5.7.6 Signal analysis
Settings only required if the inputs combined in groups are to be analysed
automatically.
The analyses can be displayed in normal operation at the touch of a button ("Main menu
- Analysis").
This information is also saved (reduces the memory available for the graphics),
transferred to a PC and can be used there for further analyses.
Fig. 30: Set-up, Signal analysis
Intermed analysis: Determines quantities in the time intervals defined here.
Day: Determines daily quantities of all channels allocated in groups on daily change.
Month: Determines monthly quantities of all channels allocated in groups on monthly
change.
Year: "Yes": determines annual quantities of all channels allocated in groups on year
change.
"No": alternative for the annual analysis function: the quantities are determined
continuously. Begins after resetting, as further described below (e.g. for
totalizers).
Adv. analyses: In addition to the current and last analysis, further historic analyses can be
displayed at the unit, e.g. the last 7 intermediate analyses, 7 daily analyses, 7
monthly analyses, 7 annual analyses
Exp. statistic: Yes: The device can run advanced statistic analyses (e.g. run time distribution,
cumulated quantities, number of switch sequences...).
Synchron. time: Time at which signal analyses are completed. Example of daily analysis: the
daily analysis is completed at the set time, i.e. it contains the analysis of the
measured values over the last 24 hours.
Reset to zero: The analyses are reset directly at the device with this function (e.g. reset after
completing the commissioning of a system)

Note!
All previous (commissioning) signals are discarded.
The graphics/storage are, however, not affected if you leave the set-up and
answer the "Accept set up?" question with "No" (reference).
If you answer the question with "Yes", the contents of the memory and thereby
the graphic display is also deleted/reset.
If the previous signals are still required, save them on a diskette before
resetting (see Section "Commissioning - Accessible functions - Diskette").
The reset takes effect immediately if you confirm here with "E= Accept".
