DPM pressure
measurement exceeds
acceptable limit in
Ready mode (>100
mmHg).
Computer executed
an illegal instruction.
Computer is lost and
cannot execute
commands.
DPM pressure
measurement exceeds
acceptable limit
(<-40).
An internal
computational error
has occurred.
BLAD air signal
indicates fluid, after
bowl volume plus
plasma return volume
has been pumped
from bowl.
1. Check calibration of DPM in Diagnostics.
1. Check +5 volt supply.
2. 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.
1. This is a highly unusual message which may indicate an
intermittently defective DPM or A/D circuit. Check
calibration of DPM in Utilities.
2. Replace DPM and calibrate A/D and safety system in
Utilities.
3. Replace the 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.
1. Check +5 VDC power supply voltage.
2. Replace the 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.
1. If fluid still exists in the tubing and especially the bowl,
check for obstructions in the blood pump tubing or
effluent line, or for air in wrong bag. If no obstructions
exist, check the efficiency of the blood pump. Replace
blood pump rotor if efficiency is less than acceptable
value.
2. If no fluid exists in the tubing, the air detector did not
sense air. Replace the air detector.
