Hi everyone .
I have a Schindler 330A hydraulic with a LTI door operator and I am having difficulty completing a code learn. The number 1 on the door display is on constantly and because of this I cannot complete the code learn. The door is in constant nudging and it will run like this for a couple of days and then shutdown with the doors open and the nudging buzzer on. I have tried a couple of different things with the Mode button on.... ie holding the door open and close arrows at the same time. Once or twice I had the number 1 flashing... I have serviced the door tracks and little ramp etc. Any Suggestions would be greatly appreciated. Thanks in advance
