Connection of control board (placed behind the front panel)
Refer to picture 3
Relay “mains missing” – Terminals 10 – 11 – 12 (operating with SELV tensions)
Relay output with intervention for missing mains and programmable activation delay
Jumper on JP1 to have a delay of 15 seconds
jumper on J3 to have a delay of 120 minutes
Jumper on J1 to have a delay of 15 minutes
jumper on J4 to have a delay of 240 minutes
Jumper on J2 to have a delay of 60 minutes
In order for the power supply to be in conformity to the certification , the jumper must be set on JP1 or J1, as the norm talks
about a max delay of 30 MINUTES of missing mains. On the contrary, the conformity decades.
Note: if no jumper is inserted, the “mains missing” relay will never activate.
Relay of “failure indication” – Terminals 4 – 5 – 6 (operating with SELV tensions)
Relay output for failure indication, it is active for:
Low battery (tension lower than 22 Vdc)
Overcharged battery (tension over 28,5 Vdc)
Resistance battery > 1 ohm
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 malfunctioning 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 tension 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 tension 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 tension on the higher 23 Vdc
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
