Sums (totalizers)
Two resettable and two non-resettable totalizers (grand totalizers) are available for mass, heat or
corrected volume flow. The grand totalizer is marked by "Σ" in the display element picklist. (Menu
item: Setup (all parameters) Æ Display Æ Group 1... Æ Value 1... Æ Σ Heat sum ....
Sum overflows are recorded in the event buffer (menu item: Display/Event buffer). The totalizers
can also be displayed as an exponential value to avoid overflow (Setup: Display Æ No. of sums).
The totalizers are configured in the submenu Setup (all parameters) Æ Applications Æ
Applications ... Æ Sums. The totalizers can also be reset to zero by signal (e.g. after remotely
reading the totalizers via PROFIBUS).
!
Note!
In the Setup "Navigator Æ Counter val", all the totalizers are listed and can be read out and, if
necessary, reset to zero individually or all together.
