Auxiliary Output

The A

(Auxiliary) is a secondary control circuit — essentially, a small power supply that provides a

12 Vdc output current (up to 250 milliamps or 3 watts) to an isolated load. It can be ON

with 12 Vdc

available at the output, or OFF

with 0 Vdc at the output. It can also be set to AUTO. In this setting, the A

output turns on or off according to specific criteria such as high or low voltage. In some cases, such as

the PV Trigger, Night Light, or Diversion: Relay applications, the polarity of the output can be reversed

so that the behavior is reversed. These selections use the A

OLARITY

setting (H

IGH

or L

The A

output can control devices such as cooling fans, vent fans, load diversion, fault alarms, and

automatic generator control. See page 20 for examples of applications.

can be selected or operate at a time (even if other modes have criteria preset).

See Figure 43, page 49, for an auxiliary setup wiring diagram example.

NOTE: Diversion: Relay and Diversion: Solid St can be used for AC coupling applications.

The ten options appear in the following order when the wheel is drawn clockwise. The Vent Fan option

appears first if the charge controller is set at factory default values; otherwise, it will tend to display the

last option selected.

Function:

When the Enable Voltage set point is exceeded,

the A

output will activate for at least 15 seconds.

If the set point continues to be exceeded, the output

will remain active until the voltage falls below the

set point.

Once the voltage decreases below the set point, the

output will remain active for another 15 seconds.

It will then deactivate.

Purpose:

This mode is intended to operate a vent fan to

ventilate gas from a battery enclosure.
