agilent 1100 series autosampler sample transport problems.
Posted: Thu Aug 25, 2011 8:55 pm
I was wondering if anyone out there has any experience with the sample transport on the 1313A autosampler.
I have a few things I need a little help with....all inter-related I think..
firstly... how the belt that drives the location on the motor arm above the gripper should be routed around the three guides that are present.
its a difficult fix but the belt can be replaced, we have one of these which had worm out its the belt,
so rather than just replace the whole sample transport unit ( very expensive ) we have located an aftermarket drive belt for a few pounds. but on taking the cover off the motor arm ( which requires removal of the Sample transport module) it isnt clear how the belt was previously routed around the black guide pillars,
most attempts so far have resulted in jittery gripper arm movement during initialisation, and a crashing of the gripper arm into the needle compartment perspex.
There may be a tension issue causing the jittery movement, but until I am sure how the belt should be positioned, its hard to know.
any advice would be greatly appreciated.!
I am also not sure whether the motors need to be aligned in any particular way when attaching the belt, which may be why the gripper is crashing into the sample compartment?
lastly.... I have read somewhere about using the torque2 macro to read the feedback from the motors, any information on how to do this would be useful... given that the module never Initialises fully, faulting out with motor 2 over temperature when the gripper arm has collided with the sample persepex. it makes a fast clicking sound then if you leave it on causes the motor overtemp fault.
cheers!
