Safety notes
R
ead t
he operating instructions before commissioning.
Connection, mounting, and setting may only be performed by trained specialists.
Not a safety component in accordance with the EU Machinery Directive.
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 connec‐
tion cables are available. 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 Correct use
The GRTB18(S) is an opto-electronic photoelectric proximity sensor (referred to as "sen‐
sor" in the f
ollowing) for the optical, non-contact detection of objects, animals, and per‐
sons. If the product is used for any other purpose or modified in any way, any warranty
claim against SICK AG shall become void.
Photoelectric proximity sensor with background suppression.

3 Commissioning
1 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 diagram [H] (x = sensing range, y = transition range between the set
sensing range and suppression of the background as a % of the sensing range
(object remission / background remission). Remission: 6% = black , 18% = grey
, 90% = white (referring to standard white as per DIN 5033).
The minimum distance (= y) for background suppression can be determined from
diagram [H] as follows:
Example: x = 40 mm, y = 10% => 10% % of 40 mm = 4 mm. That is, the back‐
ground is suppressed at a distance of > 44mm from the sensor.

2 Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sor
ies).
The maximum permissible tightening torque is listed in Table K.
Note the preferred direction of the object relative to the sensor.
3 The sensors must be connected in a voltage-free state (V
S
= 0 V). The inf
ormation
in the graphics [B] must be observed, depending on the type of connection:

4 Align the sensor with the object. Select the position so that the red emitted light
beam hits t
he center of the object. You must ensure that the optical opening (front
screen) of the sensor is completely clear [E]. We recommend making the adjust‐
ments using an object with a low remission.

Sensor with potentiometer:
The sensing rang
e is adjusted with the potentiometer (type: 270°). Clockwise rota‐
tion: sensing range increased; counterclockwise rotation: sensing range reduced.
We recommend placing the switching state in the object, e. g., see graphic F. 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 graphic C).
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.

Measures /
Measures
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 graphic F.
Yellow LED lights up, no object
in the path of the beam
Distance between the sen‐
sor and the background is too
short
Reduce the sensing range,
see graphic F
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,
see graphic F
7 Disassembly and disposal
The sensor must be disposed of according to the applicable country-specific regula‐
tions. Ef
forts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).
