About this chapter

Read this chapter attentively. It contains im portant information to prev ent personal injury while s ervicing an TF Series display on-site.

Furthermore, it includes several cautions to prevent damage to the TF Series tile. Ensure you understand and follow all the safety

guidelines, safety instructions and warnings mentioned in this chapter before performing any servicing on the TF Series display. After

this chapter additional “warnings” and “cautions” are give n depending on the servicing procedure. Read and follow these “warnings”

and “cautions” as well.

1. Safety

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 yo u understand and follow all the safety guidelines, safety instructions, warnings and

cautions mentioned in this manual.

WARNING: Be aware of suspended loads.

WARNING: Wear a hard hat to reduce the risk of personal injury.

WARNING: Be careful while wo rking with heavy loads.

WARNING: Mind your ﬁngers while working w ith heavy loads.

Safety precautions:

• Follow all s ervicing and safety instructions m entioned in the servicing procedures.

• Unplug the tile AC power c ord from the AC power source and wait about 10 minutes before start any servicing to the tile. This

to allow the capacitors to discharge.

• Some boards c ontains electrostatically sens itive devices (E SD). Take the necessary pr ecautions to pre vent the incidence of

component damage caused by static electricity.

• Do not modify and/or replicate any component. Barco uses speciﬁc materials and manufacturing processes in order to achieve

part strength. No other parts than B arco par ts are allowed.

Additional on-site servicing safety precautions:

• Fence off a restricted area of at least 3 meters arou nd the LED-wall using an eye-catching fence and “KEEP O UT ” signs. This

to prevent unauthorized persons coming near the LED-wall during servicing.

• Inspect the complete LED-wall for s ecurity, wear, deform ation, corrosion, and any other circumstances that m ay effect the load

handling capability of the part.

• Both hands mus t be free for s ervicing tiles in a LE D-wall. Therefore the use of a ladder to acc ess a tile is forbidden. Only the

use o f a scaffold or a Z-lift is allowed.

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

or r epairing to the display.

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

• Take the necessary precautions to prevent water intrusion inside the lie due to weather conditions.

2. General information

2.1 Service overview

Front and back access

A TF Series display can consist of two different types of tiles. Each type of tile can h ave front or ba ck access for service reasons.

Front access Back acces s

• Front access:

Front ac cess m eans that service on the TF Series tile happens from the f ront side of the tile. To access th

e components inside

the tile, several or all frames have to be removed.

• Back access:

Back access means that service on the TF Ser ies tile happens from the back side of the tile. To access the com ponents inside

the tile, one or two doors a re provided which can eas ily be opened us ing a quick lock.

2.7 Startup sequence of an TF Series display system

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

Startup sequence:

1. Switch on the main power to the TF Series tiles.

Note: Nothing happens yet.

2. Power up the digitizer.

- T he digitizer generates a START s ignal for the ﬁrst tile.

- T he digitizer places video content, of the last selected input slot, on the data line to the LE D display.

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

- T he re-sync/controller unit transfers the START signal to an O N signal for the local SM PS .

- T he green LED on the re-sync/controller unit rem ains off.

- T he 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.

- T he re-sync/controller unit delays the S TART signal about half a s econd before s ending it to the next tile. This is necessary to

reduce the inrush current of the complete TF Series d isplay. This delay ed START s ignal will ac tivate the next tile and so on.

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

- T he internal fans starts to turn.

5. The power distribution unit starts up.

- T he power distribution unit generates +15V and +8V.

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

6. The controller starts up.

- T he controller g enerates the local +5V and the local +8V line voltage.

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

- T he local +8V line voltage supports the line voltage on the data cable to s upply the resync-unit.

7. The controller unit starts to initialize.

- T he yellow LED on the controller unit lights up continuously.

- T he green LE D(s) on the controller unit starts lighting up after the FPGA (s) are conﬁgured.

- T he Yellow LED on the controller u nit s tarts to ﬂash (half a second on, half a s econd off) indic ating the controller is c ompletely

and correctly initialized.

8. The LED driver receives data from the controller.

- T he yellow LED on the LED drivers goes on.

9. The TF Series tile shows video content.
