Analytical Station Status/Recovery
Analytical Station Status Probable Cause
Run stopped. Right lift or sensor defective.
If this error occurs it will
not halt the action in
process, but it will prevent
initiation of a new sample,
unless the error condition
is corrected.
Stopped - inoperable. Red and/or white aperture
voltages outside range (135 to
175 Vdc for RBC aperture
voltage and 100 to 150 Vdc for
WBC aperture voltage). This
could indicate:
r The baths are out of diluent.
r A preamp cable is loose.
r The aperture voltages need
to be recalibrated.
Stopped - inoperable. Analytical
Station-to-Workstation
transmission failure. This could
indicate:
r The Workstation is OFF.
r The cables connecting the
Analyzer and the
Workstation are loose or
disconnected.
r A hardware or software
malfunction.
Stopped - inoperable. r Short on +48 V output
r Bulk Power Supply
If this error occurs it will
not halt the action in overheated
process, but it will prevent

TROUBLESHOOTING
ANALYTICAL STATION MESSAGES
Corrective Action
1. Ensure the right lift is unobstructed.
2. Reposition the cassette.
3. Reset the Analytical Station.
4. If the message persists, call your Beckman Coulter
Representative. You can place the cassette on the
rocker bed and press START/CONT to continue
running in the Automatic mode, or you can use the
Manual mode.
1. Open the Analyzer cover and ensure the six white
preamp cables are properly connected to the two
RED/WHITE PRE-AMP cards.
2. Close the Analyzer cover.
3. Reset the Analytical Station. While the Analytical
Station resets, ensure the WBC and RBC baths
drain and rinse correctly.
4. Continue operation. If the message persists, call
your Beckman Coulter Representative and indicate
the RBC and WBC aperture voltages need to be
recalibrated.
1. Ensure the Workstation is on. If not, turn on the
Workstation, log onto the Workstation and go to
step 4.
2. Ensure the cables between the Analyzer and the
Workstation are connected. If not, connect the
cables and go to step 4.
3. If the Workstation is turned on, shutdown and
restart it, then go to step 4.
4. Reset the Analytical Station.
5. Continue normal operation. If message persists,
call your Beckman Coulter Representative.
1. Turn the Power Supply MAIN POWER switch OFF
for 5 minutes.
2. Verify air filter is clean.
3. Turn the Power Supply MAIN POWER switch ON.
4. If message persists, call your Beckman Coulter
Representative.
