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.

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:

– Male connector connection: pin assignment

– Cable: core color

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

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

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).
