Thoroughly read this manual and understand the installation
procedures, operation check procedures, and maintenance
procedures before using the product.
Ⅱ
●
LCS 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 certificate
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 effectively.

Applications

Ⅱ
LCS 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.
Ⅱ
LCS 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
specified 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 figure.

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 flexible cable,
shown in the following figure.
LED Indicator Colour Description
POWER Yellow Turns on while the power is on.
Turns on when the system is in fault state or the
FAULT Red communication is wrong. The OSSDs output OFF-
state and the guarded machine can't work.
Emitter
Turns on while there is communication between

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 flexible cable, high flexible 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 figure 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 flexible 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.
