Status codes
If a fault occurs during operation, specific status codes may be displayed. Faults can result
from the following:
- Battery is connected with reverse polarity
- The voltage of the connected battery is unsuitable
- The device has overheated
- There is a software or hardware fault
If an error message appears on the display and if you cannot resolve the error yourself:
Note the displayed status code: e.g. "Statecode (31)"
Note the configuration of the device
Contact After-Sales Service
Freely-defined text, which could for example include the contact details of the dealer,
can be displayed if the device is in an error state. More information can be found in the
"USB mode" section.
Status codes caused by external factors
Number Cause
(11) Mains overvoltage or undervoltage
(13) External temperature sensor faulty
(14) Electrolyte circulation faulty (pressure switch not switching)
(16) External start/stop is not closed
(17) Open circuit voltage detection triggered more than once during charging
(e.g. worn charging contacts)
Status codes in the event of a battery fault
Number Cause
(22) Battery undervoltage
(23) Battery overvoltage
(24) Battery too hot (with external temperature sensor only)
(25) Battery too cold (with external temperature sensor only)
(26) Cell fault detected
(29) Battery is connected with reverse polarity
Status codes in the event of a charging error
Number Cause
(31) Timeout in I1 phase
(32) Timeout in U1 phase
(33) Battery overvoltage in the I2 phase
(34) Ah limit exceed
(35) Timeout in I2 phase
(36) Target voltage in I2 phase not reached (with format characteristic only)
