There is a big jump from Marklin throttle to Rokuhan RC02. first of all it has a automatic circuit breaker and it will trip at less than 1 amp load while the Marklin unit will supply enough to burn things and weld things on occasion I also have no problems with most of my Marklin stuff but I know from experience if they are stiff from sitting on the shelf, the breaker in the RC02 will trip. regards Garth Great post, Garth. I am actually working with a customer who returned an RC-02 to me and when I re-tested, it works fine. Found out he is using Marklin loks, but he says they run fine on another layout. In the midst of troubleshooting at the moment and this was one of my suggestions ... possibly gunked up trucks/bogeys, but the timing of your post is uncanny. Thank you for supporting my suggestion of checking into the locomotives. One more thing... do you think the RC-03 would have less of an issue since the pulse magnitude/duration is slightly larger/different shape? I don't have the traces handy, but when I o-scoped these two units several months ago, there is quite a delta between the signals coming out of the two. Is there an eventual plan to phase out the RC-02 (new model could be RC-04?) with a similar circuit as the -03 ... like the transition from -01 to -03? Thanks.

Frank the RC003 is designed for large layout use and so has a higher current rating, and latest electronic circuitry, bu t it is still just under the 1 amp rating. Marklin engines have always had a wide range of current draw even among copies of the same model. The RC002 is designed for smaller layouts plug and play wiring and the use of Rokuhan equipment so in that environment it works fine, and is the correct choice for the job.
As to a new controller/throttle, what we see next will probably be a DC box with blue tooth connectivity so you can run trains with an android with an ap, But I would not expect it to have a higher current rating than we see currently. I would not be surprised if Rokuhan even comes out with their own version of a DCC throttle, but with max 12v ac to track and current rating in 1 amp range.

I was able to find issue with my customer's RC-02. It ran 6 MTL GP9/SD40's just fine. One Micro-Trains SD40, though, led to the RC-02 shutting off when the lok hit an R195mm curve. I changed power supplies ... ran the same engine on my Marklin 67271 without issue for about 20 minutes. I checked the motor temperature and the SD40's maxon motor was not heating up. It was lukewarm to the touch. I then lubricated this locomotive with Conductalube with focus on the copper pickup that connects the "ball" on the truck to the chassis. I re-ran it with the RC-02 and went two hours without issue, even at higher throttle on the RC-02. This is odd. I wonder if this RC-02 is indeed defective? I wonder if the shutoff current is too low for RC-02's? However, this proves that the locomotive conductivity is one effect on the RC-02 power supply shutting off.

I also have no problems with most of my Marklin stuff but I know from experience if they are stiff from sitting on the shelf, the breaker in the RC02 will trip. I actually use the Rokuhan's circuit breaker to let me know when it is time to clean and lube my Marklin gear. If it pops the breaker, it's time for a little maintenance work! (Ahh yes, 1972 technology: slot car motors on 6.5mm rails - we have made progress since then!)

Frank, Since you fixed the sd-40, we can't play with that. If you want to check out the current trip, get yourself a couple of power resistors and connect them across the throttle. Seems to me a 15ohm resistor would check the throttle at about full power.

Not to hi jack but I have a question about the RC-02 for you electronics guys. On my RC-01 I have a set of panel mount gauges to read the voltage and amperage to my test track Gauges are simple analog 2 wire gauges, "V" in parallel, "A" in series, With a DPDT on/off/on switch to reverse direction.
Is it possible to wire up the gauges to get separate readings for constant lighting and the train throttle on the RC-02? What I'm trying to do is setup a 2nd smaller more compact controller to use on my work bench.

The quick answer is no. The constant lighting on the RC-02 is a mechanical detent on throttle to set the zero throttle point at a value >0 and <motor starting throttle.

There is a big jump from Marklin throttle to Rokuhan RC02. first of all it has a automatic circuit breaker and it will trip at less than 1 amp load while the Marklin unit will supply enough to burn things and weld things on occasion, secondly it has constant lighting circuit. I use them all the time at shows on wall transformer power and the trip does not come quite as quickly as it does on battery power, with batteries installed, as soon as plug in your wall transformer the batteries are eliminated from the power grid. I can comfortably operate 2 MTL Geeps provided they do not have DCC on board, or 1 F unit from MTL that is of recent vintage and well run in. AZL I have no problem with GP38-2 and RDC I have run SD70/75's but do not have any in my stable at present. I also have no problems with most of my Marklin stuff but I know from experience if they are stiff from sitting on the shelf, the breaker in the RC02 will trip. For me best test is to use a pice of 220mm straight track using Rokuhan Track connector A008 between track and controller and then use the AZL RDC or MTL GP35 and if they run there is nothing wrong with the controller. I have 3 RC 02 1 RC001 and ! RC003 cause my show layout has 5 loops. regards Garth on full power it ran a couple of inches at approx. 2mph making a loud humming noise then the controller cutoff operated. samsung s5 hülle

Alfred, Welcome to the group. If you're looking for advise, you really need to provide a bit for information as to what you're running and how you're running it.

The quick answer is no. The constant lighting on the RC-02 is a mechanical detent on throttle to set the zero throttle point at a value >0 and <motor starting throttle. Mark constant lighting is not going to be read accurately with and AC or DC meter, it can be seen on an oscilloscope if you know how to set it up to read both the DC and the CL voltages on the track at one time. as for the adjustments the Constant lighting is on constantly the mechanical stop is to allow you to set the DC throttle down to the point where the engine does not move on the track so the constant lighting is not affecting its operation and then when you advance the throttle the engine starts to move and will accelerate away from the stopped position.this position could be different for every engine in your fleet or you will find similar engines have the same set point. So I do not find meters to be the answer to setting the stop point as it is not zero volts for constant lighting at that point it is a combination of CL and DC at which there is not enough DC for the DC added to the CL to start your motor turning, regards Garth

Just got my first track up and running with an RC-02 controller. Shorty works perfectly but AZL SD-45 just gets lights on and will not move. Help!

I would contact the dealer but this is usually the fix:

Thank you for your prompt reply Followed the directions on the video. They have upgraded their design on the SD45 as it has 2 prongs to hold it in place. Still no joy. I have 8 AZL locomotives and this was my first shot at trying them. So I tried a Coaster engine and it worked fine. I tried my other SD45 and it worked as well. I will test the rest of my engines and confirm that they work and contact AZL on my defective engine.

Hi All, I posted this on the TrainBoard as well.
I finally set up a test track and hooked up the Rohukan RC-02 with an adapter to an MTL starter oval, to test some locomotives. The power light comes on, but nothing happens. The locomotive does not run. I then put a nine volt battery on the locomotive wheels, and it runs. Touched the battery to the tracks, and the loco runs. I took the controller to work where my co-worker tested it on a oscilloscope, the power came on, the forward/reverse switch worked, but the speed dial did not work. No change in the wave. I contacted the vendor, so I'll wait and see what he says.

Scott hello! Sorry for the issue. Question, are you using batteries or the A028 wall adapter? If you are trying with batteries, you may want to try with the A028. Either way, if you purchased through one of our authorized Rokuhan dealers, then you are covered under warranty. We are the North American distributor for Rokuhan and cover all products purchased through our channels. You can also contact us offline. - Rob
