Remaining Device Lifetime (Remain. Dev. Life.) - Siemens SITRANS LR260 Operating Instructions Manual

3.14.3. Minimum Internal Temperature (MIN. INTERN. TEMP.)
Read Only. Displays (in degrees C) the minimum temperature recorded by the
internal electronics. The high and low values are maintained over a power
cycle.

3.15. Remaining Device Lifetime (REMAIN. DEV. LIFE.)

Notes:
• 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, Service
Interval, and Calibration Interval.
• Performing a Device Reset to Factory Defaults using the handheld programmer
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 Total Expected Device Life.
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. 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.
• 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 Device Life.

In device, Maintenance parameters are displayed in years. In SIMATIC PDM, mainte-
nance parameter units are user selectable.
