Operation of the Inverter without Automatic Mode (S
tand-by Mode = OFF):
If the inverter shall be operated without automatic mode, which might be required for unproblematic operation of
consumers with very low capacity, such as battery chargers, portable radios etc., the automatic mode must be deactivated.
This can be effected in two different ways.
1.
Permanent Setting:
Set switch 3 (PowerSave) to position OFF.
2.
Setting can be selected when starting the inverter
Push the ON/OFF switch for more than 3 seconds when starting the inverter. After this time, the yellow LED
„AUTOM.“
will
stop lighting
, and the inverter is in continuous mode.
If the connected consumer is switched-off, the inverter will continue working (idle time), and it will load the
battery permanently with approx. 3.5 Watts.
Operation of the Inverter in Permanent Continuous Operation:
If the inverter shall operate in permanent continuous operation, set switch 4 (RunMode) to position "Always ON".
This switch position starts the inverter automatically as soon as it is connected to 12 V battery voltage.
The inverter will only be switched-off automatically if external 230 V supply voltage is supplied, since the unit socket will
then be supplied by the external supply voltage. After removal of the external supply voltage, the inverter starts
automatically.
During this mode the key of the display panel has no function. Operation of the inverter can be reactivated by
setting switch 4.
Connected Capacity of the Connected Consumers:
A safe operation requires, that the total of the nominal capacity rates (Watts) of the connected consumers (indication in
"VA" or "W" on the nameplate or in the technical data of the corresponding appliance) does not exceed the nominal
capacity of the inverter (300 / 600 W).
Please observe, that the real current consumption of many 230 V household appliances is higher than the value resulting
from the active power, which is indicated in "W" on the nameplate.
It is also to be considered that almost all appliances are requiring a higher capacity during the starting phase (moment of
starting) than during the normal operation. The starting capacity can be
many times higher than the continuous rating
!
When starting these appliances, the inverter can be loaded above its nominal capacity for a short-moment (refer to
technical data).
Pilot Lamps Load/Overload and Overload Protection:
The load
of the inverter is indicated by three light-emitting diodes (LED) at the control panel:
The LED
„< 50 %“
is lighting in green, if the load is approx. 10 / 20 Watts up to 50 % of the nominal capacity of the
connected appliance.
If the nominal capacity exceeds 50 %, the LED
„<100 %“
will be lighting in yellow.
If the inverter is operated with
more than
100 %
of its nominal capacity,
the red LED
„OVERLOAD“
will be lighting.
Additionally, an audible alarm will refer to the overload.
From an overload of 5 %,
the rhythm of the audible alarm will be slow
. During this operating state, the inverter will
continue working; however, a disconnection of the inverter due to overtemperature can be expected in the long
term.
From an overload of 15 %,
the rhythm of the audible alarm will be quick.
In case of this operating state, the
inverter will be disconnected within the following 10 seconds. Now, the drawn capacity should immediately be
reduced.
If the maximum duration for the overload is exceeded, the inverter will be switched-off. The green LED
„INVERTER“
will
stop lighting, the red LED
„OVERLOAD“
will be flashing, and an audible signal can be heard. After reduction of the
connected load or disconnection of unused consumers, the inverter can be restarted by pushing the ON/OFF switch.
