Section 1 : Introduction

1.1 How To Use This Manual

This manual explains the installation and maintenance of the Daktronics CH-1036V & CH1436V auto racing display systems. For questions regarding the safety, installation, operation or service of this system, please refer to the telephone numbers listed on the cover page of this manual.

Important Safeguards:

1. Read and understand these instructions before installing.

2. Do not drop the control console or allow it to get wet.

3. Be sure the display is properly grounded with a ground rod at the display location.

4. Disconnect power to the display when it is not in use.

5. Disconnect power when servicing the display.

6. Do not modify the display structure or attach any panels or coverings to the display

without the written consent of Daktronics, Inc.

The box below illustrates Daktronics drawing numbering system. The drawing number “7087P08A-69945” is how Daktronics identifies individual drawings. This number is located in the lower-right corner of the drawing. This manual refers to drawings by listing the last set of digits and the letter preceding them. In the example below, the drawing would be referred to as

Drawing A-69945. Referenced drawings are inserted at the end of the first section which references them.

1.2 Display Overview

Reference Drawing: Models CH-1036V and CH-1436V ................Drawing A-78611

Refer to Drawing A-78611 for an illustration of the Daktronics CH-1036V and CH-1436V displays. These displays along with the Daktronics CHTS-300 timing console will show the car positions, time or lap number and the track status.

Section 2 : Installation

2.1 General System

Reference Drawing: System Diagram, CH-1036V & CH-1436V....Drawing A-78612

Refer to Drawing A-78612 for a general system layout.

The general procedure for installing the CH-1036V or CH-1436V display is as follows:

1. Dig the footing holes and install beams and footings.

2. Route power and signal cables to the display and control locations.

3. Mount the displays to the beams as described in Section 2.2.

4. Route power and signal wires into the displays as described in Section 2.3 and 2.4.

2.2 Display Mounting

Reference Drawing: Scoreboard Mounting....................................Drawing A-55101

Refer to Drawing A-55101 for an example of a typical mounting for the display.

Note: The bolts that secure the display to the beams do not go through the beams but run

along both sides of the beam, clamping the display to the beams.

A mounting kit consisting of mounting angles, channels and 1/2" hardware is provided to mount the display.

Each display consists of multiple sections. To install the display properly, the bottom section should be attached first followed by the rest of the sections stacked above it. Refer to

Drawing A-55101 for installing each section. To install the display:

1. Position the display against the mounting beams to secure the bottom of the display to the

beams as shown.

2. Next, secure the top of the display. Once mounting angles are attached, the display may

be slid up or down to the desired height.

3. Once positioned as desired, tighten all the bolts.

2.3 Control Signal Cable

Reference Drawings: Color Code, 25-Pin J-Box.............................Drawing A-47207

For the display, two conductors of 24 AWG, for distances up to 600 feet, or 22 AWG, for distances up to 1000 feet, are required.

Refer to Drawing A-47207 and the following table. At the control location, mount the signal J-box to a convenient location. Route the cables and connect to the wires leading from the connector in the cover.

At the display, open the hinged panel covering the entrance panel. Remove the cover from the entrance panel. Refer to Drawing A-78613 for the components inside the enclosure. Connect the signal wires to TB31 as indicated in the following table.

2.4 Power Wiring

Reference Drawing: Component Locations, CH-1036V&1436V....Drawing A-78613

Either CH-1036V or the CH-1436V display requires a 120/240 VAC, 50 amp circuit per line. With all lamps lit, the CH-1036V is capable of drawing a maximum of 40 amps on one line and 14 amps on the other line. The CH-1436V is capable of drawing a maximum of 40 amps on one line and 34 on the other.

Connect the power wires to TB41 in the entrance panel as labeled and as shown in Drawing A-78613.

2.5 Grounding

The display must be connected to earth-ground. Proper grounding is necessary for reliable equipment operation. It also serves to provide protection to the equipment against damaging electrical disturbances and lightning. If the following grounding methods are not adhered to,

the warranty will be void.

The steel support structure for the display cannot be used as grounding. The support is generally embedded in concrete, and if in earth, the steel is either primed or it corrodes, making it a poor ground. Use one ground rod at each display support column.

The National Electrical Code requires the use of a lockable power disconnect near the display. Provide a lockable disconnect switch (knife switch) at the display location so that all power lines can be completely disconnected. Use a 3-conductor disconnect so that both hot lines and the neutral can all be disconnected. This is important in protecting the display against lightning.

There are two considerations for power installation, New Power Installation and Existing Power Installation. These two power installations differ slightly, as described in the following paragraphs.
