Level 4 - Totalization
In level 4, it is configured the totalization of the process variables of the first 8
channels with linear input. When the totalization of a certain channel is enabled, the
indicator shows the value of the process variable and its totalization in the operation
level. If the totalization is disabled its value is not shown.
The integration is performed according to the percentage of the input signal in
relation to the range limited by the parameters Eng Low and Eng High configured for
the channel. In order to determine the totalization of a signal, it is necessary to
provide the parameters corresponding to the counts CONT which results from the
integration of an input signal of 100% FS of the choosen channel (whose indication is
given by Eng High) within an interval of time configured by TIME, given in minutes.
The decimal point for the totalization is configured in the DC.PT option.
The table below refers to the ranges of the parameters shown in figure 18.
Mnemonic
Counts added to the totalization after an
CONT interval of time (TIME), when there is a
TIME totalization is increased by CONT, when
there is a signal of 100% FS in the input.
