Introduction
Technical characteristics
The voltage inverter has some technical charac-
teristics, in order to be protected and / or the
connected appliances.
Warning- and Protection display
In general errors are recognisable as follows:
- Red LED-display
1
- Peep- or butting tone
- Protection code in the LED-display
9
Overvoltage protection:
If the input voltage is above 15,5 V (+/– 0,5 V), a
buzzing sounds, the red LED-Display
1
lights
up, and HiVi is displayed on the LED-display
9
.
The voltage converter stops converting and the
external appliance will be switched off. If the
voltage drops below 14,5 V (+/– 0,5 V), the volt-
age converter starts the normal operation again.
Undervoltage protection (Battery display
function, battery protection):
If the input voltage is under 10,5 V (+/– 0,5 V), a
beep tone sounds, the red LED-display
1
lights up.
If the input voltage is under 10,0 V (+/– 0,5 V), a
buzzing tone sounds, the red LED-display
1
lights up and LoVi is displayed on the LED-dis-
play
9
.
The voltage converter stops converting and the
external appliance will be switched off.
If the voltage climbs above 12 V (+/– 0,5 V), the
voltage converter starts the normal operation
again.
Short circuit protection:
If the connected appliance causes a short circuit,
a buzzing tone sounds. The red LED-display
1
lights up and ShCt is indicated on the LED-
display
9
.
Overheating protection:
If the temperature inside the device is over 60 °C,
a beep sounds, the red LED-display
1
lights up.
If the temperature inside the device is over 68 °C,
a buzzing tone sounds, the red LED-display
1
lights up.
The voltage converter stops the converting, and
the external device is switched off.
If the temperature sinks below 50 °C, press the
key ON/OFF/MODE
3
for approx. 3 seconds to
re-start the voltage converter again.
Overload protection:
If the load is below the minimum a beep tones
and the red LED-display
1
lights up.
If the load exceeds the maximum a buzzing tone
sounds and the red LED-display
1
lights up.
In addition OvPr is indicated in the LED-display
9
.
The voltage converter stops converting and the
external appliance is switched off.
