Charge Sequence
Select a battery technology to ensure that the battery is
properly charged. To select any of the 4 positions press
the Multi Function and POWER button quickly. The top LED
(lead-acid) starts blinking. Pushing the Multi Function and
POWER button again within 4 seconds will scroll to the next
selection. This can be continued until the proper selection
is made. When the button is no longer pressed, the LED will
turn solid green indicating that that selection is activated.
With the charger clamps connected to a battery the LED will
turn to solid orange and starts charging.
The Multi Function and POWER button can be pressed at any
time during a charge cycle to stop the charger.
Position:
1. Lead Acid charge curve
2. AGM / SPIRAL charge curve
3. GEL charge curve
Power Supply Mode
Integrated in the charger is also a Power Supply function.
This mode ensured that the battery is kept fully charged
during programming of ECU’s or regular vehicle maintenance.
When the charger is not yet switched on, press and hold
down one of the Multi Function and POWER buttons for
more then two seconds. The unit will perform a self-test and
the green STATUS LED’s will light up to indicate charger is
ready and OK. In case of a problem the red LED will be lit.
This red LED is also used to indicate any error code in the
charger. The LED will blink at a certain rate.
To select the Power Supply Mode press any of the two
Multi Function and POWER buttons shortly until position 4
is reached. The LED will now turn to solid green. With the
charger clamps connected to a battery the LED will turn to
solid orange to indicate that it is in progress.
Any consumer in the vehicle that needs current will get this
from the charger. Only then, when current is needed in the
vehicle the charger will provide this, in any other situation
no current flows.
