Has any one any experience with installing and operating a Electromen EM - 285 DC Motor speed regulator (12/24v 20A). which are made in Finland.
Having read through the leaflet that came with the unit, and wired it up. I find that there are three potentiometer’s located on the circuit board. That need to have adjustments made to them. For anyone who is very knowledgeable on electronic, the terminology that is used in the leaflet would be very understandable. But someone like me who is very much an amateur hobbies, leaves me a little baffled.
I did email the companies support team, who did reply, but again basically repeating what was printed on the leaflet, that was from there head office in Finland.
The following was copied from the wiring, and installation sheet.
1. A range trim, to scale the usable speed range. (This is all that it says on the leaflet, it does not tell you how to go about doing this)
2. Current limit (l-lim ) limits the motor current, in other words the motor torque. This adjustment should be used to set the limit to suitable level according to the application?. (again it does not tell how to) I contacted there UK office, in there reply it stated that there are no specific guidelines on setting the current limit - they suggest experimenting, until you find something that suits the application in question. “Suits the application in question”, which is a little vague, so it seems its a case of hit and miss there.
3. Load compensation (RxI ) should be set to minimum in the beginning. Next set the motor rpm 20-30 %, and slowly increase compensation and simultaneously try loading the motor. If motor rpm is not affected by the loading the compensation adjustment is in optimum. But if motor starts to twitch or running turns nervous, the adjustment is overcompensating. (This has a lot more information on how to accomplish this, it seems that you make the adjustment on the compensation potentiometer, when the motor is running, and then make the motor have to do some work, and the reaction from the motor, dictates the adjustment’s that need to be made). Thats if I am correct in my understanding of what I am reading?
So if anyone with experience of having to make adjustment’s, like the one’s I have to make, can give me the benefit of there experience, on how they went about it, and put it in more understandable term’s for someone with a basic knowledge of electronic’s I would be very grateful.
