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.

■

Do not install the sensor at locations that are exposed to direct sunlight

or other weather influences, unless this is expressly permitted in the operating

instructions.

■When commissioning, protect the device from moisture and contamination.

■These operating instructions contain information required during the life cycle of

the sensor.

EN/IEC 60825-1:2014

IEC60825-1:2007

LASER CLASS 1

Laser

Maximum pulse power < 5.95 mW

Puls length: 2 µs

Wavelength: 670 - 690 nm

Complies with FDA performance

standards except for conformance with

IEC 60825-1 Ed. 3,

as described in Laser Notice No. 56,

dated May 8, 2019

ATTENTION

WARNING: Interruption, manipulation or incorrect use can lead to hazardous exposure

due to laser radiation.

2 Notes on UL approval

The device shall be supplied from an isolating transformer having a secondary overcur‐

rent protective device that complies with UL 248 to be installed in the field rated either:

a) max 5 amps for voltages 0 ~ 20 V (0 ~ 28.3 V peak), or

b) 100 / Vp for voltages of 20 ~ 30 V (28.3 ~ 42.4 V peak).

Alternatively, they can be supplied from a Class 2 power supply.

UL Environmental Rating: Enclosure type 1

3 Intended use

The GL6L is an opto-electronic photoelectric retro-reflective sensor (referred to as “sen‐

sor” in the following) for the optical, non-contact detection of objects. A reflector is

required for this product to function. 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 and the reflector using suitable mounting brackets (see the SICK

range of accessories). Align the sensor and reflector with each other.

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: pin assignment

– Cable: wire color

Only apply voltage/switch on the voltage supply (UV > 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

7 Commissioning

7.1 Alignment

Align the sensor with a suitable reflector. Select the position so that the red emitted

light beam hits the center of the reflector. The sensor must have a clear view of the

reflector, with no object in the path of the beam [see figure 1]. You must ensure that the

optical openings of the sensor and reflector are completely clear.

Figure 1: Alignment

7.2 Sensing range

Adjust the distance between the photoelectric sensor and the reflector according to the

relevant diagram [see figure 2] (x = sensing range, y = operating reserve).

After alignment, place a non-transparent object into the path of the beam. Check the

function as described in table 2. If the switching output fails to behave as described in

table 2, check the application conditions.

7.3 Settings

Sensitivity setting

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

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

operating reserve increased; counterclockwise rotation: operating reserve reduced. We

recommend setting the potentiometer to “Maximum”. A lower operating reserve may be

necessary for depolarizing surfaces.

The sensor is adjusted and ready for operation.

8 Troubleshooting

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

Table 3: Troubleshooting

LED indicator/fault pattern Cause Measures

Yellow LED does not light up

even though the light beam

is aligned to the reflector and

there is no object in the path of

the beam

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

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,

indicates 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.
