Troubleshooting
• Has the latch been opened and closed?
• Has a specimen rack been removed and/or added to the tray?
• Does the latch rotate freely from open to close position with and without the rack in
place?
• Call Becton, Dickinson and Company Technical Support if the answer to each of these
questions is "yes" and problems persist.
To reset the fault: follow message on the display, verify that the latch is closed and
seated, and press the START or RUN button to continue processing
CLOSE VIAL HOLD-DOWN
DOOR, PRESS RUN
The vial hold-down door must be latched in the down position for the BD PrepMate™
Automated Accessory to run. Attached to this door are mechanical fingers that engage the
top of the specimen vial so that the vial cannot be raised out of the rack when the syringe tip
is removed from the vial.
The door can be rotated upward to access the syringe grippers/pipettes. There is a proximity
sensor that senses the position of the door and prevents the BD PrepMate™ Automated
Accessory from operating if the door is raised or unlatched. This message is displayed any
time the door is raised.
If a processing cycle is not in progress, another one cannot be started until the door is
closed. If a processing cycle is in progress, it will stop when the door is raised. To restart the
cycle close the door, and then press RUN.
Troubleshooting
• Is the vial hold-down door latched in place?
• Has the BD PrepMate™ Automated Accessory been moved?
• Check to see how the cover and hold-down door are mounted on the instrument.
• If problems persist, call Becton, Dickinson and Company Technical Support.
PIPETTE PLUNGER UP,
PRESS RUN
A through-beam fiber optic sensor is located in front of the vial hold-down door. It is
positioned to shine the beam directly over the top of the syringe plungers. If any of the four
plungers in the row is not completely down, just before the syringe enters the syringe
grippers, the sensor detects it and stops horizontal movement so that the syringe will not be
forced into the gripper. This message will be displayed and the plunger must be pushed
down before the run continues.
Troubleshooting
• Do the optic sensors line up with each other on the door?
• Is there a beam of light being emitted from one sensor to the other sensor?
• Are all plungers pushed down on the syringes?
• Has the specimen rack been re-seated into the tray?
• Are there any plastic pieces (flash) sticking up from the top of the plunger?
• If problems persist, call Becton, Dickinson and Company Technical Support.
To reset the fault: follow the message on the display and press the RUN button to
continue processing.
