2.1 Responsibility of Manufacturer
The Manufacturer takes any kind of responsibility for and in connection with the functionality
and use of the system
– including proper use of hardware and software – according to the
relevant provisions of law. The Manufacturer takes no responsibility for damage resulting
from:
- the user having lost the device for controlling the system, or this device or his personal
data mentioned above having been stolen, thus enabling an unauthorized person to
have access to the system;
- the user having intentionally, in good faith, directly or indirectly given his personal data or
the device suitable for controlling the system to a third person.
3 Connecting the terminals and putting into operation
3.1 Under Voltage Lock Out (UVLO) function
The product is provided with built-in automatic power disconnection (Under
Voltage Lock Out) function. Depending on the product type, if the supply voltage
drops below 8.4…8.2V, the module turns off automatically and it turns back on
when the supply voltage is at least 11.2…11.4V.
The minimum supply voltage level required to turn the module on is 11.2…11.4V!
After turned on with supply voltage higher than 11.2…11.4V, the module can operate
stably even at lower supply voltage, but not lower than 8.4…8.2V.
If the module is powered from a power supply provided with a backup battery and there is
no other electrical load on the battery when charging fails (e.g. in case of a power cut), while
the battery discharges, the module turns off automatically at 8.4…8.2V voltage level.
Thereafter, if the battery is in good condition, it can regenerate and can reach the terminal
voltage of 11.2…11.4V where the module turns back on, then the battery may discharge
again below 8.4…8.2V. This may result a continuous switching on and off cycle that lasts
until the battery can no longer regenerate to the 11.2…11.4V voltage level. If this
phenomenon occurs, the battery is flat and it should be replaced.
