Figure 29: Connection 1 × Interlock Monitoring, Dual Channel, Antivalent Pre-Evaluation
To monitor protective door devices, you can connect the normally open contacts
of a safety interlock switch to four digital inputs of the F I/O module.
Use the WAGO parameterization tool to set the parameters.
Set the Pre-Evaluation parameter for the digital inputs used to "Antivalent." To
have the signal lines of the digital inputs of the F I/O module monitored for short
circuits, set the Short Circuit Test parameter for all inputs to "Activated." In
addition, set the Discrepancy Time parameter to the discrepancy time required
for the normally open contact of the safety interlock switch.
With this wiring, you can achieve a risk reduction of SIL3/Cat.4/PL e.
