New raymarine auto pilot and rudder reference

I just bought a new raymarine auto pilot and rudder reference to replace my old one. I need some help on where things go.

The P70 control head goes where the old control head was located.

The rudder position sensor is mounted next to the rudder.

Of course the wheel drive is mounted on the wheel where the old one was mounted.

Where does the:
EV sensor core and the ACU-100 go?

I expect not up next to the control head. Can they go below deck, or in a locker.

It looks like the ACU-100 needs to be mounted vertically. Do they need to be observed? There seems that there is only a light on them to show they are on.

I understand the cable scheme but not where they should be mounted.

May I have your experience.

Re: New raymarine auto pilot and rudder reference

the ev sensor is the compass. there should be instructions?... don't mount near metal. ideally it would be boat centerline at waterline.

the 100 would be anywhere conveinent. somewhere between the incomming power source from battery / DC panel and the pump. to keep total wire length short as possible.

I just got the ACU400.

Sensor core can go anywhere (doesn't have to be on center line) but does need to be at least 1m away from anything ferro or magnetic. There is a Android app from Gemeco called iNstall - which will measure the magentic fields on your boat for you.

ACU should be in a nice dry place - doesn't need to be monitored.

Re: New raymarine auto pilot and rudder reference

On my personal boat the Nav station is located in front of the 1/4 berth. The cockpit deck instruments are located on the bulkhead on the same side.

For simplicity I mounted the Ray autopilot “brains” and the Vesper AIS in the 1/4 berth onboard along the panel that backs to the cockpit.

This location lets me check all the LED lights in one spot when things don’t seem to be working. Or let’s me confirm at an glance that all is well with the inputs and outputs of the system.

Re: New raymarine auto pilot and rudder reference

You may not need the reference unit, certainly our yacht doesn't. Try without first to see.

The EV sensor goes somewhere away from metal objects, ours is in the cockpit locker mounted under the seat over a metre from the nearest wires. The unit can be turned in its frame to point in the right direction, there is an arrow on it so show which way

The ACU was also mounted in the cockpit locker but it can go anywhere away from heat etc.

Read the instructions carefully and use all the connection plugs even the blanks so you don't have any empty sockets on the NG network.

Re: New raymarine auto pilot and rudder reference

I just bought one not yet installed. The only thing you need in the cockpit is the control head and of course the wheel drive. The sensor must be located somewhere in the boat as far as possible from electric gear and the engine to get good magnetic flux for the fluxgate readings.

Doesn't your manual tell you this?
