3. Installation requirements

This chapter covers requirements for installation, power supply and the control system of

display.

Overview

§ Mechanical requirements

§ Electrical requirements

§ System requirements

3.1 Mechanical requirements

display comes with its own structural frame which makes installation simple and easy. Besides, it requires a strong and reliable supporting frame at the back to hold the display firm. Wherever this supporting frame is to be installed, on the ground, onto the pole or on a wall, attention should be paid to the following few points:

1. The display should be installed in a place that allows a clear and complete view of the display.

2. The supporting frame has to be strong enough to prevent the display from tumbling.

3. The installation site must have the strength to withstand the total weight of the display plus its structural frames

4. The display is meant for indoor use only. The ambient temperature, dust and ventilation, esp. that at the back of the display must be considered when one is choosing the installation site.

A typical way of mounting display onto a wall:

3.2 Electrical requirements Power requirements

§ A display works on AC 200-240V, 50~60Hz. Each column of the display has an independent power supply circuit and can thus be powered by electricity from different phases.

§ When the max. power consumption of display is less than 3KW, the display can be powered by single-phase power supply circuits which include a live, neutral and ground wire. Each circuit is controlled by an independent air-break switch.

§ But if the maximum consumption of the display is over 3KW, it should be powered by 3-phase power supply circuits c/w a live, neutral and ground wire. The 3-phase power distributes power to tiles of each column on an average level. A PSU (power supply unit) is used to control the power.

§ The block can also be powered by AC100-125V, 50~60Hz power supplies. But this needs to be specified in the production order so that it can be pre-set before going out of factory.

Grounding

The display shall be grounded at the installation site. If the existing power supply circuit cannot provide a good ground wire or does not even have one, it ’s a must to set or reset a reliable ground wire for the display. Good grounding will enable the display to work properly and can prevent it from being disturbed by surge.

5. Installation

This chapter describes the various installation methods of

display.

Overview

§ Preparing the supporting back structure

§ Mounting the extrusion frame

§ Fixing the Tile

§ Other types of supporting structure

5.1 Preparing the back supporting structure

Connect the top and bottom main extrusion of display to its back supporting structure by connection plates This is usually how the display is installed.

Typical mounting of display:

The back supporting structure is usually built on a wall or sits on a pole on the ground. Depending on the size of the display and space available installation site, there can actually be many ways of preparing the supporting structure. Below are some typical back supporting structures for clients’ reference:

a

CAUTION: If the display is to be mounted on a wall, one has to consider the withstanding capability

of the wall. In such a case, it ’s usually advised to install the display onto the structural

column of the wall.

TIPS ：Connection positions on the back supporting structure must match those on the

display. The manufacturer can provide the back supporting structure or the connection part for the client, but only on the condition that the client fully informs the manufacturer of conditions in the installation site.

5.2 Mounting the extrusion frame

After mounting the tiles, installation of other structural frames are to follow.

5.2.1 Assembling the extrusion frame Necessary tools

§ 8mm open-end wrench

§ 8mm box-end wrench

§ 8mm hexagonal key

§ 6mm Cross head screw driver

§ Modular tool

Broadcast Indoor

www.pledco.com

21

Connect the 4 sides of the main extrusion on a flat ground. Insert corner blocks onto the connection positions of the main extrusion. Screw them in a loose manner.

Mount the pole extrusions in the middle of the frame and mount their screws. With the aid of a Modular tool, find the right position for the screws and screw them tight. Then screw the 4 corners of the Main extrusion tight.

CAUTION: All screws on the frame must be fastened when installation is finished.

condition.

TIPS：In occasions where the installation site doesn’t allow use of a Crane while the frame is too big

for human operation, one can try the following installation method:

§ Mount the top horizontal Main extrusion onto the back supporting structure and fasten the screws.

§ Then mount the Main extrusions on both sides and fasten their tops with the top horizontal extrusion.

§ Lay the Pole extrusions in place. Screw their tops with the top horizontal extrusion in a loose manner.

§ After all the Pole extrusions and the side Main extrusions have been installed and hang vertically,

www.pledco.com

23

one can start to mount the Main extrusion on the bottom.

§ With the aid of a Modular tool, fasten the screws on the top of the Pole extrusions and then those at the bottom. Then fasten the connection screws of the bottom Main extrusion. Last, connect the bottom Main extrusion with the back supporting structure fast.

5.3 Fixing the display

Before mounting the display, attention must be paid to the following few things:

§ Make sure that the frame of the display has been properly connected with the supporting

structure, that everything is in good condition on the horizontal and vertical direction of the display and that the installation surface is flat and even.

§ Check if the tiles are installed in their exact positions with the help of a Modular tool.

Installation of the tiles starts from the middle column from bottom to top and then towards both sides.

Broadcast Indoor

www.pledco.com

24

How to fix tiles onto the frame:

There is a handle at the back of each tile. Before mounting a tile, turn its handle by 90°anti-clockwise to draw back the locks at the back of the tile. Lay the tile in its exact position. Make sure connectors on the tiles match those on the pole extrusion. Turn the handle by 90°clockwise to lock the tile firm on the pole extrusion.

On the other hand, a P series tile is fixed onto the pole structure with 4 M6X12 screws at its back. While fixing the tile, one must make sure the connectors match the connection positions on the pole. After all tiles have been mounted, cover the pole extrusions with cover plates.

