Alarms - LAUMAS TLU Installation And User Manual

the load cell is not connected or is incorrectly connected; the load cell signal exceeds
:
39 mV; the conversion electronics (AD converter) is malfunctioning; the load cell is a 4-
wire and there are no jumpers between EX- and REF- and between EX+ and REF+.
the weight display exceeds 110% of the full scale.
:
: internal instrument converter failure; check load cell connections, if necessary contact
technical assistance.
: the weight exceeds the maximum capacity by 9 divisions.
maximum displayable value exceeded (value higher than 999999 or lower than -999999).
:
: appears when there is the attempt to zero set a weight value from an external contact or
from serial greater than the set value in the parameter .
: this message appears in the sample weight setting, in real calibration, after the fifth
sample weight value has been entered.
the value set for the parameter is beyond the permitted values; press ESC to quit the
:
setting mode leaving the previous value unchanged. Examples: a number of decimals is
selected for full scale which exceeds the instrument's display potential; value above the
maximum setting value; the weight value set in sample weight verification does not match
the detected mV increase; the analog output correction goes beyond the permitted limits.
: lock active on menu item, keypad or display.
: It's not possible to display properly the number because is greater than 999999 or less
than -999999.
