8-2-2-1-4Off-switching mode
The nature and the numeric value of the output's switching response are set
in the Off-switching mode box. This parameter can be set separately for
both outputs.
The timing response described here is referred to the Light-on switch-
ing inversion.
The behaviour of the individual off delay modes is inverted in the Dark-on switching inversion mode.
The nature of the off-switching response is chosen in checkboxes:
Off delay
The off delay starts as from the time when the measured object
leaves the sensing zone. The output does not become inactive until
the off delay has elapsed.
Minimum pulse width
After detection of a measured object, the output remains active for
at least the setted off delay. If the measured object dwells in the
sensing zone for longer than the setted off delay, the output
becomes inactive immediately after the object leaves the sensing
zone.
Constant pulse width (one shot)
After detection of a measured object, the output only remains active
for the setted off delay and becomes inactive after this time has
elapsed, regardless of the object's dwell time, even if the measured
object dwells in the sensing zone for longer than the setted off delay.
Minimum pulse width and Constant pulse width are not activatable,
if On delay is activated.
The time can be set in several ways:
• By slider
The position of the slider can be varied with the mouse. The resulting set
time is displayed as a number next to the slider.
The number can be increased or reduced with the Increment and Decrement buttons of the slider.
• With number input
The time can also be entered directly as a number. The slider is adjusted
accordingly.

8-2-2-3-1Pin assignments
The functions of Connector pin 2 and Connector pin 5 are set in the Pin
Assignment box.
In total, the sensor can be operated with a maximum of three inputs/outputs,
and a maximum of two outputs is possible at the same time.
The functions of the inputs/outputs can be set in the following order:
Connector pin 4 is always defined as Output 1 (OUT1) and cannot be modi-
fied.
Connector pin 2 can be set as Switching output 2 (OUT2), teaching input
(TEACH) for the switching points A and C or as the test input (TEST) or trigger input (TRIG).
Connector pin 5 can be set as the trigger input (TRIG), teaching input
(TEACH) for the switching points A to D or as the test input (TEST).
• Teaching input TEACH
If a signal in the operating voltage range (at least 10 V) is applied to this
input, the switching point A, B, C or D is teached, depending on the settings, and analogously to the Teach buttons (see Section 8-2-1-1 Teachingswitching points).
• Test input TEST
The emitter is deactivated if a signal in the operating voltage range (at
least 10 V) is applied to this input.
If the sensor is in the light-on state, the receiver detects the absence of
the emitted light reflected by the measured object, regardless of the setted switching points.
The output state changes.
This function can be used to test correct functioning of the sensor.
• Trigger input TRIG
If a signal in the operating voltage range is applied to this input, the sensor is requested to start a measurement (object distance).
The sensor rate (response time) can be increased by the trigger function.
• Switching outputs OUT1 and OUT2
The switching outputs switch when a measured object is detected and in
accordance with the sensor's settings.

sensing zone for longer than the setted off delay, the output
becomes inactive immediately after the object leaves the sensing
zone.
Constant pulse width (one shot)
After detection of a measured object, the output only remains active
for the setted off delay and becomes inactive after this time has
elapsed, regardless of the object's dwell time, even if the measured
object dwells in the sensing zone for longer than the setted off delay.
Minimum pulse width and Constant pulse width cannot be activated, if On delay is activated.
The time can be set in several ways:
• By slider
The position of the slider can be varied by dragging with the mouse. The
resulting set time is displayed as a number next to the slider.
The number can be increased or reduced with the Increment and Decrement buttons of the slider.
• With number input
The time can also be entered directly as a number. The slider is adjusted
accordingly.

8-5-1-2-1Pin assignments
The functions of Connector pin 2 and Connector pin 5 are set in the Pin
Assignment box.
In total, the sensor can be operated with a maximum of three inputs/outputs,
and a maximum of two outputs is possible at the same time.
The functions of the inputs/outputs can be set in the following order:
Connector pin 4 is always defined as Output 1 (OUT1) and cannot be modi-
fied.
Connector pin 2 can be set as test input (TEST) or alarm output
(ALARM).
Connector pin 5 can be set as the test input (TEST) or deactivated.
• Test input TEST
The emitter is deactivated if a signal in the operating voltage range (at
least 10 V) is applied to this input.
If the sensor is in the light-on state, the receiver detects the absence of
the emitted light reflected by the measured object.
The output state changes.

This function can be used to test correct functioning of the sensor.
• Alarm output ALARM
The outputs switch when a the sensor works in an unstable mode due to
dirt on the window or other critical detection conditions (e.g. steamy and
foggy environment).
8-5-1-2-2Output mode
The output circuit is set in the Output mode box. The output circuit can be set
jointly for both outputs:
The sensor is set by default to the push-pull output (complementary). In this
output setting, both output transistors are alternately active.
When the output circuit is set to PNP or NPN, the relevant output circuit that is
currently not in use is switched off.
Both output circuits are resistant to short-circuits and are polarity-safe.

When this checkbox is marked, the display on the sensor's display is
rotated by 180°.
This function may be useful when the sensor if fitted in certain positions.
8-5-2-2-2Economy mode
• Economy mode checkbox
When this checkbox is marked, the sensor's display mode is set to the
energy saving mode.
In the energy saving mode, the display switches off automatically approximately 5 minutes after the last time a push button has been pressed on
the sensor.
8-5-2-3Locking of sensor
The following locking modes are available for selection in the pulldown menu
of this box:
• No locking
The sensor is not locked. It can be set by push button and PC. The display on the sensor is active.
• Keylock
With the key lock function, the push buttons on the sensor can be locked
to prevent unintentional changing of the settings.
The lock can be switched on and off on the sensor.
When the key lock is active, changes can only be made after the Minus
and Plus buttons are pressed simultaneously for 4 seconds. This temporarily suppresses the key lock. If no buttons are pressed for about 5 minutes, the key lock is automatically activated again.
• Complete sensor locking
The sensor is completely locked. It cannot be set by push buttons and
PC. When a button is pressed, the display always stays in the normal
mode (analog value display/bar graph).
8-5-2-4Heating (only available for E3NT-RH@@)
The following window heating modes are available for selection in the pulldown menu of this box.
• Heating off
The sensor window heating is switched off.
• Heating on
