1 Safety information

1.1 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 sunlight

or other weather influences, unless this is expressly permitted in the operating

instructions.

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

the sensor.

1.2 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

2 Intended use

The WSE26 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 (WS26) and receiver (WE26) for every second pair.

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

diameter of the sender (WS26), see figure 1.

Figure 1: Arrangement of multiple through-beam photoelectric sensors

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

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 supply/switch on the voltage once all electrical connections have been estab‐

lished.

6 Additional functions

Alarm

Alarm output: The sensor (WSE26) features a pre-failure notification output (“Alarm”

in the connection diagram [see table 3]), 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 (WSE26) features a pre-failure notification output (“Health”

in the connection diagram [see table 3]), 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 is contaminated, sensor is out of alignment, cable is damaged. In the

good state: HIGH (1), if excessively contaminated or in the event of cable interruption

LOW (0). The yellow LED indicator flashes in this case.

Test input

Test input: The sensors (WSO26P, WSO26I) feature a test input (“TI” or “Test” on the

connection diagram [see table 2]), 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 have to 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]).

The send LED is shut down or the detection of an object is simulated. Refer to table 7

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

graphic, check the application conditions, see "Troubleshooting", page 12.

7 Commissioning

7.1 Alignment

WSO26P: Align the sender with the receiver. 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 table]. You must ensure that the optical openings (front screen) of the sensors are

completely clear.
