Friends, I have a set of er40 ( reversible) controlled by a GS200. One motor in one of the retracts went faulty and I ordered a new one. Its installed now, but a I face a strange problem in that retract. It is moving opposite to the other two. I have checked everything I the tr union is installed in the proper way. I did not find anyway option in GS200 to prevent this . Or to reverse one retract. Can anyone help?
