Invalid switching values
You can define the switching point for an invalid column independent of the column value
for an invalid column. In the E
VALUATION
field you have four options:
Calculate
Even though the quality is not achieved, a switching value is determined from the
measured values available and is used.
Above level
Invalid switching values set the state to “Above switching point”.
Below level
Invalid switching values set the state to “Below switching point”.
Keep value
The previous state for the switching point is retained (above or below).

Digital outputs
The LMS400 has four digital outputs. In the R
ESULT
1 (OUT1) to R
ESULT
4 (OUT4) selection
boxes you have five options for linking the outputs:
Inactive
The output is not switched.
Above level
A single column switches the output if the switching point in this column is exceeded.
In the C
OLUMN
field enter the number for this column.
Below level
A single column switches the output if the switching point in this column is not reached.
In the C
OLUMN
field enter the number for this column.
Note
If the column entered is not activated or present, the output behaves as if you had
configured it as inactive.
All over switching point
All columns switch the output if the switching point in all columns is exceeded.
All under switching point
All columns switch the output if the switching point in all columns is not reached.
