4. Operation from battery
4.1 Startup from battery.
The operation time from battery depends on the capacity, charge level and load current of battery. For
example, the maximum operation time, which is not harmful for the fully charged battery 7 Ah and load
current of 2A is about 3h.
•
To start the power supply unit from the battery : press and hold Start button on the unit
board for 5 s.
•
To stop the power supply unit from the battery : press and hold STOP button on the unit
board for 2 s.The output will be disabled after about 10 s.
4.2 Disconnection of the discharged battery
The power supply unit is equipped with the function disconnecting and informing about the discharge
of the buffer battery.
During the operation from the battery, the decrease of the battery voltage to below 10 V enables the
counting of the time for the disconnection of the battery.
The battery disconnection time is set by jumpers Z3, Z4. (Tab.4)

4.3 Dynamic test of battery charge
Every 10 minutes the unit executes the battery test by lowering the input voltage and measuring the
voltage on the battery terminals. If the measured voltage is lower than ~12.2V, the failure is indicated.
The battery test can be disabled, for example, when the battery was removed from the power supply
unit.
To enable/disable the battery test : Press and hold the STOP button for 3 s during the operation from
the mains. The activation or deactivation of the battery test is indicated as follows:
•
test disabled 12 acoustic signals
• test enabled 3 acoustic signals
Note:
•
the activation/deactivation of the test is stored even after the disconnection of the unit
from the mains.
•
disabling the test will also disable signalling the faults to the battery on the AW output,
but will not disable the system protecting the battery from entire discharging
.
4.4 The limitation of the battery charging current
The unit is equipped with the function for the limitation of the battery charging current
