Hi, will a Wema S5 gevers (2 wire, blue/brown 0-10V) work on a GX Tank 140? If I connected to channel 1 (Vout and In) nothing happens. If i connected it to Vout and grnd, and move the swimmer up and down then the voltage changes between 0 and 10V.
If this doesnt work on the GX Tank140, which type/kind do i need?
thx
