Reset Type Result
Factory Defaults a) Default. Resets all user parameters to the manufacturer’s default settings.
Following this type of reset, complete reprogramming is required.
Standard Defaults Resets all parameters to standard default settings.
Informational Resets parameters such as Block Descriptor, Strategy, Device Install Date,
Device Message.
Functional
a)
Resets parameters that control device behavior and functionality (such as
Low Calibration Point).
Warm Start Has the same effect as recycling power to the device.
FF Object Dictionary Resets the FF standard block profile parameters (such as block tags) to
their specified defaults. This option also clears any function block parame-
ters and device schedule
b)
set by the user.
a)
The only difference between Factory Defaults and Functional reset is that Factory Defaults resets
maintenance parameters, such as device and sensor wear, calibration and maintenance timers.
Functional reset does not reset these parameters.

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.
