Using the operating instructions

1-1 Using the operating instructions

These operating instructions refer exclusively to diffuse reflective sensors in
the E3NT type series. They contain the most important notes for operating the
sensor in line with safety requirements.

The operating instructions must always be close at hand and accessible at all
times, and must be kept together with the higher-level machine installation.

The contents of these operating instructions must be read and understood,
and all its points must be followed by everyone who is responsible for machine
planning, assembly and operation. This particularly applies to the safety
notes.

Observance of the safety notes will help to avoid accidents, malfunctions and
faults.

1-2 Use in accordance with the intended purpose

Diffuse reflective sensors in the E3NT type series are always operated as part
of a higher-level overall system, e.g. a machine installation.

They may only be used as optical sensors to check the presence of objects
within a machine installation with a higher-level control system.

Any other use, or any use exceeding this scope, is not permitted.

Section 2-1

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.:

•EN 292, Safety of machines, general design principles

•EN 60204, Electrical equipment of machines

Diffuse 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. of
a machine installation, is responsible for conformity with the national
and international safety and accident prevention regulations that apply
to the special application.

Assembly, electrical connection and maintenance may only be carried
out by instructed, trained and authorised specialist personnel in
accordance with applicable regulations after de-energising the power
supply and switching off the machine.

The machine must be safeguarded against reactivation.

Conversions and changes as well as tampering with the interior of the
sensor, the data link and the alignment tool are forbidden.

The notes contained in these operating instructions, in particular the
chapters entitled Safety notes and Maintenance and repair, must be
integrated into the operating instructions of the higher-level overall sys­tem.

4-1 Functions

Section 4-1

Diffuse reflective sensors in the E3NT type series can be operated with back­ground and foreground suppression. Genuine window evaluation can also be
set. 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.

Contrary to sensors with single triangulation, E3NT with double trian­gulation, allows measured object's direction of motion to be in all three
directions. Thus, the rotatory position of the sensor about its optical
axis can be chosen freely

(see Figure 1 Position of the sensor)

Measured objects are detected only within the user set and strictly limited
sensing zone. Objects outside the sensing zone (depending on the settings, in
the background, in the foreground or outside of a window that is defined by
two user set distance points) are ignored.

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

Figure 3 Operator controls and displays)

• Minus key 팫

• Plus key 팬

• 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, the
most frequently used parameters can be set directly on the sensor.

4-2-4 Set-up via a PC

All parameters of the sensor can be set with a PC and the OMRON Sensor­SupportSoftware S

established via an optical data interface. The data interface is connected to a
free COM port of a PC/laptop.

User set parameters

4-3-5 Function of connector pin 2

Pin 2 of the connector can be user set as Output 2 (OUT 2), as an alarm out­put, as a teaching input for switching points A and B, as a test input or as a
trigger input.

4-3-6 Switch-on delay

This defines the switch-on response (light-on mode). 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 output does not become active until the
switch-on delay has elapsed.

4-3-7 Switch-off response

This defines the switch-off response (light-on mode). The time is adjustable
between 0 ms and 9999 ms.

• Switch-off delay
The switch-off delay starts as from the time when the measured object
leaves the sensing zone. The output does not become inactive until the
switch-off delay has elapsed.

Section 4-3

• 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 switch-off delay, the output 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 switch-off delay 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.

4-3-10 Keyboard lock

Section 4-3

The measured distance can be displayed on the sensor's display in two differ­ent ways:

• Absolute
The absolute distance between the sensor and the measured object is
displayed with red digits in m.

• Bar
The distance between the sensor and the measured object is displayed
as a green bar chart.

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.
When the keyboard lock is active, changes can only be made if the Minus 팫

and Plus 팬 keys have been pressed simultaneously for 4 seconds. This tem­porarily suppresses keyboard locking. If no key is pressed for about 5 min­utes, the keyboard lock is automatically activated again.

4-3-11 ECO energy saving mode

In the ECO mode, the display switches off automatically approximately 5 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.

4-3-12 Direction of the display

To improve readability, the display can be rotated by 180° when fitted. It is
then "upside down".

4-3-13 Reset

Reset returns the sensor to the factory default settings.

Inputs/Outputs

4-4 Inputs/Outputs

In total, the sensor can be operated with a maximum of three inputs/outputs.
The functions of the inputs/outputs are user determined.

Connector pin 4 is always defined as Output 1 (OUT 1).

Connector pin 2 can be set as Output 2 (OUT 2), as alarm output (ALARM),
as teaching input (TEACH) for switching points A or B, as test input (TEST) or
as trigger input (TRIG).

