Figure 4-5. Root Menu
The operation of these four fields is as follows:
4.2.1.1 Status
The Status field in the Root Menu provides an indication of the status of the selected channel.
The Status fields indicate the converter’s configuration (Single, Primary, Backup) if the converter
is Online; Setup, if the converter is in setup mode; or Offline if there is a fault in the converter
which would prevent it from being placed online. The Status field also indicates under which
channel number the Frequency and Gain information is being stored.
The Root Menu will appear by default upon power-up. Prior to putting a converter online, the
correct frequency should have been selected. A properly functioning converter that has no faults
and is ready to be placed online will have the status indicated at ‘Setup.’ The structure of the
Status prompt is as follows:
{Status}{Channel No.}
SINGLE: Indicates that the converter is in a standalone
configuration and that when presented with an input
signal of the specified frequency, will generate an output
signal with the specified conversion gain.
PRIMARY: Indicates that the converter is in a switched
configuration, and that when presented with an input
signal of the specified frequency, is capable of
generating an output.
BACKUP: Indicates that the converter is in a switched
configuration, and that when presented with an input
signal of the specified frequency, is capable of
generating an output.
SETUP: Indicates that the front panel is unlocked and the
operator has free control of the Gain and Frequency
fields.
OFF LINE: The converter has experienced a fault and has placed
itself off line. Off Line Status is the same as out-of-
service. The fault will have to be cleared and/or the
failed component replaced.
The ‘Channel No.’ field of the Status prompt includes the numbers from 01 to 30 to indicate
which stored channel is being programmed or recalled with Frequency and Gain information.
