No DC Power to Zodiak Component
The Zodiak control surface, which includes the Main and Menu panels,
and the Video Processor frame are powered by completely separate power
sources as described in this section. DC power can be interrupted or termi-
nated to any Zodiak component by blown fuses, defective or loose cabling,
or, in the case of the Video Processor frame, high temperature thermal shut-
down.
DC power to each Zodiak component in the system is clearly indicated on
every module or panel board. Use the block diagram in
bleshoot loss of DC power to any component in the system.
