Control Board Connector P111 to Y-SUS P101 Voltages and Diode Mode Checks These pins are very close together. Use Caution when taking Voltage measurements. Pins 1 through 3 Receive 16V from the Y-SUS. Protected on Y-SUS by FS204 Pins 4 through 7 Receive M5V from the Y-SUS. Protected on Y-SUS by FS202 Pin c P111 Label Silk Screen All the rest are delivering Y-SUS Waveform development and Y-Drive logic signals to the Y-SUS Board (Y-Drive logic signals are simply routed right through the Y-SUS to the Y-Drive boards). Note: The +16V is not used by the Control board, it is routed to the Z-SUS leaving on P101 Pins 1~2. The M5V also leaves on P101 Pins 3~4. 90 July 2010 50PJ350 Plasma
