6.4 Parameter adjustment - Summation Slave
To measure the level in very high vessels, multiple instruments can be
cascaded.
Cascading means that two or several instruments are connected
which can together cover a longer measuring range.
The instrument acts as Master and all other instruments operate as
Slaves.
The pulse rates of all instruments are summed in the Master instru-
ment and converted into a common signal.
First of all, define the function of the Slave instruments before you
define the Master instrument. The Master instrument can thus imme-
diately recognize the connected Slaves.
For this, the Slave instruments must be defined as "Summation
Slave". Select under the menu item "Setup/Application" the function
"Summation Slave".
The address setting (MGC) on the Slave instruments can be freely
selected. Only the address "0 - 0" is reserved for the Master instru-
ment.
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 addresses of the Slave instruments in the list of
the Master instrument. This function is not possible in the supply and
adjustment module. To do this you need PACTware with the respective
DTM.
The main menu is divided into five sections with the following func-
