Using # 264946 Front Cover to Replace
Broken # 266746, # 263832 or # 264461 Control Module Buttons
Broken # 266746, # 263832 or # 264461 Control Module Buttons
#
266746,
#
263832
or #
264461
control modules are often replaced when buttons
break, not for electronic failures. Replacing the #
264946
front cover when buttons
break instead of replacing the entire control module will save customers time and
money.

Broken control module
“buttons” occur when tabs
on front cover break. Use
plastic front cover when
replacing “broken buttons”.
Top of front cover
Bottom of front cover
Top tab
Note cracks in plastic locking tabs.
NOTE:
# 264946 front
cover fits on all three
modules -- # 266746, #
263832 & # 264461.
CAUTION:
Some pc board
components are sensitive to
static electricity and can be
damaged when touched.
Personnel handling pc boards
should be grounded.
CAUTION:
Insert display module board carefully to prevent
breaking spring locking tabs on front cover. When installing
display module, carefully slide top of board into top of front
cover, making sure board is fully seated into tabs. Then,
carefully rotate bottom of board into position so spring locking
tabs spring back and lock without cracking or breaking. DO
NOT FORCE bottom or top of display board into position.
INSTALLATION
:
To install a front cover, insert the
hinge tabs into the control module housing -- do NOT
force the cover into the housing. To insert the hinge
tabs, rotate the front cover (with the tabs contacting the
housing hinge) until the cover hinge tabs slide easily into
the hinge. When the hinge is in place, close the front
cover until all three tabs lock the cover in place.
HINT:
Use #
264946
front cover
instead of replacing an older #
263832
module with a #
266746
module since modules cost more &
have longer lead times than covers.
Many #
263832
modules have been
replaced merely for broken buttons.
NOTE: To determine which control module you have, check the model #’s on the following list:
266746 -- SHU 5302/5304/5305/5306/5312/5314/5315/5316/6802/6805/6806 UC 11 - UC/12, SHU 5307/5317 UC/12 and SHI
