8.6.16 Remaining Sensor Lifetime (REMAIN SENS. LIFE.) (3.16.)
Note
Four sets of parameters allow you to monitor the Device/Sensor Lifetimes and set up
Maintenance/Service schedules, based on operating hours instead of a calendar-based
schedule. See also Remaining Device Lifetime (Page 106), Service Interval (Page 105),
and Calibration Interval (Page 108).
The device operates in years. To view Remaining Sensor Lifetime parameters in hours or days
(via SIMATIC PDM only) see Total Expected Sensor Life (Page 102).
The device monitors the predicted lifetime of the sensor (the components exposed to the vessel
environment). You can modify the expected sensor lifetime, set up schedules for maintenance
alerts, and acknowledge them.
To access these parameters via SIMATIC PDM:
Open the menu Device – Maintenance and select the Remaining Sensor Lifetime tab.
After modifying values/units as required, click on Write to accept the change, and Read to
view the effect of the change.
Click on Snooze to add a year to the Total Expected Sensor Life.
Click on Sensor Replaced to restart the timer and clear any fault messages.
