3.4.8 External resistor for OSSD outputs
To guarantee the correct connection between the OSSDs of the control unit and an external device, it may be
necessary to add an external resistor.
If the pulse width set (OSSD Pulse width) is 300 μs, it is strongly recommended to add an external resistor to
guarantee the discharge time of the capacitive load. If it is set at 2 ms, an external resistance must be added if
the resistor of the external load is greater than the maximum resistive load allowed (see "Technical data" on
page105).
Below are some standard values for the external resistor:

3.5 Sensors
3.5.1 5 meters range sensors
These are the main characteristics of the sensors:
NOTICE: the sensors connected to the control unit must all be of the same type (e.g., all 5 meters range sensors or
all 9 meters range sensors).
