Sensors with semiconductor outputs (OSSD, 2-channel)

When connecting an OSSD sensor, make sure that line diagnostics 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 sensors with contacts are used in addition to sensors with OSSD-capable outputs and if crossfault monitoring must be used for th sensors with contacts, the OSSD-capable sensor can be supplied via an external voltage supply.

External DC 24 V voltage supply

Variant 2

If only OSSD sensor technology is used, the voltage can also be supplied via terminal F-SS0. In this case, deactivate the pulsed sensor voltage supply (F-SS0) in the "Assist CS.." parameterization tool.

INFORMATION

The achievable performance level is mainly determined by the OSSD sensor technology used.
Use the external voltage supply for sensors whose current consumption is too high for the F-SS0 sensor supply.
