/8, 12 V are missing.
– Clamp control (CLP_CTL, X632/C10) → X351/8, 12 V are missing.
Air detector clamps acknowledgement (CPU1) activated (clamp
closed).
– Acknowledgement (LDA2, X351/6) → X633L/C13, 24 V are miss-
ing.
– Clamp control (CLP_CTL, X634L/C14) → X351/8, 12 V are missing.
– Clamp control (CLP_CTL, X632/C10) → X351/8, 12 V are missing.
The blood alarm signal has not been cleared (indicates an alarm).
– Acknowledgement (BL_AL, X634L/C15) → X632/C21, 12 V are
missing.
If the HDF option is used, this signal is not tested (special function).
Closing of the air detector clamp via the CPU2 control line was not
possible.
– Clamp control (CLP_CTL, X632/C10) → X351/8, 0 V are missing.
– Acknowledgement (LDA2, X351/6) → X632/C14, 0 V are missing.
Opening of the air detector clamp via the CPU2 control line was not
possible.
– Clamp control (CLP_CTL, X632/C10) → X351/8, 12 V are missing.
– Acknowledgement (LDA2, X351/6) → X632/C14, 24 V are missing.
Closing of the air detector clamp via the CPU1 control line was not
possible, or CPU2 acknowledgement is incorrect.
– Clamp control (CLP_CTL, X634L/C14) → X351/8, 0 V are missing.
– Acknowledgement (LDA2, X351/6) → X632/C14, 0 V are missing.
