LEDs: charging status - Series 3N and 5N
Both 3N and 5N series are provided with 5 LEDs.
The leds can provide essential information on charging status of the battery and on possible alarms/error.
Legend:
-- = LED off
Visualisation of the charging phases
(For Alarms signals see section Troubleshooting)
Battery connected, charger is idle waiting for Vac supply or in alarm
Leds conditions during the first 5 sec. after the start
Bulk phase (battery < 2,4 Vel) Phase 1
Final charge . (Battery Voltage is > 2,4 V/el) Phase 2
End of charge. Battery is ready to be used
Equalisation or Preservation phase. Phase 3 and 4
LEDs also provide information about alarms .
To get all details please refer to the " Troubleshooting " table.
(*) The number after the letter P indicates the % of the battery charging status. See next paragraph

Single Parameter or Guide
"Single Parameter" or "Guide" has been designed to provide a "single " data that shows, depending on specific situation,
the status of the BC or an intuitive alarm code.
This parameter is available on all SERIE 5N (being equipped with display) or by connecting the optional keypad on all
SERIE 3N models.
"Single Parameter" or "Guide" then provides information that "changes" during the charge.
In particular during the charging process it shows the code P followed by a number from 10 to 99
The value indicates the percentage of power that has been given to the battery , so P 50 indicates that the battery has
reached 50 % of the charge , P 80 the 80 % and so on . This parameter gives an indication of the status of the process, it
is not a measuring instrument.
