Operating Procedure
Assuming the previous installation instructions have been completed and
cautions noted, and the power amplifier is ready to receive a properly modulated
RF signal, proceed with the following steps to place the system in operation. The
power amplifier has been factory aligned for a specific frequency (per system
specification), signal levels and optimum performance.
IT IS HIGHLY RECOMMENDED THAT YOU RUN YOUR SYSTEM INTO A
DUMMY LOAD BEFORE INSTALLING TO MAKE SURE THERE ARE NO
DAMAGES CAUSED IN SHIPPING AND THE UNIT IS RUNNING PROPERLY
1. Verify that all control and RF cables are tight and properly seated in or on the
mating connector.
2. Plug in the desired audio source: analog (left and right for stereo), digital or
MPX. For mono audio use the Right XLR input.
3. With the power amplifier loaded into the antenna, cavity, alternative load, or
dummy load power up the amplifier by turning on power supply either via the
ON/OFF switch on the back of the power amplifier.
4. Verify that the power amplifier fans are all on. The power amplifier fans are
powered via DC voltage so this is an indication that the power supply is
started and running. There may be fans installed in the filter or power supply
enclosures, if applicable.
5. The internal soft start circuitry will turn the bias voltages off until the power
supply to the amplifier pallets is fully stable. The front display indicates when
the soft start is running with either a displayed message when an LCD option
is installed or via maximum attenuation when a touch screen option is
installed. Once complete, the Forward and Reflected Power, Power Supply,
and Temperature readings will appear on the display. Deviation is shown on
the FM screen.
6. Adjust RF output power on the power amplifier to about 10% of rated forward
power. The output power level is adjusted from the power amplifier’s RF
Levels screen. Then turn the carrier on, the Carrier On/Off is in the top right
corner of the touch display on all screens. If the unit contains more than one
final amplifier pallet (illustrated in your Block Diagram included in the
Quickstart package), ensure that the final pallet currents on the multiple finals
all match within 10% of each other. With multiple finals, the final pallet
currents should always match within this range under all operating conditions.
Front panel readings will vary slightly upon turn on. Steady state parameters
can be taken after approximately one hour.
