Table 6 AUX Mode Functions
Mode Name Function/Purpose Set Points Aux Polarity
Error Output
Function:
This mode responds to two emergency
conditions: low battery or failure to charge. Low
battery is defined by the
Low Battery Voltage
set point. Failure to charge means the PV has
not exceeded the battery voltage by 3 Vdc or
more for 26 consecutive hours. Either case may
mean an array problem.
This mode is Active Low only. The AUX output is
normally active. When either condition is met,
the AUX output will deactivate.
Purpose:
This mode is useful for monitoring remote sites.
It indicates when the controller has not charged
the batteries for 26 hours or more or if the
voltage remains too low for other reasons.
Deactivation is intended to operate a remote
alarm. It can send a signal through a modem
to alert a computer of the problem.

Low Battery
Voltage Active Low only. Deactivates
the output when the voltage
drops below the set point for a
set amount of time.
Night Light
Function:
When the battery voltage drops below the
Threshold voltage set point for the Hysteresis
Time , the AUX output changes states and
remains in that state for the ON Time setting.
Purpose:
This mode is intended to illuminate a
user-provided, low wattage light for as long as
the charge controller remains in
Sleep mode or
for the ON time set by the user.

Active High : Activates for a
set amount of time when the
voltage drops below the set
point for a set amount of time.
Active Low: Activates for a
set amount of time when the
voltage exceeds the set point
for a set amount of time.
Deactivates when the voltage
drops below the set point.
Float
Function:
When the FLEXmax Extreme is in the Float stage,
the output activates.
Purpose:
This mode is intended to operate a device such
as a “battery full” indicator when the FLEXmax
Extreme is in the Float stage of battery charging.
