1)
If you are using single-channel safety outputs (Q) for a safety-related application, then a protected or
separate cabling is required for these safety outputs in order to achieve the safety-related characteristics.
Reason: While short-circuits to the supply voltage or cross-circuits to other outputs can be detected, no
other option to switch-off the device exist.
2)
If you are using single-channel or dual-channel safety outputs (Q) without test pulses, then a protected or
separate cabling is required for these safety outputs in order to achieve the safety-related characteristics.
Reason: Short-circuits to the supply voltage or cross-circuits to other outputs are not detected in the
switched-on state without test pulses.
This also applies if an output is used for a non-safety related application. Reason: Even if an internal
hardware error is detected, the switch-off capability of the other safety outputs may be impaired by
reverse currents.
3)
If you are using single-channel/dual-channel safety outputs (Q) without test pulses for a safety-related
application, then one of the following measures is required in order to achieve the safety-related charac‐
teristics:
•
Restart the safety controller once a year.
•
Manually switch off all safety outputs simultaneously for min. 2 s once a year. The supply voltage to
the outputs must be within the operating range during this manual test.
