High-Performance Distance Sensors
7.3 Locking
If 18 to 30 V DC is continuously applied to the teach-in input, the teach-in key is locked and protected against
inadvertent changes.
1. Change the A1/A2/E3 pin function to external teach-in.
2. Permanently connect pin A1/A2/E3 to voltage within a range of 18 to 30 V DC.
3. The sensor is protected against inadvertent changes caused by the teach-in key.
7.4 Switchable Emitted Light
Emitted light from the sensor can be switched off by means of an IO-Link parameter. Beyond this, the sen-
sors’ inputs can be programmed via IO-Link so that the “switchable emitted light” function can also be activat-
ed by applying 24 V to the respective input.
7.5 External Teach-In
Teach in output A1/A2 via the teach-in input.
1. Set the pin function for I/O1 or I/O2 to external teach-in input using IO-Link or wTeach.
2. Connect the pin selected for use as an input to 24 V in order to teach-in switching output 1 (2 sec.) and
switching output 2 (5 sec.).
3. As soon as voltage drops at the input, the outputs are taught in.
NOTE!
Please note that during external teach-in via one of the two configurable output pins, both
independent switching points are stored to the sensor and can be read out at any time via
the process data using IO-Link. If both outputs need to be evaluated via the pins, the previ-
ously configured teach-in input must be configured once again as an output.
If the La function (switchable emitted light) is not needed, pin 5 (I3 pin function) can also be
used as a teach-in input, in order to teach-in switching outputs O1 and O2 using the proce-
dure described in point 2.
7.6 Error output
The error output is switched in the following cases:
• Signal from object too weak
• Incorrect installation
• The object is located outside of the working range.
