Dover Composite Optical Leveling PC Board : LUSENET : Elevator Problem Discussion : One Thread

Hi There, I have a number of these beauties on service and have seen a number of differant boards. There is the 1986 vintage 145557 board with 4 leds and a failure light then there is the 1994 vintage with 6 leds and 2 fault lights and a relay. Then there is the Denver elevator replacement boards. What are the problems with the old boards and what is best one to use. Thanks for your help
