RED LED:
on
– the PSU is supplied with 230V AC
off
– no 230V AC supply
GREEN LED:
on
– DC voltage in the AUX output of the PSU
off
– no DC voltage in the AUX output of the PSU
4.
Connect the receivers’ cables to the
AUX1…AUX9
connectors on the
LB9.
5. Connect the power (~230V)
6. Connect the battery (mind the colours):
- battery output (+V): BAT+ cable / red,
- battery output (- V): BAT
– cable / GND / black.
7. Check the PSU operation indicator: green LED.
8. Check the PSU output voltage:
- the PSU voltage without load should amount to U=13,8V DC.
9. After installing and checking proper working, the enclosure can be closed.
3. Operating status indication.
3.1 LED indication of operating status.
The PSU is equipped with two diodes on the front panel:
4. Operation and use.
4.1 Overload or short circuit of the PSU output (SCP on)
The
AUX1 ÷ AUX9
PSU outputs are protected against a short circuit by glass fuse.
In case of fuse damage, the replacement of the same parameters is required.
In case of overload, the output voltage is automatically shut off, and so is the LED indicator. The
restoration of the voltage takes place immediately after the failure (overload) is over.
4.2 Battery-assisted operation.
In case of a main power outage, the device is immediately switched into a battery-assisted operation.
The PSU is equipped with the discharged battery disconnection system. During the
battery-assisted operation, reducing voltage below 9,5V at the battery terminals will cause
battery disconnection.
4.3 Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU from the
power supply network. The PSU does not require performing any specific maintenance measures, however, in
case of significant dust rate, its interior is recommended to be cleaned with compressed air. In case of fuse
replacement, use a replacement of the same parameters.
