Service manual
All Colorado Time Systems’ scoreboards are designed to operate on regular
115 VAC electrical current using a standard grounded wall outlet (G.F.I),
installed in accordance with National Electrical Codes and local
ordinances.
Note: We recommend that the electrical outlet be on a separate cir-
cuit with a separate dedicated ON/OFF switch, ideally with an
indicator light. The switch should be located in proximity to the
scoreboard but a height restricted from vandals. Since your score-
board uses a microprocessor control (miniature computer circuit),
just like your TV or stereo, your scoreboard is sensitive to noise on
the AC line. Insure that other electrical devices containing motors
are not placed on the same circuit as your scoreboard.
Maximum amperage is 2.3A. Maximum wattage is 60 watts. Under normal
operating conditions, power consumption will be less than 6 watts of
power. If you are installing 115 VAC power for your scoreboard, follow all
local and national codes with regard to wiring and safety precautions.
In order to operate your scoreboard, confirm that the ON/OFF switch,
located on the main control board, is in the ON position.
Note that the operator’s console also has a “SCOREBOARD ON/OFF” key
which simply turns the display on and off; however, this key does not
terminate electrical power from the scoreboard.
After using your scoreboard, the ON/OFF switch located on the main con-
trol board may be left in the ON position provided you do not have an
internal battery (as in Model P-1 or RT-1). We recommend that all outdoor
scoreboards have electrical power removed when the scoreboard is not in
use.
If you have purchased a scoreboard containing an internal 12VDC battery
(standards in Model P-1, P-2, RT-1, RT-2, RT-4, RT-5, SC-2 and SC-5),
observe the following operating procedures:
Although the scoreboard system contains a low battery indicator (opera-
tor’s console LCD displays “Lo b”), it is always wise to organize a system
of operation whereby you will never be faced with a low battery condition.
