Auxiliary Terminals
The Radian inverter has two sets of terminals which can respond to different criteria and control many
operations. The 12V AUX terminals provide a 12 Vdc output that can deliver up to 0.7 Adc to control
external loads. The RELAY AUX terminals are “dry” relay contacts rated up to 10 amps (at 250 Vac or 30
Vdc). Each set of terminals has its own set of programmed criteria. Each has identical options
available. (When the options described below refer generically to the “AUX output”, it can mean
either set of terminals.)
Each AUX output has three states: continuous
Off, continuous On, and Auto, which allows that output
to be activated using the automatic auxiliary functions. (All functions are defaulted to
Auto.) These
items are based in the Radian and accessed using the system display. The system display and other
devices also have programming, such as AGS, that can control the AUX outputs. To avoid conflicts,
the output should be turned
Off when the AGS function is active. (See page 45.)
For the Radian automatic functions, typical applications include signaling a generator to start, sending
a fault alarm signal, or running a small fan to ventilate the batteries. When considering these
applications, plan for both connection requirements and programming with the system display.
The AUX terminals have a series of set points which are used by various functions. Both sets of
terminals have the same options available, but they are programmed independently. Not all set
points are used by all functions. Each AUX mode description below will detail the set points that are
used for that function.
∼ Low DC voltage settings
∼ High DC voltage settings
∼ On delay settings, in increments of 0.1 minutes
∼ Off delay settings, in increments of 0.1 minutes
These settings are not temperature compensated. Compensation is only used for inverter battery charging.
There are nine functions, each geared toward a different application. (The 12V AUX and RELAY AUX
outputs are defaulted to different selections.) These functions are summarized in Table 5 on page 44.
Load Shed can perform load management. It is intended to turn off designated loads during low battery
periods to conserve remaining battery power.
When battery voltage rises above a settable high voltage level, the AUX output is activated after a
settable delay. The AUX output is used to energize a larger external relay (normally open) which is
connected to non-vital loads. The AUX output will be deactivated once the battery voltage falls below a
low voltage setting for a settable delay period.

Load Shed will also turn off when the inverter enters a high-temperature condition or when the AC
