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.

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

the sensor.

2 Notes on UL approval

UL: Only for use in applications in accordance with NFPA 79. These devices shall be

protected by a 1 A fuse suitable for 30 V DC.

Adapters listed by UL with connection cables are available.

Enclosure type 1.

3 Intended use

The GRL18(S)V is an opto-electronic photoelectric retro-reflective sensor (referred to as

“sensor” in the following) for the optical, non-contact detection of objects, animals, and

persons. 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.

max. 90 Nm

Note the sensor’s maximum permissible tightening torque of 90 Nm.

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:

– 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.

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 2]. You must ensure that the

optical openings of the sensor and reflector are completely clear.

Figure 2: Alignment

7.2 Check the application conditions

Adjust the distance between the sensor and the reflector according to the correspond‐

ing diagram [ see figure 3] (x = sensing range, y = operating reserve).

Figure 3: Characteristics

After alignment is complete, move a non-transparent object into the path of the

beam. Use and 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

„Troubleshooting table“, page 9.

7.3 Setting

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: 270°). 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.

8.1 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 oper‐

ation, but the operating condi‐

tions are not ideal

Check the operating condi‐

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.
