3 Product description

3.1 Intended use

The WSE4F is an opto-electronic through-beam photoelectric sensor (referred to as

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

persons. A sender (WS) and a receiver (WE) are required for operation. 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 sensors (sender and receiver) using suitable mounting brackets (see the SICK

range of accessories). Align the sender and receiver with each other.

NOTE

When mounting multiple through-beam photoelectric sensors next each other, swap

the arrangement of the sender (WSO4F) and receiver (WEO4F) for every second pair.

Also maintain a sufficiently large distance between the pairs based on the light spot

diameter of the sender (WSO4F). See figure 1 and figure 2.

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

6 Additional functions

Alarm: Operation with borderline light reception

Alarm output: The sensor (WSE4F) features a pre-failure notification output (“Alarm”

in the connection diagram), which issues a notification if the sensor is only ready for

operation to a limited extent. The LED flashes in this case. Possible causes: Sensor

is contaminated, sensor is out of alignment. In the good state: LOW (0), if excessively

contaminated HIGH (1).

Health

Health output: The sensor (WSE4F) features a pre-failure notification output (“Health”

in the connection diagram), which issues a notification if the sensor is only ready for

operation to a limited extent or the cable has been interrupted. Possible causes: Sensor

LED indicator flashes in this case.

Test input

Test input: The WSE4F sensors feature a test input (“Test” on the connection diagram

[see table 2, page 7]), which can be used to switch the sender off and, therefore, check

that the sensor is functioning correctly: If female cable connectors with LED indicators

are used, you must ensure that the TI is assigned accordingly.

It is important that there is no object between the sender and receiver, activate the test

input (see the connection diagram [see table 2, page 7]).

The send LED is shut down or the detection of an object is simulated. Refer to table 8

to check the function. If the switching output fails to behave in accordance with the

following table, check the application conditions, see "Troubleshooting", page 12.

7.1 Alignment

WSO4FP: Align the sender (WSO4F) with the receiver (WEO4F). Select the position so

that the red emitted light beam hits the receiver. Tip: Use white paper or a reflector as

an alignment aid. The sender must have a clear view of the receiver, with no object in

the path of the beam [see figure 3]. You must ensure that the optical openings (front

screen) of the sensors are completely clear.

WSO4FI: Align the sender (WSO4F) with the receiver (WEO4F). Select the position so

that the infrared light (not visible) hits the receiver. The correct alignment can only be

detected via the LEDs. See figure 3 and table 6. The sender must have a clear view of

the receiver, with no object in the path of the beam. You must ensure that the optical

openings (front screen) of the sensors are completely clear.

7.2

Check the application conditions:

Sensing range

WSE4F are through-beam photoelectric sensors that can be used at shorter distances,

in particular due to the large sensing range or the very high operating reserve.

Observe the application conditions: Adjust the distance between the sender and the

receiver according to the corresponding diagram [see figure 6 and see figure 5,

page 11] (x = sensing range, y = operating reserve).

If several through-beam photoelectric sensors which are installed next to one another

are to be used, we recommend swapping the sender/receiver arrangement at every

second through-beam photoelectric sensor and ensuring that there is sufficient dis‐

tance between the through-beam photoelectric sensors. By doing this, mutual interfer‐

ence can be prevented [see figure 1].

Check the function as described in table 6. If the switching output fails to behave as

described in table 6, check the application conditions.

7.3 Setting

Sensitivity adjustment

WEO4Fx-xxxxxx30A00:

NOTE

For some applications (e.g., when switching errors arise due to reflections), we recom‐

mend slightly misaligning the sender and receiver or significantly reducing the oper‐

ating reserve. The WSE4F can suppress switching errors under these conditions by

means of a teach-in (via IO-Link or using the Teach-in pushbutton on the housing). This

reduces the operating reserve at the same time.
