Neither Lab Advisor, nor ChemStation can find the pump module

solyom Jan 28, 2019 12:30 PM

Hi,

I have two instruments (Agilent 1200RR and Agilent 1290) connected to one computer that runs OpenLab CDS, ChemStation Edition, Rev. C.01.07SR3 under Windows 10. Today, when I turned on the system, the ChemStation couldn't find the pump on the 1200RR HPLC. The Lab Advisor also couldn't detect the module. (All the other modules, autosampler, DAD and column heater are detected). I closed and restarted both the computer and the HPLC system (in the right sequence), but it didn't help. The pump is powered, the green light is on and I can hear the slight "humming" inside the module. I switched the LAN cables between the pump and another module, and the cable is fine, it worked with the other module.

I would appreciate any suggestion I can try to figure it out what is the problem. Thank you!

Aniko

Hello,

I added a some tags to make this post a little more visible. As this is looking to be more of a HPLC instrument hardware issue and not a software issue, I am moving this post to the Liquid Chromatography area of the Community.

What model number of this pump module?

  Hi,
  Thank you for your quick reply and moving the post to the LC area and tagging it as hardware issue! It is my first post, so I still have a lot
  to learn.... The pump is a binary SL pump, model number G1312B.
  Thank you!

    Hi,
    Is the indicator light (top right) solid or blinking?
    Do you have a hand held control module to try?
    Which DAD do you have?

      Hi,
      The indicator light is solid green, the model number of the DAD is G1315C (DAD SL). Unfortunately, I don't have hand held controller, everything is controlled through the computer. Thank you!

Hi Aniko,

Have you changed firmware to any module on that 1200 stack recently? Have you made any other changes, like switch a detector, or change the configuration in openlab?

  No, I haven't done anything like that. The firmware was updated last time approx. a year ago when we switched to Windows 10. I was running samples without any problem last week and turned off the system for the weekend. Monday morning when I turned on the system the pump was not detected.
  Thank you! Aniko

    Hi Aniko,
    
    In this case I would lean towards a bad mainboard on the pump. You could try doing a forced cold restart, which would involve turning the pump off, arranging the switches in the back to have 1,2,5, and 8 up and all the others down. Turn the pump back on and see if it can be found.

      Unfortunately, the forced cold restart didn't work.... Is there any way to test the main board before I order a new one? Thank you!
