Siemens SITRANS LUT400 - Backup Control (3.3.2.); Remaining Device Life (3.3.3.)

SITRANS LUT400
246 Operating Instructions, 07/2019, A5E33329501-AC
Set parameter to Disabled to stop transducer from measuring while calibration or
maintenance work is performed. Set to Enabled to restart measurements after calibration or
maintenance complete.
Note
•
An Echo Profile (3.2.1.) (Page 241) cannot be requested from LUI when Transducer
Enable (3.3.1.) is set to DISABLED. The local push button will not operate.
•
When Transducer Enable (3.3.1.) is set to DISABLED, the LOE fault will display
immediately.
•
If Transducer Enable (3.3.1.) is set to DISABLED and power to the device is turned off,
Transducer Enable (3.3.1.) will be reset to ENABLED when power is restored.
9.3.3.2 Backup Control (3.3.2.)
LUI only. Determine source of configuration recovery file when sensor has been replaced.
Options
*
DONE
No change required (no fault displayed), or operation is complete
FROM
SENSOR
Sensor parameters will be used as is, and LUI will receive these pa-
rameters as backup.
FROM LUI
Recovery of sensor parameters will come from LUI backup.
When sensor unit has been replaced, fault code 132 is displayed to note that LUI backup file
does not match configuration file in sensor. To clear fault, set Backup Control option to
location from where parameter configuration should be read; from the LUI backup file or from
the new sensor.
9.3.3.3 Remaining Device Life (3.3.3.)
Note
•
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 Life (3.3.4.) (Page 249), Service Schedule (3.3.5.)
(Page 252), and Schedule (3.3.6.) (Page 255).
•
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 or
days (only via SIMATIC PDM, PACTware FDT, and AMS) see Lifetime Expected
(3.3.3.1.) (Page 247).
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 reminders, and
acknowledge them.
The maintenance warnings and reminders are available through HART communications.
