TRAY MOVEMENT DETECT,
RE-ALIGN TRAY
This message indicates that the tray is out of alignment. This can occur if the tray is bumped
out of position. If this message appears again after the tray has been realigned, a horizontal
out sensor fault is indicated.
Troubleshooting
• Gradually move the tray forward or backward until the TRAY ALIGNED, PRESS RUN
TO CONTINUE message is displayed.
• Verify that the row of syringes is properly aligned with the current row of syringe holding
grippers.
• Push the RUN key.
• If the rack was bumped while it was in the rack loading position, pull the rack fully to the
front stop and press RUN. If the problem is not resolved, a horizontal out sensor fault is
indicated. Turn off the BD PrepMate™ Automated Accessory for a few seconds and
then back on to recycle the start position.
• If problems persist, call Becton, Dickinson and Company Technical Support.
WRONG DRAW VOLUME,
PRESS RUN TO RETRY
The mechanical draw action of the syringes is verified on each draw. This message is
displayed if the draw action is insufficient, most likely caused by a clog.
The last step of the BD PrepMate™ operating instructions is a visual verification of the
draw volume. The absence of this error indicates only that the mechanical draw action is
correct. The visual verification step must still be performed.
Troubleshooting
• To reset the fault: the operator is prompted to re-try by pressing RUN. The draw can be
tried as many times as desired. The mixing cycle will not be repeated if the draw cycle is
repeated.
• Run the draw cycle for the current row several times to see if the clog can be cleared. If
unable to clear the fault, press RUN and when the syringe plunger reaches the bottom
of its stroke, press STOP. This should allow the vial hold-down door to be raised so that
the syringes can be removed for inspection. Only do one syringe at a time. Be careful
not to bump the rack to cause a misalignment of the rack to the syringe position. Use
good laboratory techniques while performing this operation.
• Visually inspect the removed syringe to determine if a clog can be seen.
• Is the pipette orifice restricted in any way?
• Is there debris in the specimen clogging the pipette tips?
• Replace the syringe if clogged; move to the next syringe and repeat procedure. Once all
syringes in the row have been checked, close the vial, hold down door and press RUN.
• Are pipette tips resting on the bottom of the vial due to incorrect vertical stopping
position?
• If problems persist, call Becton, Dickinson and Company Technical Support.
