LIST OF AUX FUNCTIONS
• Cool Fan activates the standard TurboFan which cools the FX during an over temperature condition.
• Divert DC and Divert AC allows the AUX to divert excess renewable energy to a DC or AC load,
respectively. This allows control of energy sources such as wind turbines or hydro-generators. When
using Divert AC, the AUX output will shut off if the inverter is overloaded.
• AC Drop is activated when an AC power source disconnects from an FX. An indicator, such as an
alarm, connected to the AUX warns a user that AC power is no longer available.
• Vent Fan provides 0.7 amps to run a 12VDC fan for removing hydrogen from the battery compart-
ment. Vent Fan can operate automatically when the VENTFAN ON voltage set point is exceeded or it
can operate intermittently by adjusting the VENTFAN OFF PERIOD.
• In Fault mode, the AUX can send an alarm signal via radio, pager, or telephone device when the FX
enters into an error condition. Fault mode can also be used to log error conditions by triggering an
event recording device.
• GenAlert, through a 12VDC relay, will tell the system to start a two-wire type generator when the
battery voltage falls below a certain set point. GenAlert can be adjusted according to the shortfall-
battery voltage, the amount of time spent at this voltage, the recharged voltage and amount of time
at this voltage before GenAlert is de-energized.
• Load Shed energizes the AUX the reduce the load demand on the batteries and the inverter func-
tion, thus acting as a load management system.
• Setting the AUX to Remote allows a message sent through the serial Port on the MATE to switch the
AUX on and off .
• Note that using Advanced Generator Start (AGS) overrides any programmed AUX function.
Adjustable AUX OUTPUT FUNCTIONS
There are four AUX functions whose settings can be adjusted by the user:
Diversion
Vent Fan
