Mark V ProVis Injection System

+5 VDC Overvoltage
Protection
+5 VDC overvoltage protection is provided by 6.2 VDC zener diode
D6, and 3.15 amp fuse F6. If the supply rises above +5 VDC, D6
begins to conduct and draw current. If voltage continues to rise, D6
will breakdown and short the +5 VDC supply to ground. The combina-
tion of voltage and current drawn when D6 shorts, will trigger F6 to
open, removing the +26 VDC from the PWM.
