Sample Loader Faults - Resume Loader
Some Sample Loader-only faults do not require the Sample Loader to be re-

followed by [START LOADER], a submenu is displayed showing both the [RESUME

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.
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:
Station 2, Second Mixing: A second sensor detects the presence of a tube and

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
