I have an 3.1 Ne X with PAB, Touch and Dosing that I bought 3 years ago. Firmware (5.14) is old because of problems with updating (error 8).

I have tried now for several days to get the dosingpumps working but without success. The dosing pumps are connected to the mains in the wall and the other cable to the S5-S8 outlet of the back of the Profilux. While trying programming the timers and sockets the PAB cable is disconnected. Can someone, please, tell me what I am doing wrong? Everything else is working.
