Greetings I have a Kone Econospace KCM831 with V3f25 drive that we are currently troubleshooting and getting no where with.
The problem: Upon powering back up unit immediatly get an fault 26-which is drive fault and elevator will not run in either direction. Elevator is sitting at top landing with doors open and doors do not cycle nor nudge. all fuses checked ok for door curcuit.
Secondly: we can turn the car on INSP via controller and hit run enable and down it sounds like brake is picking but car does'nt even attempt to move. we also have fault 21-Safety .No brk leds for ch1 or ch2 lighting up at all

Its gonna be a bad drive. Brake picks,no go. Just replaced one. $5000. Luckily we lost a 20 amp and convinced the customer to upgrade to a 25 amp. They split the cost with us.

Yes, cartop battery is a major issue. If you have a Batteries Plus in your area. Go there and give them your company name and you basically get batteries at almost half price. Wear your work shirt on the weekend and they will give you the discount...we replace them every 2 years. Brakes and encoders are a major issue on the MRL units.

Aquadog, Would love the PDF documents you have for the KCM831 with the V3f25 drive. We have a unit here with a bad drive, no manuals, troubleshooting flow charts and pretty much contractors abandoned the job. we have the fault log and that's it. any info would be greatly appreciated.

can I get the pdfs on this?

Me too

Is there anyone out there that can send me a fault code list for these elevators? I have 5 on service and the last company took all the info and electrical schematics for these units when they lost the contract. My email is [email protected]. thanks in advance.

Look at menu 4:10-11-12-13-14. record the values on the display and post them to insure you get the right documents for the software and CPU you have.
