Closing of the air detector clamp via the CPU1 control line was not
possible, or CPU1 acknowledgement is incorrect.
– Clamp control (CLP_CTL, X634L/C14) → X351/8, 0 V are missing.
– Acknowledgement (LDA2, X351/6) → X633L/C13, 0 V are missing.
The blood alarm message is missing.
– Acknowledgement (BL_AL, X634R/C15) → X632/C21, 0 V are
missing.
If the HDF option is used, this signal is not tested (special function).
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 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).
Raise level key on the air detector is constantly active.
– Acknowledgement (LEVEL_UP, X351/3) → X632/C11 not 0V.
Acknowledgement of the supply voltage for the ultrasonic output stage
not between 6.5 and 13.5 V after 3 seconds.
– Adapter board AD28 not connected
– Acknowledgement (X351/11 → X633L/25A jumper to X633L/B7)
not 12V.
– Relay on AD28 failed to drop.
Acknowledgement of the supply voltage for the ultrasound output stage
not >14.5V after 3 seconds.
– Adapter board AD28 not connected.
– Acknowledgement (X351/11 → X633L/25A jumper to X633L/B7)
not 16V/24V.
– Relay on AD28 is not controlled.
– No 10-Hz signal at ALARM_REST (X351/12)
