Operation ILR2250-100
optoNCDT ILR2250
The switching outputs are activated depending on the output level set (switching behavior) and the range check.
The switching outputs are activated if the target is outside
- the measuring range (analog output),
- the range limits (upper/lower limit).
A lower and an upper limit value (in mm) need to be entered in order for the range limits to be monitored. Notes about
switching behavior are available under Electrical Connections,
see Chap. 5.4.7 .

Example
- Switching output 1:
Monitoring of upper and lower limit
- Switching output 2:
Measuring range error
EMR = End of measuring range
Teach = Distance is outside the
scaled analog output
UL = Upper limit
LL = Lower limit
HV 1 = Hysteresis switching output 1
HV 2 = Hysteresis switching output 2

If you want to monitor whether the target leaves the measuring range limits (SMR and EMR), you can do this using the
Limit function. You will need to set the values for the upper and lower limit to the value for the SMR and EMR; the hyster-
esis value is not taken into account.
If you want to monitor whether the target leaves the region of interest (min and max), you can do this using the Limit
function. You will need to set the values for the upper and lower limit to the min and max values; the hysteresis value is
not taken into account.
6.8 Measured Value Holding Mode, Error Handling
The error handling function regulates the behavior of the analog output and RS422 interface in the event of an error.
Error handling None The analog output delivers approx. 3 mA instead of the measured value. The
RS422 interface outputs an error value.
Infinite The analog output and RS422 interface remain on the last valid value.
Count Value
Value range [1 ... 2147483645], last value held for n
cycles, then an error value is output.
If no valid measured value can be determined, an error is output. Alternatively, if this interferes with further processing,
the last valid value can be held, i.e. output repeatedly, for a certain amount of time. After the selected number of cycles
have elapsed, an error value is output.
