Re: [Amel Yacht Owners] Bow-Truster overheat

Hello Reudi;
 
Yes, the Amel 54 has a thermal cutoff to prevent damage to the thruster as well as continuous high current draw (Around 550 Amps at 24V) which could lead to fire on board. We've had the thermal cutoff kick in  only a couple of times and it has reset in a matter of minutes. We have not timed the exact reset duration.
 
I'm not aware of any adjustments in the thermal cutoff. The bow thruster has a direct connection to the batteries without a breaker. The thermal cutoff is the only safety items preventing major damage to the thruster and/or wiring.
 
Try to use the thruster in bursts (less than 15 seconds), as much as possible, so it has time to cool down between usage. We try to over correct a bit when we use use the BT so as the bow falls off, the BT has more time to cool.

Subject: [Amel Yacht Owners] Bow-Truster overheat

 

Dear Forum

On my Amel-54 I discovered that the bow truster stops working after repeatingly use within 10-15 min timeframe.

I used the bow truster a bit more than usual when I practiced some manouvers first time; - and on a second occation when I had to manouver in a marina with a lot of windguests of 18+ kn and another chain over my Anker.

It stopped working and after a while (maybe 10 min.) it re-started & operated normaly. I know BT Is not made for constant use, - only few seconds at a time. Then wait and re-use another time.

Question from a beginner:

Does the bow truster has a termic fuse which is activated after some time of usage to save the motor from overheating? 

Does anyone know exactly how it works and if this can be adjusted because I think the BT on Wasabi switches of quite fast. Any ideas or other information?

Best regards
