Outback Power Systems 80 AUX Mode and Its Functions, Night Light Output Off, Exit Next SET Mode

The second line indicates the present mode for the Aux Output. When this line blinks, it indicates a pending AUX Mode.

When the preferred mode is displayed, press the <SET> soft key to select it.

This arrow indicates AUX Polarity applies to this function allowing the user to reverse the conditions that activate this function.

8. AUX Mode and Its Functions

The AUX is a secondary control circuit—essentially, a small power supply that provides a 12VDC (up to 200 milliamps) output current. It is either active (12VDC on) or inactive (0VDC). Most AUX modes or functions are designed for specialized applications and are infrequently used.

• To access the AUX MODE from the MAIN Menu, press the < > soft key until the arrow is in front of

the Aux selection (see next page).Charger GAux

•A 200 milliamps or less, 12VDC/2.4W device can be wired directly to the AUX terminal; higher output DC loads require a 12VDC coil relay—also rated up to 200 milliamps or less for the DC coil—which itself is connected to the AUX output. An internal, re-settable Positive Temperature Co-efficient (PTC) fuse protects the AUX internal components from overcurrent or a short circuit.

•For certain AUX control applications the use of a solid state relay is preferred. This is particularly

beneficial with applications such as the Diversion mode where fast switching (often called PWM control) allows a more constant battery voltage to be maintained. Both DC and AC load switching solid state relays are widely available from many sources. Eurotherm and Power-IO are two suggested solid state relay manufacturers.

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

•See Figure 5, page 36, for an AUX set-up wiring diagram example.

In this Menu, On and Off indicators show the present state of the Aux terminals. Pressing the <MODE> soft key changes the outputs value (On, Off, or Auto)

On indicates the Aux Output is in an active state; Off indicates an inactive state.
