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 understand and follow a ll the safety guidelines, safety instructions, warnings and

cautions mentioned in this manual.

WARNING: Be aware of su spended loads.

WARNING: Wear a hard h at to reduce the risk of p erson al injury.

WARNING: Be careful w hile working with heavy loads.

WARNING: Mind your ﬁngers w hile working with 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 precautions to prevent the incidence of

component damage c aused 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 then 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, deformation, corrosion, and any other c ircumstances that m ay effect the load

handling capability of the part.

• Both hands must be free for se rvicing T-20 tiles in a LED-wall. Therefore the use of a ladder to a ccess a tile is forbidden. Only

the us e of a s caffold or a Z-lift is allowed.

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

servicing or repairing to the display.

• In case o f rem oving an T-20 LED module out of a tile, ensure the module is secured with a safety cable to the LED-wall structure.

• Take the nec essary precautions to prevent water intrusion inside the T-20 tile due to weather conditions.

2.4 Startup sequence of an T-20 display system

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

Startup sequence:

1. Switch on the m ain po wer to the T -20 tiles.

Note: Nothing happens yet.

2. Power up the digitizer.

- The digitizer gener ates a START signal for the ﬁrst tile.

- The digitizer places video content, of the last selected input slot, on the data line t o the LED display.

3. The STA RT s ignal triggers the re-sync /controller unit of the ﬁrst tile to start up on the line voltage prov ided on the data cable.

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

- The gre en LED on the re-sync/controller un it 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 STA RT signal about half a seco nd before sending it to the next tile. Th is is necessary

to reduce the inrush current of the c omplete T -20 display. This delayed STA RT signal will activate the next tile and so on.

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

- The internal fans starts to turn.

5. The power distribution unit starts up.

- The po wer distribution unit generates +15V and +8V.

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

6. The controller starts up.

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

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

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

7. The controller unit starts to initialize.

- The ye llow LE D on the controller unit lights up c ontinuously.

- 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 s econd off) indicating the controller is c ompletely

and correctly initialized.

8. The LED driver receives data from the controller.

- The yellow LE D on the LE D drivers goes on.

9. The T-20 tile s hows video content.

3.1 T-20 re-sync unit diagnostic

Status LED’s on t he re-sync unit

The re-sync unit is provided with a yellow and a g reen status LED . These status LED’s are visible through the data output por t of

the re-sync unit, see illustration below. N ote t hat you have to unplug the data output of the re- sync unit to s ee the LE D’s.

The controller and re- sync circu its are b uilt on the same P CB board of the re-sync unit. The controller ﬁrm w are

and controller software include the functionality of the re-sync unit. So, the T-20 does not have a separate

ﬁrmw are ﬁle for the re-sync unit.

• Reference G : Green LED indicating the s tatus of the FPGA. Remains OFF until the FPGA is program med correctly. Continuous

ON during normal operation.

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

statuses of the processor.

a) Flash pattern:

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

b) Flash p attern:

Processor is running in boot mode because of incorrect main program ﬁle. The software of the controller must be upd ated.

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 i

s running in boot mode it is impossible to upda te the ﬁrmware of the controller.

(0.1 secon d ON — 0. 1 se cond OF F)

c) Flash pattern:

Error in conﬁguration of FPG A : Conﬁguration done but conﬁguration s tatus of FPGA not correct. The ﬁrmware of the c on-

troller must be updated. See user guide of the c ontrol software (e.g. Director toolset) for further instructions on how to

update the ﬁrmware of the controller. (2.5 seconds ON — 0.5 second O FF)

d) Flash p attern:

Error in conﬁguration of F PG A: Con ﬁguration done but watchdog FPGA is not functioning. The ﬁrm w a re o f the controlle r

must be updated. See user guide of the control software (e.g. Director toolset) for further instructions on how to upda te the

ﬁrmware of the controller. (0.1 second O N — 0.1 second OFF — 0.1 second ON — 2 seconds OFF)

e) Flash p attern:

Error in conﬁg uration of FPGA: FPGA is conﬁgur ed with backup ﬁle. Tile gives image, but OSD message “ﬁrm backup”

remains on screen until any other O SD comm and is given by the control software (e.g. Director toolset). The ﬁrm w are of

the controller must be updated. See user gu ide of the control software for further instructions on how to update the ﬁrmware

of the c ontroller. (2 s econds ON — 2 seconds OFF)

If an y FPG A error, best is trying to upload n ew controller FPG A co nﬁ g ﬁle (controller ﬁrmware). If problem

remains, replace re-sync unit.

3.2 Manual startup of the PSU

Why starting up the PSU manually?

To determine the cause of a malfunction T -20 tile it can be very interesting to exclude the possibility of a bad function PS U. Norm ally

the PS U receives a ’START’ signal from theRe-sync/controller unit via the pow er distribution unit. When this signal does not reach

the P SU, because for exam ple a malfunction Re-sync/controller unit, the PSU does not start up.

WARNING: Never install a T-20 tile permanently with a jumper 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 by experienced service perso nnel!

Necessary tools

Flat screwdriver.

Necessary parts

Jumper link.

How to startup the PSU manually?

1. Place a jumper link on J100 of the PSU.
