Liquiphant FTL33
Valve plug, cable
Depending on the assignment of the connector or the wiring of the cable, the device works in
either the MAX or MIN operating mode.
When the cable is wired, one wire of the cable does not have any function in each of the
operating modes (gray in the case of MAX, and brown in the case of MIN). The cable with no
function must be secured against inadvertent contact.
