14.11 Dual Channel Totalizer (TOTALIZER)
This module allows separate summarizing of total amount of flow from up to 2 digital pulse counter
inputs. By means of configuration file the totalizer can be reduced from dual channel to single channel.
These modules are explained
below.
Figure 73: TOTALIZER
Totalizer 1, 2
Each of the both totalizers has a main and a daily totalizer. The detected amount of the process value
is summed up in the totalizer corresponding to the configured K-Factor of the pulse counter input and
the parameterized unit of the totalizer.
If the counted volume in the parameterized unit is to large for displaying (Volume >= 1000000 units),
its value is converted into a larger unit for displaying. Each totalizer can count / display max.
999999 m³. If more volume is counted, the totalizer begins to count and display from 0 in the
parameterized unit.
Each Totalizer 1, 2 can be reset independently in the configuration menu - main and daily totalizer are
reset at the same time. The reset is done when returning to the main menu. So both totalizators can
be reset at the same time, if required.
The daily totalizers can be reset independently with code level Operator in the menu Processdata and
in the corresponding Parameter menu.
For displaying purposes the current flow rate of each module input is calculated from the amount of
incoming pulses per second and displayed in the module specific process data menu in a configurable
unit.
Override
The activity of the module TOTALIZER can be influenced by certain states (see figure). If the system
switch override function or the flow switch override function is enabled for this module and the
corresponding system switch / flow switch function is active, incoming pulses will be ignored and both
totalizers will not be incremented.
The value of the main and the daily totalizer are stored every 10 minutes in a non-volatile
memory.
