Backup Control (3.3.2.); Remaining Device Life (3.3.3.) - Siemens SITRANS L 7ML5400 Operating Instructions Manual

9.3.3.2

Backup Control (3.3.2.)

LUI only. Determine source of configuration recovery file when sensor has been replaced.
Options
When sensor unit has been replaced, fault code 132 is displayed to note that LUI backup file
does not match configuration file in sensor. To clear fault, set Backup Control option to
location from where parameter configuration should be read; from the LUI backup file or
from the new sensor.
9.3.3.3

Remaining Device Life (3.3.3.)

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 Sensor Life (3.3.4.) (Page 254), Service Schedule (3.3.5.)
(Page 257), 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 Lifetime Expected (3.3.3.1.)
(Page 252).
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 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 Remaining Device Lifetime tab. (For
more details see Maintenance in LUT400Communications manual
Time Units
Allows you to set the desired units.
