External 10 MHz
You can configure the VX150 to VX2 to accept an external 10 MHz input using the AUI or using the
front panel UI (see
FM Polarity, on page 2.2.139 ).
This setting allows the user to mask the associated 10 MHz alarm from appearing in the Event History
page if it isn't being used. If an external 10 MHz source is being used, an alarm will be activated on the
Event History page should the external signal be lost.
NOTE
:
The exciter will be monitoring for the presence of an external 10 MHz signal all the time, even if
the set to "disabled" and will not take any action. If the Pilot Sync option is enabled in the active
preset, then the state of the external 10 MHz enable is ignored and the exciter will continuously
regulate the RF carrier signal based on the external 1PPS signal.
To enable the External 10 MHz input on the AUI’s External 10 MHz page (see Figure 2.2.30 ), slide the
External 10 MHz Enable/Disable switch to the right and click Save
.
