2. INSTALLATION
2.1 General Information
Shipping papers accompany each scoreboard. Check carefully to see that you receive
the following:
1 ea Black Flag Display
1 ea Control Console
1 ea Service Manual
1 ea Mounting Hardware Package
1 ea Junction Box
? ft Control Cable (if ordered)
IMPORTANT!

2.3 Pre-Test
Before installing the counter, pre-test all functions.
2.4 Installation
Select the location best suited for visibility by the majority of spectators. Preferred position is
facing east or north to avoid direct sunlight on the face of the scoreboard, if day use is planned.
The MP-40 direct burial data cable carries only low voltage signals and therefore can be
installed with or without conduit. consult section 6 for junction box and scoreboard wiring.
2.5 Electrical connections
This counter requires a 120/V. 60 HZ 3 wire with ground 20 AMP service at the
display for the exclusive use of the Black Flag Display.
NOTE
To protect the MP-2002 control from damage, it is advisable that you disconnect the
control and store in a dry secure area when not in use.
NOTE
This equipment is UL and NRTL approved and complies with the requirements in
part 15 of the FCC rules for a class A computing device. Operation of this
equipment in a residential area may cause unacceptable interference to radio
and television reception, requiring the operator to take whatever steps are
necessary to correct the interference.
3. CONTROL CONSOLE OPERATION
3.1 Display Power
Turn on the branch circuits to the Black Flag Display. The display will show "00".
3.2 Console Power
Plug the control console cable into the Press Box junction box.
Push ON/OFF once to turn the console on.
Push ON/OFF a second time to shut the console off.
When first turned on; the console display (LCD) should show CODE .
5

Enter the two digit code (94) as in the following example:
Push CODE 94ENTER .
When the proper code has been entered, the console display will show "0" .
3.3 Console Display
The Liquid Crystal Display (LCD) shows what the counter shows.
3.4 Black Flag Control
The Black Flag Number can be changed in following ways.
(A) To post a car number: Push CAR # followed by the car's number, then ENTER
.
Example: You want to Black Flag car 152,
Push: CAR # 152ENTER .
(B) To clear the display: Push BLANK . Three dashes show when the display is blanked.
(C) When the display is blanked and you want to put up another car number, enter the car
number, and then push blank again to relight the scoreboard.
3.5 Dimmer Operation
Push the DIM key to alternately dim and brighten the lamps, for day/night use.
4. MAINTENANCE AND TROUBLESHOOTING
4.1 Introduction
This section gives maintenance and troubleshooting information. Included are troubleshooting
guides for typical scoreboard malfunctions. If the cause of a problem cannot be determined,
please contact the customer service department.
4.2 Test Equipment
A simple analog or digital voltmeter will be sufficient for all user repairable problems. Printed
circuit boards requiring troubleshooting should be returned to the factory.
6

IMPORTANT !!!
In this scoreboard the 120 volt line is on the lamp socket all the time, and the
common is switched to turn the lamps on and off. For this reason, to avoid
damage to the equipment or personal injury, it is important to turn the main
power off when changing the lamps.
WARNING
120 VAC wires are exposed whenever the cover over the controller assembly
is removed from the scoreboard. Use extreme caution during troubleshooting
or repair. To avoid possible damage always remove power before removing
the cover or replacing assemblies.
4.3 Troubleshooting
Whenever possible, follow the troubleshooting guides prior to contacting the customer service
department. If a problem not described in the guides exists, contact the customer service
department immediately. Refer to the diagrams provided for assistance in troubleshooting
scoreboard malfunctions.
4.4 Troubleshooting Guides
(A) Scoreboard doesn't light and console doesn't work
(a) Check that the main power switch is turned on.
(b) Replace any defective or blown fuses.
(c) Check the power connections and voltages at the scoreboard.
(d) Contact the customer service department.
(B) Scoreboard digits don't light, but the console works
(a) With the main power switch "off"; remove the cover over the controller assembly.
(b) Check all connections.
(c) Turn the main power on.
(d) If the scoreboard still doesn't light, check the transformer voltage going to the receiver
PCB (printed circuit board) assembly (blue wires) using a voltmeter set on the 12 VAC
or higher scale.
If the voltage is less than 8 VAC contact the customer service department.
If the voltage is between 8-12 VAC see the replacement parts list for a receiver PCB
assembly, and contact the customer service department.
7

(C) The scoreboard digits light but the console doesn't work
(a) Check for continuity between the scoreboard and the junction box.
(b) If an open circuit is found, the problem is either the cable or a cable connection.
(c) If the continuity test checks good, check the voltage between the green wire and the white
wire in the junction box, using a voltmeter set on the 12 VAC or higher scale.
If the voltage is 0 VAC see the controller parts list for a transformer assembly.
If the voltage is less than 8 VAC consult the controller wiring diagram for instructions
on long cable compensation.
If the voltage is between 8 VAC and 12 VAC contact the customer service department.
(D) The scoreboard digits light, the console works, but there is no control of the scoreboard.
(a) Check the voltage between the black and red wires in the junction box with a voltmeter
set on the 3 VDC or higher scale. The voltage should read somewhere between2-3 VDC
when the console is working properly.
(b) If the voltage is 0 VDC contact the customer service department for assistance.
(c) If the voltage is correct, (2-3 VDC) check that this reading also appears at the scoreboard.
(d) If the correct voltage also appears at the scoreboard, see the replacement parts list for a
receiver PCB assembly.
(E) The scoreboard works, but some lights stay on all the time
(a) With the main power "OFF", switch the plug from the bad digit with the plug for a
known good digit.
EXAMPLE: Plug "A" into "B" and "B" into "A" locations.
(b) Turn the power back on. If the same lamps remain lit all the time, the problem is a
shorted lamp socket. If the lamps on a different digit now stay lit all the time, the
problem is on the driver PCB assembly. See the replacement parts list for the proper
replacement part.
(F) The scoreboard works, but some lights do not come on.
(a) Check for burned out lamps.
(b) Check for a broken wire or bad connection on the 12 pin connector.
(c) See the replacement parts list for the proper replacement driver board.
