2-wire AC/DC
• AC mode: the device has reverse polarity protection.
• DC mode: in the event of reverse polarity the maximum safety mode is always
detected. Check the wiring and perform a function check before commissioning.
The device is not damaged in the event of reverse polarity.
3-wire DC-PNP
Integrated. In the event of reverse polarity, the device is deactivated automatically.
2-wire AC/DC
During switching the sensor checks whether a load, e.g. relay or contactor, is
present (load check). If an error occurs, the sensor is not damaged.
Smart monitoring: normal operation is resumed once the error is fixed.
3-wire DC-PNP
Overload protection/short-circuit protection at I > 250 mA; the sensor is not
destroyed.
Intelligent monitoring: Testing for overload at intervals of approx. 1.5 s; normal
operation resumes once the overload/short-circuit has been rectified.
