ODEL WITH STAND BY SYSTEM
The inverters from the AJ 500-12 are equipped
with a stand-by system (also available in the
models AJ 275-12/350-24/400-48 with the
option -S).
The stand-by is an energy saving system which
turns off the inverter intermittently when no
consumer is detected. In this mode the
functioning indicator (green LED 1) blinks,
showing the intermittent presence of the
voltage.
The detection threshold is set by default at 2 W.
On models from AJ 500-12 onwards it is possible
to deactivate this function or to modify the
threshold by adjusting the yellow turning knob
marked Stand-by.
Adjust the switch-on level as follows: Switch off
all loads; turn the turning knob to the right
(clockwise) until the LED is blinking, switch ON
the smallest load (i.e. mobile phone charger);
turn the turning knob slowly to the left until the
LED is lit continuously. Check that the inverter
goes back to 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 left.
The minimal detected load can be adjusted
between 1 and 20 W. In most cases this
adjustment is not necessary. This adjustment is
made with a small screw driver in the hole
marked stand-by. 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!
