3.5.3 Safety inputs (FDI)
Safe inputs for safety-related sensors
 Max. 4 × 2-channel safety switches and sensors
 Contact based switches, e.g. emergency switches, protective door switches
 Sensors with OSSD switch outputs with test pulses
 Sensors with OSSD switch outputs without test pulses
Error detection/diagnostics:
Internal:
 Device self test: Diagnosis of internal device errors
External:
 Cross connection diagnosis:

The device detects a cross connection between the sensor supplies at the inputs or between one
sensor supply to another potential (if the test pulses are activated)
 Discrepancy diagnosis: for 2-channel inputs
 Short-circuit diagnosis
Parameters
For each input the following types can be selected:
 Safe input for potential free contacts (NC/NC)
 Safe antivalent input for potential free contacts (NC/NO)
 Safe electronic input at OSSD-output with test pulses
