• A relay, contactor, connector or wire fails or opens.
4.2.6 Low Voltage Power Supplies
Refer to 8-5. A vendor supplied low voltage power supply provides +5 VDC, ±15 VDC, and +24 VDC for use
throughout the system. The 220 VAC from the secondary of T1 is the supply voltage for the LVPS. A 250V 5
amp fuse is mounted on the power supply. The 5 VDC, ±15 VDC and 24 VDC lines are routed to the CPU PCB.
NOTE: The 24 VDC is routed to the CPU PCB and Shutter PCB.
The +5 VDC supply from the CPU PCB is also routed out to the LCD color display, and Shut-
ter PCB.
