Binary Pump 1290 "Valve Overcurrent" error

Hello everyone, We have a Binary UHPL 1290 Infinity I that shows an error when we selec Chabnel A1 with any channel B (B1 or B2) it shows a "Valve Overcurrent" error and the pumps stop the flow and shows the error red light. This does not happen with the channel A2 with anny channel B. Witch is the cause of this error? Is posible to fix it without change parts?

  • Hello Hermes,

    Since you can use the A pump with any B channel and can also use A2 with A channel, I think the error may be pointing to the Solvent Selection valve [SSV] issue specifically when trying to open the solenoid for A1 channel.  Afraid that would require changing the SSV.
