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.), Service Schedule (4.4.), and
Calibration Schedule (4.5.).
• 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 under Maintenance &
Diagnostics (RESOURCE) (Page 95).
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.
