Section 11: Commissioning tasks
The transmitter contains solid-state devices that may be damaged if subjected to excessive heat or
high-voltage transients. Ensure that circuits are not overdriven or disconnected from their loads while
turned on.
The transmitter was precisely calibrated and tested during manufacturing. Do not change any
adjustments other than those specified
Pre-commissioning tasks
Ac power source
1. Confirm the ac power source's nominal, loaded, phase-to-phase, rms voltage.
2. Ensure that ac power source is switched off at the service entrance.
3. Identify which primary winding taps should be used and connected to the transformer's ac
power input (
Line
) terminals. See Table 3.1 on page 3-2 .
4. Confirm that the taps are configured correctly.
WARNING: Before applying ac power and turning on the transmitter,
you must customize some circuits to the station's power source and
operating requirements. Do not perform this pre-commissioning
unless you are a station engineer or a competent electronics
technician.
Note: This procedure refers to the RF synthesizer and PDM interphase driver PWBs.
These printed wiring boards are located on the exciter panel.
WARNING: If you do not observe this precaution, you could be
seriously injured or killed by the voltages on the circuit breaker and
the transformer terminals.
