Vertical bars: Cuts of the individual lines, corresponds to the encoder resolution.
Blue square marks: Clear and contrast-rich pattern areas automatically selected by the

Function
The PS30 pattern sensor is an opto-electronic sensor that detects recurring patterns in
a contactless manner.
The principle of operation is based on a line camera which constantly searches for con‐
trast differences and sharp edges in the print image (see figure). These distinct and
unique areas in the pattern are automatically selected by the sensor during the teach-in
process. If the image and contrast pattern stay the same, these points will be in exactly
the same locations. The sensor evaluates grayscale information.
A taught-in image is used as a reference for the subsequent detection of a recurring
contrast pattern. The print marks usually used for determining position are no longer
necessary. When a pattern matching the reference pattern is identified, a switching out‐
put is initiated.
The PS30 pattern sensor requires for its operation information about the speed of the
material, e.g., from encoder pulses, from a motor feedback system, or as a defined vari‐
able with a fixed value or a value updated via TCP/IP.
3.3 Operating modes
The PS30 pattern sensor can be operated in one of two modes:
1 Endless material
2 Single object
3.3.1 Endless material operating mode
When further processing endless materials such as film and paper webs to produce, for
example, labels and packaging with a constant repeat length, exact determination of
position is essential, e.g., to determine the cut position.
12
Typically, the target cut position is selected as the start point of the reference image,
and the reference image is terminated before the end of the repeat length. The start
point of the teach-in area is the position of the switching signal. A switching point offset
can also be configured.

3.3.2 Single object operating mode
In this case the position is to be determined for repeating, separate objects with identi‐

is taught in as a reference.
The end of the teach-in area is used as the position for outputting the switching signal.
A switching point offset can be defined.

•
If fewer than 3 bars are flashing: check whether the signal is switching correctly. If
•
the signal is not switching correctly, repeat the teach-in process.
Process quality
When the RUN symbol is lit up, the number of bars indicates the process quality.
If 2 or fewer bars are flashing: check whether the signal is switching correctly.
•

The electrical installation must only be performed by electrically qualified person‐
nel.
■
Standard safety requirements must be met when working on electrical systems!
■
Only switch on the supply voltage for the device when the connection tasks have
been completed and the wiring has been thoroughly checked.
■
When using extension cables with open ends, ensure that bare wire ends do not
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be appropriately insulated from each other.
■
Wire cross-sections in the supply cable from the user’s power system must be
selected in accordance with the applicable standards.
■
Only operate the device with an LPS (limited power source) in accordance with IEC
60950-1 or an NEC Class 2 power supply unit.
■
All circuits connected to the device must be designed as SELV/PELV circuits.
■
Operation in short-circuit protected network at max. 8 A.
NOTE
Layout of data cables
■
Use screened data cables with twisted-pair wires.
■
Implement the screening design correctly and completely.
■
To avoid interference, e.g., from switching power supplies, motors, clocked drives,
and contactors, always use cables and layouts that are suitable for EMC.
■
Do not lay cables over long distances in parallel with voltage supply cables and
motor cables in cable channels.
20
The IP enclosure rating for the device is only achieved under the following conditions:
■
The cables plugged into the connections are screwed tight.
■
Any other covers present must be closed and lie flush on the device.
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!

6.2 Wiring notes
ELECTRICAL INSTALLATION
NOTICE
Faults due to incorrect wiring!
Incorrect wiring may result in operational faults.
■
For data transmission, use only shielded cables with twisted-pair wires.
■
Follow the wiring notes precisely.
NOTE
Preassembled cables can be found online at:
www.sick.com/PS30
b
All electrical connections of the device are configured as M12 round connectors. The
enclosure rating is only achieved with screwed plug connectors or cover caps.
Please observe the following wiring notes:
■
A correct and complete cable shielding design is required for trouble-free data
transmission.
■
The cable shield must be connected at both ends in the control cabinet and at the
device. The cable shield of the pre-assembled cables is connected to the knurled
nut of the male/female connector and thus also to a large area of the device hous‐
ing.
■
The cable shield in the control cabinet must be connected to a large area of the
signal ground, see figure 17.
■
Appropriate measures must be taken to prevent equipotential bonding currents
flowing through the cable shield.
■
During installation, pay attention to the different cable groups. The cables are
grouped into the following four groups according to their sensitivity to interference
or radiated emissions:
6
Group 1: Cables very sensitive to interference, such as analog measuring
°
cables
Group 2: Cables sensitive to interference, such as sensor cables, communi‐
°
cation signals, bus signals
Group 3: Cables which are a source of interference, such as control cables
°
for inductive loads, motor brakes
Group 4: Cables which are powerful sources of interference, such as output
°
cables from frequency inverters, welding system power supplies, power
cables
w
Cables in groups 1, 2 and 3, 4 must be crossed at right angles, see figure 14.
w
Cables in groups 1, 2 and 3, 4 must be routed in different cable channels or
metallic separators must be used, see figure 15 and see figure 16. This
applies particularly where cables of devices with a high level of radiated emis‐
sion, such as frequency converters, are laid parallel to sensor cables.
