Operation
42 900-0167-01-01 Rev A
 Settable Gen Alert parameters include:
 Low and high DC voltage
 On and off delay
Gen Alert control logic is located in the inverter. It has the advantage of functioning when the
system display is removed. However, it may not completely charge the batteries and does not
have all the advantages of the Advanced Generator Start (AGS) function that is found in the
system display. For many users, the AGS function may prove more useful than Gen Alert.
Gen Alert, however, could be used as a literal “Generator Alert”, a signal to the user to manually
start a generator.

Fault
activates the
A
UX
output when the inverter shuts down due to an error condition. (See page
52). It can activate a light or alarm to show that the inverter has failed. With the appropriate devices,
it could send an alarm signal through a radio, pager, or telephone dialer.
 This function does not have settable parameters.

Vent Fan
activates the
A
UX
output in response to a high DC (battery) voltage set point. It can run a
small fan to ventilate the battery compartment to eliminate gases that result from battery charging.
(This is illustrated in the FXR Series Inverter/Charger Installation Manual.) When the voltage falls
below this set point for a settable delay period, the
A
UX
output turns off. This is the default selection.
 Settable parameters include:
 High DC voltage
 Off delay

Cool Fan
activates the
A
UX
output when the inverter reaches a high internal temperature. It is
intended to trigger a small external fan for additional cooling. See the
Warning Troubleshooting
table on page 53 for a description of the fan criteria.
 This function does not have settable parameters.

DC Divert
activates the
A
UX
output to divert (or “dump”) excess renewable energy to a DC load, such
as a resistor, a heater, or a fuel cell. This prevents overcharging of the batteries. This function can
serve as rough charge regulation for an external charging source.
 When battery voltage rises above a settable high voltage level, the AUX output is activated after a
settable delay. The A
UX output controls a larger, external relay. When energized, the relay allows
current to flow from the batteries to a dedicated DC load. (This is illustrated in the FXR Series
Inverter/Charger Installation Manual.) The resistor or load must be sized to dissipate all of the
energy from the renewable source if necessary. Diversion will turn off following a delay when a
low DC voltage setting is reached.
 Settable parameters include:
 Low and high DC voltage
 On and off delay
 GT Limits activates the AUX output as an alert that the utility grid does not meet Grid Interface
Protection parameters for the grid-interactive function. (See page 17.) It can activate a light or
alarm to show that the grid-interactive function has shut down and that there may be problems with
the grid. The A
UX output will cycle on and off if grid parameters are met and the reconnection timer
is counting down.
 This function does not have settable parameters other than those of the Grid Interface
Protection menu.

Source Status
activates the
A
UX
output whenever the inverter accepts an AC source. It can activate
a light or alarm to show that the utility grid is present or that a generator has started. Alternately, it
could be used to show that the source has disconnected.
 This function does not have settable parameters.
