GRAUPNER LIPO-QUICK-CHARGER 4 Operating Manual page 9

Using the charger for the first time
This method of operation charges the pack to
100% of full capacity, at the same time avoiding
battery damage and overloading.
"Battery charged" mode
As soon as the battery has reached 100% of
charged capacity, the charger automatically
switches off the process. This is indicated by
the blue LED (1 - 3 cells) flashing at one-second
intervals, or by the red LED (4 cells) flashing at
one-second intervals. You will also hear an au-
dible signal at one-second intervals; this signal
continues for about 15 seconds.
Do not be surprised if the battery is cool or
just barely warm after a full charge. This is
completely normal, as the LiPo-Quick-Charger
4 automatically reduces the current towards the
end of the charge process.
Disconnect the charged battery and press the
START/STOP button; the LiPo-Quick-Charger 4
now reverts to Stand-by mode.
The blue LED flashes at three-second intervals
to indicate Stand-by mode.
Error mode
The LiPo-Quick-Charger 4 includes a range
of sophisticated safety functions designed to
protect the battery and the charger.
For example, the device is protected against
reversed polarity at the input and output.
If you accidentally connect the charger with
reversed polarity, the 7.5 A / 32 V fuse may
blow, in which case you will have to fit a replace-
ment fuse.
Spare fuses are available from any good electri-
cal goods supplier.
If one of the following errors occurs, the Li-Po
Charger 4 switches to Error mode.
This mode is indicated by both LEDs (blue and
red) flashing. At the same time the unit emits an
audible warning signal at one-second intervals.
You can identify the type of error by counting the
number of flashes from the two LEDs before a
short pause occurs, during which you will again
hear the audible warning signal.
LED Error
1x Input voltage below 10.5 V or above
15 V
2x Battery connected to charge output with
reversed polarity
3x No battery connected to charge output
4x Incorrect cell count selected
5x Incorrect battery type connected
(eg. Ni-Cd / Ni-MH)
6x Problem with charger circuit
(send charger to Graupner Service
Centre)
If the charger does not work at all when con-
nected correctly to a suitable power source, and
fails to produce any audible or visual indicators,
remember to check the fuse (7.5 A / 32 V).
If the fuse has blown, remove it and fit an identi-
cal replacement fuse.
