Operating instructions
1 Safety notes
■Read the operating instructions before commissioning.
■Connection, mounting, and setting may only be performed by trained specialists.
■Not a safety component in accordance with the EU Machinery Directive.
■UL: Only for use in applications in accordance with NFPA 79. These devices shall
be protected by a 1 A fuse suitable for 30 V DC. Adapters listed by UL with connec‐
tion cables are available. 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 Correct use
The GTE6-Line 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 per‐
sons. If the product is used for any other purpose or modified in any way, any warranty
claim against SICK AG shall become void.

3 Commissioning
1 Check the application conditions: Adjust the sensing range and the remission capa‐
bility of the object according to the corresponding diagram [H] (x = sensing range, y
= operating reserve).
During this process, an object can only be detected in front of a background if the
remission capability of the object is significantly higher than that of the background
or if the distance between the object and the background is sufficiently long.

in the graphics [B] must be observed, depending on the type of connection:

Sensor with potentiometer:
The sensitivity (sensing range) is adjusted with the potentiometer (type: 5-turn).
Clockwise rotation: sensitivity (sensing range) increased; counterclockwise rotation:
sensitivity (sensing range) reduced. We recommend placing the switching state in
the object, e. g., see graphic F. Once the sensitivity has been adjusted, the object is
removed from the path of the beam. The switching output changes (see graphic C).
The sensor is adjusted and ready for operation. Refer to graphics C and G to check
the function. If the switching output fails to behave in accordance with graphic C,
check application conditions. See section Fault diagnosis.

Sensor mit Potentiometer:
Mit dem Potentiometer (Art: 5-Gang) wird die Empfindlichkeit (Schaltabstand) ein‐
gestellt. Drehung nach rechts: Erhöhung der Empfindlichkeit (Schaltabstand), Dre‐
hung nach links: Verringerung der Empfindlichkeit (Schaltabstand). Wir empfehlen,
den Schaltabstand in das Objekt zu legen, z. B. siehe Grafik F. Nachdem die Emp‐
findlichkeit eingestellt worden ist, das Objekt aus dem Strahlengang entfernen. Der
Schaltausgang ändert sich (siehe Grafik C).
Sensor ist eingestellt und betriebsbereit. Zur Überprüfung der Funktion Grafik C

1 Vérifier les conditions d'utilisation : comparer la portée et les caractéristiques de
réflectivité de l'objet à l'aide du diagramme [E] correspondant. (x = portée, y =
réserve de fonctionnement).
Ce faisant, il n'est possible de détecter un objet devant un arrière-plan que si les
caractéristiques de réflectivité de l'objet sont largement supérieures à celles de
l'arrière-plan en question ou si la distance entre l'objet et l'arrière-plan est suffi‐
sante.

26 Especificações de uso
O GTE6-Line é um sensor fotoelétrico de proximidade utilizado para a detecção óptica,
sem contato, de objetos, animais e pessoas. Qualquer utilização diferente ou alter‐
ações do produto provocam a perda da garantia da SICK AG.
Interruptor fotoelétrico de reflexão energético.

27 Colocação em operação
1 Verificar as condições de uso: equiparar a distância de comutação e a refletividade
do objeto com o respectivo diagrama [cp. H]. (x = distância de comutação, y =
reserva de função).
Um objeto só pode ser detectado à frente de um fundo, se a refletividade do objeto
for significativamente maior do que a refletividade do fundo ou se a distância entre
o objeto e o fundo for suficientemente grande.

2 Montar o sensor numa cantoneira de fixação adequada (ver linha de acessórios da
SICK).
Observar o torque de aperto máximo permitido de 0.4 Nm para o sensor.
3 A conexão dos sensores deve ser realizada em estado desenergizado (UV = 0 V).
Conforme o tipo de conexão, devem ser observadas as informações contidas nos
gráficos [cp. B]:

Instalar ou ligar a alimentação de tensão (UV > 0 V) somente após a conclusão de
todas as conexões elétricas. O indicador LED verde está aceso no sensor.

L = comutação por luz
D = comutação por sombra
4 Alinhar o sensor ao objeto. Posicionar, de forma que o feixe da luz de emissão ver‐
melha incida sobre o centro do objeto. Certificar-se de que a abertura óptica (vidro
frontal) do sensor esteja completamente livre [cp. E].

Sensor com potenciômetro:
A sensibilidade (distância de comutação) é ajustada com o potenciômetro (tipo: 5
voltas). Giro para direita: aumento da sensibilidade (distância de comutação); giro
para esquerda: redução da sensibilidade (distância de comutação). Recomenda‐
mos posicionar a distância de comutação no objeto, por ex., como no gráfico F.
Após o ajuste da sensibilidade, remover o objeto do caminho óptico. A saída de
comutação se modifica (ver gráfico C).
O sensor está ajustado e operacional. Utilizar os gráficos C e G para verificar o fun‐
cionamento. Se a saída de comutação não se comportar de acordo com o gráfico
C, verificar as condições de uso. Ver seção Diagnóstico de erros.
