Pre-Commissioning Tasks
1. Terminate the transmitter's RF output into a precision, 50

, resistive dummy load that is
adequately rated for the maximum expected total power output.
2. Verify all program inputs are connected to the back of transmitter.
3. Ensure the external interlock is closed. Nautel ships the VX transmitter with an external interlock
mating connector that has a short circuit between the two contacts.
NOTE
: A mating connector (Nautel part # JR52) is supplied in the Spares kit to facilitate this connection.
It is intended to plug directly into the INTLK connector on the rear panel of the transmitter.
WARNING! If a jumper is placed between the INTLK inputs on the rear
panel of the transmitter, 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.
