In a system that is providing backup power, the System Mode will be in Inverter mode (AC line has
failed, or not within acceptable limits).
Figure 53: System Mode
When the System Mode shows Error, then the controller is unable to communicate with the FXM HP
module. If this value persists for more then a minute or so, it may indicate that the FXM HP is not config -
ured or working properly.
The FXM HP can be in one of the following modes:
Table 11: FXM HP Operating Mode
Mode Description
Standby The unit is switched on and waiting for the line power to qualify or
resolution of pending faults/alarms.
Retransfer The unit is transferring to Line mode from the following modes:
Inverter, Shutdown or Standby.
Boost1 and Boost2 The unit transformer is increasing output line voltage due to the input
voltage being lower than specification.
Line The unit is switched on and line power is provided to the load.
Buck1 and Buck2 The unit transformer is decreasing output line voltage due to the input
voltage being higher than specification.
Inverter The unit is providing backup battery power to the load.
Bypass The unit is feeding input directly to the load without providing any
features such as automatic voltage regulation or a backup power.
Shutdown The output is turned off via a user input or via web/LCD interface, and
the power to the load is disconnected. For safety reasons, the AC Input
Breaker and DC Breaker should be opened before servicing the unit.
Fault The unit has a recoverable fault. AC and DC outputs are off until the
fault is cleared.
Permanent Failure The unit has a permanent failure. Example: backfeed relay failure.
Battery Test The unit is running a Battery Test. The unit is providing battery power
to the load.
