Aux Screens
The AUX (Auxiliary) is a secondary control circuit — essentially, a small power supply that
provides a 12 Vdc output current (up to 200 milliamps / 2.4 watts) to an isolated load. It is either
ON (Active High) with 12 Vdc available at the output or OFF (Active Low) with 0 Vdc at the
output. It can also be set to AUTO, so that it activates when certain criteria are met.
The AUX output can respond to specific criteria and control cooling fans, vent fans, load
diversion, fault alarms, and automatic generator control. In some cases, such as the PV
Trigger, Night Light, or Diversion:Relay applications, the polarity of the output can be
reversed so that a lack of power activates the output. This function is controlled through the
Aux Polarity screen in the ADVANCED MENU. (See page 56.)
NOTE: Diversion:Relay and Diversion:Solid St can be used for AC coupling applications.
The A
UX output can also be controlled externally through the system display. See the literature
for the system display (if used) for details.

Only one
AUX MODE
can operate at a time (even if other modes have been preset).

See Figure 27, page 42, for an auxiliary setup wiring diagram example.

Mode Name Function/Purpose Set Points Aux Polarity
Vent Fan
Function:
When the threshold voltage set point is exceeded,
the A
UX output will change state for at least 15
seconds. If the set point continues to be
exceeded, the output will remain in that state until
the voltage falls below the set point.
Once the voltage decreases below the threshold
voltage, the AUX output will remain in that state for
another 15 seconds. It will then deactivate.
Purpose:
This mode is intended to operate a vent fan for a
battery enclosure to ventilate hydrogen gas from
the enclosure.

PV Trigger
Function:
When the threshold voltage set point is exceeded,
the A
UX output will activate.
When the threshold voltage decreases below the
voltage set point, the output will remain active for
the duration of the hold time set by the user.
Purpose:
This mode is intended to operate an alarm, or
relay that disconnects the PV array, when
PV input exceeds the threshold voltage set by the
user. The mode deactivates the alarm or
PV disconnect after the time set point has
been reached.
NOTE: Do not exceed 150 Vdc or the FLEXmax
could be damaged.
