MINITRAC 31 • Foundation Fieldbus

41782-EN-131119

The MINITRAC 31 requires this information for the decay compensa-

tion. An annual recalibration is hence not necessary.
Enter the requested parameters via the appropriate keys, save your

settings with [OK] and jump to the next menu item with the [ESC] and

the [->] key.

Enter here, the respective application.
This menu item enables adaptation of the sensor to the requested ap-

plication. You can choose between the following applications: "Level",

"Density", "Limit level", "X-ray alarm" or "Real value correction".

With this menu item you safeguard the sensor parameters against

unauthorized or unintentional modifications.
This menu item is described in the operating instructions manual

"Display and adjustment module".

6.7 Parameter adjustment/Real value correction

To correct a level measurement, a real value correction can be carried

out when a certain level is reached. This is for example necessary in

case of recurring buildup on the vessel wall.
The level measurement can thus be reset to the correct real value.
The level measuring instrument acts as Master and the MINITRAC 31

operates as Slave.
First of all, define the function of the Slave instrument before you

define the Master instrument. The Master instrument can thus imme-

diately recognize the connected Slave.
For this purpose, the Slave instrument must be defined as "Real value

correction". Select under the menu item "Setup/Application" the func-

tion "Real value correction".
You can set the address (MGC) on the Slave instrument at will. Only

the address "0 - 0" is reserved for the Master instrument.
The Master instrument must have the function "Level". For this

purpose, select under the menu item "Setup/Application" the function

"Level".
Set the address setting (MGC) on the Master instrument to "0 - 0".

You have to enter the address of the Slave instrument in the list of

the Master instrument. This function is not possible in the display and

adjustment module. To do this you need PACTware with the respective

DTM.
