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.

■

When commissioning, protect the device from moisture, contamination and

UV radiation (sun light).

■These 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 Environmental Rating: Enclosure type 1

3 Intended use

The GTB2F 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 warranty claim

against SICK AG shall become void.

4 Operating and status indicators

1LED indicator green: supply voltage active

2LED indicator yellow: status of received light beam

5 Mounting

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

sories).

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 (UV = 0 V). The 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 (UV > 0 V) once all electrical connec‐

tions have been established.

Explanation of the connection diagram (Tables pin assignment):

Q = switching outputs

n. c. = not connected

DC: 10 ... 30 V DC

7 Commissioning

1Alignment

Align sensor on object. 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.

2Sensing range

Check the application conditions: Adjust the sensing range and distance to the object or

background and the remission capability of the object according to the corresponding dia‐

gram [see table 3].

Use see table 2, page 7 to check the function. If the switching output fails to behave in

accordance with the table, check the application conditions. See section Fault diagnosis.

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

8 Troubleshooting

The Troubleshooting table indicates measures to be taken if the sensor stops working.

Table 4: Troubleshooting

LED indicator/fault pattern Cause Measures

Yellow LED does not light up

even 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

TROUBLESHOOTING 8

8023328.18HX | SICK

Subject to change without notice 9

LED indicator/fault pattern Cause Measures

Sensor is faulty If the power supply is OK,

replace the 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

Disposal 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.

•The owner is obliged by law to return this devices at the end of their life to the

respective public collection points.

•

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

cates that a product is subject to these regulations.

10 Maintenance

SICK sensors are maintenance-free.

We recommend doing the following regularly:

•Clean the external lens surfaces

•Check the screw connections and plug-in connections

No modifications may be made to devices.
