Daktronics SQ-2001, Display Manual

Page: 13 / 38

CAUTION: Only qualified individuals should terminate power and signal cable and access the
electrical components of the display and its associated equipment. It is the responsibility of the
electrical contractor to ensure that all electrical work meets or exceeds local and national codes.
Daktronics engineering staff must approve all changes or the warranty will be void.
Each scoreboard features a 120 V AC power cord with a three-prong plug. Install a grounded
receptacle near the equipment so that the power cord can easily reach it. The control console
requires a 120 V AC receptacle and uses less than 1 A of power.
Displays operating on 230 V AC are also available, and they are shipped equipped with a
universal power plug.
Connect the scoreboard to earth ground. Proper grounding assures reliable equipment
operation and protects the equipment against damaging electrical disturbances and lightning.
Daktronics recommends a resistance-to-ground of 10 ohms or less. The electrical contractor
performing the electrical installation can verify ground resistance. Daktronics Sales and
Service personnel can also provide this service. The grounding connection on the power
cord‟s three-prong plug connects to the shell of the scoreboard.
Note: The customer must properly ground the outlet according to local and national
codes. Failure to ground the outlet voids the warranty for the scoreboard.
The scoreboard performs a self-test each time that power is turned on and the control console
is powered off or not attached to the scoreboard. If the control console is attached and
powered on, the self-test does not run, and data from the control console is displayed on the
scoreboard after a brief period of time. Each scoreboard self-test pattern will vary depending
on the scoreboard model, the number of drivers and types of digits.
If a radio receiver is installed, the radio broadcast settings (“b1”) and the channel settings
(“c1”) will be displayed in the Home and Guest digits during the POST. These values must
match the settings in the All Sport control console (refer to the appropriate control console
manual listed in
Section 1.4 ).
