We have old Nichiyu FBT-20PN 67BC and it shows the error "C33 contactor EPS". We have already changed the contactor EPS and capacitor in the controller EPS (both were burnt). Nevertheless the error keeps showing and the wheel doesnt turn. Does anyone have any ideas how to make it work without changing controller EPS?
Showing items 1 - 5 of 5 results.
Thanks for fast and full answer. We checked the wiring and found it working correctly, so we will try to find another MPU-board. Kind regards.
Hello Alex,
Ok, I think it would be better to controle the following;
- Of the MPU-board connector 1 pin 6 and 14 are the wiring of the coil of contactor EPS. check the wiring and see if you tension on it when the contact switch is on.
- Replace or repaire the MPU-board.
Kind regards

Marc, thanks so much for the manual and the list of errors. That manual really helped us to understand the problem, but after all the error still remains, though we dont see any broken parts. Dont you have any ideas what we can do else to solve our problem?
Marc, Please, could you send the manual to me too?
Thanks in advance.
Regards
Hello Alex,

Kind regards
