4. Connect the receivers’ cables to the +OUT1- i +OUT2 connectors of the terminal block on the PSU board. If the
output current exceeds I>2,5A, a Wheatstone bridge should be implemented at the +OUT1 i +OUT2 outputs.
If necessary, connect the device (alarm panel, controller, indicator, etc.) conductors to the technical outputs:
- BS output - indicates 230V power failure
During normal PSU operation, the BS technical output is disconnected from ground (‘-‘) and in the case of 230V AC
power loss it is connected to ground (‘-‘) after the time determined by Z1, Z2 jumpers (Tab 3).
- AW output - indicates failure
During normal PSU operation, the AW technical output is ground fault (‘-‘). If any of failures mentioned above
occurs, the output is cut off.
5. During battery-assisted operation, it is possible to determine time necessary for battery disconnection by the Z3,
Z4 pins (Tab.1) when the voltage at its terminals drops below 10.5V.
6. Determine the maximum charging current using the J1, J2 pins (Tab. 1).
7. Activate the ~230V/AC supply (the AC diode and the AUX diode should be permanently illuminated)
Check the output voltage (the PSU voltage without load should amount to 13,6 V÷ 13,9 V, during battery charge:
11,0 V÷13,8 V). If the value of the voltage requires adjustment, it should be set by the V
ADJ
potentiometer,
monitoring the voltage at the AUX output of the PSU.
8. Connect the battery in accordance with the markings (colours: “+” red, „-„ black)
9. With the STOP button, initiate or finish a dynamic battery test (Tab.1)
Deactivating the test turns out the PSU failure indication at the AW output, but it does not affect the protection
system against complete battery discharge.
10. Run a PSU test: LED indication, acoustic indication, AW technical output; through:
- cutting off the 230V AC current: LED and acoustic indications – immediately; the BS technical output –
after some time, determined by Z1, Z2 pins.
- disconnecting the battery: LED indication, acoustic indication and the AW technical output – after a
battery test have been completed (approx. 20 min.)
11. With the ZB pin, decide whether the acoustic indication stall be on. (Tab.2)
12. Check the current consumption of the receivers without exceeding the total current capacity of the PSU.
13. Erase the failure memo of the PSU.
14. Once the tests and operation control have been completed, the enclosure can be locked.
3. Operating status indication.
3.1 Control panel operation
The PSU is equipped with a panel with buttons and a 3-digit LED display. It enables reading the main voltage
and current parameters of the PSU as long as browsing failures. The panel buttons are to be used for choosing
and approving a parameter that is to be displayed.
