Power Supply Main Menu
If you press the Power Supply button on the control panel
overlay, it will take you to the screen shown in Figure 3-
16. The Power Supply Menu Tree is shown in Figure 3-32
on page 3-33.
This is the overall Power Supply metering screen for both the PA Power Supply, the
Low Voltage Power Supply Unit or LV PSU and the AC Mains. It is also the fault status
screen for the power supplies. A fault would cause one of the listed faults to be
highlighted red for fault or yellow for a warning condition.
System Faults:
•
AC Low - triggers if the AC input to the MOV board goes below 177Vac
•
AC High - triggers if the AC input to the MOV board is above 264Vac
•
MOV Fuse 1, 2 or 3 - turns yellow if one or more of the MOV protection
fuses on the MOV board is open.
LV PSU Faults are generated by the Vicor power supply unit and monitored by the PS
Monitor board. The dc voltage faults are triggered at +/-15% of nominal.
Figure 3-16 Power Supply Screen
The PAPS (Power Amplifier Power Supply) icon will turn red or yellow if any of the
faults on this screen are activated. Figure 3-16 shows the possible icon configurations
with red being critical faults and yellow simply a warning condition.
