Main counting direction forward
•
The counter counts starting with the load value.
•
When the counter reaches the end value –1 in positive direction, it
jumps to the load value at the next positive count pulse and the gate is
automatically closed.
•
To restart the count process, you must create an edge 0-1 of the gate.
The counter starts with the load value.

Main counting direction backwards
•
The counter counts backwards starting with the load value.
•
When the counter reaches the end value +1 in negative direction, it
jumps to the load value at the next negative count pulse and the gate is
automatically closed.
•
To restart the count process, you must create an edge 0-1 of the gate.
The counter starts with the load value.
