Operation

¾Fault activates the AUX output when the inverter shuts down due to an error condition (see page 37). 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.

∼This function is not triggered by Phase Loss Error, as Phase Loss Error does not shut down the inverter.

¾Gen Alert is used as a controller for an AC generator with a remote start feature, although it has limited functionality. (The generator recharges batteries using the inverter’s battery charger.) When the battery voltage falls to a low set point for a settable delay, the AUX output is activated. The AUX output is used to energize a relay. The relay contacts then operate the remote start/stop circuit on the generator. (This is illustrated in the International Series GFX Installation Manual.) The AUX output will be deactivated once the battery voltage rises to a high voltage setting for a settable delay period.

∼This function has settable voltage and time parameters.

∼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) feature 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.

¾Load Shed activates the AUX function to perform load management. When battery voltage drops below a certain level, the AUX output is activated. The AUX output energizes a normally closed (NC) relay, which is connected to non-vital loads. When the relay is energized, the loads are disengaged to conserve battery power. Load Shed will also occur when the inverter enters a high-temperature condition or when the AC output voltage drops below 210 Vac for more than three seconds. After these conditions have cleared, there is a three-minute fixed delay before the AUX output is deactivated.

∼This function has a settable DC voltage parameter.

¾Remote allows the AUX output to be activated in response to manual or automatic commands external to the inverter, such as the system display’s AGS function. It is strongly recommended to select Remote when the AUX output is controlled by AGS or similar functions. This will prevent software conflicts.

Note that even if this menu is set to off, the AUX output may still be triggered by an external function such as AGS (see page 30).
