1. Use air detector test in Diagnostics to confirm problem.
2. Check, repair, or replace all electrical connections
associated with the DLAD1 air detector.
3. If fluid is present in tubing and tubing is installed in the
air detector, measure the (+5 VDC fluid, 0 VDC air)
DLAD1 signal at P503 pin 2 on the backplane card. If no
signal, replace DLAD1 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.
