• The counter counts once starting with the load value.
• You may count forward and backwards.
• The count limits are set to the maximum count range.
• At over- or underrun at the count limits, the counter jumps to the
according other count limit and counts from there on. The gate is
automatically closed.
• To restart the count process, you must create a positive edge of the
gate.
• At interrupting gate control, the count process continuous with the last

• At aborting gate control, the counter starts with the load value.
