4.3. Remaining Sensor Lifetime

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 (4.2.), Service
Schedule (4.4.), and Calibration Schedule (4.5.).
• 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 (4.3.1.).
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.
• 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.
