B 5 Battery
The battery can be charged by the battery charger, which is placed in the switchbox.
( 1 ) Mainswitch
( 2 ) Plug of the battery charger
( 3 ) LED lamp
- Turn the main switch (1) off.
- Insert the plug of the charger (2) in the socket,
the voltage of the mains should be between 110 ... 240V.
- The LED lamp changes during the load cycle from red (empty battery) to yellow (almost fully charged battery)
to green (fully charged battery).
In approx. 6 hours loading time an empty battery (13) is again fully charged (green LED lamp is lighted).
A full battery load is sufficient for placing a minimum of 120 elements (approx. 1 full day of operation).
When the green LED lamp is lighted, the battery charger will automatically switch to maintenance loading. The
connector can therefore remain in the electric socket without any danger of overloading the battery.
In case of a charged battery the volt meter on the cabinet indicates between 12 ... 14 Volt, when the vacuum
pump runs, it will fall back with approx. 1V.
If the meter falls back significantly to back with 2 or more Volt during additional pumping, this means that the
battery is discharged.
In case of a discharged battery the vacuum pump will also run slower, due to which it will not achieve the set
switch off vacuum level and the vacuum pump will run constantly.
If the voltage of the battery decreases below the 11V, the electronic vacuum switch will also turn off, because
of this, the vacuum pump will run constantly, the red lamp will light up and the acoustic alarm signal will
sound.
The battery will last approx. 3 to 5 years, because the capacity will decrease after time, we advise to renew the
battery every 3 years as a precaution.
It improves the life time of the battery when it is stored in a charged state.
We recommend that, even if you don’t need the device the next day, to charge immediately after use.
Interim charging the battery has no negative impact on it’s capacity (no memory effect).
