Hi Chris,
We just had a PAL, TCEA and Gasbench installed, so I'm no expert.
However, I may have a solution for you, if I properly understand your
problem.
It is my understanding that Tray01 has to be the active tray in the
PAL job queue (at least when you plan on switching from one
peripheral to the other). So, you will need to rename the VT98 tray
and the GB tray as Tray01 each time you switch peripherals.
This means you need to have a properly configured (X,Y,Z coordinates,
etc.) tray to begin with.
Under Menu/F3/Setup/select the Objects menu.
Select Trays.
Select (or create) the VT98 tray and calibrate its coordinates in the
same fashion as you did for your Gasbench. Remember, it is a
different trayholder type (THldr1 I think) and type A.
When switching from the GB to the TC/EA, you will need to delete the
Tray01 job from the job queue.
Then, go back into Menu/F3/Setup/Objects/Trays. If a Tray01 exists,
I'd copy it and rename it for a backup. Then, delete Tray01.
Copy the GB tray or the VT98 tray and name it Tray01.
At that point, the Tray01 should appear in your job queue. Go in
and check that it is referring to the proper tray (GB or VT98), and
change your AS method to the appropriate one.
I think that is the correct order of events...

Hello all,
I am attempting to convert our CTC GC PAL autosampler to use with both a
TC/EA and Gasbench. My trouble is that I'd like to use 2 trays (1 with
the Gasbench, another with the TC/EA). All else is well in that I have
gone into configurator, etc. When running a sequence it communicates with
the PAL. Unfortunately, I cannot use the predefined trayholder (to use
with VT98) by redefining coordinates, as the position offset lies outside
the y range. I hope that makes sense.
Can anyone guide me as to script in say "Tray3" instead of
Tray01 or another way around this?
Much appreciated,
Chris
