Function description
TOTALIZERS o TOTALIZER (1...3) o OPERATION
The function descriptions below apply to totalizers 1...3; the totalizers are independently configurable.
SUM
(3040)
Use this function to view the total for the totalizer's measured variable aggregated since
measuring commenced. The value can be positive or negative, depending on the setting
selected in the function “TOTALIZER MODE” (3002), and the direction of flow.
Display:
max. 7-digit floating-point number, including sign and unit
(e.g. 15467.04 m
3
; -4925.631 kg)
! Note!
• The effect of the setting in the “TOTALIZER MODE” function (see page 58) is as
follows:
– If the setting is “BALANCE”, the totalizer balances flow in the positive and negative
directions.
– If the setting is “FORWARD”, the totalizer registers only flow in the positive
direction.
– If the setting is “REVERSE”, the totalizer registers only flow in the negative
direction.
• The totalizer's response to faults is defined in the “FAILSAFE ALL TOTALIZERS”
function (3801), (see page 60).
OVERFLOW
(3041)
Use this function to view the overflow for the totalizer aggregated since measuring
commenced.
Total flow quantity is represented by a floating-point number consisting of max. 7 digits.
You can use this function to view higher numerical values (>9,999,999) as overflows.
The effective quantity is thus the total of OVERFLOW plus the value returned by the
SUM function.
Example:
Reading for 2 overflows: 2 · 10
7
kg (= 20,000,000 kg)
The value displayed in the function SUM = 196,845.7 kg
Effective total quantity = 20,196,845.7 kg
Display:
integer with exponent, including sign and unit, e.g. 2 · 10
7
kg
