Auxiliary Relay (AUX Modes, Radian-class only)
The Auxiliary Relay controls the functionality of a Radian-class inverter’s Auxiliary (AUX) relay contacts.
The inverter’s AUX relay provides a set of “dry” contacts which can be used as a switch to control external
loads. Typical loads include signaling a generator to start, sending a fault alarm signal, or running a small
fan to cool the inverter. See the inverter Installation Manual for more information on hooking up the AUX
terminals.
NOTE: The Radian inverter is equipped with two sets of AUX terminals: Auxiliary Output and Auxiliary
Relay, each with its own menu. These menus control the output and functionality of the AUX relay.
Figure 112 Auxiliary Output
Auxiliary modes include the following:
 Load Shed can perform load management. 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 operate a relay, 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. See the Operator’s Manual for other conditions when this function may be deactivated.
This function has settable DC voltage and time parameters.
Figure 113 Load Shed
Set Point:
 ON: Batt – Sets the high-voltage level at which the
Load Shed function activates the AUX output.

Delay – Sets the delay time after the ON: Batt setting is
reached before the AUX output is activated.
 OFF: Batt – Sets the low-voltage level at which the
Load Shed function deactivates the AUX output.
 Delay – Sets the delay time after the OFF: Batt setting is
reached before the AUX output is deactivated.
Set Points:
 Status – The AUX relay status is controlled by the
, , and soft keys.
~ activates the Auxiliary Relay immediately. It will
display the message Manual On and remain continuously
active until is selected.
~ activates the Auxiliary Relay by automatic criteria,
according to the option selected in Aux Mode. When
activated, it displays the message
Auto On; otherwise it
displays Auto Off.
~ deactivates the Auxiliary Relay and prevents any of
the inverter’s automatic AUX options from working. When
is selected, it will display
Manual Off. Note that even if
the AUX relay is set to Off, it may still be activated by an
external option not based in the inverter, such as AGS. (See
page 115.) If this soft key is pressed, the screen will display
Manual Off.
 Aux Mode – Selects one of nine functions with automatic criteria.
(These functions are described briefly in the next section and in
greater detail in the inverter Operator’s Manual.)
Aux Modes:
 Load Shed
 Gen Alert
 Fault
 Vent Fan
 Cool Fan
 DC Divert
 IEEE
 Source Status
 AC Divert
