The control box feature a range of built-in safety devices, increased current cut-off, EAS (Electronic
Arc Suppression), and other options such as battery backup, earth outlet, wet alarm etc.
CB12 with battery backup
The CB12 with battery backup has an acoustic alarm, which sounds when the batteries are low,
approx. 17 - 18V. To charge the batteries on a CB12 with internal batteries, just connect the CB12 to
mains. With external batteries, connect the external batteries to an external charger.
External battery charger
If anything other than a LINAK
®
charger is used, it must conform to the following specifications:
Charging voltage: 27.6 V DC ± 2%
Charging current: < 300 mA.
Warning

Microprocessor
All control boxes with a microprocessor must be initialized before start-up. A description of the initialization procedure can be obtained from your
LINAK dealer. If an actuator is replaced, the microprocessor always has to be initialized before use (actuators with reed/hall). If re-programmed,
please ensure that the correct software is used.
External battery charger
If anything other than a LINAK
®
charger is used, it must conform to the following specifications: Charging voltage: 28.0 VDC ± 2 %
Charging current: < 300 mA.
For recommendations on maintenance and storage of the BA20 battery packs,
please refer to chapter 5.
