4-1 Functions 15
SECTION 4: Function
4-1 Functions
Retro-reflective sensors in the E3NT type series are operated with retro-reflectors. The emitted light is polar-
ized. The light is reflected by the retro-reflector and the polarization of the light is changed. The reflected light
is detected by the receiver element, which is integrated in the sensor.
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. Through the optical data interface, the receiver light intensity data can also be transferred
continuously to a PC/ laptop and stored there (data logging).
4-2 Display and operator controls
Operating states are displayed by a 4-digit 7-segment LED display and two LEDs. The sensor can be oper-
ated/set either by push buttons on the sensor or with a PC and setting software (order separately) via an opti-
cal data interface (order separately).
4-2-1 LED display
The light intensity of the received light and the names of the menu levels during set-up of the sensor are dis-
played by the 4-digit 7-segment LED display. The display appears as red digits or letters or green LED bar
chart.
4-2-2 LEDs
The switching status and the stability of the output are signaled by three LEDs. Two of them are visible from
the top and the front of the sensor:
•Yellow LED: ON : Object stably detected
OFF: No object within range
•Red LED: ON: Alarm output on
OFF: normal function

16 SECTION 4: Function
•Status LED – The status LED is only visible from the top of the sensor:
ON: Set-up menu selected
Blinking: Menu level with change
OFF: RUN (normal) mode
4-2-3 Push buttons on the sensor
On the sensor, there are three push buttons for the setting of the sensor:
•Minuskey
• 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. Therefore, all parameters can be set directly on the sensor.
4-2-4 Set-up via a PC
All parameters of the sensor can be set also with a PC (or Laptop) and the OMRON SensorSupportSoftware
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 .
4-3 User set parameters

4-3 User set parameters 17
4-3-2 Output switching
Output switching can be user set jointly for both outputs:
•PNP:
The output is set to plus-switching with open collector.
•NPN:
The output is set to minus-switching with open collector.
• Push-pull:
The output is set to complementary (plus/minus-switching) (factory default).
Refer to 7-3 Connection diagrams.
4-3-3 Function of connector pin 2 and 5
Pin 2 of the connector can be user set as an alarm output or as a test input.
Pin 5 of the connector can be user set as a test input or switched off (factory default).
4-3-4 Switch-on delay
This defines the switch-on response. The time is adjustable between 0 ms and 9999 ms.
• Switch-on delay:
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:
• Switch-off delay:
The switch-off delay starts as from the time when the measured object leaves the sensing zone. The out-
put does not become inactive until the switch-off delay has elapsed.
• Minimum pulse width:
After detection of a measured object, the output remains active for at least the user set switch-off delay. If
the measured object dwells in the sensing zone for longer than the set minimum pulse width, then the out-
put becomes inactive immediately after the object leaves the sensing zone.
• Constant pulse width:
After detection of a measured object, the output only remains active during the user set constant pulse
width and becomes inactive after this time has elapsed, regardless of the measured object's dwell time,
even if the measured object stays in the sensing zone for longer than the user set switch-off delay.

4-3-6 Timing diagrams
4-3-7 Keyboard lock
With the keyboard lock function, the push buttons on the sensor can be locked to prevent inadvertent modifi-
cation of the settings.
The lock can be activated and deactivated on the sensor. When the keyboard lock is active, changes can only
be made after the Minus and Plus keys have been pressed simultaneously for 4 seconds. This tem-
porarily suppresses the keyboard locking. If no key is pressed for about 150 seconds, the keyboard lock is
automatically activated again.
4-3-8 ECO energy saving mode
In the ECO mode, the display switches off automatically approximately 3 minutes after the push buttons have
been pressed for the last time.
The display is activated again the next time the push buttons are pressed. Deactivation of the sensor display
reduces the sensor's current consumption by approximately 20 mA.
4-3-9 Reset
Reset returns the sensor to the factory default settings.
4-4 Inputs/Outputs
In total, the sensor can be operated with a maximum of three inputs/outputs. The functions of the inputs/out-
puts are user determined.
Connector pin 4 is always defined as output (OUT).
Connector pin 2 can be set as alarm output (ALARM), as test input (TEST).
Connector pin 5 can be set as test input (TEST) or OFF.
4-4-1 Input: Test input TEST
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.
