Retro-reflective sensors belonging to the E3NT type series must not be used as safety components within the scope of the EU Machine guidelines. Their use in applications in which the safety of persons depends on functioning of the sensor is not permissible! The manufacturer and owner of the higher-level overall system, e.g.

If the light spot is not completely interrupted by the object, the object may not be detected correctly. The sensor can be user set by push button on the unit or with a PC and the SensorSupportSoftware S3 via an optical data interface E3NT-AL232 (order separately). The optical data interface operates with an IR com- munication element.
S3. The connection between the sensor and the PC is established via an optical data interface (E3NT-AL232 2m). The data interface is connected to a free COM port of a PC/laptop. Also the USB – RS232 Converter of OMRON can be used to realize the connection. Refer to the separate operating instructions ABBO0018 for further information on setting with a PC and the SensorSupportSoftware S3 .
The switch-on delay starts as from the time when the measured object enters the sensing zone. The out- put does not become active until the switch-on delay has elapsed. 4-3-5 Switch-off responses This defines the switch-off response. The time is adjustable between 0 ms and 9999 ms. There are 3 different kind of responses possible: •...
Connector pins 2 or 5 can be set as test input. The emitter is deactivated if a signal in the operating voltage range is applied to this input. Depending on the absence of a detection object the sensor alters it's output,because no light is emitted.
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 from the reflector is too low. In this case, the sensor may be covered with dust. Please clean the sensor and check the alarm output again.
As far as possible, the sensor's optical surface should be aligned parallel to the surface of the retro-reflector. 90˚ If the detection object has a glossy, reflecting surface, the object should be tilted by 5° … 10° in relation to the surface of the light beam of the sensor.
If there is a reflecting surface in parallel with the sensor's optical axis, this might lead to unstable switch- ing states. Therefore, reflecting objects within the sensor's optical axis should be avoided. If this should not be possible, the reflecting surface should not be parallel to the sensor's optical axis, but should be rotated by about 10°.
Conversions and changes and tampering in the interior of the sensor, the data interface and the align- ment 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).
Out1 Out2 • When use is made of the PNP or NPN output circuit, the output circuit which has not been selected is deactivated. • When used as a complementary output, NPN or PNP outputs act in antiphase as the switch state changes.
• Professionally connect the cable shield to the control cabinet housing (flat surface, conductive). • Professionally connect wires of cables or free cable ends that are not used to the cable shield on both ends of the cable. • If the control cabinet is connected by means of connectors, use connectors with a metal housing and a leading protective earth contact (in accordance with EN 60204-1) only.
For alignment over long distances, the laser alignment aid (E3NT-AP1) can be used (order separately). This alignment aid can be clicked on top of the sensor and a visible laser beam gives a hint of the direction of the sensor.
SECTION 9: Configuration 9-1 Setting the sensor using the push buttons 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.
Enter 2s Remarks 1. If the delay-function is set to „off“ in the OPTIONS menu path, the switch-on/off delay parameters do not appear in the SET menu path. 2. The On-delay-setting and the Off-delay-setting are only available if the switch-on/off delay in the OPTIONS menu path is set to “on-1”.
Remarks 1. If the ECO energy saving mode is on, the display is switched off if no keys are pressed for about 3 min- utes. The display is switched on again when any key is pressed. 2. The different modes for the switching output delay are described in chapter 4-3-4 Switch-on delay...
PC is established via an optical data interface (E3NT-AL232 2m). The data interface is clipped onto the sensor and should be connected to a free COM port on the PC/laptop via the interface cable.
The sensor, the optical data interface and the alignment tool may only be repaired by the manufacturer. Send in the sensor and the optical data interface tool to the supplier for repair along with a description of the fault. 10-1 Maintenance...
