7.7. Reranging (LRV/URV) – only for SIL 2 / PL d analog output version –
The IL transducer has an optional analog output on pin 5 with reference on pin 3 of M12 connector (only for SIL 2 / PL d analog output
version).
This output can be used as safety function for safety related applications up to SIL 2 / PL d.
The analog outputs available are:
• 0,5...10,5 Vdc (voltage output)
• 4...20 mA (current output)
For the analog output is also possible to remap the FS (4...20 mA or 0,5...10,5 Vdc) on a reduced FS input up to a 3:1 range; for
instance a 100 bar nominal FS transducer can be downranged up to 33 bar:
• LRV (Lower range value) = value in MU at which the transducer shall output 4 mA or 0,5 Vdc (it's set equal to 0 bar/psi by default)
• URV (Upper range value) = value in MU at which the transducer shall output 20 mA or 10,5 Vdc
LRV value is not allowed to be changed by customer (it's a read only parameter set by default to zero)
URV value can be changed under the following conditions:
• being a Specialist / Maintenance user
• LRV < URV
• 33%FS ≤ URV ≤ FS
Reranging does not affect at all IO-Link Process Data
Accuracy error is always referred to nominal Full Scale
NO Reranging
