Sensors with semiconductor outputs (OSSD, two-channel)

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

INFORMATION

Deactivate line diagnostics 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 errors 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 line diagnostics 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 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 achievable performance level 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.
