SIGNALLING LEDS
The front panel of the battery charger accommodates 15 LEDs, including 4 battery status LEDs,
indicating the following:
• "Full": battery is charged, and is in charge maintenance status
• "Charging": battery is charging
• "Fault": battery is damaged
• "Reverse": polarity reversal
• 1 battery charge status LED, "led ON" (blue colour)
• 1 operating status LED, "Start/Stop" (yellow colour); indicates whether output is in accordance with
selected mode
• 2 charge voltage LEDs, "Voltage", described below (yellow LED)
• 4 charge function LEDs, "Function", described below (yellow LED)
• 3 battery type LEDs, "Batt" , described below (yellow LED).
The front panel of the battery charger accommodates 5 buttons:
• "Start/Stop": starts or stops supply in selected mode
• "Voltage": selects operating mode
• "Function": selects operating mode, Charge or Flash
• "Batt": selects type of battery to charge
• "A/V" (display): selects information to display; voltage or current
BATTERY CHARGER FEATURES AND OPERATING MODES
Charge (12V batteries)
Battery charging mode. There are 7 charging steps, as described below:
• STEP 1: Test 1. If battery output is above 7.5V, the unit proceeds with the next step. Outputs below
7.5V 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 (the message "tESt" is shown on the display). 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.
Minimum battery voltage
For the two modes, "Charge & Flash", use the RECOVERY feature if battery voltage is below the
following values:
• 6V battery – measured voltage: 4V
• 12V battery – measured voltage: 7.5V
• 24V battery – measured voltage: 15V
Recovery (12V batteries)
Recovery mode for sulphated batteries accessible by a prolonged press of the "Batt" key. The screen
