INP NPN,
slow counting input: the counter
increments the value by one at each volt-
age drop to < 2 V at terminal 5
6
RESET MANUEL ENABLE
Reset key enable input: when terminal 6 is
connected to GND or to 0 V (< 2 V), the
key allows resetting the counter to 0
7
RESET,
Reset input, when terminal 7 is
connected to GND or to 0 V (< 2V), the
counter is reset to 0 (electronic Reset)

is not used with the standard counter
3.3 Function of the front key
Pressing the red front side key resets the counter to
0. This function is only active when input 6 is set to
0 V or connected to GND.
