Initial Power-Up Procedures - Crown FM2000A User Manual

3.1 Initial Power-up Procedures

These steps summarize the operating procedures you should use for the initial
operation of the power amplifier and power supply of the FM2000A.
1. Ensure that the external remote control unit is properly connected (See
Section 2.6 and the pin-out description table on page 2–8 for proper pin
configuration). If not using a remote control unit, pin 7 must be tied to
ground pin 6.
2. Connect Antenna.
3. If using an external remote control, enable the power supply via the remote
I/O connector.
4. Turn on (set to up) the AC input circuit breaker located on the rear panel of
the power supply (do not turn on the front panel power switch yet).

5. Turn on the exciter (a Crown FM100 or equivalent) and adjust its RF power
output level until the In Reference (In Ref) voltage, as indicated on the PA2000
front panel Digital Multimeter, is between 0.8 and 1.2 volts. This is not a drive
dependent amplifier; therefore drive must be at a constant level regardless of
main output power.
