Inverter Functionality
The FXR inverter can be used for many applications. Some of the inverter’s operations occur
automatically. Others are conditional or must be enabled manually before they will operate.
Most of the inverter’s individual operations and functions can be programmed using the system
display. This allows customization or fine tuning of the inverter’s performance.
Before operating the inverter:
The operator needs to define the application and decide which functions will be needed.
The FXR inverter is programmed with seven AC input modes. Each mode is optimized for a
particular application. Some modes contain functions unique to that mode.
The modes are described in detail following this section. To help decide which mode will be
used, the basic points of each mode are compared in Table 2 on page 21.
Apart from the input modes, FXR inverters possess a set of common functions or operations.
These operations are described in detail beginning on page 22. Most of these items operate the
same regardless of which input mode is selected. The exceptions are noted where appropriate.
Each distinct mode, function, or operation is accompanied by a symbol representing the inverter
and that operation:
The symbols may have other features depending on the operation.
AC Input Connection
The FXR inverter has one set of input connections. Only one AC source can be physically
wired to it at any time. However, two different AC sources can be used with an external transfer
switch. It is common for backup or grid-interactive systems to use the utility grid as the primary
source, but switch to a gas- or diesel-powered generator in emergencies. The inverter can be
programmed with separate input criteria for each source.
The inverter’s two input selections can be programmed for separate input modes (see below).
The selection (
Grid
or
Gen
) can be chosen in the
AC Input and Current Limit
menu. (See
the menu tables beginning on page 66.)
NOTE
:
The input types are labeled for grid and generator due to common conventions, not
because of inverter requirements. Each selection can accept any AC source as long as it meets
the requirements of the FXR inverter and the selected input mode. If necessary, the
Gen
selection can accept grid power. The opposite is also true.
