1 General safety notes

■Read the operating instructions before commissioning.

■

Connection, mounting, and configuration may only be performed by trained

specialists.

■

2006/42/EC

SAFETY

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

■

Do not install the sensor at locations that are exposed to direct UV radiation

(sunlight) or other weather influences, unless this is expressly permitted in the

operating instructions.

■When commissioning, protect the device from moisture and contamination.

■These operating instructions contain information required during the life cycle of

the 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 WLD4F is an opto-electronic photoelectric retro-reflective sensor (referred to as

“sensor” in the following) for the optical, non-contact detection of objects, animals, and

persons. A reflector is required for it to function. 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 and the reflector using suitable mounting brackets (see the SICK

range of accessories). Align the sensor and reflector with each other.

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

6 Electrical installation

Operation in standard I/O mode:

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.

Operation in IO-Link mode: Connect the device to a suitable IO-Link master and inte‐

grate in the master or control via IODD/function block. The green LED flashes on the

sensor. IODD and function block are available to download from www.sick.com under

the part number.

7 Commissioning

7.1 Alignment

Align the sensor with a suitable reflector. Select the position so that the red emitted

light beam hits the center of the reflector. The sensor must have a clear view of the

reflector, with no object in the path of the beam [see figure 1]. You must ensure that the

optical openings of the sensor and reflector are completely clear.

7.2 Check the application conditions:

Sensing range

Adjust the distance between the sensor and the reflector according to the correspond‐

ing diagram [figure 3] (x = sensing range, y = operating reserve).

After alignment, place a non-transparent object into the path of the beam. Check the

function as described in figure X. If the switching output fails to behave as described in

figure X, check the application conditions.
