The diffuse reflective sensors belonging to the E3NT type series may only be used as described in these operating instructions. They may only be operated as part of a higher-level overall system, e.g. a machine installation. During machine planning and the use of diffuse reflective sensors belonging to the E3NT type series, the safety and accident prevention regulations that are specific to use must be observed, e.g.:...

The distance is evaluated in accordance with the double triangulation principle. In this case, the distance from the measured object is determined not only via the intensity of the reflected emitted light, but also via the angle between the emitter, the measured object and the receiver.

Due to the infrared emitted light and the very low minimum reflection factor of 6 %, objects can be detected largely independently of their colour and their surface finish. The sensor can be user set by push button on the unit or with a PC and the SensorSupportSoftware S (order separately) via an optical data interface E3NT-AL232 (order separately).
Operating states are displayed by a 4-digit 7-segment LED display and two LEDs. The sensor can be operated/set either by push buttons on the sensor or with a PC and setting software (order separately) via an optical data interface (order separately).
Section 4-3 User set parameters 4-2-3 Push buttons on the sensor On the sensor, there are three push buttons for the setting of the sensor (see Figure 3 Operator controls and displays) : • Minus key • Plus key • Enter key With these three push buttons, the operator moves through the sensor's menu and sets the parameters in accordance with the application.
The diffuse reflective sensor can be operated in the following modes: • Background suppression BGS (factory default) Measured objects are detected as from the blind zone up to the user set or teached switching point S . Objects in the background, behind the user set switching point, are ignored.
In the window evaluation mode, two switching points must be defined for each output. In the FGS or BGS mode, only one switching point needs to be defined for each output. 4-3-4 Output switching Output switching can be user set jointly for both outputs: •...
Function of connector pin 2 Pin 2 of the connector can be user set as Output 2 (OUT 2), as an alarm out- put, as a teaching input for switching points A and B, as a test input or as a trigger input.
The distance between the sensor and the measured object is displayed as a green bar chart. 4-3-10 Keyboard lock With the keyboard lock function, the push buttons on the sensor can be locked to prevent inadvertent modification of the settings. The lock can be activated and deactivated on the sensor.
Connector pins 2 and 5 can be set as teaching inputs for the switching points A to D. If a signal in the operating voltage range is applied to this input, the sensor is taught the switching point A, B, C or D depending on the user set preferences.
4, fixed) and OUT 2 (Connector pin 2) switch in accordance with the sensor's settings. 4-4-2-2 Alarm output ALARM Connector pin 2 can be set as the alarm output. The alarm output is switched on if the intensity of reflected light is too low or no measured object is detected.

E39-EL1 Applying the adapter bracket E39-EL2 the universal mounting bracket E39- EL1 can be used as an adapter plate to mount the E3NT to existing holes. 1. Mount the bracket E39-EL1 to the existing assembly holes on the machine, if necessary produce additional ones.
Conversions and changes and tampering in the interior of the sensor, the data interface and the alignment tool are forbidden. A technical data of the supply voltage and of the input/output wires must conform to the technical data of the sensor (see sensor rating plate and SECTION 3 Specification).
The sensor is factory set to a PNP output. The output circuit is resistant to short-circuits and reversed power supply. When use is made of the PNP or NPN output circuit, the output circuit that is not selected is deactivated.
Input circuits The sensor inputs are realised in positive logic and detect a positive voltage level of more than 1 ms duration as a valid signal if the voltage level is between 10 V and the power supply voltage. E3NT...

They may only be operated as part of a higher-level overall system, e.g. of a machine installation. Diffuse reflective sensors in the E3NT type series must not be used as safety components within the scope of the EU machine guideline.
Hence the sensor must be aligned relative to the optical axis. The alignment marking on the top of the sensor can be used as a sighting line for the optical axis, thus simplifying alignment (see Figure 1 Aligning the sensor) .
For each output of the sensor (up to two), up to two switching points can be user set. Only one switching point is active in the foreground and background suppres- sion modes.
The sensor is set by means of three push buttons. With these push buttons, the user navigates through the setting menus, through which all necessary sensor settings can be made. If no keys are pressed for 2 minutes during set-up, the sensor returns automatically to run mode. 9-1-1...
