Totalizer functions
SITRANS FC430 has three independent totalizers that can be used for the summation of
massflow, volumeflow, corrected volumeflow, fraction A (volumeflow or massflow) or fraction
B (volumeflow or massflow).
The totalizers can be configured to count balance (net flow), positive flow or negative flow.
In case of failure in the system, the totalizer fail safe mode can be set to:
- Hold: the totalizer holds the last value before the failure occurred
- Run: the totalizer continues counting the actual measured value
- Memory: the totalizer continues counting based on the last input value (for example
massflow) before the failure occurred.
The totalizers can be operated via the Local User Interface or HART (for example SIMATIC
PDM). The totalizers can be reset or preset.

– When this function is activated, it will pause the dosing. When it is deactivated, the
dosing will continue
– Sets the digital output to "Off" and resets the dosing counter
– Starts the automatic zero point adjustment. This function employs the existing
configurations and presumes that the process conditions are prepared for the zero
point adjustment routine
– Resets one of the internal totalizers 1, 2 or 3 (depending on configuration)