CAUTION: For a front-serviced display whose back is unapproachable, cables must be connected

before the tiles are mounted.

TIPS: One can stand in front of a front-serviced display and reach his hand to the back of the tiles

to operate on their handles so as to mount them. However, he has to operate by putting his hand between the wall and the display to mount the last tile. Therefore some space must be kept between the wall and a front-serviced display, so that one can easily put his hand in to mount or maintain the last tile.

www.pledco.com

25

After all tiles have been mounted, it’s time to mount the Cover extrusions. Fix the Cover extrusions with the Main extrusions with M4X12 screws. Or one can drill holes on both extrusions with a drill that has a 3.5mm bit and then use 4mm self-tapping screws to fix them together.

5.4 Other mounting methods

A display can also be installed in other ways depending on clients ’ actual application of the display.

Below are some typical examples:

Hanging the display in air

6. Cabling a display

This chapter covers the system cabling of display. Overview

§ System cabling

§ Grounding

§ Pixel limitations

The power and signal connection between tiles have been taken care of while the tiles are being mounted. Therefore one needs to do the system cabling only after having finished mounting the tiles.

6.1 Cabling an on-line display

An on-line display can display various kinds of video files, such as AVI, MPEG2, etc., or can be directly connected to various kinds of live video sources.

An on-line display system wiring diagram

Example of an on-line display

6.2 Cabling an off-line display

An off-line display system is usually used to display graphics or images, or even video files for advertising purposes. It is especially useful for an interconnected digital billboard network.

Broadcast Indoor

28

An off-line display system wiring diagram

Example of an off-line display

TIPS: The LDU has to be laid close to the display. It can be put behind the display or somewhere

else nearby. The signal cables and power cables of the tiles can be hidden inside the Main extrusions.

Broadcast Indoor

www.pledco.com

29

TIPS: Signal cables from the LDU and power cables from the PSU (or directly from commercial

power) are usually connected to the display at its bottom. However, if otherwise required, for instance, if the display is to hang in the air, the cables can be rearranged to be connected from the top of the display. But this must be specified with the Manufacturer before the production order is placed.

6. 3 Pixel limitations

The display system supports a dot matrix resolution of up to 1920X1080 pixels. However, the signal distribution system LDU only supports up to 1024X768 pixels. That is to say, an LED display larger than 1024X768 pixels would need a special LDU connection arrangement.

6.3.1 Limitation of signal connection

Due to the pixel limitation of the LDU, an LED display larger than 1024X768 pixels would need more than one LDU to support distribution of signals. When multiple LDUs are connected together, the right starting point of each LDU on a picture must be appointed and preset.

Example: Signal connection of a display with 1280X768 pixels

Broadcast Indoor

www.pledco.com

30

6.3.2 Limitation of power connection

As a rule, each column of tiles of an LED display is connected by an AC power cable to the PSU for

power supply. However, if the display is extremely large and comprises of more tiles than could be supplied by one power cable due to current restriction, it becomes necessary to use multiple power supply cables which need to be connected to different power output terminals at the PSU.

Example: Power supply connection of a display with 960X600 pixels

7. Maintenance

Overview

§ Firmware update

§ Replacement a Tile of display

§ Replacement a unit control board

§ Replacement a power supply

§ Replacement a LDU control board

7.1 Firmware update

Control boards in both LDU and display unit may need firmware updating in actual use.

7.1.1 LDU firmware update

There are 3 ways to update the firmware on the control board QS5800 in the LDU:

1. Use the update package QS5800_update packet_verxx.xx_(year/month/date).rar to update the firmware

Steps: connect the display to a PC via an Ethernet cable, decompress the package in the PC,

and double click the update.bat in the file to start the automatic update process.

2. Use the update package QS5800_update packet_verxx.xx_(year/month/date) (for USB).rar to update the firmware

Steps: decompress the package in a USB disk, connect the disk to the QS5800 control board

and the update process will start automatically.

3. Use the update file xxxx.cpu.

Steps: Log onto the software Sigma 3000, choose Tool---Update---Update CPU and then select

the file xxxx.cpu to start the update process.

7.1.2 Updating the display unit controller firmware

There is a QS5242 control board inside the power box of each Unit. Following steps shall be observed to update the firmware on these control boards:

Log on the software Tools and choose “Maintenance” where you can choose a certain Unit address or choose All Units for updating the firmware on their control boards.

Select the following files in sequence for updating: File xxx.bin -----the CPU program for the control board. You can find it in the File Style menu presented as “CPU program for tiles”; File xxx.bin -----the data file of the control board. It can be found in the File Style menu presented as “Drive Board data”; File xxx.rbf -----the FPGA program for the control board, presented as “FPGA for tiles” in the File Style menu; File xxx.rbf -----the gamma data of the control board which can be seen as “Gamma Data for tiles” in the File Style menu; File xxx.bin -----the brightness data of the control board, presented as “Brightness Block of tiles” in the File Style menu.

TIPS：In order to make it convenient for the operator, a few definitions are given below for operation

of the screws. Unfasten：It means loosening the screw halfway. Do not unfasten completely or remove the

screw.

Unscrew：It means completely unfastening the screw. But because the screws are of an

un-detachable type, there is no need to worry about the screw dropping to the ground.

Remove：It means removing the screw completely. Care should be taken of not to let the

screw drop to the ground or get lost.
