Startup Sequence
Description and Pinning
Startup sequence AV3 in connection with the PSU of the Plasma:
1. Step
On CN801 of the PDP PSU, Pin3, +5VDC appears.
2. Step
CN801, Pin1 (ACDET) switches to ”high”, as soon as the voltage from the PSU becomes higher than 90VAC. If the
voltage remains under 90VAC, the startup will stop here (is interrupted by the AV3).
3. Step
To start the plasma, the signal RYLON (CN801, Pin2) is set to 5V, which causes the startup of the low voltages on the
PSU, as e.g. 5V, 12V, 30V, etc.
4. Step
The signal 5VDET (CN801, Pin6) is under surveillance. If the signal is ”low”, the AV3 will setRYLON = 0V (this causes
the switch off of the panel).
5. Step
On ”high”—signal (RYLON = 5V) the AV3 will set VSON to ”high” (CN801, Pin5) and will switch also the high voltages,
the panel is under operation.
