AIR DETECTED
EARLY
AIR DETECTED IN
BLOOD LINE
AIR IN AC LINE
BLAD air signal
indicates air before
220 ml plus plasma
return volume has
been pumped from
bowl.
BLAD air signal
indicates air when
fluid is expected, 25
ml after Draw began.
ACAD air signal
indicates air when
fluid is expected.
1. Use air detector test in Diagnostics to confirm the
problem.
2. Check, repair, or replace all electrical connections
associated with the BLAD air detector.
3. With fluid-filled tubing installed in the air detector,
measure the (+5 VDC fluid, 0 VDC air) BLAD signal at
P502 pin 31 on the backplane card. If no signal, replace
BLAD air detector.
4. Replace processor card. Using Utilities, calibrate all the
components under A/D, centrifuge, safety system, and
configure the language. Reset protocol parameters
(MODIFY key), if parameters were different from
default values.

3. If fluid is present in tubing and tubing is installed in the
air detector, measure the (+5 VDC fluid, 0 VDC air)
ACAD signal at P502 pin 29 on the backplane card. If
no signal, replace ACAD air detector.
4. Replace processor card. Using Utilities, calibrate all the
