UL Environmental Rating: Enclosure type 1

3 Intended use

The GTB6L is an opto-electronic photoelectric proximity sensor (referred to as “sensor”

in the following) for the optical, non-contact detection of objects. If the product is used

for any other purpose or modified in any way, any warranty claim against SICK AG shall

become void.

6 Electrical installation

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

V

= 0 V). The following informa‐

tion must be observed depending on the connection type:

– Plug connection: pin assignment

– Cable: wire color

Only apply voltage/switch on the voltage supply (U

V

> 0 V) once all electrical connec‐

tions have been established.

Explanation of connection terminology:

BN = Brown

WH = White

BU = Blue

BK = Black

n. c. = no connection

Q = switching output 1

Q = switching output 2

L+ = supply voltage (Uv)

M = common

7 Commissioning

7.1 Alignment

Align sensor on 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

sensor is completely clear [see figure 2].

Figure 2: Alignment

7.2 Sensing range

Adjust the mounting position so that the sensing range and background are within

specification. Refer to see figure 3, page 9.

NOTE

Please note the minimum range of 5 mm.

7.3 Settings

Sensing range setting

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

The sensing range is adjusted with the potentiometer (type: 5-turn). Clockwise rotation:

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

mend placing the object within the sensing range, e.g. see figure 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].

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

Sensor is faulty If the power supply is OK,

replace the sensor

Yellow LED flashes Sensor is still ready for oper‐

ation, 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 / Check sensing range

and adjust if necessary

Yellow LED lights up, no object

in the path of the beam

The sensing range distance is

too large

Reduce the sensing range

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

Reduce the sensing range

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).
