Remaining Device Lifetime (4.2.); Lifetime Expected (4.2.1.); Time In Operation (4.2.2.); Remaining Lifetime (4.2.3.) - Siemens SITRANS LR560 Operating Instructions Manual

Parameter Reference
8.4 SERVICE (4.)
8.4.2

REMAINING DEVICE LIFETIME (4.2.)

Note
• 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 SENSOR LIFETIME (4.3.) (Page 148), SERVICE
SCHEDULE (4.4.) (Page 150), and CALIBRATION SCHEDULE (4.5.) (Page 152).
• 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
(via AMS Device Manager only) see REMAINING DEVICE LIFETIME (4.2.) (Page 146).
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 alerts, and
acknowledge them.
The maintenance warnings and alarms are communicated to the end user through status
information. This information can be integrated into any Asset Management system.
To access these parameters via AMS Device Manager, see Remaining Device Lifetime
under Device Diagnostics (Resource Block-RESOURCE) (Page 98).
