7.3. Description of States of Error
When an error occurs, the terminal reads out an error message in place of weight. Apart from underload
and underload, every error message has to be acknowledged by pressing key 'Set to zero'. Depending on
the type of error, the terminal will either restart or continue its operation. Trace the cause of the error and
eliminate it whenever it occurs one more time. 7.3 shows all possible error messages as well as possible
sources of error.
Error
Message
Error Cause
∪∪∪∪∪∪ underload (compound scale: possibly
followed by number of channel with
underload) load carrier is lifted, load cell(s) defective,
faulty measuring cable

followed by number of channel with over-
load) excessive load, load cell(s) defective, faulty
measuring cable
