a substitute cable may void the warranty on the scoreboard!

2.2 Mounting

For permanent mounting to wall, see the enclosed installation drawing in Section 6.

2.3 Data Cable Installation

The MP-40 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.

2.4 Electrical connections

The MP-3913 timer requires a 120 VAC, 20 AMP circuit.

IMPORTANT !!!

To protect the MP-2002 control from damage, it is advisable to disconnect the

control and store in a dry secure area when not in use.

NOTE

This equipment is ETL (Electronics Testing Laboratories) CSA 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.

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 should show CODE .

Enter the two digit code (94) shown in the lower center window of the keyboard as in the

following example:

Push CODE 9 4 ENTER .

When the proper code has been entered, the console display will show ON .

3.3 Console Display

The 4 digit Liquid Crystal Display (LCD) shows the information entered from the keyboard.

removed from the scoreboard. Use extreme caution during troubleshooting or repair.

To avoid possible damage to equipment or personal injury, always turn off the main

power before removing the cover or replacing assemblies, or replacing lamps.

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.

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) Timers don't light and console doesn't work

(a) Check that the main power switch is turned on.

(b) Replace any defective or blown fuses.

(d) If the timer still doesn't light, check the transformer voltage going to pins 5 & 6 of the data

input connector 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, check the voltage again at the control console end of

the cable.

If the voltage is less than 8 VAC, check the cables and connectors.

If the voltage is between 8-12 VAC, see the replacement parts list for a control or transmitter

PCB assembly, and contact the Customer Service Department.

(B) Timer 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.

(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.

(a) Check for continuity between the timer and the junction box.

(b) If an open circuit is found, the problem is either the cable or a cable connection.

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 consult the parts list for a control console

and contact the Customer Service Department.

(D) The timer digits light, the console works, but there is no control of the timer.

(a) Check the voltage between the black and green wires in the junction box with a voltmeter

set on the 3 VDC or higher scale. The voltage should read somewhere between 2-3 VDC

when the console is working properly.

(b) If the voltage is 0 VDC contact the Customer Service Department for assistance.

(d) If the correct voltage also appears at the timer, see the replacement parts list for a receiver

PCB assembly.

(E) The timer 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 "C" into "B" and "B" into "C" 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 timer works, but some lights do not come on.

(a) Check for burned out lamps.

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.

(b) Check for a broken wire or bad connection on the 12 pin connector.
