7. Reserve power supply circuit.
The power supply is equipped with intelligent circuits: charging and battery control circuit, whose main task
is to monitor the condition of the battery and its connections in the circuit.
If the power supply driver detects a malfunction in the battery circuit, appropriate signaling and change in the
APS FLT technical output take place.
7.1 Running the PSU from the battery.
The PSU has been equipped with two buttons on the PCB board which enable running or disconnecting
the PSU during battery-assisted operation.

Running the PSU from the battery : press the START button on the main board and hold for 1s.

Disconnecting the PSU from the battery : press the STOP button on the main board and hold for 5s.
7.2 Deep discharge battery protection UVP.
The PSU is equipped with the disconnection system and the discharged battery indication. If the voltage at
the battery terminals drops below 10V
±0.2V will turn on the beep sound and disconnect the battery in the 15
seconds.
Re-connecting the battery to the power supply occurs automatically upon the appearance of the 230V AC mains
voltage.
Battery protection ON/OFF:
Enter the PSU settings from the LCD panel by pressing the
„SET” button and select:
„PSU -> Battery protection: ON/OFF”
(see section. 6.2.3).
Caution.
Deactivating of the UVP function is not recommended since a deep discharge of the battery limits its
capability of storing energy, lowers its capacity and shortens its durability.
7.3 Battery test.
The PSU runs battery test every 5 minutes. During testing, the control unit of the PSU measures the
electrical parameters according to the implemented measuring method.
A negative result occurs when the battery circuit continuity is interrupted or if the terminal voltage drops
below 12V.
The battery test can be activated manually (see section 6.2.2) from the menu of the power supply or by
pressing the STOP button, for example to test the replaced batteries.
The PSU is protected against too frequent performing of the battery test, which could result in
undercharging. The protection involves blocking the ability to perform test for 60 seconds from the last activation.

n this case, the LCD will display the "
WAIT” message in the PSU Settings -> PSU -> Battery test menu.
Fig. 24. Temporary lock of the battery test.
Temporary lock of the battery test can be disabled by putting the Z2 jumper between J1-J2 on the power
supply board (Fig.2 [2]).
The battery test will also be automatically locked when the PSU is in the operating mode, in which the
battery test is impossible. Such condition occurs, for example, during battery assisted operation or when the power
supply is overloaded.
