5.3 Connection - Summation

Several instruments can be cascaded to measure also broad con-

veyor belts. The measuring ranges of the instruments must overlap.
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.
The Master instrument must have the function "Mass flow detection".

For this purpose, select under the menu item "

Setup/Application

" the

function "Mass flow detection".
Set the address setting (MGC) on the Master instrument to "0 - 0".
For this purpose, the Slave instruments must be defined as "Slave".

Select under the menu item "

Setup/Application

" the function "Sum-

mation 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.
Connect the instruments according to the following wiring plan:
