Operating notes
Safety outputs Q1 and Q2
If the connected Safeguard Detector sensors do not generate a 10 Hz signal, safety out‐
puts Q1/Q2 switch off within the response time. For example, this is the case if the sen‐
sors do not detect any object or if there is a sensor error.
Application diagnostic output Q3 “reset required”
The application diagnostic output Q3 indicates the status
reset required
. Depending on
the configuration, a signal lamp or higher-level control can be connected to this output.
Input I2 is used for configuring output Q3.
