Now here is my problem : equipment from 1970 -4 cars with a single dispatcher , car 1 , 2 , and 4 are working in a different way , they have to reach top or bottom floor to change direction , another words if u take the elev on the 5th fl trying to go down to the lobby , the car have to go all the way up to the top landing -does stop in the top floor but car door doesn't open stay there for 3 seconds and then goes down to answer ur call or any other one in the down direction hall or car station call, I don't have the prints is kind of hard to hit the problem cuz u need to check the cars operation after each adjustment and without prints is going blind !!😠😳 any ideas or experiences are welcome
