Heads up for people that attempt to repair these. The encoder IS NOT AVAILABLE ANYWHERE!!! I have contacted Cole parmer as well as the encoder manufacturer Renco. So be very careful with them !

It was the setup featured in this thread... My first Masterflex. Ran nonstop for 10 years but had it stuffed in a small cabinet. I think heat took it's toll on the controller.

Does anyone know if this is the same fixed for a brushed motor? 7557-02.
Getting Error #3: Instantaneous Over-Current Description: Motor is drawing too much current for a short duration of time. Error Condition(s): The motor current is above 4.0 A peak. Actions: Drive will stop immediately. Verify that pump head is not binding and that the load is not above recommended maximum load. If error persists consult factory. Perhaps I'll just replace brushes first, but might be rear bearing? Opened front cover and saw little black dust settled. It will still run without the head on. |

Some photos of 7557-02 Motor. One of the bearings was seized and replacement was easy... however... I am now getting ERR 1 which seems to be encoder error. Not sure how to fix yet, but the encoder doesn't seem that delicate on this model.

WOW! It wasn't an encoder issue at all. TLDR: One of the brushes wasn't making contact with the motor, trouble going through the hole.
After letting it sit for a while and let my frustration go away and resist to send it in for "repair" and $$$, I tried to troubleshoot again. So I turned it on, and began turning the motor by hand right before pushing the Play/Start key, and while keep turning it by hand, after I pushed Play/Start key the RPM would actually readout the number for a second or two before going to Error 1. That gave me hope that it wasn't an encoder issue at all. So I opened the motor back up and troubleshoot the motor itself. I looked this video up real quick "How to troubleshoot brushed DC motor" https://www.youtube.com/watch?v=sWEsPw733h8 I put my multimeter on the positive and negative leads and got nothing. Tried the 9v battery and nothing. I took a closer look and ended up being one of the brushes wasn't fitting through the hole properly and no contact to the motor. After I verified both brushes making contact again, the multimeter was reading some resistance and the 9v battery made the motor run. All is good, no encoder issue, and save me some $$$. |
