If the charger detects an excessive cell voltage at the
balancer input, this error message appears.
h i .
The error message appears at the following voltages:
LiPo > 4.3 V, LiIo > 4.2 V, LiFe > 3.9 V, NiCd / NiMH > 2.0 V
This error message may also appear if the cells
connected to the charger are overcharged.
If the charger detects an excessively low cell voltage at
the balancer input, this error message appears.
The error message appears at the following voltages:
l o w
LiPo < 2.75 V, LiIo < 2.75 V, LiFe < 2.0 V, NiCd / NiMH <
0.1V
If this should occur, we recommend that you give the
battery an initial charge for example in the LiFe Program
Mode for a few minutes (max. five minutes), which allows
cell voltages down to 2.0V without connecting the
balancer plug.
Warning: it may be that the battery contains
damaged cells, and the battery pack must therefore
be monitored very closely while it is being recharged.
As soon as the voltage is high enough, for safety
reasons the battery must always be charged with the
balancer plug connected (explosion and fire
hazard!).
When starting in NiCD/NiMH balance mode, if the
balancing connector is not connected to the balancing
port of the charger, this error should occur.
While the balancing connector is connected to the
balancing port of the charger, if the balancing connector is
disconnected from the balancing port of the charger
during charge or discharge, this error should occur.
