Atk help

[01xp]

So I just got a atk hooked the aqua bus cable to the eb32 and apex ( tried both) the optical sensors are hooked up reading open or closed depending on how I screw with the sump level. Light on fmm is blinking green and pmup will not turn on. If I hook it into a 1link it will not turn off. Help I'm confused. O and I can't find it in the task bar of fusion
Thanks a whole bunch

Flashing green indicates your FMM module is powered with the power supply, but not communicating or connected to your Apex. Carefully inspect the AquaBus ports and each end of the AquaBus cable for any corrosion. Any corrosion, even on an unused AquaBus port anywhere on your Apex setup can wreak havoc on module communications.

See my ATK Tutorial for details about how to set it up, how the programming works, and a list of troubleshooting steps: https://www.reef2reef.com/ams/neptu...torials-part-3-automatic-top-off-kit-atk.692/
