3.3.4. Remaining Sensor Life
Notes:
• 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.), Service Schedule (3.3.5.), and Calibration Schedule (3.3.6.).
• 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 Sensor Lifetime
parameters in hours or days (only via SIMATIC PDM, PACTware FDT, and
AMS) see Lifetime Expected (3.3.4. 1 .).
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
Communications manual.
