BATTERY CHARGER FEATURES AND OPERATING MODES
A) Operating modes: "Function"
Charge
Battery charging mode. There are 7 charging steps, as described below:
• STEP 1: Analysis 1. If the battery output is less than 6.5V, the unit proceeds with the next step. Outputs below 6.5V
will cause the device to revert to stand-by.
• STEP 2: Pre-charge. The charge starts at a constant current, until the battery voltage reaches 13V.
• STEP 3: Analysis 2. Checks whether the battery has short-circuited elements. The battery charger stops supplying
current for 5 minutes. If during this time the battery voltage falls below 11.7V, the device will revert to stand-by.
If the voltage remains above 11.7V, the battery charger will move on to STEP 4. If any element short-circuits or the
battery becomes sulphated (as confirmed by message ERR02 on the display during STEP 3), the battery should
be charged in the RECOVERY mode.
• STEP 4: Deep cycle charging. The battery charges until the set limit value is reached.
• STEP 5: Constant voltage. Keeps the battery at the charging end voltage.
• STEP 6: Buffer. The voltage falls to the maintenance level and the charging cycle is completed. The green
FULL LED will turn on.
• STEP 7: Pulsed current cycle. Pulsed battery maintenance cycle (over long periods).
Flash
Power Supplier mode assisting in vehicle programming. No charge phase occurs in it. It is just a power supplier stabilized at the
nominal battery voltage. It is designed to deliver current supporting the battery, to prevent it from going flat during operations
which require power for short or long periods of time.
Recovery
Recovery mode for sulphated batteries accessible by a prolonged press of the "Function" key. The screen displays the message
"rEC" and shows the instantaneous voltage or current reading; during this step, the "Charge" LED flashes.
The battery charger performs a special charging cycle, in which higher than average voltages are forced, to attempt recovery of
the battery. In this mode, no error messages are generated during the charging cycle; when the cycle is completed, a message
is displayed to indicate whether or not the battery has been recovered on the basis of voltage or current absorption. This mode
has 6 charging steps, as described below:
• STEP 1: Analysis 1. If the battery output is less than 3V, the unit proceeds with the next step. Outputs below 3V will
cause the device to revert to stand-by.
• STEP 2: Pre-charge. The charge starts at a constant current, until the battery voltage reaches 13V.
• STEP 3: Deep cycle charging. The battery charges until the set limit value is reached.
• STEP 4: Constant voltage. Keeps the battery at the charging end voltage.
• STEP 5: Buffer. The voltage falls to the maintenance level and the charging cycle is completed. The green
FULL LED will turn on.
• STEP 6: Pulsed current cycle. Pulsed battery maintenance cycle (over long periods).
ATTENTION: Because of the high voltage reached during this charging cycle, the battery recovery process must be
performed with the battery disconnected from the vehicle. Recovery with the battery connected to the vehicle may
result in damage to the vehicle's electronics.
