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 Correct use

The GRSE18 is an opto-electronic through-beam photoelectric sensor (referred to as

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

persons. A sender (GRS) and a receiver (GRE) are required for operation. If the product

is used for any other purpose or modified in any way, any warranty claim against SICK

AG shall become void.

4 Commissioning

4.1 Check the application conditions

Observe the application conditions: Adjust the distance between the sender and the

receiver according to the corresponding diagram (x = sensing range, y = operating

reserve).

If several through-beam photoelectric sensors which are installed next to one another

are to be used, we recommend swapping the sender/receiver arrangement at every

second through-beam photoelectric sensor and ensuring that there is sufficient dis‐

tance between the through-beam photoelectric sensors. By doing this, mutual interfer‐

ence can be prevented.

4.2 Mounting

Mount sensors (sender and receiver) using suitable mounting brackets (see the SICK

range of accessories). Align the sender and receiver with each other [K].

Observe the maximum permissible tightening torque of the sensor of 2.0 Nm for

metal/0.9 Nm for plastic [K].

4.3 Electronics

The sensors must be connected in a voltage-free state (VS = 0 V). The information in the

graphics [B] must be observed, depending on the type of connection:

Test = test input (see Additional functions)

4.4 Alignment

Align the sender (GRS18) with the receiver (GRE18). Select the position so that the red

emitted light beam hits the receiver. Tip: Use white paper or a reflector as an alignment

aid. The sender must have a clear view of the receiver, with no object in the path of

the beam [see figure 4]. You must ensure that the optical openings (front screen) of the

sensors are completely clear.

Figure 4: Alignment

4.5 Adjustment

Sensor with potentiometer:

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."

The sensor is adjusted and ready for operation. Refer to graphics C and G to check the

function. If the switching output fails to behave in accordance with graphic C, check

application conditions. See section Fault diagnosis.

5 Additional functions

Test input: The GRSE18 sensor features a test input ("TI" or "Test" on the connection

diagram [B]), which can be used to switch the sender off and therefore check that the

sensor is functioning correctly: If female cable connectors with LED indicators are used,

you must ensure that the TI is assigned accordingly.

There must be no object between the sender and receiver; activate the test input (see

the connection diagram [B], TI at 0 V). The send LED is shut down or the detection of

an object is simulated. Refer to graphics C and G to check the function. If the switching

output fails to behave in accordance with graphic C, check application conditions. See

section Fault diagnosis.

6 Troubleshooting

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

Table Fault diagnosis

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

Green LED lights up, no output

signal when object is detected

Test input (Test) is not con‐

nected properly

See the note on connecting

the TI

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

receiver. / Clean the optical

surfaces . / Readjust the sen‐

sitivity (potentiometer) / If the

potentiometer is set to the

max. sensing range: Reduce

the distance between the

sender and the receiver and

check / Check sensing range

„Check the application condi‐

tions“, page 5.

Yellow LED lights up, no object

in the path of the beam

The beam of light of a pho‐

toelectric through-beam sen‐

sor hits the receiver of

another (neighboring) photo‐

electric through-beam sensor

Swap the sender and receiver

arrangement at every sec‐

ond through-beam photoelec‐

tric sensor and ensure that

there is sufficient distance

between the through-beam

photoelectric sensors, see

figure X.

7 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.

8 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.
