I have 2 Schindler 330a controllers on my route with a door operator I haven't seen anywhere. It has a small "box" where the door motor is usually mounted, big heat sink on the side facing the cartop. On top of the box there are several buttons, "mode, plus, minus, open, close, and several led's for door open, door close, etc. There is no model number or any identification on this operator. Took the covers off and the motor/encoder appear to be connected inside the case. Have not had problems with them yet. Does anyone know how to access parameters, learn cycle, or any other functions this unit may have. Sooner or later, I'm going to have problems, trying to jump start the learning curve in advance! Thanks to all. I don't know how "newbie" got put by my name, but I can assure you I'm not a newbie....been in the trade for 15 yrs. and going strong!
