ADVIA 120 HYDRAULIC TROUBLESHOOTING GUIDE

The following is a troubleshooting chart that attempts to guide Field Service through some common hydraulic problems on the ADVIA 120. This is a REVISED version which contains extensive changes to page 14 concerning troubleshooting probe clogs and conductivity problems. Important Tips: When using this chart, the obvious has been eliminated. It assumes that on board Hydraulic Functions like System Wash and Flowcell Washes have been performed. Remember to return devices and tubing to their original positions before proceeding to the next procedure. If using the exerciser and opening Valves, do a Valve Check to close all valves.

PATHWAY TESTED

Rate flags in RBC/Baso/Reti c Channels

1.UFC Vacuum Test

STEPS

1. 2. 3. 4.

No Results

Go to Exerciser. Access the Pneumatics Screen and verify UFC and Main Vacuum readings. Open V5, V7, V10, and V13, Return to Pneumatics Screen and monitor UFC and Main Vacuum.

TYPICAL TIME

RESULT

CORRECTIVE ACTION [If Pathway Tested Fails]

Monitor for at least 1 min.

UFC Vacuum should not differ from Main vacuum by more than 5 in Hg.

Go to Exerciser. Dispense RBC reagent into reaction chamber by putting Shear Valve in Dispense Position and actuating V80. Open V21, V9. Open V20 and measure time to empty the chamber. Go to Exerciser. Dispense RBC reagent into reaction chamber by putting Shear Valve in Dispense position and actuate V80. Disconnect RBC flowcell sample line at top of sample syringe Disconnect RBC flowcell shuttle line at the bottom of flowcell and reconnect to nipple at the top of the sample syringe. Open V21 and V9. Open V20 and measure time to empty the
