3 stop front and rear, door operator is a 6970 with the rheostats? front doors work fine no issue. rear doors.....if the car is at another floor and you hit the rear hall call the elev. will come get you and the door seam to work ok untill you break the light ray(older lamda bigger silver box) the doors will stall untill door protection drops then the will close no reopen? or if you say ride the elev. up to or down to a floor walk out and let the doors shut they will not reopen with a hall call. or if you stay in the elev. will not open with a RDO button. voltage checks and the "reactor" circuit shows a standing voltage of 35 volts, in the normal state when the elev. arrives and the doors open the voltage go up to 76 voltsandthen drops back to the standing voltage. when the doors fail the voltage drops to almost zero and them back up to 35 volts we have been over the controller and the door oper. but sometimes the issue just goes away for a few days. seams like a short somewhere but why only when the elev. is at the floor or when you break the beam/ reopen? i know i am over looking something but?????
