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.

[2] | 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.
