Gallus RCS 330 labelling machines contain six Berghof RDC1-EC-Pa servo motor controllers per colour bank which control pressure feed, impression feed, cross-adjustment and format setting. These controllers are notorious for having high failure rates and being expensive. In many cases a faulty power supply is the problem. However, we have repaired controllers with faulty optocouplers and FET drivers.
Electronic Innovations has traced out the circuitry of these controllers and repaired 45 units to date. Please call or send us an email if you would like your Berghof RDC1-EC-Pa controllers repaired.
