Sample Loader
Sample Loader Faults - Resume Loader
Some Sample Loader-only faults do not require the Sample Loader to be re-
initialized. In these cases, when the operator presses the
[CLEAR FAULT]
key
followed by
[START LOADER]
, a submenu is displayed showing both the
[RESUME
LOADER]
and
[RESET LOADER]
keys as well as
[RETURN]
. The operator has the
option of using either RESUME or RESET to activate the Sample Loader. Refer to
Restarting the Loader
for a discussion of when to use the
RESUME
key versus the
RESET
key.
Processing Stations
There are three processing stations on the Sample Loader. These stations are
described below and shown in Figure 13.7. Mixing Station 1 corresponds to the
first tube gripper in the Mixing Block and Mixing Station 2 corresponds to the
second tube gripper.
Station 1, First Mixing:
A sensor detects the presence of a tube and activates
the mixer. The sample is mixed in a 135° rotation for
approximately 40 seconds.
Station 2, Second Mixing: A second sensor detects the presence of a tube and
activates the mixer. The sample is again mixed in a
135° rotation for approximately 40 seconds.
NOTE:
Several Sample Loader-related error messages refer to tube positions 3
and 4, which are Mixing Stations 1 and 2 respectively.
(Refer to Figure 13.7.)
Station 3, Vent/Aspiration: The tube is positioned for aspiration. The bar code is
read. The spinner mechanism descends, detects the
tube height, grips and spins the tube, allowing the Bar
Code Reader to read the label. The tube stopper is
punctured by the Vent/Aspiration Needle (the
“Needle”) in the Tower Module. The tube is vented
and the sample is aspirated.
These three stations are adjacent to each other. Each sample is mixed twice before
being vented and aspirated.
