procedures before using the product.
LCS
Ⅱ
should only be installed, checked, and maintained by a
qualified person. A qualified person is defined as “a person or
persons who, by possession of a recognized degree or certicate
of professional training, or who, by extensive knowledge, training
and experience, has successfully demonstrated the ability to solve
problems relating to the subject matter and work” .
OSSDs must satisfy the following conditions:
Not short-circuited with 24V
The OSSDs should not be used with a current that is higher than
the rating.
Do not drop the product.
Dispose of the product in accordance with the relevant rules and
regulations of the country or area where the product is used.
The user should establish the rules and regulations for safe
operation and carry out them eectively.
Applications
LCS
Ⅱ
designed for industrial automation specially, the typical applications
are as follows: automated assembly production lines, industrial robots,
packaging equipment, automation equipment, welding lines, and so on.
LCS
Ⅱ
can only detect objects which intrude into the detection zone.
Detection zone is the rectangular area between the emitter and the
receiver, formed by protective height and operating range.
LCSII can onlycannot detect transparent and/or translucent objects.
The size of the guarded object must not be less than the detection
capability. Detection capability is the sensing function parameter limit
specied by the supplier that will cause actuation of the system.
1. System components
LCSII is composed of an emitter, a receiver and two transmission cables, as
shown in the following gure.
2. Appearance
LCSII is composed of emitter and receiver, using the outlet mode integrated
in the end cap, connecting to the external signals with high exible cable,
shown in the following gure.
LED Indicator Colour Description
Emitter
POWER Yellow Turns on while the power is on.
FAULT Red
Turns on when the system is in fault state or the
communication is wrong. The OSSDs output OFF-
state and the guarded machine can’t work.
LINK Blue Turns on while there is communication between
emitter and receiver.
End cap
indicator Red/Green
Display green when the OSSDs output ON-state,
display red when the OSSDs output OFF-state or
the system is in fault state.
Receiver
POWER Yellow Turns on while the power is on.
ON Green Turns on when the OSSDs output ON-state. The
guarded machine works.
OFF Red Turns on when the OSSDs output OFF-state and the
guarded machine can’t work.
FAULT Red
Turns on when the system is in fault state. The
OSSDs output OFF-state and the guarded machine
can’t work.
End cap
indicator Red/Green
Display green when the OSSDs output ON-state,
display red when the OSSDs output OFF-state or
the system is in fault state.

4. Transmission cable
The transmission cable is used for signal transmission between the sensor
and the control circuit of the guarded machine. Transmission cable is
divided into standard cable and high exible cable, high exible cable can
be used in frequently moving occasions.
The standard length of transmission cable is 2m, 3m, 4m, and 5m.
The connection points are shown in the gure below.
Transmission cable is the 6-core butyl sheath shield cable, with the
waterproof plug at one end connected with the sensor and the other end
connected to the guarded machine.
If the standard transmission cable can not meet the requirements of the
use, the extension cable can be used to increase the length of transmission
cable. Extension cable is divided into standard cable and flexible cable,
high exible cable can be used in frequently moving occasions.
Extension cable is the 6-core butyl sheath shield cable, with the hole
seat at one end and the pin seat at the other end. The standard length of
transmission cable is 5m, 10m and 20m. The picture is as follows:
The number, color and function of the cores are shown in following table.

label Meaning of signal Wiring
1 Yellow CANH communication signal Connect CANH between emitter and receiver
2 Green Cathode of input DC24V Connect with cathode of input DC24V
3 Black NPN control output interface Control output interface 1
4 Blue CANL communication signal Connect CANL between emitter and receiver
5Red Anode of input DC24V Connect with anode of input DC24V
7 Brown PNP control output interface Control output interface 2
Yellow/
Green Shield layer Short circuited with the cathode of power
supply negative short and connect
Note: LCSII integrates NPN and PNP outputs together , while black wire is for NPN interface
and brown wire is for PNP interface.
