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.

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.

11
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.

16 Montage
Den Sensor an einen geeigneten Befestigungswinkel montieren (siehe SICK-Zubehör-
Programm).
Bevorzugte Ausrichtung des Sensors relativ zur Bewegungsrichtung des Objekts beach‐
ten, siehe Abbildung 21.

17 Elektrische Installation
Anschluss der Sensoren muss spannungsfrei (U
V
= 0 V) erfolgen. Je nach Anschlussart
