Automatic Charging; End Of Charging - Telwin Digitrony 230 Start Instruction Manual

For very flat or sulphated batteries TEST mode is not
available.
9- Display for showing the selected parameter. The
display also shows a number of abbreviations relating
to the present status/mode (FIG. C).
5. OPERATION
BEFORE CHARGING
NB: Before charging check that the capacity of the
battery (Ah) which is to be charged, is not inferior to
that reported on the data table. (C min).
Follow the instructions, taking great care to respect
the order given below.
- Remove the caps of the battery charger (if foreseen)
so as to let the gas produced go out.
- Check that the level of the electrolyte covers the plates
of the battery. If these were not covered add distilled
water and cover them up to 5-10 mm.
WARNING: USE THE MAXIMUM CAUTION
DURING THIS
ELECTROLYTE IS A HIGHLY CORROSIVE
ACID.
- Please remember that the exact charge status of the
battery can only be determined by using a densimeter
which allows measurement of the specific gravity of
the electrolyte the following indicate approximate
density values for the solute (Kg/l at 20°c):
1.28 = charged battery;
1.21 = half-charged battery;
1.14 = flat battery.
- With the power supply cable disconnected from the
mains socket connect the load terminals according to
the rated voltage of the battery being charged or else
position the 12 / 24 switch (if present) according to the
battery being charged.
- Position the switch/es for adjusting the type of charge
(if present) as required (FIG.D: LOW normal charging,
HIGH rapid charging).
- Check the polarities of the battery terminals: positive
for the + symbol and negative for the - symbol.
NOTE: if the symbols are indistinguishable remember
that the positive terminal is the one not connected to
the vehicle chassis.
- Connect the red charge clamp to the positive terminal
of the battery ( + symbol).
- Connect the black charge clamp to the vehicle chassis,
at a safe distance from the battery and the fuel pipe.
NOTE: if the battery is not installed in the vehicle,
connect the clamp directly to the negative terminal of
the battery (- symbol).
- Power the battery charger by inserting the power cable
in the mains outlet and turning the main switch ON.
- Check the battery voltage and make sure that the
settings on the battery charger panel are compatible
with the specifications of the battery being charged.
These checks should be carried out with the
corresponding key in "Test" mode.
CHARGING
- Press the corresponding key to switch to "CHARGE"
mode
- Monitor the battery voltage and charge current
parameters on the display using the V / I key
(FIG.B-7).
- The value shown on the display as parameter "I" shows
the battery charge current (in amps): during this phase
it will be observed that the value slowly decreases
to very low values depending on the capacity and
condition of the battery (Fig.B-9),
- The battery voltage can be constantly monitored on
the display as parameter " V ".
NOTE: Once the battery is charged you may note the
liquid inside the battery starting to "boil". It is advisable to
stop charging when this phenomenon appears so as to
prevent damage to the battery.
OPERATION AS
AUTOMATIC CHARGING
Press the corresponding key to pass to "TRONIC" mode
During this phase the battery charger will constantly
monitor the
automatically supplying or cutting off the charge current
to the battery as necessary.
Also in this case it is possible to monitor the battery
voltage and charge current on the display using the V
/ I key.
The charge current can be set as illustrated. When it is
cut off the display will show the message "END".
WARNING: SEALED BATTERIES (GEL, AGM)
If it is necessary to charge this type of battery
take great care. Charge slowly keeping an eye
on the voltage over the battery terminals.
When this voltage, available as parameter "V" on the
display, reaches 14.4V for 12V batteries (28.8V for
24V batteries) we recommend you stop charging.
THE For models where foreseen, it is advisable to set the
automatic function "TRONIC".
Simultaneous charging of several batteries (FIG. E)
This operation must be performed with great caution:
WARNING; do not simultaneously charge different types
of batteries or batteries with different capacities or levels
of discharge.
If you have to charge more than one battery at the same
time you can connect them "in series" or "in parallel". Of
the two systems, we recommend connecting the batteries
in series because in this way it is possible to monitor the
current circulating in each battery, which will be the same
as that shown by the " I " parameter on the display.
NOTE: If two batteries with rated voltages of 12V are
connected in series, the corresponding button must set
the battery charger to 24V.
END OF CHARGING
- Press the corresponding key to switch to "TEST"
mode.
- Remove the power supply from the battery charger by
turning the switch to OFF (if present) and/or removing
the power supply cable from the mains outlet.
- Disconnect the black charge clamp from the chassis of
the vehicle or from the negative terminal of the battery
(- symbol).
- Disconnect the red charge clamp from the positive
terminal of the battery (+ symbol).
- Store the battery charger in a dry place.
- Close up the battery cells with the appropriate plugs (if
present).
STARTING
Before starting the vehicle, make sure the battery
is connected properly to the respective (+ and
-) terminals, and that it is in good condition (not
sulphated or dud).
Never ever start vehicles with the batteries
disconnected from their respective terminals; the
presence of the battery is essential for the elimination
of possible overvoltage that may be generated due to
energy accumulating in the connection cables at the
starting stage.
For starting turn the switch to the starting position
corresponding to the voltage of the vehicle. n this mode
the display will show only and exclusively "Str".
Before turning the starter key, it is essential to make a
rapid charge of 5-10 minutes, which will make starting
much easier.
Rapid charging should always be done with the
battery charger switched to the charge position and
NOT to starting.
