Device settings:
(The device is first restored to factory settings before being commissioned)
TV0 selected: Transmitter Variable 0 is PV
Lower Range Value (0% of range) is set to 14.3
Upper Range Value (100% of range) is set to 75.8
Current loop is in 2-state mode (C: Hi selected)
2-state fault signalling enabled (F: Hi selected
Activation hysteresis is set to 90
Deactivation hysteresis is set to 8
USL is set to 83.50 pF
LSL is set to 7.3 pF
When the process level reaches 90%, the probe is considered covered and the output will
be 20 mA. If the level exceeds USL, the output will be 22 mA. When the process level
drops to 8%, the probe is considered uncovered, and the output will switch to 4 mA. If the
level drops below LSL, the fault signal will be 22 mA.
