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 Device Lifetime (4.2.), Remaining Sensor Lifetime (4.3.),
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 Service Interval parameters in hours or days (via
AMS Device Manager only) see Service Schedule (4.4.1.).
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 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 Service Schedule under
Maintenance & Diagnostics (LTB) (Page 85).
