IV— TRANSMITTER TURN ON PROCEDURE
Before applying AC Power to the transmitter for initial turn on and check out, the installation should
be approved by a qualied broadcast engineer. The turn on procedure that follows is recommended by
Pineapple Technology, Inc. engineering staff:
1. Check transmitter load or antenna for proper installation and connection to the transmitter.
2. Open the transmitter and inspect all cables and wires for loose connections or broken wires in the
rack assembly.
3. Check for damage to the equipment mounted in the rack.
4. Check all AC breakers and on/off switches to ensure that all are OFF.
5. TURN ON THE MAIN AC BREAKER LOCATED IN THE SUB-PANEL WHERE THE AC
POWER CORD WAS CONNECTED.
6. TURN ON THE MAIN AC BREAKER LOCATED ON THE ACDIS3 POWER DISTRIBUTION
PANEL LOCATED ON THE FRONT OF THE TRANSMITTER. A GREEN LIGHT SHOULD
COME ONE INDICATING POWER IS ON.
7. TURN ON THE AC SWITCH LOCATED ON THE FRONT OF THE ADP500. THE INDICATING
LIGHTS SHOULD BE ON AND READY FOR OPERATION
8. TURN ON THE AUX BREAKER LOCATED ON THE ACDIS3 FRONT PANEL. THE PA FANS
AND THE RACK EXHAUST FANS SHOULD COME ON.
9. TURN ON THE POWER SUPPLY BREAKERS LOCATED ON THE FRONT OF THE ACDIS3.
CHECK THE RR6000 POWER MODULES — six (6) EACH — TO SEE IF THE GREEN LIGHTS
ARE INDICATING NORMAL OPERATION.
10. USING THE ADP500 & PAS10 CHECK THE IDLING CURRENTS ON EACH PA TO ENSURE
THAT THE CURRENTS ARE IN THE CORRECT RANGE. TYPICAL RANGE IS 1.5 TO 2.5
AMPS. SEE ADP500 OPERATING SECTION FOR DETAILS.
11. TURN ON THE DRV100 DRIVER AMPLIFIER — THE GREEN LIGHT SHOULD COME ON.
NOTICE: The Modulator/Upconverter has been set at the factory so that the output power indication
on the ADP500 will show 100% or 3 KW p-sync power level. It is important to read the instruction
manual supplied with the modulator to locate key adjustment devices on the front panel. The output
level adjustment will be necessary for the next step in the turn on procedure.
12. Locate the level adjustment on the modulator/upconverter and turn the level down to minimum
or CCW.
13. Turn on the power switch located on the modulator rear panel.
