3.1.2.2 Reaction in the Event of a Fault
If the device detects a faulty signal on a digital output, the affected module output is set to the
safe (de-energized) state using the safety switches.
If a device fault occurs, all digital outputs are switched off.
In both cases, the devices activates the FAULT LED.
The error code allows the user to configure additional fault reactions in the user program.
3.1.3 Pulsed Outputs
The 2 digital pulsed outputs can be used to detect short-circuits and open-circuits on digital
inputs, e.g., on EMERGENCY STOP button complying with Cat. 4 and PL e in accordance with
EN ISO 13849-1.
i
Pulsed outputs must not be used as safety-related outputs (e.g., for activating safety-related
actuators)!
