Data logging
The SITRANS LUT400 provides an extensive logging feature which can be viewed on the
local display or downloaded to a PC via USB using the Web Browser tool.
Enable data logging for a Process Value, an Alarm, or for Flow (see
For flow, the logging rate can be fixed or variable. The latter being useful in conserving
logging space. The condition for variable logging is determined when selecting the
logging rate.
Variable logging rate conditions are categorized as: percent change of flow per minute,
percent change of maximum flow or percent change of maximum head. Logging occurs at
the normal (slower) rate while the condition is less than the setpoint (
). If the condition exceeds the rapid flow log setpoint, the rapid rate of logging
takes effect until the condition falls below the standard flow log setpoint (
The setpoints represent the absolute value of the rate of change; that is, for either
increasing or decreasing flowrate. The SITRANS LUT400 does not recognize negative
entries for standard or rapid flow log setpoints.
Flow data is logged in flowrate units (with full resolution of flow measurement value)
from 0 to 110% of maximum flow. Flows above 110% are logged at the 110% value (in
flowrate units). Truncation of flows to 110% does not apply to daily totalization.
Viewing the Data Log
To view the data log, navigate to
3. Maintenance and Diagnostics

and select the desired log; Alarms, OCM, PV, or Daily Totals.
The logs can be examined locally via LUI or uploaded to a PC via USB using the Web
Browser tool.
LUI logs are viewed by choosing the desired log (Alarm, OCM, Daily Totals, or Primary
Variable PV) in 3.2.6.x, and then scroll through the entries using the 'up' and 'down' arrow
keys. The most-recent log entry is the initial display. Pressing the 'up' arrow will scroll
back in time showing the previous entries.
