The main application area of the FM 450-1 is where signals with high fre-
quencies are counted and high-speed responses have to be triggered to prede-
fined counter statuses.
Examples include:
Packaging plants
Sorting plants
Dosing or proportioning plants.
In this example, a carton must be filled with a specific number of parts. One
counter of the FM 450-1 counts the parts and controls the motor for trans-
porting the parts and the motor for transporting the carton.
If the carton is in the correct position, conveyor belt A is stopped via the light
barrier, the count is started and the motor for conveyor belt B is switched on.
When the carton contains the programmed number of parts, the FM 450-1
stops the motor for conveyor belt B and switches on the motor for conveyor
belt A for removal of the carton. The count can start again when the next
carton reaches the light barrier.
