Service Schedule (3.3.5.) - Siemens SITRANS L 7ML5400 Operating Instructions Manual

9.3.3.5

Service Schedule (3.3.5.)

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), Remaining Sensor Life
(3.3.4.) (Page 254), 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 Service Interval (3.3.5.1.)
(Page 257).
The device tracks service intervals based on operating hours and monitors the predicted
lifetime to the next service. You can modify the Total Service Interval, set schedules for
maintenance reminders, and acknowledge them.
The maintenance warnings and reminders are communicated to the end user through status
information. This information can be integrated into any Asset Management 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:
• Open the menu Device – Maintenance and select the Service Schedule tab. (For more
details see Maintenance in LUT400Communications manual
