Karcher TB 50 [13/168] Troubleshooting

Karcher TB 50 [13/168] Troubleshooting
Prior to the initial use of the radio control station, the battery pack
must be fully charged.
Note
The charge time may last up to three hours.
Connect the charging bowl to the jack plug of the power supply.
Insert the battery into the charging bowl and lock it.
Plug in the mains plug.
After the connection to the power supply, the LED will glow or-
ange first for a few seconds and changes over to yellow, once the
initialisation and the analysis begin. If the battery pack is connect-
ed, the actual charge begins a few seconds later, the LED glows
orange.
Continuously illuminated green: Battery is fully charged.
Transmitter and receiver have a STATUS LED, which indicates a
fault code in case of a fault. Fault codes will blink faster (2 x per
second) and will be displayed with a break of 1 second between
repetitions.
In case of an error, the status LED at the front of the transmitter
displays the cause of the fault. This is done via different blinking
sequences. The blinking sequences and the measures to remedy
the respective causes are as follows:
NiMH batteries
Charger (power supply and charging bowl)
Charging the battery
Charging cycle and LED display
LED Mode
yellow Battery not connected
yellow Battery initialisation and analysis
orange Rapid charge procedure
Green with a yellow
blinking light
Intermediate mode with low charging
voltage
green Conservation mode
alternating orange and
green blinking
