Note each power supply is fitted with a 3-wire grounded AC cord
that should be plugged into a "clean" AC power source. That is, an AC
source that feeds only the control room audio gear. This source should
be a separate feed from those powering lighting, air-conditioning, or
any other non-audio machinery. The third pin ground wire of the AC
source should be tied to the central system ground point. Note that
while the AC power cord ground wire terminates at the power supply
chassis, it does NOT connect to the TV-80 console common; the
console itself must be grounded separately. (See previous section,
"System Ground".)
Failsafe Dual Redundant Supply
Wheatstone failsafe power supply systems use two separate rack-
mount power supplies for each piece of powered equipment. Though
either is capable of running a full load on its own, in failsafe operation
both units run in tandem: if one fails, the other takes over, assuring
uninterrupted operation.
In order for failsafe systems to perform as designed, always have
BOTH rackmount supplies powered up and connected to their associ-
ated equipment.
The “TV-80 Power Systems” chapter fully covers rackmount
installation and connection of failsafe supplies.
Energizing the Supplies
(1) THE CONSOLE – Assuming the TV-80 console mainframe is
properly placed and grounded, and its power supply correctly
rackmounted and connected to the console’s power interface module
rear panel, you may now energize the rackmount power supply by
plugging it into the AC mains and turning it on. The console's VU
meters will illuminate; individual module switches will assume factory
default settings.
(2) THE CONSOLE EVENT COMPUTER ACCESS PANEL –
Again, assuming the event computer’s PSR (SPS-180) power supply
is correctly rackmounted and connected to the rear panel connectors of
the event computer access panel at the console, energize the event
computer by pluggin in the power supply to the AC mains. The +5V DC
to DC converter, 32VC5-5 PCB, installed in the event computer.
(3) THE SMART SELECT CAGE – With the PSR (SPS-180)
power supply correctly rackmounted and connected, energize the
rackmount Smart Select Cage by plugging in the power supply to the
AC mains. The Smart Cage should energize, with its switcher LEDs
lighting to reflect the settings on the console’s associated overbridge
preselector panels.
The power feed recom-
mended in the text is often
installed and referred to in
studios as an “isolated AC
ground” outlet. It is usually
orange in color.
