FUNCTIONAL DESCRIPTIONS
Digital Voltmeter
The digital voltmeter shows the current operating voltage in volts. When the
applied voltage drops below 10 volts, the volt indicator will start flashing. If the
voltage falls below 5 volts, the volt indicator flashes with “0,00”.
If a voltage of more than 20 volts is applied, the voltmeter starts to flash with
“-,--”. In this case disconnect the power supply and check what causes the
overvoltage.
The digital volt indicator turns off when a stable voltage is applied for more than
a minute and will not turn on again until there is a voltage swing.
Status-LED
The two status LEDs light up as soon as the capacitor is energized and the
automatic turn-on function switches it on.
Reverse polarity protection
The capacitor has a reverse polarity protection, if “+” and “-” are reversed
during connection. An acoustic warning tone sounds. In this case disconnect
the power supply and discharge the capacitor completely until the warning tone
can no longer be heard. Then reconnect the capacitor to the power supply and
check for the correct polarity of the power connections.
