Explanation:
When facing the control panel, the Total counter will be shown using the LED as follows. The
constant light indicates which LED that is about to flash. The Total counter will start from the right
and move to the left. Example, if the machine has collated 213000 covers it will be shown as:
the right LED will flash 3 times, the middle LED will flash 1 time and the left LED will flash 2
times.
