9.3 Troubleshooting and Maintenance
When a supply is in a fault condition it is important that the PA cabinet extrusion cover
in front of the supply be removed and the 3 LEDs on the front edge of the supply
control card be checked for fault status. This card is located at the top of the supply, it is
not behind a safety cover. The D connector on the front is J1, the power supply interface
to the transmitter control system. The 3 LEDs are to the left of the connector, it is
normal for them to flash on briefly when the supply is enabled by the logic. Removing
this D connector will not allow the supply to furnish 50 volts even with AC power
applied.
