Move the fader through its full travel to en-
sure it does not bind or scrape along the con-
trol panel slider cutout.
Console Display Service
The meter and the clock-timer boards are lo-
cated on the under side of the Console Display,
which is a subassembly that is fastened to the main
frame behind the control panels.
Removing the Console Display
The console display must be removed from the
frame to change display settings, to connect a mas-
ter clock or a remote timer reset cable, or to in-
stall the Quad Meter Package.
Each of these activities require accessing the
meter and clock-timer boards. The console should
be powered off while removing and reinstalling
the display assembly. Two padded surfaces (shop
towels, etc.) are required for this procedure.
To remove the console display:
1.
Flip-up the rear connector cover to access
the two 4-40 screws holding the reflector
in place. Remove these screws (rear corners
of the console display cover).
2.
Lift the reflector out of its slot. Handle by
its edges, and set it on a padded surface, to
protect its mirrored surface.
3.
Remove the console display cover screws
(either two or four 4-40 Phillips screws, top
rear ). Remove the console display cover by
lifting straight up.
4.
A smoked display window was sandwiched
between the display cover and the main dis-
play subassembly. Set it off to the side.
5.
Remove all of the console display subas-
sembly mounting screws (4-40 Phillips)
along the front of the subassembly. These
sit just above the control panels. Use care
when removing the screws.
6.
To protect the control panels and console
display subassembly, lay padded material
over the top half of the control panels. Lift
the console display subassembly up enough
to clear the frame, then rotate it forward to
lay it facedown onto the padded material.
The console display subassembly is con-
nected to the Monitor & Output board by
two cables. Do not strain these cables while
removing the subassembly and placing it
on the control panels.
SAFETY NOTE:
Touch the metal chas-
sis to dissipate static before adjusting
the multi-switches or plugging in a
cable to J4. Do not touch any compo-
nents on the boards other than the
multi-switches or connectors.
Reinstall the console display in reverse order,
making sure not to pinch any cables between metal
parts. Align the smoked display window holes with
the clock set holes. The cover display cover holds
the window in place.
CLOCK TROUBLESHOOTING
If the clock’s colons are flashing, it indicates the
clock has lost its ESE or SMPTE master time-
code signal. This signal plugs into J4 on the clock-
timer board. If the clock is set to run autonomously,
then verify that DS1-2 and DS1-5 are both set to
off. See page 2-9 for information on the clock and
DS1 switch settings.
Even though the ESE/SMPTE input on the
clock is balanced, polarity of the incoming signal
is important. If reversed, the master clock signal
will not be detected. The + or hot lead must con-
nect to J4, pin 5 and the - or shield lead must
connect to J4, pin 6.
