specialists.

■

2006/42/EC

NO

SAFETY

Not a safety component in accordance with the EU Machinery Directive.

■

UL Environmental Rating: Enclosure type 1

2 Intended use

The WTF16 is an opto-electronic photoelectric proximity sensor (referred to as “sensor”

in the following) for the optical, non-contact detection of objects, animals, and persons.

If the product is used for any other purpose or modified in any way, any warranty claim

against SICK AG shall become void.

4 Mounting

Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐

sories).

Note the sensor’s maximum permissible tightening torque of < 1,3 Nm.

Note the preferred direction of the object relative to the sensor, see figure 1, .

5 Electrical installation

The sensors must be connected in a voltage-free state. The following information must

be observed, depending on the connection type:

– Male connector connection: Note pin assignment.

– Cable: Wire color

Only apply voltage/switch on the voltage supply once all electrical connections have

been established.

6 Additional functions

Test input

Test input: The WTF16 sensors feature a test input (“TI” or “Test” on the connection dia‐

gram [see table 2, table 3]), which can be used to switch the sender off and, therefore,

check that the sensor is functioning correctly: If female cable connectors with LEDs are

used, you have to ensure that the TI is assigned accordingly.

It is important that there is no object between the sensor and background; activate the

test input (see the connection diagram [see table 2, table 3]). The send LED is shut

down or the detection of an object is simulated. Refer to table 5 to check the function.

If the switching output fails to behave in accordance with table 5, check the application

conditions. See section Fault diagnosis.

7 Commissioning

7.1 Alignment

WTF16P: Align sensor on background. Select the position so that the red emitted light

beam hits the objects. You must ensure that the optical opening (front screen) of the

sensor is completely clear [see figure 1].

WTF16I: Align the sensor with the background. Select the position so that the infrared

light (not visible) hits the objects. The correct alignment can only be detected via the

LEDs. see figure 1 and table 4. You must ensure that the optical opening (front screen)

of the sensor is completely clear.

Figure 1: Alignment

7.2 Check the application conditions:

Sensing range

WTF16 are photoelectric proximity sensors with foreground suppression. The photoelec‐

tric proximity sensor requires a background as a reference. The radiance factor and

position of the background should remain as uniform as possible. The maximum dis‐

tance (x) between photoelectric proximity sensor and background as well as the mini‐

mum object height (y) must be upheld.

As a rule, a WTF16 is used to detect very flat objects on a conveyor belt.

Check the application conditions: Compare distance between sensor and background,

minimal object height as well as remission capability of background and object with the

associated diagram (see figure 2, page 9, see figure 4, page 10 or see figure 4,

page 10) (x = sensing range, y = minimum object height. Radiance factor: 6% = black

1, 90% = white 2 (referring to standard white as per DIN 5033).

Example: x = 300 mm, y = 7 mm, i.e. a white object is detected from a height of at least

7 mm on a black background. The distance between photoelectric proximity sensor and

background is 300 mm.

7.3 Sensing range adjustment

WTF16x-xxxxxx2xAxx with Teach-Turn adjustment:

The sensing range is adjusted by pressing the teach-in button (approx. 1-3 sec.).

Depending on the requirements, the potentiometer can be used for fine-tuning (without

pressing the teach-in button).

Clockwise rotation: Sensing range increased.

Counterclockwise rotation: Sensing range reduced.

The sensing range can also be adjusted using just the potentiometer.

1.

1...3 sec.

2. The conveyor belt should now be put into operation without any objects. If the yel‐

low LED indicator lights up permanently during the test run, the sensing range is

set correctly.

3. If the yellow LED indicator does not light up briefly during the test run, reduce the

sensing range minimally. This increases the minimum object height accordingly.

Then check the detection with the object.

WTF16x-xxxxxx1xAxx with potentiometer:

The sensing range is adjusted with the potentiometer.

Clockwise rotation: Sensing range increased.

Counterclockwise rotation: Sensing range reduced.
