9.3 Maintenance and Diagnostics (3.)
9.3.3.4
Remaining Sensor Life (3.3.4.)
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 Life (3.3.3.) (Page 251), Service Schedule (3.3.5.)
(Page 257), and Schedule (3.3.6.) (Page 260).
• Performing a reset to Factory Defaults will reset all the Maintenance Schedule parameters
to their factory defaults.
• The device operates in years. To view Remaining Device Lifetime parameters in hours or
days (only via SIMATIC PDM, PACTware FDT, and AMS) see Lifetime Expected (3.3.4.1.)
(Page 254).
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 reminders, and acknowledge them.
To access these parameters via SIMATIC PDM:
• Open the menu Device – Maintenance and select the Remaining Sensor Lifetime tab. (For
more details see Maintenance in LUT400Communications manual
