3 Intended use

The ZTB18 is an opto-electronic photoelectric background suppression proximity sensor

(referred to as “sensor” in the following) for the optical, non-contact detection of

objects, animals, and persons. If the product is used for any other purpose or modified

in any way, any warranty claim against SICK AG shall become void.

Note the preferred orientation of the sensor relative to the direction of object motion,

refer to figure 2.

6 Electrical installation

The sensors must be connected in a voltage-free state (U

V

= 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 (U

V

> 0 V) once all electrical connec‐

tions have been established.

Explanation of connection terminology used in Tables 1-3:

BN = Brown

WH = White

BU = Blue

BK = Black

n. c. = no connection

Q1 = switching output 1

Q2 = switching output 2

L+ = supply voltage (Uv)

M = common

L.ON = light operate

D.ON = dark operate

NOTE

The sensor outputs may come equipped with a factory set ON delay and/or OFF delay.

This is indicated by a Txx suffix at the end of the Model Number (Zxx18-xxxxxxTxx).

7 Commissioning

1 Alignment

ZTB18-xxxxx2: align sensor on the target object. Select the position so that the red emitted

light beam hits the center of the target object. Ensure that the optical opening (front

screen) of the sensor is completely clear [see figure 3].

ZTB18-xxxxx1: align sensor on target object. Select the position so that the infrared light

(not visible) hits the center of the target object. The correct alignment can only be detected

via the LED indicators on the sensor. See figure 3 and table 1. Ensure that the optical

opening (front screen) of the sensor is completely clear.

Figure 3: Alignment

2 Sensing range

Check the application conditions: The ZTB18 is available in two fixed sensing range (on

white, 90%) versions:

•

50mm (ZTB18-xxxxxxD02)

•

100mm (ZTB18-xxxxxxD04)

Adjust the mounting position so that the sensing range and background are within specifi‐

cation. Refer to see figure 4, page 11.

NOTE

Please note the minimum range of 5 mm.

yx

White back-

ground (90%)

Figure 4: Sensing range on black

Sensing range on black, 6%:

•

ZTB18-xxxxxxD02: x = 47 mm, y = 4 mm

•

ZTB18-xxxxxxD04: x = 93 mm, y = 8 mm

Use see table 1, page 7 to check the function. If the switching output fails to behave in

accordance with see table 1, page 7, check the application conditions.

3 Sensing range setting

Sensor not able to be set: The sensor has been adjusted to maximum sensing range by the

factory and is ready for operation.

4 Operation with marginal light reception

The sensor will provide a pre-failure notification by flashing the orange LED indicator when

operating with marginal light reception. This may be the result of incorrect alignment, cont‐

aminated optical surface(s), and/or insufficient light remission from the target. The sensor

may be equipped with a Health or Alarm output, which provide a discrete signal when the

sensor is operating in the marginal condition. Refer to table 2 for additional detail on

Health/Alarm output operation.

8 Troubleshooting

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

Table 4: Troubleshooting

LED indicator/fault pattern Cause Measures

Yellow LED does not light up

even though the sender is

aligned to the object and the

object is within the set sensing

range

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; if Alarm /

Health is present then take

note of the corresponding out‐

put signal

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

Yellow LED lights up, no object

in the path of the beam

Stray background remission Check the background for

highly reflective objects and

try to block from the sensors

field of view

Object is in the path of the

beam, yellow LED does not

light up

Object remission is too low Reduce distance between

sensor and object. Note that

the object may not have

enough remission for detec‐

tion.

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.

•

This symbol on the product, its package or in this document, indicates

that a product is subject to these regulations.

10 Maintenance

SICK recommends the following regular maintenance:

•

Clean the external optical surfaces

•

Check the screw connections and plug-in connections

No modifications may be made to devices.

17 Elektrische Installation

Anschluss der Sensoren muss spannungsfrei (U

V

= 0 V) erfolgen. Je nach Anschlussart

sind die folgenden Informationen zu beachten:

– Steckeranschluss: Pinbelegung

– Leitung: Adernfarbe

Erst nach Anschluss aller elektrischen Verbindungen die Spannungsversorgung (U

V

> 0

V) anlegen bzw. einschalten.

Erläuterung der in Tabelle 1 bis 3 verwendeten Anschlussterminologie:

BN = braun

WH = weiß

BU = blau

BK = schwarz

n. c. = nicht angeschlossen

Q1 = Schaltausgang 1

Q2 = Schaltausgang 2

L+ = Versorgungsspannung (U

V

)

M = Masse

L.ON = hellschaltend

D.ON = dunkelschaltend

HINWEIS

Die Sensorausgänge sind möglicherweise mit einer werkseitig eingestellten EIN- und/

oder AUS-Verzögerung ausgestattet. Dies ist am Suffix Txx am Ende der Modellnummer

erkennbar (Zxx18-xxxxxxTxx).
