MANUAL DO UTILIZADOR
Rev nº 1 de 14/01/2015
•
Do not modify the chargers, and in particular their safety systems.
•
Check regularly all internal electrical connections. Make sure that cables and terminals have not been damaged by
overheating due to bad contacts ; remove dust (in particular from contactor and moving parts).
•
Before cleaning the charger, disconnect it from mains and battery.
•
Battery chargers do not need any special maintenance, apart from the usual cleaning which has to be performed
regularly depending on the installation site.
•
The unit must not be used by unskilled or unqualified personnel, children or people with reduced physical and mental
abilities.
B)
CONNECTION TO MAINS
The charger three-phase is pre-set for a
three-phase mains supply of 400V AC
. Should the charger be set for a
three-
phase mains supply of 230V AC
, perform voltage adjustments on
the terminal board
, retap
taps on the auxiliary
transformer
, and
install the suitable mains fuses.
The
single-phase
version is preset for operating at
230V AC
.
In case of connection to a power supply protected by Automatic Circuit Breaker, use only SWITCHES with D or K curve
Make sure
to earth the charger properly
.
C)
ADJUSTMENT TO MAINS VOLTAGE
Check mains voltage and adjust it, if required, by means of the
adjusting terminal board
on the transformer.
D)
CONNECTION TO BATTERY
We advise the use of
bipolar standard connectors
which do not allow reverse polarity on battery.
Check
cable connection in the connector contacts
.
E)
E) DESCRIPTION OF A CYCLE OF CHARGE
-
Since the charger is equipped with
autostart
, the charging process will automatically start a few seconds after
connection (provided that the charger has detected mains presence).
-
The charging process stops automatically when the battery has been fully charged.
WARNING ! Never disconnect the battery connector while charging !
If you need to stop charging, switch-off the charger by pressing the ON/OFF push-button
-
The charging process begins only if battery voltage falls within the range foreseen for that charger.
-
If charging time exceeds the security timer (
7 hours
for a WOWa charger and
11h
for a Pulse charger
)
before reaching
gassing voltage, the charging process is automatically interrupted by a
safety timer
.
-
Another safety timer will interrupt the charging process if the overall charging time exceeds
15 hours
.
-
If a power failure takes place during the charging process, all data concerning the current charging process are
stored. On power-fail restart the charging process is resumed from the point reached before interruption.
EQUALIZING CHARGE
-
If battery charger remains connected to battery when the charge is over, an automatic equalizing charge will begin
after
16 hours
. The battery charger calculates battery capacity making use of the average capacity calculated in the
last 7 charging cycles duly completed.
-
During the equalizing charge the green LED will blink.
-
If battery remains connected to charger for a long time, a floating cycle will be performed
every 7 days
in the same
way as equalizing is performed.
F)
F) LED’s and DISPLAY INDICATIONS
-
All significant charging data are displayed on a backlit display: Cell Voltage, Charging Current, Restored Capacity (Ah),
Charging Time and Failure Messages, if any.
-
In addition three LED’s indicate the charge state.
