Operation; Setting Battery Voltage - Projecta HDBM4000 Instruction Manual

a. 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.
2. Check the polarity of the battery terminals: the (+) symbol is positive, the (- )
symbol is negative.
3. Connect the red clamp to the positive terminal on the vehicle battery (+ symbol).
4. Connect the black clamp to the vehicle chassis. Do not connect near the fuel pipe.
5. If the battery is not installed inside the vehicle, directly connect to the negative
battery terminal (- symbol).
Now the charger can be used to Charge a battery, Test the battery Voltage,
Test the cranking of the vehicle, Test the alternator, Perform equalization,
Sulphation and Power Supply modes (Diagnostic and Powersupply mode).
When finished using the charger
6. Disconnect the battery charger by removing the power cable from the
mains socket.
7. Disconnect the black charge clamps from the vehicle or from the negative battery
terminal (- symbol). Disconnect the red charging clamp from the positive battery
terminal (+ symbol).
8. Return the battery charger to a dry place. Close the battery cells again, using the
relative caps (if present).

2.1 SETTING BATTERY VOLTAGE

Use the "BATTERY VOLTAGE" button (fig. A.21), to set the rated voltage for the
battery (fig. A.1) to be charged.
VOLTAGE SELECTION
BATTERY VOLTAGE
After connecting the clamps to the battery terminals:
– if the value detected is higher than the set value (fig. A.1), an "AL.2" error
message (fig. A.2) is displayed;
– if the value detected is lower than the set value, the display (fig. A.1) starts
to flash for 5 seconds giving time to change the voltage value displayed in
(fig. A.1).
NOTE. The no battery connected status is indicated by the flashing (fig. A.5) symbol.
