3.7. Remaining Sensor Lifetime
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.
Notes:
• Default settings in the parameter tables are indicated with an asterisk (*) unless
explicitly stated.
• 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 (3.6.), Service
Schedule (4.7.), and Calibration Schedule (4.8.).
• 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 (via SIMATIC PDM only), see Lifetime Expected (3.7.6.).
