Hello-

I have an HP 1050 HPLC that won't read my shutoff macro. When I turn the HPLC on to equilibrate the column, I have to enter it manually on the pump keypad. If I try to turn it on in the instrument setup software, I get an error that reads "previous command "PREPRUN, STANDBY, PUMPALL, or LAMPALL" still running in background" yet I can't find anywhere to turn this off??? And as I mentioned before it won't read my shutoff macro, so after the run is over it keeps running until I come in and manually turn it off (again on the keypad). Can anyone give me some helpful advice?

Thanks-
Beca
