- Battery failure
:
-
control voltage lower than 10,5 Vdc battery not
connected, battery resistor > 1 ohm
- Battery OK:
- voltage included between 10,5 Vdc and 14,0 Vdc
- Overcharged battery:
- voltage over 14,0 Vdc
- Mains:
- presence of line voltage 230 Vac
- Failure:
- Led of general failure, it activates in case of:
absence of 230 Vac mains - faulty fuse -
loss of battery charge - Low battery -
overcharged battery
Indications on the front panel (located on the door of the power supply )
Connection of control board (placed behind the front panel)

Relay-exchange output with intervention for mains missing with programmable activation delay:
Jumper on
JP1
to have a delay of 15 seconds
Jumper on
J1
to have a delay of 15 minutes
Jumper on
J2
to have a delay of 60 minutes
Note: if no jumper is inserted, the “mains missing” relay will never activate.
Relay of “power-supply failure” – terminals 7 – 8 – 9 (operating with SELV voltages)
Relay-exchange output for failure indication, it activates for:
Output low-voltage
Interrupted outputs fuses
Interrupted battery-charge fuse
Missing battery-charge

Relay-exchange output for failure indication. It activates for:
Low battery
Battery not connected
Resistance battery > 1
Ω
Start of the system:
even if not imperative, the following sequence of connection is suggested:
1. Connect mains and ground to the concerned terminal J1. The charge Led flashes and after about 30 seconds the missing
battery Led flashes
2. Connect the battery. After 20 seconds the Led switches off
3. Connect the charges: the Leds indicating the current supplied light up
SERVICING
Periodical programmed servicing must be carried out by qualified personnel in order to prevent the possibility of a malfunct ioning of
the power supply. It is recommended to carry out servicing every 6 months and to evaluate control panel of the system in order to
check possible alarms during tests.
-
Check the connections of the 230 Vac supplying lines
-
Check the connections of the alarm indication lines and related shields
-
Check the battery connections, they have to be well tightened and there must be no oxidation
-
Check the output voltage on the charge (see electrical specifications)
Although the power supply is equipped with a self-diagnosis system carrying out a periodical control of the battery and indicating
possible failures, it is suggested to manually check the battery every six months.
-
Disconnect the battery and check if the voltage of the power supply is within the values shown.
-
After re-connecting the battery, disconnect the primary supplying and check if the battery can maintain the voltage on the higher
12Vdc charge. On the contrary, replace battery immediately.
-
Check presence of related alarms during tests.
LED SYNOPTIC PANEL
The DL2 Led shows the failures:
In case of contemporary presence of more alarms, the Led indication follows the priority shown in the chart
