Remaining Device Lifetime (4.2.); Lifetime Expected (4.2.1.) - Siemens SITRANS L Operating Instructions Manual

7.5.2

Remaining device lifetime (4.2.)

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 Remaining sensor lifetime (4.3.) (Page 126), Service schedule (4.4.)
(Page 129), and Calibration schedule (4.5.) (Page 132).
• 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 (via SIMATIC PDM only) see Lifetime expected (4.2.1.) (Page 123).

The device tracks itself based on operating hours and monitors its predicted
lifetime. You can modify the expected device lifetime, set up schedules for
maintenance reminders, and acknowledge them.
The maintenance warnings and reminders are available through HART
communications. This information can be integrated into an Asset Man-
agement system. For optimal use, we recommend that you use SIMATIC
PCS7 Asset Management Software in conjunction with SIMATIC PDM.
To access these parameters via SIMATIC PDM:
1. Open the menu Device – Maintenance and select the Remaining De-
vice Lifetime tab.
2. After modifying values/units as required, click on Write to accept the
change, and Read to view the effect of the change.
3. Click on Snooze to add a year to the Total Expected Device Life.
10.00 years
