4.3 Functions and operating modes
4.3.1 Safety Function
The TBPN-L5-4FDI-4FDX provides four safe digital SIL3 inputs (FDI) and four SIL3-connectors
(FDX), configurable as inputs or outputs.
The following devices can be connected to the safety inputs:
n
1- and 2-channel safety switches and sensors
n
Contact based switches, e.g. emergency switches, protective door switches
n Sensors with OSSD switching outputs
n
Antivalently switching OSSD sensors
The four safe SIL3 outputs can be used PP- or PM-switching.
Safe status
In the safe state the device outputs are in LOW-state (0). The inputs report a LOW-state (0) to
the logic.
Fatal error
n Incorrect wiring at the output (i.e. capacitive load, energetic recovery)
n
Short-circuit at the line control output T2
n
Incorrect power supply
n
Strong EMC disturbances
n
Internal device error
4.3.2 Safety inputs (FDI)
The safe inputs are suitable for the connection of safety-related sensors:
n
Max. eight 2-channel safety switches and sensors
n
Contact based switches, e.g. emergency switches, protective door switches
n
Sensors with OSSD switch outputs with test pulses
n
Sensors with OSSD switch outputs without test pulses
Error detection and diagnostics
Internal:
n
Device self test: Diagnosis of internal device errors
External:
n Cross connection diagnosis: The device detects a cross connection between the sensor sup-
plies at the inputs or between one sensor supply to another potential (if the test pulses are
activated)
n Discrepancy diagnosis: for 2-channel inputs
n
Short-circuit diagnosis
Parameters
For each input the following types can be selected:
n
Safe input for potential free contacts (NC/NC)
n
Safe antivalent input for potential free contacts (NC/NO)
n
Safe electronic input at OSSD-output with test pulses
