cover; it's held in place by round stamped bosses
at each end. With the fader sitting label up and
the connector pins to the front, you'll see a pry-
point on the right end of the fader cover (Figure
C-18). Use a jeweler's screwdriver to gently pry
off the cover.
8.
Use a dry cotton swab, or a cotton swab wet with
distilled water, to clean the fader parts.
Note: The use of chemical cleaners on the con-
ductive plastic will substantially shorten fader
life. Never touch the fader slider contact fingers
while cleaning the fader parts.
Always use a clean dry swab to dry off the con-
ductive plastic tracks after cleaning. If the fader
rails are noticeably dirty, wipe them off using a
dry cotton swab before lightly lubricating the top
rail with Dow Corning 510.
Figure C-19: Cleaning the fader glide rails
If coffee, a soft drink or other sugared liquid has
been spilled into the fader, remove it from the
module as soon as possible and remove the top
cover of the fader. Hold the fader under hot run-
ning water while moving the fader slider back and
forth to dissolve the sugars and other chemicals.
Thoroughly dry the rails and conductive plastic
using dry cotton swabs and then lubricate the top
fader rail with Dow Corning 510.
Lubricating the Glide Rail
Move the fader slider to the middle of its travel and
place one drop of Dow Corning 510 lubricant on the top
rail on either side of the fader slider bushings. Move the
slider through its full travel to distribute the lubricant.
Wipe off any excess lubricant from the rubber stops at
each end of the glide rail. Normally only the top rail (the
one the fader slider bushings glide on) requires lubricant.
Reinstalling The Fader
1.
Snap the cover onto the fader body.
2.
From below, reinsert the fader into position in the
surface, taking care that the end marked
stalled adjacent to the channel's
3.
Reinstall the hex screws from the top of the sur-
face. Do not overtighten.
4.
Press the fader knob firmly onto the stem.
5.
Reconnect the fader leads to their mating pins on
the bottom of the fader. The sequence is:
*
Green wire to pin "2"
*
Black wire to pin "C"
*
Red wire to pin "1"
*
Bare wire to pin "G"
6.
Reconnect the RJ-45 patch cable and alpha panel
ribbon cable to the module.
Note: The ribbon connector must be connected
to the module "tail-up", with the cable emerg-
ing from the connector toward the top of the
module.
7.
Lay the module into the frame, engaging the lo-
cating tab at the bottom of the module and tilt-
ing the top downward into the frame. Be careful
not to pinch the ribbon cable between the module
and frame.
8.
Reinstall hex-head screw(s) at top of module.
