Evolution Autopilot ACU-400 LEDs

[vickihoward]

Hello Forum.
We just applied external 24 volt power to the autopilot ACU-400 for the first time. The EV-01 sensor has a green light. On the ACU-400 we see a red light at the ON side of the SeaTalk power switch in the ON position and we see a yellow light at the 24v side of the clutch 12v/24v selector switch in the 24 volt position. We have not tried to turn on the autopilot with the P-70 control unit. What do the red and yellow LED lights on the ACU-400 mean? We can't find the explanation of the ACU-400 LEDs in the installation manual.
