The indicator device 24 comprises a post 30 attached at a lower end thereof to the outer deck 20 and having a display housing 42 attached at angle at an upper end of post 30. The electronic display 52 is disposed in the display housing 42. A base 26 is disposed on the outer deck 20 with the post 30 passing through an opening in the base 26. A transparent enclosure 44 having upper and lower openings is disposed over the base 26, the post 30 and the display housing 42, with the display 52 disposed within the upper opening of the enclosure 44. A logic circuit 64 interfaces with the passenger conveying device 10 and the display 52 to determine the symbol indicative of the operational feature of the passenger conveying device 10 to be displayed.
