Service manual Description of faults
20.02.01/Winterberg 1 (2) 30-34-00-588 index c
Description of the
fault
Possible
cause
Remedy
•
Er:x:11
•
Sensor is
defective or
supply lines
are damaged
•
Check connection cables, check sensor and replace as required
(if parts a replaced, a recalibration is necessary)
•
If several load cell are used, check the allocation (colour codes)
•
Er:x:12
•
Initial load is
too high
•
Check the initial load
•
Check the load lever (stuck or bent; check the sensor, replace it if
necessary and carry out a recalibration
•
Er:X:14
•
Error during
calculation of
the kg value
•
Incorrect coefficient in the read-only memory of the module;
recalibrate the scales
•
Er:x:15
•
Error during
recalibration
•
Reference weight is outside the permissible range or operator
error
•
Er:x:21
•
Error while
measuring the
battery voltage
•
Battery voltage is far too low (< 2.5 V) or electronics are defective
-> Replace the electronics
•
Er:x:22
•
Error while
measuring the
temperature
•
Replace the electronics
•
Er:x:32
•
Error:
command
buffer overflow
•
Check the cabling of the bus, eliminate any EMC malfunction,
briefly (60 sec.) de-energize the electronics
•
Er:x:40
•
No EEProm
data
•
Recalibrate the scale or write the correct EEProm data by service
program
•
Er:x:41
•
Incorrect
EEProm
access by the
slave
•
Check the slave; disconnect or replace the slave
•
Er:x:50
•
Other errors
•
Error occurs directly after switching on -> wrong checksum in the
ROM
-> Replace the electronics
•
Er:x:51
•
Menu error
•
Incorrect use of a menu function (wrong data e.g.), try it again
