Function description
Procedure
1. Select the button for the feedback signal.
2. Select the signal that matches your particular application.
You have interconnected the "STO active" checkback signal.
❒
After STO has been selected, the converter signals "STO active" to the higher-level control.

Setting the filter for fail-safe digital inputs

Overview
The following filters are available for the fail-safe digital inputs:
• A filter for the simultaneity monitoring
• A filter for suppressing short signals, e.g. test pulses.
Function description
Discrepancy time for the simultaneity monitoring
The converter checks that the two input signals of the fail-safe digital input always have the
same signal state (high or low).
With electromechanical sensors (e.g. emergency stop buttons or door switches), the two
sensor contacts never switch at exactly the same time and are therefore temporarily
inconsistent (discrepancy). A permanent discrepancy signifies a fault in the fail-safe digital
input circuit, e.g. wire breakage.
