Totalizer overflow
The overflow behavior of the totalizers can be set:
• Select
Special Funct.\SYSTEM settings\Measuring\Quant. wrapping
.
• Select
on
to work with overflow.
The flow totalizer will be reset to zero automatically when ±9999999999 is reached.
• Select
off
to work without overflow.
The value of the totalizer increases to the internal limit of 10
38
. The values will be displayed as exponential numbers
(±1.00000E10), if necessary. The flow totalizer can only be reset to zero manually.
• Press ENTER.
Independent of the setting, the flow totalizers can be reset to zero manually.

Notice!
The overflow of a totalizer influences all output channels, e.g., data logger, online transmission of data.
The output sum of both totalizers (throughput
Q
) transmitted via an output is not valid after the first overflow (wrap
-
ping) of one of the totalizers.
In order to signalize the overflow of a totalizer, an alarm output with the switching condition
QUANT.
and the type
HOLD
has to be activated.
