E.7.1 The Inverter
The Inverter section of the unit produces a high quality Sinewave output, the
quality of this output is compatible with any appliance, Thanks to the generous
dimensioning of the unit , you can operate appliances requiring higher power
than the nominal power of the unit for a short time. The unit provide up to
3-times the nominal power to start motors etc.
E.7.2 Power saving function (
Fn02)
In order to avoid unnecessary discharge of the battery, the inverter switches OFF
automatically if no AC power is being used. The unit switches ON
automatically again if an AC load is switched ON. The AC Out LED blinks if the
inverter is in “Power Saving-Mode”
.
If the “Power Saving-Mode” is not wanted, set the Fn02 "DISABLE" function.
This will keep the unit running continuously, but will also discharge your
batteries quicker.
E.7.3 Overload
If the unit is overloaded for too long or too heavily, it switches off. The
“Multi-display” will show “
” and the “RUN/STOP” LED will RED Blink. After
approximately 10 seconds the Inverter switches on automatically. If the unit is
overloaded four times in quick succession, then it no longer switches back on
automatically. The “RUN/STOP” LED remains lit, and the multi-display show “
”.
Press the push button 1(PB1) ”RUN/STOP” in order to switch the unit back ON.
E.7.4 Overheating (Over Temp)
If the Inverter has been overload for a long time or it has been working in a high
ambient temperature, it will switch OFF. The “Multi-display” will show “
” and
the “RUN/STOP”LED RED blinks. After cooling down, the inverter switches back on
automatically. One minute before the inverter switches off due to high temperature
a buzzer will be heard. If the Auxiliary Contact has been programmed for “Over
Temp” then the contact will be active when the buzzer sounds. This could be used
for example to start an emergency back up generator, creating a no break energy
supply.
