Emerson MMI-20019043 Manuel D’Utilisation

The display is able to show a maximum of eight characters, including the decimal point.
For all totalizer values configured as display variables, the position of the decimal point on
the display is fixed to the configured precision of the display variable.

When the totalizer reaches the largest value that can be displayed in these circumstances:

•

The digits roll over.

•

The decimal point does not move.

•

The number of digits on the display does not change.

•

The internal totalizer is reset to 0.

For example, the value 99999.999 rolls over to 00000.000.

If you are not sure whether or not the totalizer value on the display has rolled over, check the value
by using another method to read the current data.

Notes
•

The mass and volume totalizers do not necessarily roll over at the same time.

•

This feature does not apply to inventories. The display presents large inventory values in the
standard manner.

10.1.3

Effect of the Weights & Measures application on process

measurement and outputs

When the Weights & Measures application is installed, process measurement and
reporting is modified to prevent unauthorized use of the data. Specific changes are
controlled by whether the transmitter is secured or unsecured.

mA output behavior

If reporting a flow variable, mA output reports
zero flow. Otherwise, normal.

Frequency output behavior Inactive (produces no pulses), even under fault

conditions
