1.1 Servicing safety instructions

WARNING: Servicingmustbedonebyauthorizedandqualified technical personnel only, which are thor-

oughly familiar with the product and all of the proper safety checks of this product.

Personal protection

WARNING: Ensure you un derstand and follow all the safety guidelines, safety instructions, warnings and

cautions mentioned in this manual.

WARNING: Be aware of suspended loads.

WARNING: Wear a h ard hat to reduce the risk of person al injury.

WARNING: Be careful while w o rking with heavy loads.

WARNING: Mind your fingers while working with heavy loads.

Safety precautions:

• Follow all servicing and safety instructions mentioned in the servicing procedures.

• Unplug the tile AC power c ord from the AC power so urce and wait about 10 m inutes before start any servicing to the tile. This
to allow the capacitors to discharge.

• Some boards contains electrostatically sensitive devices (ESD). Take the necessary precautions to prevent the incidence of
component damage caused by static electricity.

• Do not modify and/or replicate any component. Barco uses spec ific materials and manufacturing processes in order to achieve
part strength. No other parts then Barco parts are allowed.

Additional on-site servicing safety precautions:

• Fence off a restricted area of at least 3 meters around the LED-wall using an eye-catching fence and “KEEP OUT ” signs. This
to prevent unauthorized persons coming near the LED-wall during servicing.

• Inspect the complete LED-wall for security, wear, deformation, corrosion, and any other circumstances that may e ffect the load
handling capability of the part.

• Both hands must be free for servicing TF-20 tiles in a LED-wall. Therefore the use of a ladder to access a tile is forbidden. Only
the us e of a scaffold or a Z-lift is allowed.

• Do not use the stacker system of the LE D-wall to climb into the TF -20 display. Always use a scaffold or Z -lift to perform any
servicing or repairing to the display.

• In case of removing an TF-20 LED m odule out o f a tile, ensure the module is secured with a safety cable to the LED-wall
structure.

• Take the necessary precautions to prevent water intrusion inside the TF-20 tile due to weather conditions.

2.7 Startup sequence of an TF-20 display system

The first two steps of the startup sequence are done manually.

Startup sequence:

1. S witch on the main power to the SLite tiles.

Note: Nothing happens yet.

2. P ower up the digitizer.

- The digitizer generates a START signal for the first tile.

- The digitizer places video content, of the last selected input s lot, on the data line to the LED d isplay.

3. T he START signal triggers the re-sync/controller unit of the first tile to start up on the line voltage provided on the data cable.

- The re-sync/controller unit transfers the START signal to an ON signal for the local SMPS.

- The green LED on the re-sync/controller unit remains off.

- The red LED on the re-sync/controller unit will only light up in case there is no video content present on the incoming data line.

- The re-sync/controller unit delays the START signal about half a second before sending it to the next tile. This is necessary
to reduce the inrush current of the complete TF-20 display. This delayed START signal will activate the next tile and so on.

4. T he ON signal from the re-sync/controller unit triggers the local SMPS to start up.

- The four internal fans starts to turn.

5. T he powe r distribution unit starts up.

- The power distribution unit generates +15V and +8V.

- The +15V red LED and the +8V red LED g oes on.

6. T he controller starts up.

- The controller generates the local +5V and the local +8V line voltage.

- The +5V red LED on the controller unit goes on.

- The local + 8V line voltage supports the line voltage on the data cable to supply the resync-unit.

7. T he c ontroller unit starts to initialize.

- The yellow LED on the c ontroller unit lights up continuously.

- The green LED(s) on the controller unit starts lighting up after the FPGA(s) are configured.

- The Yellow LED on the controller unit starts to flash (half a second on, half a second off) indicating the controller is completely
and correctly initialized.

8. T he LED driver receives data from the controller.

- The yellow LED on the LED drivers goes on.

9. T he TF -20 tile shows video content.

About this chapter

This chapter helps you to un derstand the status of the TF-20 Re-s ync/controller unit and describes how to start up the TF-20 power
unit manually. With this procedure you can check the good working condition of the power unit.

3.1 TF-20 re-sync unit diagnostic

Status LED’s on the re-sync unit

The re-sync unit is provided with a yellow and a green status LED. These status LED’s are visible through the data output port of
the re-sync unit, see illustration below. N ote that you have to unplug the data output of the re-sync unit to see the LED’s.

The controller and re-sync circuits are built on the same PCB board of the re-sync unit. The controller firmware
and controller software include the functionality of the re-sync unit. So, the TF-20 does not have a separate
firmware file for the re-sync unit.

