Fault description Possible cause Remedy
 Er:X:14

Fault in the kg value
calculation

Wrong coefficients in the module’s ROM, reprogram and readjust the
scale
 Er:X:15

Recalibration fault  Reference weight outside the permitted range or operating fault
 Er:X:21

Fault in battery
voltage
measurement

Battery voltage much too low < 2.5 V or electronics defective
-> Replace the electronics
 Er:X:22

Temperature
measurement error

Replace the electronics
 Er:X:30

Data transmission
interrupted.

Check the bus connection, remove external sources of faults.
 Er:X:32

Command buffer
overflow fault

Check the bus cabling, eliminate the EMC fault, de-energize the
electronics for a short instant (60 secs)
 Er:X:33

To many modules
connected to bus

Reduce the number of modules connected to the bus.
 Er:X:40

No data on
EEPROM / data
deleted

Readjust the scale or reload the scale adjustment data to the
EEPROM via the service interface
 Er:X:41

Incorrect EEPROM
access

One of the modules connected accesses the memory in an incorrect
way. Determine the faulty module and replace it.
 Er:X:50

Software checksum
not correct

Fault immediately after switch-on -> wrong checksum in the ROM
-> Replace the electronics
 Er:X:51

Menu fault  Fault when operating the menu functions (impermissible values or
similar)
