Sensors with semiconductor outputs (OSSD, two-channel)

When connecting an OSSD sensor, make sure that pulsed voltage supply is deactivated.

INFORMATION

Deactivate crossfault monitoring at the respective safe inputs of the OSSD-capable sensor technology.
OSSD-capable sensor technology tests and diagnoses the OSSD outputs on its own. The faults detected in the cabling depend on the diagnostic function of the sensor in use.

For OSSD-capable sensors, the following two connection variants result (example):

Variant 1

If contact-equipped sensors are used in addition to sensors with OSSD-capable outputs and if the contact-equipped sensors require crossfault monitoring, the OSSD-capable sensor technology can be supplied via an external voltage supply.

External DC 24 V voltage supply

Variant 2

If only OSSD sensors are used, the voltage can also be supplied via terminals F-SS0 and F-SS1. In this case, deactivate the pulsed sensor voltage supply (F-SS0 and F-SS1) in the "Assist CS.." parameterization tool.

INFORMATION

The performance level that can be achieved is mainly determined by the OSSD sensor technology used.
Use the external voltage supply for sensors that have a higher current consumption than the F-SS.. sensor supply lines can provide.
