Starter Mode; Simultaneous Charging Of Multiple Batteries; Charge Ending; Battery Charger Protection - Telwin Doctor Start 630 Instruction Manual

given below.
4.1 BATTERY PREPARATION
If the battery to be charged is the WET type, the procedure is as follows:
- Remove the battery caps (if present), so that the gas produced during
charging can exit. Make sure the level of electrolyte covers the battery
plates; if they are not covered, add distilled water until they are
submerged by 5-10 mm.
ATTENTION! BE VERY CAREFUL WHILE CARRYING OUT THIS
OPERATION BECAUSE THE ELECTROLYTE IS AN EXTREMELY
CORROSIVE ACID.
4.2 BATTERY CHARGER/BATTERY CONNECTION
- Make sure the power cable is disconnected from the mains.
- With models having more than one charge voltage, turn the deviator
or the switch to the selected charge voltage. If there is no deviator
or switch, suitably connect the red crocodile clip (+ symbol) to the
specific battery charger terminal in correspondence with the selected
charge voltage.
- Connect the red charge clamp to the positive terminal of the battery
( + symbol). If the symbols are indistinguishable remember that the
positive terminal is the one not connected to the vehicle chassis.
- 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).

4.3 SIMULTANEOUS CHARGING OF MULTIPLE BATTERIES

WARNING: do not charge batteries of different capacities, discharges
or types. When simultaneous charging is required, it is possible to
use "series" or "parallel" connections:
series
parallel
For "parallel" connections the batteries must have the same rated voltage
(Volt), corresponding to that supplied by the battery charger and the total
of the Ah must fall within the charge range of the battery charger.
For "series" connections the batteries must have the same capacity (Ah),
and the total of the rated voltage of all the batteries must correspond to
the output rated voltage supplied by the battery charger.

4.4. CHARGE ENDING

- Disconnect the battery charger by removing the power cable from the
mains socket.
- Disconnect the black charge clamps from the vehicle chassis or from
the negative battery terminal (- symbol).
- Disconnect the red charging clamp from the positive battery terminal
(+ symbol).
- Return the battery charger to a dry place.
- Close the battery cells again, using the relative caps (if present).

5. STARTER MODE

ATTENTION: Before proceeding, read the vehicle manufacturers
instructions carefully!
- Make sure the power line is protected by fuses or automatic circuit-
breakers with sizes as indicated on the rating plate by the symbol (
).
- To make the starting process easier, quick charge the battery for 10-15
minutes, with the battery charger in charge and NOT starter position.
- If the vehicle does not start, wait a few minutes and then repeat the
rapid charge operation. Do not insist further if the vehicle motor does
not start; this could cause serious damage to the battery or even to the
electrical equipment in the vehicle.
5.1 BATTERY CHARGER/BATTERY CONNECTION
- Check before starting the vehicle that the battery nominal voltage
corresponds to the value indicated on the battery charger.
- Make sure the battery is connected properly to the respective (+ and
-) terminals, that the battery connections are correct and the battery is
in good condition (not sulphated or dead).
- 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.
Failure to comply with these instructions can cause damage to the
vehicle electronic system.
5.2 STARTER
- To select this function, please refer to "STARTER" illustration.
5.3. STARTING COMPLETED
- Disconnect the power cable plug from the mains socket.
- Disconnect the black charge clamp from the negative battery terminal
(- symbol) and the red clamp from the positive battery terminal (+
symbol).
- Return the battery charger to a dry place.

6. BATTERY CHARGER PROTECTION

The battery charger protects itself from:
- Overcharge (too much current supplied to the battery).
- Short-circuit (loading clips placed in contact with each other).
- Polarity inversion on the battery clamps.
For appliances fitted with fuses, if the fuses have to be replaced always
use the same kind of fuse with the same rated size.
WARNING: If the replacement fuse has a different size from
that shown on the rating plate it could cause damage to
people or property. For the same reason, never ever
replace the fuse with a bridge in copper or other material.
The power supply cable should always be DISCONNECTED from the
mains supply while the fuse is being changed.
When replacing the ribbon fuse, if present, carefully fasten the nuts.
7. USEFUL ADVICE:
- Clean the positive and negative terminals from possible oxide
deposits to guarantee good clamp contact.
- If the battery to be recharged using this apparatus is permanently fitted
inside the vehicle, consult the "ELECTRIC SYSTEM" or "MAINTENANCE"
sections of the vehicle instruction and/or maintenance manual.