Connector pin 5 can be set as trigger input (TRIG) as teaching input (TEACH)
for switching points A to D or as test input (TEST)

4-4-1 Inputs

4-4-1-1 Teaching input TEACH

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.

Section 4-4

4-4-1-2 Test input TEST

Connector pins 2 and 5 can be set as test inputs.
The emitter is deactivated if a signal in the operating voltage range is applied

to this input.
If a measured object is located in the sensor's detection zone, regardless of

the user set switching points the receiver detects the absence of the emitted
light reflected by the measured object.

Depending on the object position the output status is altered.

4-4-1-3 Trigger input TRIG

Connector pin 2 and pin 5 can be set as a trigger input.
If a signal in the operating voltage range is applied to this input, the sensor is

prompted to output a measurement result (object distance).

The sensor/switching speed can be increased by the trigger function.

33

Inputs/Outputs

4-4-2 Outputs

4-4-2-1 Switching outputs OUT 1 and OUT 2

When a measured object is detected, the switching outputs OUT 1 (Connec­tor pin 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.

Section 6-1

Assembly, electrical connection and maintenance must only be carried
out by instructed, trained and authorised specialist personnel in
accordance with applicable regulations, after de-energising the power
supply and with the machine switched off.

The machine must be safeguarded against reactivation.

Conversions and changes and tampering in the interior of the sensor,
the data interface and the alignment tool are forbidden.

During assembly, do not knock the sensor or drop it.

The ambient conditions at the assembly location must conform to the
technical data

Contrary to sensors with single triangulation, E3NT with double trian­gulation, allows the measured object's direction of motion to be in all

The sensor must be fitted so that:

• It is correctly aligned before it is adjusted

• It is protected as far as possible against vibration and shock

• It is protected as far as possible against extraneous incident light

• It is protected as far as possible against damage and soiling

• Electrical connection is possible

• It is as accessible as far as possible for maintenance work

• Operation of the push buttons is possible

• The display is visible.

Sensor assembly

If there is a reflecting surface in parallel with the sensor's optical axis,
this might lead to unstable switching 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 at least 10°.

Mirror-like objects can cause malfunction inside and outside the sens­ing range. Avoid mirror-like objects in or close to the optical axis.

(e.g. via a cable conduit).

• 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.

• Conductively connect the cable shield to the connector housing.

• Professionally connect the mating connector to the control cabinet hous-

ing (flat surface, conductive).

• Route supply and signal leads in separate cable ducts.

• Route supply and signal leads as closely as possible to the equipotential

bonding conductor.

• Do not route cable ducts in the proximity of strong electromagnetic inter­ference sources such as electric motors or transformers.

• Suitable protective measures conforming to EN 60204-1 must be taken if
the cable layout does not fully rule out the risk of lightning strikes.

Safety notes

8-1 Safety notes

The diffuse reflective sensors in 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. 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.

Their use is not permitted in applications in which the safety of persons
depends on functioning of the sensor!

8-2 Switching on the operating voltage

After the operating voltage has been switched on, the sensor runs a power-on
reset with a self-test.

The sensor displays the current distance from the measured object if the self­test is successful.

0--0 is displayed if the sensor does not detect a measured object.

Section 8-1

The flashing display ---- appears in the event of a short-circuit at the
outputs.
The sensor continues normal functioning once the short-circuit at the
outputs has been remedied.

48

Aligning the sensor

8-3 Aligning the sensor

Owing to the infrared emitted light, the light spot on the measured
object is not visible.

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

1 Aligning the sensor)

1. Position the measured object at the required position in front of the sensor.

2. Undo the securing screws.

3. Align the sensor's optical axis/alignment marking to the measured object.

4. Tighten the securing screws.

5. Check alignment once again.

Setting the switching points

8-4 Setting the switching points

The switching points can either be user set (Teach-in mode) with a measured
object positioned at the corresponding distance or can be set using the setting
input, for remote setting.

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 suppres­sion modes.

For the 2-point window evaluation mode, two switching points must be set.

8-4-1 Teaching the switching points in the normal mode

The sensor is set at the factory for both outputs to BGS, light on.

1. Place the target object in front of the sensor at the desired position.

2. Teach the switching point for output 1:

• Beginning with the 팬 key, press it simultaneously with the ENTER ●
key. Threshold level is obtained and the output/LED is updated. Status
LED is blinking.

• Using the 팬/팫 keys an adjustment of the switching point is possible.
The output/LED is updated immediately.

• Pressing the ENTER ● key for more than 2 seconds or after 2 minutes
without any activation of the keys, the sensor returns to normal opera­tion. The status LED is turned off.

3. Teach the switching point for Output 2:

• Beginning with the 팫 key, press it simultaneously with the ENTER ●
key.
