Turning on the transmitter
1. Switch on the ac power at the service entrance to turn on the transmitter.

Transmitter
Status
page of the AUI. See the NX400 Operations & Maintenance Manual or the NX400
Troubleshooting Manual for detailed information.
NOTE
: It is normal to see an "
External Inhibit Active
" alarm from each exciter as well as an
"

3. Check the output of the +5, +15 and -15 V power supplies on the AUI (click

+/- 10% of its nominal voltage.
4. Check the ac sample voltage on the AUI (click
Meters
, then select
Rack 1
and then select AC
Sample). It should be between 310 V and 335 V. If not, change the transformer tap setting
(see Section 4, “Connecting transformer taps/load wiring” ). If the ac sample voltage is too
high, you will need to increase the tap voltage. If the ac sample voltage is too low, you will
need to decrease the tap voltage.

field, enter 40 kW and press

.
• In the
Transmitter
block in the AUI’s top banner, press the bar that contains the active
preset name and the drop-down arrow. The

window will appear, which
contains a list of all preset options. Select the “Analog” preset and press
Activate

enable the preset as the transmitter’s active preset.
