1 General safety notes

■

Read these operating instructions before commissioning the device.

■

Connection, mounting and configuration of the device must only be carried

out by qualified personnel.

■

2006/42/EC

NO

SAFETY

This device does not constitute a safety component as defined in the

Machinery Directive.

■

When commissioning the device, ensure adequate protection against mois‐

ture, contamination and UV radiation (sunlight).

■

These operating instructions contain information required during the life cycle of

the photoelectric sensor.

2 Notes on UL approval

The device shall be supplied from an isolating transformer having a secondary overcur‐

rent protective device that complies with UL 248 to be installed in the field rated either:

a) max 5 amps for voltages 0 ~ 20 V (0 ~ 28.3 V peak), or

b) 100 / Vp for voltages of 20 ~ 30 V (28.3 ~ 42.4 V peak).

Alternatively, they can be supplied from a Class 2 power supply.

UL Environmental Rating: Enclosure type 1

3 Intended use

The WTF4FD is an opto-electronic photoelectric proximity sensor (referred to as “sen‐

sor” 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.

5 Mounting

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

sories).

Figure 1: Alignment of the sensor relative to the object direction

Note the sensor’s maximum permissible tightening torque of < 0,4 Nm.

Note the preferred direction of the object relative to the sensor, cf. see figure 1, page 6.

6 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: Pin assignment

– Cable: Wire color

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

been established.

WTF4FD: visible red light. Align the sensor with the 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

Figure 2: Alignment

7.2 Check the application conditions:

Sensing range

WTF4FD are photoelectric proximity sensors with foreground suppression. The photo‐

electric proximity sensor requires a background as a reference. The radiance factor

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

distance (x) between the photoelectric proximity sensor and background as well as the

minimum object height (y) must be upheld. As a rule, a WTF4FD 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 radiance capability of background and object with the

associated diagram (see figure 3, page 8) (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 = 45 mm, y = 0,8 mm, i.e. a black object is detected from a height of at

least 0,8 mm on a white background.

Sensing range adjustment

WTF4FD-xxxxxx1xAxx

Adjustment via a potentiometer:

Clockwise rotation: Sensing range increased.

Counterclockwise rotation: Sensing range reduced.

WTF4FD-xxxxxx2xAxx

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

yellow 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.

WTF4FD-xxxxxx3x

Adjustment via teach-in: The sensing range is adjusted by pressing the teach-in button

(approx. 1-3 sec.).
