1 General safety notes

■

Re

ad the operating instructions before commissioning.

■

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

specialis

ts.

■

2006/42/EC

NO

SAFETY

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

■

When commissioning, protect the device from moisture and contamination.

■

The

se operating instructions contain information required during the life cycle of

the sensor.

2 Notes on UL approval

The device must be supplied by a Class 2 source of supply.

UL Env

ironmental Rating: Enclosure type 1

3 Intended use

The GTB2F is an opto-electronic photoelectric proximity sensor (referred to as “sensor”

in the f

ollowing) 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 warranty claim

against SICK AG shall become void.

5 Mounting

Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐

sor

ie

s).

Note the sensor's maximum permissible tightening torque of 0.1 Nm.

Note the preferred direction of the object relative to the sensor, cf. see "Dimensional

drawing", page 11.

6 Electrical installation

The sensors must be connected in a voltage-free state (U

V

= 0 V

). T

he following informa‐

tion must be observed, depending on the connection type:

– Plug connection: note pin assignment: when the lid is open, the male connector

can be swiveled horizontally and vertically.

– Cable: wire color

Only apply voltage/switch on the voltage supply (U

V

> 0 V) once all electrical connec‐

tions have been established.

1 Alignment

Align sensor on ob

ject. Select the position so that the red emitted light beam hits the cen‐

ter of the object. You must ensure that the optical opening (front screen) of the sensor is

completely clear.

LED indicator/fault pattern Cause Measures

Yellow LED does not light up

ev

en though the light beam is

aligned to the object and the

object is within the set sensing

range

No voltage or voltage below

the limit values

Check the power supply,

check all electrical connec‐

tions (cables and plug connec‐

tions)

Voltage interruptions Ensure there is a stable power

supply without interruptions

t to change without notice

9

LED indicator/fault pattern Cause Measures

Sensor is faulty If the power supply is OK,

replace t

he sensor

Yellow LED lights up, no object

in the path of the beam

The sensing range distance is

too large

Reduce the sensing range,

see Figures 6-8 and table 3

Object is in the path of the

beam, yellow LED does not

light up

Distance between the sensor

and the object is too long or

sensing range is set too short

Increase the sensing range,

see Figures 6-8 and table 3

9 Disassembly and disposal

The sensor must be disposed of according to the applicable country-specific regula‐

tions

. Efforts should be made during the disposal process to recycle the constituent

materials (particularly precious metals).

NOTE

Dispos

al of batteries, electric and electronic devices

•

According to international directives, batteries, accumulators and electrical or

electronic devices must not be disposed of in general waste.

•

respective public collection points.

•

WEEE:

This symbol on the product, its package or in this document, indi‐

ca

tes that a product is subject to these regulations.

10 Maintenance

SICK sensors are maintenance-free.

We r

ecommend doing the following regularly:
