INSTRUCTIONS FOR USE
• 1 operating status LED, "Start/Stop" (yellow colour); indicates whether output is in accordance with
selected mode
• 2 operating mode LEDs, "Function": Flash or Charge (yellow LED)
• 4 supplied current LEDs, "Amperage", described below (yellow LED)
• 3 supply voltage and battery type LEDs, "Volt/Batt", described below (yellow LED).
The front panel of the battery charger accommodates 5 buttons:
• "Start/Stop": starts or stops supply in selected mode
• "Function": selects operating mode
• "Volt/Batt": selects supply voltage or type of battery to charge
• "Amperage": selects supplied current
• "A/V" (display): selects information to display
DIGITAL DISPLAY
The "A/V" selector button selects voltage or current display.
BATTERY CHARGER FEATURES AND OPERATING MODES
A) Operating modes: "Function"
Charge
Battery charging mode. There are 7 charging steps, as described below:
• STEP 1: Test 1. If battery output is above 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. Charge starts at a constant current, until battery voltage reaches 13V.
• STEP 3: Test 2. Checks whether the battery has short-circuited elements. The battery charger stops
supplying current for 5 minutes. If during this time battery voltage falls below 11.7V, the device reverts to
stand-by. If voltage remains above 11.7V, the battery charger moves 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 is reached.
• STEP 5: Constant voltage. Keeps the battery at charge end voltage.
• STEP 6: Buffer. Voltage falls to the maintenance level and the charging cycle is completed. The green FULL
LED turns on.
• STEP 7: Pulsed current cycle. Pulsed battery maintenance cycle (over long periods).
Flash
Power Supplier mode assisting in motor vehicle programming. No charge phase occurs in it. It is just a
power supplier stabilized at rated 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: Test 1. If battery output is above 3V, the unit proceeds with the next step. Outputs below 3V
will cause the device to revert to stand-by.
• STEP 2: Pre-charge. Charge starts at a constant current, until 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 charge end voltage.
• STEP 5: Buffer. Voltage falls to the maintenance level and the charging cycle is completed. The green
