Function group
DISPLAY
TOTAL VOLUME
Display of the totalised flow quantity from when measurement began.
This value is either positive or negative depending on the direction of flow.
Notes!
•
If the count has more figures than can be displayed, e.g. with overflow,
then the symbol “>” is shown before the value.
•
If the function “MEASURING MODE” is set to “UNIDIRECTIONAL”
(see page 75), then the totaliser only registers flow in the positive direction.
•
In cases of error the totaliser is coupled to the error response of the
pulse/frequency output (see page 57, 85). For transmitters with an RS 485
communications module, this is only the case if the function “SYSTEM
CONFIG.” is set to “AUX.INPUT/FREQ.” or “RS485 / FREQ.” (see page 71).
With the setting “........../CURRENT”, the totalizer always stops totalizing in
case of a failure.

TOTAL
OVERFLOW
Display of totalizer overflows.
On the display the totalised flow is shown as a max. 7-digit number with
floating decimal point. Larger numbers (>9,999,999) can be read off in this
function as overflows. The effective amount is thus the sum of the overflow and
the value shown in the HOME position resp. in the function “TOTAL VOLUME”.
Example:
Display of 2 overruns:
2 e7 dm
3
= 2
⋅
10
7
dm
3
= 20,000,000 dm
3
The actual displayed totalizer value is 196,845.7 dm
3
.
Total amount since measurement started = 20,196,845.7 dm
3
Note!
•
This function is displayed only if overruns have occurred. In addition, in the
HOME position an overflow is made visible by optically inverting the “>” sign.
•
The totalizer value may have a positive or negative sign as a result
of the bidirectional measurement.
7
Display of the actual totalizer value (HOME position).
