losses and cause malfunction of the
inverter.
Once the inverter is connected to the
batteries, a 230 V voltage is present in
the outlet of the inverter.

Control and indicators
Control switch on/off
There is a switch on the inverter to
activate or deactivate it. Use this function
to save the energy of the batteries when
you are not using the inverter.
Green indicator
A green light on the inverter indicates its
function mode:
Illuminated: a 230 V voltage is present in
the outlet, the inverter is on.
Blinking:
_ _ _ : No load (stand-by)
__ __ __ : the 230 V voltage has been
cut due to an alarm; the inverter will
resume function when the failure has
disappeared (see the failure table).
Off: the 230 V voltage is NOT present in
the outlet, the inverter is off.
Acoustic indicator
The AJ inverter has an acoustic indicator
for the following instances:
Intermittent beep: there is a failure in the
inverter and the outlet voltage will be
interrupted.
Possible failures:
Overheat: the acoustic indicator beeps 3
ºC before cutting the tension. If the
temperature reaches its normal level,
the voltage in
interrupted.
Low battery voltage: the indicator beeps
for a minute before the interruption. If
the voltage of the battery rises, the
outlet voltage is not interrupted.
the outlet is not
AJ V2.1
Continuous beep for two seconds: you
have pressed the ON/OFF switch to
restart the inverter. The tension in the
outlet will be immediately present after
the acoustic signal.

Model with stand-by system

The inverters from the AJ 500-12 are
equipped with a stand-by system which
is in function when no load is
connected. In that situation the inverter
is in low power consumption mode.
The output tension is not continuously
present and the LED is blinking as long
as no load is detected.
The minimal load detected can be
adjusted between 1 and 20 W. In most
cases this adjustment
necessary. This adjustment is made
with a small screw driver in the hole
marked stand-by. This adjustment is
made with a small screw driver in the
hole marked stand-by. Adjusting the
switching-on level is as follows: Switch
off all consuming devices; turn the
Turning Knob to the Left (counter-
clockwise)until the LED is blinking,
switch ON the smallest consuming
device (i.e. Mobile phone charger); turn
the Turning Knob slowly to the right
until LED is lit continuously. Check that
the inverter will go back in stand-by
mode when you remove the load. If
not, this means that the load is too
small to be detected.
If the stand-by is not required, turn the
Knob fully to the right.
In the full counter clockwise position,
the sensibility is minimal (20 W). Do
not push on the screw driver.
NOTE: in this mode the output voltage
is intermittently present at the output
