3 Intended use

The ZLD18 / ZLE18 is an opto-electronic photoelectric retro-reflective sensor (referred

to as “sensor” in the following) for the optical, non-contact detection of objects, ani‐

mals, 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.

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

ZLD18-xxxxx2, ZLD18-xxxxx8, ZLE18-xxxxx2, ZLE18-xxxxx8: align the sensor with a suitable

reflector. Select the position so that the red emitted light beam hits the center of the reflec‐

tor. The sensor must have a clear view of the reflector, with no object in the path of the

beam [see figure 2]. Ensure that the optical openings of the sensor and reflector are com‐

pletely clear.

9

Figure 2: Alignment

2 Sensing range

Adjust the distance between the sensor and the reflector according to the corresponding

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

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

table 1 to check the function. If the switching output fails to behave in accordance with

table 1, check the application conditions.

3 Sensitivity setting

Sensor not possible to be set: The sensor has been adjusted by the factory to provide maxi‐

mum sensitivity 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 light beam is

aligned to the reflector and

there is no object in the path of

the beam

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

Signal interruptions when

object is detected

Depolarizing property of the

object surface (e.g., tape),

reflection

Change the position of the

sensor

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.

14 Bestimmungsgemäße Verwendung

Die ZLD18 / ZLE18 ist eine opto-elektronische Reflexions-Lichtschranke (im Folgenden

Sensor genannt) und wird zum optischen, berührungslosen Erfassen von Sachen, Tie‐

ren und Personen eingesetzt. Zur Funktion wird ein Reflektor benötigt. Bei jeder ande‐

ren Verwendung und bei Veränderungen am Produkt verfällt jeglicher Gewährleistungs‐

anspruch gegenüber der SICK AG.

16 Montage

Sensor und Reflektor an geeignete Befestigungswinkel montieren (siehe SICK-Zubehör-

Programm). Sensor und Reflektor zueinander ausrichten.

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).
