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 GTB6V 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 Mounting

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

sories).

< 0.4 Nm

Note the preferred direction of the object relative to the sensor, cf. figure 1.

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].

Figure: Alignment

2Sensing range

COMMISSIONING 6

8021849 | SICK

Subject to change without notice 7

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 figure X] (x = sensing range, y = monitored area between the set sensing range

and background suppression as a % of the sensing range (object remission/background

remission)). Remission: 6% = black 1, 18% = gray 2, 90% = white 3 (referring to stan‐

dard white as per DIN 5033).

The minimum distance (= y) for background suppression can be determined from diagram

[ see figure X 1] as follows:

Example: x = 150 mm, y = 20 => 20% of 150 mm = 30 mm. That is, the background is

suppressed at a distance of > 180 mm from the sensor.

For other sensing ranges, please refer to individual datasheets.

3Sensing range setting

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

sensing range increased; counterclockwise rotation: sensing range reduced. We recom‐

mend placing the object within the sensing range, e.g. see table 3. Once the sensing range

has been adjusted, the object is removed from the path of the beam, which causes the

background to be suppressed and the switching output to change [see table 2].

Table 3: 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 4: 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) / Check

sensing range and adjust if

necessary, see figure 3,

page 8

Yellow LED lights up, no object

in the path of the beam

Distance between the sensor

and the background is too

short

Reduce the sensing range,

see figure 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,

take note of the distance

between the sensor and the

background, see figure 3
