Mind Your Fingers
When servicing on site be aware of suspended loads, wear a hard hat to reduce the risk of personal injury. 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 cord 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 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 specific 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 come near the LED-wall during servicing.
• Inspect the complete LED-wall for security, wear, deformation, corrosion, and any other circumstances that may effect the load
handling capability of the part.
• Check the handles on the back of the tiles for loss of strength due to exposing to environmental conditions. Replace damaged
handles immediately before starting any servicing to the tiles.
• In case of removing a tile out of the LED-wall, ensure the tile is secured with a safety cable to the LED-wall structure.
• Incaseofr
eplacing a LED assembly of an SLite tile, ensure the LED assembly is secured with a safety cable to the SLite frame.
• Take the necessary precautions to prevent water intrusion inside the tile due to weather conditions.

2.4 Startup sequence of an SLite display system
The first two steps of the startup sequence are done manually.
Startup sequence:
1. Switch on the main power to the SLite tiles.
Note: Nothing happens yet.
2. Power up the digitizer.
- The digitizer generates a START signal for the first tile.
- The digitizer places video content, of the last selected input slot, on the data line to the LED display.
3. The START signal triggers the resync-unit of the first tile to start up on the line voltage provided on the data cable.
- The resync-unit transfers the START signal to an ON signal for the local SMPS.
- The green LED on the resync-unit remains off.
- The red LED on the resync-unit will only light up in case there is no video content present on the incoming data line.
- The resync-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 SLite display. This delayed START signal will activate the next tile and so on.
4. The ON signal from the resync-unit triggers the local SMPS to start up.
- The four internal fans starts to turn.
5. The power distribution unit starts up.
- The power distribution unit generates +15V and +8V.
- The +15V red LED and the +8V red LED goes on.
6. The controller unit starts up.
- The controller unit 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.
- The presence of the local +8V line voltage on the resync-unit lights up the green LED on the resync-unit.
7. The controller unit starts to initialize.
- The yellow LED on the controller 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.
