Some advice please on setting up the 7651 crane. I know that it will not work with the Mobile system , as only the light function and magnet work. The manual states that it will only work through a Central Unit/ Central Control Unit with the Control 80f as the crane controller.

I will buy the old Central Units just to run the crane but need advice on how much of the old system is required.

The manual shows a transformer, a central unit and the 80f but the 80f appears only to be an add-on. I would prefer to buy a transformer and either a 6029 or a 6021,both of which seem to have the necessary function buttons without the need for the 6020 central unit. The transformer, central unit and 6029 are available on eBay . I am not sure how the components are connected, hopefully by the usual Marklin black/red/yellow/grey connectors at the back of the controls. I presume that the multi pin sockets on the side are only for connecting boosters, which I do not need

Grateful for your thoughts.

Many thanks for the swift and helpful reply. I do not know why it will not work with the mobile station, but the manual says that it will only work with a specific system. I have also emailed my supplier, Keesmarklin in the Netherlands for his view.

I will look at the link.

Oh yes, I would like to add, the mosfet driver for the crane magnet on the decoder is rather weak and sensitive, it already went up in smoke once here... But I was able to repair it by replacing the component, I still have a stash of replacement fets (that are now long obsolete and difficult to get). So be carefull with it! (dont energize the magnet for too long)

I don't own a stationary crane, but a first issue Goliath. Wanting a magnet, I ordered the one for the tower cranes. I connected the wires to a toggle switch and my 32va blue transformer.

Hi Glenn/All,

I upgraded my 7651 to overome the reverse bit which is missing from the original decoder. With computer control you need to rely on the decoder to know which direction has been set at all times.

Here is my upgrade article 7651 LP5 Upgrade

Many thanks to those of you , who offered advice on my difficulties with the crane operation. I sought advice from Marklin and their solution below works after some more lubrication and checking the seating of the brushes. It would not work on the earlier grey MS and I changed the address back to the factory setting of 30, as advised:

Dear Mr. Kelly,

the crane can be operated with any item producing a MM track signal. Please give your MS2 a try.

I think, address 80 is not the best choice as it is the last address. Please use the default address 30.

You only need F0, F1, F2 and the speed knob to control the crane. Please follow the advices in the manual.



Mit freundlichen Grüßen

I wonder why my posts disappeared. Here and in the Northlander discussion. What have I done wrong???

Last week. I wrote that the analog steering of the crane is the best way, because only then you are able to turn and lift at the same time.

I also commented on the TEE classic that a BR 218 or a Nohab would a good engine to pull the the coaches of the former Northlander.

Very strange to find out that both posts have disappeared.

The database has been restored to 2024-08-11 05:00 (Local Swedish time), so any posts made after that time will be lost.

It is what it is, we are fortunate the issues weren't any worse than what they were.

There is nothing stopping you from reposting your posts.
