Raymarine S1 Compatibility

[olivioloyer]

Hi everyone

I have a S1 autopilot course computer E12180 with a MKII wheel drive and I would like to install Linear drive M81130 insted
Are they compatible?

Thanks a lot

Best Regards,

I have seen S1 units with and without a clutch outlet. If your S1 E12180 has it, you won't have a problem.
If you don't have it, you'll need to add a switch to activate it.

Just a few days ago I started this thread:

But it seems that no one has been interested...

Thank you Tehani,

Ok apparently it does have a clutch outlet, what I am concerned about is the possible power draw much higher on a linear drive than my current wheel actuator.

But from the docs it seems that it is the same controller, I just want to make sure I am not burning my controller before buying that expensive piece of hardware.

Thanks

See the table on page 5 of this manual:

S1 is compatible with linear unit type 1, but pay attention to the thickness of the cables.

Unfortunately the link to the document does not work, it says that the file has been removed.

But if it is just about thickness of cable, fine by me!I'll put a bigger cable!

Btw, I was asking that same question to raymarine support, and their answer was basically buy a new complete EV-200 pack!!! because your S1 does not have enough power...

Should I be sceptical about their answer?

It's on the Raymarine website: manuals -> product legacy -> Autopilots.
It can be seen that S1 is compatible with drive type 1.

Yes, completely. They always want you to spend more money.
On the other hand, these APs can be "tampered with" quite easily, because their Mosfets and PCBs are oversized. (Just cheat the CPU a bit...)

Thank you

Well unfortunately the linear drive that was for sale second hand for 700usd is not anymore...

But I hope I'll find another one closeby,

Btw how does it work if you need to disconnect the linear drive in an emergency, is there a safety feature, because it could potentially prevent you from steering the biat if it malfunctions

[Tehani]

Sure, I see you're not used to automatic clutch actuation. When STBY is activated on the keypad, the rudder is free.

And the normal thing is that if the clutch does not work, the AP simply cannot take control of the rudder even if the motor turns. I do not know of any case in electromechanical linear units with planetary, where the rudder is blocked for manual handling, but with the hydraulic ones I think it could happen that the bypass solenoid valve gets stuck.

[Frankly]

IIRC the S1 series APs were designed to drive the wheel pilots and small outboard hydraulic units. Rated current in these situations is about 6 amps with max current maybe up to 10 amps. Do not remember if the S1 series had circuit to monitor the motor current but the replacement X-5 did. When the peak current got up around 10 Amps you got a rudder stopped message. Depending on your steering forces/ motor current you may or may not trigger that condition.

This table is in the manual S1, S2, S3 SmartPilot Install & Commissioning with ST6001...

Hi again Tehani,

Seems that I won't get that linear drive anyway and a new one is too much money, plus installation is more complicated than I thought.
Do you think EV100 autopilot is compatible with my setup?
Do you now of any other compatible wheel pilots that might be stronger than the ST4000MKII?

Thanks again

EV100 is the "natural" replacement for the ST4000. And the complete kit with the wheel drive is not very expensive...

You will need more power depending on the length and displacement of your boat. The next step up from the wheeled ST4000 is the type 1 linear drive. Simrad has similar scaling.

Muchas Gracias Jose Luis,

Checare tambien lo de simrad.

Que tengas un buen dia
