Pilot Lamps:
"Battery Full"
Battery (Batteries) fully charged,
green
) **:
If it is on:
Battery (batteries) has (have) been charged to 100 %, trickle charge U2 and storage charge U3,
finished.
If it is flashing:
Main charging process is effected in the charging phase U1, the display of the residual charging
time rises gradually from approx. 75 % (lead) or 90 % (LiFePO4) (short flashing) to 100 % (long
flashing).
Off:
Main charging process is still effected in the phase I.
"Main Charging"
(Main charging,
yellow
) **:
If it is on:
Main charging process is effected in the phase I and after that in the charging phase U1.
Off:
Trickle charge U2 or U3.
If it is flashing:
1. Battery temperature sensor at terminals "
I
T T
" is not connected (only with LiFePO4).
2. External overvoltage battery
I
or
II
, > 15.50 V 20 sec. disconnection,
automatic reset after drop to the nominal voltage.
"Current"
(Charging Current,
red
):
If it is on:
The lighting intensity will be
reduced or increased
depending on the
supplied charging current.
Off
Charging current is less than approx. 0.2 A
"Battery
I
"
(
yellow
)
:
If it is on:
Charging port "
I
" is active.
Off:
Charging port is blocked (safety switch).
If it is flashing:
Battery protection: Battery overtemperature
"
I
"
> 50 °C:
Switchover to low safety charging voltage and half of the max. charging current,
automatic return in case of slightly dropped temperatures.
Turns off shortly: Is lighting longer and turns off shortly approx. every 1.5 sec., only with charging program LiFePO4:
Li battery protection, battery temperature below 0 °C, the charging current might be reduced for
protection of the Li battery, in case of discharged battery, longer charging times can be expected.
"Battery
II
"
(
yellow
)
:
If it is on:
Charging port "
I
" is active.
Off:
Charging port is blocked (safety switch) or low voltage < 7 V.
"Power"
(Mains,
red)
:
If it is on:
Mains supply is available and charger is ready for operation.
If it is flashing:
1. Disconnection by the safety timer, duration of the charging phase I was too long (> 15.5 h),
excessive current consumption by consumers, battery defective (short-circuit of the cells).
Reset is only possible by withdrawing the mains plug.
2. Internal unit failure (overheating), automatic reset after cooling down.
**
"Battery Full"
and
"Main Charging"
are flashing
slowly and alternately
:
The charging program
5)
Li Storage
is active (such as during seasonal operation).
It automatically maintains an advantageous charging state of 50-80 % of the LiFePO4 battery, when
the vehicle is stopped. This charging state is advantageous for the battery lifetime. See
page 5.
Return
from this function to the standard charging program LiFePO4:
Only
possible by pressing the
key "Silent Run"
for more than
4 seconds
.
Withdrawal of the mains plug does not have any effect!
During power pack operation (without batteries or with defective fuse) the active charging ports provide the
desired charging voltage. The LEDs "
I
" and "
II
" are still lighting.
Further actions or maintenance at the unit are not required.
