4.1 Component Location and Access
Reference Drawings:
Shop Drawings ...................................................................................... Refer to Appendix A
Each display contains an enclosure that includes the following devices:
• Display Driver
• 24V DC Power Supply
• 10V AC Transformer
• Signal Surge Board
• Signal/Power Input Termination Jacks
On the 10”display, all the components are behind one door. For 13”, 18”, and 24” displays, the
hinged doors swing outward when the two latches on the front display face panel are turned,
as shown in Figure 13. For larger displays, 36”, 48”, and 60”, access the enclosure by turning
the latches and opening one of the digits in the face of the display. Since component
placement varies slightly with each DataTime model; consult the specific model's Shop
Drawings.
