1 Safety notes

■Read the operating instructions before commissioning.

■

Connection, mounting, and setting may only be performed by skilled per‐

son.

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

■Power supply: Class 2

Enclosure type 1

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

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

the sensor.

2 Intended use

The GRTE18(S)V 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 war‐

ranty claim against SICK AG shall become void.

The GRTE18(S)V sensor complies with the Radio Safety Requirements (EMC) for the

industrial sector (Radio Safety Class A). It may cause radio interference if used in a resi‐

dential area.

max. 90 Nm

Note the sensor’s maximum permissible tightening torque of 90 Nm.

5 Electrical installation

The sensors must be connected in a voltage-free state (UV = 0 V). The following informa‐

tion must be observed, depending on the connection type:

– Male connector connection: pin assignment

– Cable: wire color

Only apply voltage/switch on the voltage supply (UV > 0 V) once all electrical connec‐

tions have been established. The green LED indicator lights up on the sensor.

6 Commissioning

1Alignment

Align the sensor with the object. Select the position so that the red emitted light beam hits

the center of the object. You must ensure that the optical opening (front screen) of the sen‐

sor is completely clear [see figure].

Align the sensor with the object. Select the position so that the infrared light (not visible)

hits the center of the object. The correct alignment can only be detected via the LED indi‐

cators. See figure and table 3. You must ensure that the optical opening (front screen) of

the sensor is completely clear.

2Sensing range

Check the application conditions: Adjust the sensing range and the remission capability of

the object according to the corresponding diagram [see figure 10]. (x = sensing range, y =

operating reserve).

During this process, an object can only be detected in front of a background if the remis‐

sion capability of the object is significantly higher than that of the background or if the dis‐

tance between the object and the background is sufficiently long.

Use and Table 3 to check the function. If the switching output fails to behave in accordance

with Table 3, check the application conditions. See section Fault diagnosis.

3Sensing range setting

Sensor which it is not possible to set: The sensor is adjusted and ready for operation.

The sensitivity (sensing range) is adjusted with the potentiometer (type: 270°). Clockwise

rotation: sensitivity (sensing range) increased; counterclockwise rotation: sensitivity (sens‐

ing range) reduced. We recommend placing the object within the sensing range. Once the

sensitivity is set, remove the object from the beam path. The switching output changes.

Table 4: Sensing range setting

The sensor is adjusted and ready for operation.

7 Troubleshooting

The Troubleshooting table indicates which measures are to be taken if the sensor stops

working.

7.1 Troubleshooting table

Table 5: Troubleshooting

LED indicator/fault pattern Cause Measures

Green LED does not light up No voltage or voltage below

the limit values

Check the power supply,

check all electrical connec‐

tions (cables and plug connec‐

tions)

Green LED does not light up Voltage interruptions Ensure there is a stable power

supply without interruptions

Green LED does not light up Sensor is faulty If the power supply is OK,

replace the sensor

Yellow LED flashes Sensor is still ready for opera‐

tion, but the operating condi‐

tions are not ideal

Check the operating condi‐

tions: Fully align the beam of

light (light spot) with the

object / Clean the optical sur‐

faces / Readjust the sensitiv‐

ity (potentiometer)
