7
RED LED:
on
– the PSU is supplied with 230V AC
off
– no 230V AC supply
GREEN LED:
on
– DC voltage in the DC output of the AUX
off
– no DC voltage in the DC output of the AUX
3. Operating status indication.
3.1 LED indication
The PSU is equipped with two diodes in the front panel.
3.2 Technical output:
The PSU is equipped with technical output:
TAMPER - output indicates opening the power-supply unit
.
The output’s volt-free (potential-free) contacts
indicate PSU door status:
- unit closed: NC,
- unit opened: NO
4. Operation and use.
4.1 Overload or short circuit of the PSU output
The AUX output is equipped with a protection due to a PTC polymer fuse. If the load of the PSU exceeds
I
max
(load 110% ÷ 150% of the PSU power @65 ºC÷25ºC) the output voltage is automatically cut off and indicated
by the green diode going out. To restore the output power and to protect the PTC, cut off the output load for
approximately 1 minute.
In the case of a short-circuit to the AUX, BAT output
(load 200% ÷ 250% of the PSU power) or a reverse
polarity connection, the F
BAT
fuse in the battery circuit becomes permanently damaged and the restoration of the
voltage at the BAT output requires replacement of the fuse.
4.2 Battery-assisted operation.
Immediate battery reverting in case of main power outage.
In order to run the PSU from the battery only, connect the BAT connectors in accordance with the signs:
+ BAT red to ‘plus’ and, - BAT black to 'minus’ then press the START button on the main board and hold it for 5
seconds.
The PSU contains the discharged battery disconnection system (UVP), configured through
the P
BAT
pins. The battery protection is on after removing the P
BAT
jumper.
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 the
case of significant dust rate, its interior is recommended to be cleaned with compressed air. In the case of a fuse
replacement, use a replacement of the same parameters.
