Functional description
Display in Charger mode Display in Power Supply mode Code Bedeutung
Charger overvoltage OV 01 Overvoltage error
Charger overtemp. OT 02 Overtemperature error in the device
Charger system error SYS 03 System error
CAN communication error CAN 20 CAN communication error
Bat. temp out of range 37 Battery temperature too high
Bat. temp out of range 38 Battery temperature too low
Bat.voltage out of range Ub> 39 Battery voltage too high
Bat. deeply discharged 40 Battery voltage too low
Cell fault in battery 41 Cell short-circuited or defective
Temp.sensor fault 42 Temperature sensor missing or defective
Reverse polarity -Ub 43 Battery connect with reverse polarity
No battery detected 44 No battery connected (only in charger mode)
Some explanations about the list:
• No battery detected is displayed in charger mode
as long as no battery is connected (battery voltage =
0V).
• Bat. deeply discharged indicates that the connected
battery is either deeply discharged, defective or just of
wrong nominal voltage.
• if a battery is connected while the device is in Power
Supply mode, the battery voltage is supervised like
in Battery Charger mode and related errors are re-
ported.
