Example – Active Low:
Set
Close Volts
below
Open Volts
voltage. If the
Close Volts
voltage is set
at 24.0 VDC and the
Open Volts
voltage is set at 29.0 VDC, the relay closes when the battery
voltage drops to 24.0 VDC and opens when the battery voltage rises to 29.0 VDC. Use this
configuration to control a battery exhaust fan, or as a simple PV charge controller.
Example – Active High:
Set Close Volts above the Open Volts voltage. If the
Open Volts
voltage
is set at 24.0 VDC and the
Close Volts
voltage is set at 29.0 VDC, the relay opens when the
battery voltage drops to 24.0 VDC and closes when the battery voltage rises to 29.0 VDC. Use
this configuration to control a low voltage disconnect circuit for a DC load.

Open Delay
– Delays the opening of the Aux Relay contact once the battery voltage trip
point has been reached. This sets a hysteresis so the Aux Relay does not cycle unnecessarily.
◊
Close Delay
– Delays the close of the Aux Relay contact once the battery voltage trip
point has been reached. This sets a hysteresis so the Aux Relay does not cycle unnecessarily.
Default settings:
Open & Close Delay = 10 secs
Range:
OPen & Close Delay = 0-127 secs,
then
1-127 mins
Info:
The
Open/Close Volts
and
Open/Close Delay
settings are only available if the
Auto
VDC
or
Auto VDC (BTS Comp)
options have been selected from the
CTRL:
04 ARTR Aux
Relay
menu.
Example:
The Aux Relay set to
Auto VDC
. The
Open Volts
= 29.0 VDC and the
Close Volts
= 24.0
VDC, and the
Open Delay
and
Close Delay
settings are set to 10 seconds.
When the battery voltage reaches 24.0 VDC, after a 10-second delay the Aux Relay closes and
the LED illuminates. When the battery voltage reaches 29.0 VDC, after a 10-second delay the Aux
Relay opens and the Aux Relay LED indicator turns off.

ARTR Relay SOC:
The ARTR Aux Relay becomes a battery SOC-controlled relay when
Auto SOC
is selected from the
CTRL/04 ARTR Aux Relay
menu. It can be programmed to open
or close on the battery’s State of Charge using the following settings.
Note:
Requires a ME-BMK Battery monitor to provide SOC values to the inverter. If BMK not
installed, “
No BMK Present
” displays.
◊
Open
– The battery SOC trip point at which the Aux Relay contacts open. This setting can
be below or above the
Close
setting, depending on if you want the Aux Relay to be active low
(i.e., set
Open
below
Close
) or active high (i.e., set
Open
above
Close
).
◊
Close
– The battery SOC trip point at which the Aux Relay contacts close. This setting can
be below or above the
Open
SOC setting, depending on if you want the ARTR Aux Relay to be
active low (i.e., set
Open
below
Close
) or active high (i.e., set
Open
above
Close
).
Default settings:
Open = 50%; Close SOC = 100%
Range:
Open and Close = 20-100%
Info:
The
METER: 05 BMK Meters/05A BMK SOC
meter must have a valid SOC number
for the ARTR Relay to determine when to start and stop based on the battery SOC.
Under the
METER/05 BMK Meters/05A BMK SOC
menu,
Think’n
,
No Comm
, or any
BMK fault (i.e.,
Factory Fault
,
Power-up Fault
, or
Unknown Fault ##
) are not valid SOC
numbers.

Max System Charge Amps:
This menu setting is the maximum current allowed to
charge the batteries during Bulk, Absorption, Float, and Equalize charging; and is provided to
limit the charge amps.
Note:
If “CC/CV Controlled” displays on this menu’s screen, you will not be able to adjust the
settings as “CC/CV” has been selected as the battery type from the 03C Battery Type menu.
Default setting:
Disabled
Range:
Disabled, 20-2500ADC
Info:
If the BMK (Battery Monitor Kit) is connected, the DC amps value determined by
the BMK (under
METER: 05C DC Amps-BMK
) will be used by the
Max Chg Amps
setting
instead of the inverter’s DC calculated current (shown under
METER: 01B Inv/Chg DC
Amps
)—as it is more accurate (+/ – .1 ADC).
