Marathon 16 Km Err 5
Our Marathon 16 KM is returning a Err 5 and stopping the run while it accelerates to the set speed. Occasionally if the speed is started low and manually accelerated during the run then it will operate with no problem. Currently however even that is no longer working and the problem persists even when the rotor is unloaded or fully loaded. It does not seem to stop at the same speed every time (it ranges from 200 rpm to 5-8 thousand rpm) before it will trip and return the Err 5 message. I am assuming that Err 5 relates to an unbalanced rotor but that is based on a gut feeling. Any help would be appreciated.
