Going On-Air
IMPORTANT!
Before going on the air, if you want the safety interlocks to operate properly, the
shorting jumpers installed in “Pre-Commissioning Tasks” on page 2.9.2 , Step 4 should be removed.
1. Turn off the power using the ac disconnect switch, if one is being used, or else at the ac source.
2. Connect the transmitter's RF output to an antenna system (or verify that the current connection is
intact).
3. Turn the transmitter’s ac power back on.
4. Use the front panel UI to begin transmitter operations. For detailed instructions, refer to the
NV20LT/NV15LT Operating and Maintenance Manual.
 Set for desired power level.
 Press the front panel’s RF On pushbutton switch.
 Select the desired exciter as main, if applicable.
WARNING! If a jumper is placed between the INTLK inputs [pins 19 and 20
of the controller’s REMOTE I/O-A connector (A1J2A) or TB1-1 and 2 on the
optional remote interface PWB], safety features controlled by the external
interlocks will be disabled. A fail-safe method of alerting personnel to this
fact should be implemented. Voltages which are dangerous to life will be
present on the RF output stages and the antenna system if the transmitter
is turned on.
