Anyone have any experience setting up contact closures?

I am using an Agilent 1100 as a pump for the reference spray on my UPLC/LCT Premier XE. I am also using an Alliance 2695 as a pump for the reference spray on a second UPLC/LCT Premier XE.

I want a process so that I can incorporate the external pumps into a shutdown method for the UPLC/LCT.