• Reference Y: Yellow LED indicating the status of the processor. The flash pattern of the yellow LED indicates five different

statuses of the processor.

a) Flash pattern:

Normal operation of the processor. (0.5 second O N — 0.5 second OFF)

b) Flash p attern:

Processor is running in boot mode because of incorrect main program file. T he software of the controller must be updated.
See user guide of the control software (e.g. Director toolset) for further instructions on how to update the software of the
controller. Note that when the processor is running in boot mode it is impossible to upda te the fi rmware of the cont ro lle r.
(0.1 second ON — 0.1 se cond OFF)

c) Flash pattern:

Error in configuration of FPGA : Configuration done but configuration s tatus of FPGA not correct. The firmware of the con­troller must be updated. See user guide of the control software ( e.g. D irector toolset) for further instructions on how to
update the firmware of the controller.

d) Flash p attern:

Error in configuration of FPGA: Configuration done but watchdog FPGA is not functioning. The firmw a re o f the controller
must be updated. S ee user guide of the control software (e.g. Director toolset) for further instructions on how to update the
firmware of the controller. (0.1 second ON — 0.1 second OFF — 0.1 seco nd ON — 2 seconds OFF)

e) Flash p attern:

Error in config uration of FPGA: F PG A is configured with backup fi le. Tile gives image, but OSD message “firm backu p”
remains on screen until any other OSD comm and is given by the control software (e.g. Director toolset). The firmware of
the controller must be updated. See user guide of the control software for further instructions on how to update the firmware

3.2 Manual startup of the PSU

Why starting up the PSU manually?

To determine the cause of a m alfunction TF-20 tile it can be very interesting to exclude the possibility of a bad function PSU. Normally
the PSU receives a ’START’ signal from theR e-sync/controller unit via the power distribution unit. When this signal does not reac h
the PSU, because for example a malfunction Re-sync/controller unit, the PSU does not start up.

WARNING: Never install a TF-20 tile permanently w ith a ju mp er link on J100).

WARNING: RISK OF ELECTRIC SHOCK. First, always disconnect the main power before initializing this pro-

cedure. This procedure can only be performed b y experienced service personnel!

Necessary tools

Flat screwdriver.

Necessary parts

Jumper link.

How to startup the PSU manually?

1. Remove the PSU cover by releasing all nuts using a 7 mm nut driver.

2. P lace a jumper link on J100 of the PSU.

8.1 Cleaning TF-20 tiles

Why clean TF-20 tiles?

Due to outdoor use the TF-20 tile is exposed to all kinds of weather conditions. Sand, dust, smog and other dirt adhere on the TF-20
tile and therefore the visual performance of the TF-20 display is reduced. That’s why cleaning the TF-20 tiles is recommended at
regular intervals.

Image 8-1
Cleaning LED’s and shaders.

Always clean all tiles of the LED-wall to avoid brightness differences between cleaned and uncleaned tiles.

Necessary tools

• Vaporizer with a window cleaning product.

• Soft hand brush with long hair (recommended 4 cm pure pork hair).

• Garden hose with a spr ay nozzle.

• Compressed air.

How to clean TF-20 tiles?

1. S eal up the data and power sockets using a power and data linking cable. Make sure that all plug holder clamps are locked firmly.

2. Vaporize through different directions the window cleaning pr oduct on the shaders and LED’s.

Caution: Do not use industrial grease removers. Use only materials or chemicals that are inert, nonabrasive, noncorrosive

3. B rush down all dirt of the LE D’s and the shaders using

Caution: Do not use a hard bristled brush.

4. Wash away the remaining soap with plenty of fresh water.

Caution: Do not s ubmer ge the tile fully or partly in water or other liquids.

5. Repeat from step two until the tile is clean.

6. B low the surface dry with compressed air.

and non-marking.

a soft hand brush.

The TF-20 tiles can also be cleaned while they are mounted. A solid scaffold or Z-lift is required to do so. Start
cleaning from top row to bottom row using the above procedure.

8.2 Replacing the dust filters

High density dust filters

Both TF-20 tiles are equipped with at least one high density dust filter. These dust filters are located at the inner side of the tile.
Barco offers a spare kit with dust filters.

CAUTION: The high density dust filters of the TF-20 tile must be replaced on a regular basis, depending on

the environment conditions of theTF-20 display.

How to replace the dust filters of the TF-20 tiles?

1. Consult "Service components of a 3x1 tile", p age 7, "Service components of a 3x2 tile", page 8 to locate the dust filters inside
the TF-20 tile.

8.4 Color calibration

Color calibration of a TF-20 display

To achieve color uniformity among all tiles of the same disp lay, the tiles have to be color calibrated. This is done in factory but due to
service intervention like replacing LED-frames, TF-20 controllers or even complete tiles, it’s recommended to re-calibrate the TF-20
display on site. Refer to the user guide of the control software for more info about color calibration and calibration instructions.

B. ON SCREEN DISPLAY MESSAGES

General

A TF-20 display can generate and display several “On Screen Display” (OSD) messages regarding parameter statuses of the display.
Most of those messages can be displayed on request via the RMS-1 software. Other OS D m ess ages are automatically displayed in
case an error occurred. Most OS D messages are displayed for a time period of 10 seconds or continuous, depending the software
settings.
