Section 9: 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
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 safety interlock switch.
3. Identify which primary winding taps should be used and connected to the transformer's ac
power input (
Line
) terminals. See Table 4.1 on page 4-1 .
4. Confirm that the taps are configured correctly.
5. Remove the rear filters from the transmitter and spray them with filter coat adhesive spray
(Nautel Part # HQ59), located in the ancillary kit. Re-install the rear filters on the
transmitter.
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.
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.
CAUTION:
REMOVE AIR FILTERS BEFORE USING THE FILTER COAT ADHESIVE SPRAY. THE SPRAY
WILL CONTAMINATE THE INSIDE OF THE TRANSMITTER, CAUSE ACCELERATED DUST/
DIRT BUILDUP AND COMPROMISE CRITICAL SPACINGS FOR VOLTAGE BREAKDOWN.
