Agilent 110 making clicking noises after replacing pistons.

Mr.DPHN

Hi all, 

My lab has a agilent 1100 with a binary pump (g1312A). After disassembling the pump head, replacing the pistons, and reassembling the pump head the pump unit will not start correctly. Upon being powered on the LED cycles through red, green, and yellow and the unite makes a few rapid clicking noises. Then the light stays a solid yellow and the pump does is shown on chemstation as "offline." Does anyone know what to do or had a similar situation?

Let me know if there are any more details I can provide.

    Hi

    For noise, may be piston and seal are not properly lubricated with mobile phase before installing.

    Check seal and piston again.

    If you have lab advisor software then do system pressure test and pump leak test to know that it's okay if passed.

    To my knowledge I do not have access to lab advisor software.

    You can download it if you want...

    Through diagnostic of chemstation, you can do test of pump..
