During the warranty period, if the product is damaged due to the following conditions, repair fees will be charged.

1. Product damage caused by not operate the product according to the regulations in the manual.
2. Product damage caused by fire, flood, and abnormal voltage.
3. Product damage caused by abnormal functions.
4. Product damage caused by exceeding the specified scope of use of the product.
5. Secondary damage caused by force majeure (natural disaster, earthquake, lightning).

Responsibility statement

The contents of the manual have been carefully checked, but there is no guarantee that it is completely correct. We will regularly check the content of the manual and make corrections in subsequent versions. Valuable opinions are welcome. The contents described in the manual are subject to change without notice.

The relevant service fees shall be calculated according to the unified standards of the manufacturers. If there is a contract, the principle of contract priority shall be used. Please refer to Warranty Card for detailed warranty instructions.

Installation precautions

WARNING

To ensure safety system operation, please configure emergency braking circuit, positive inversion circuit or other protection circuit for PLC, which can prevent the damage to PLC or other devices.

● It is imperative to configure the relevant safety circuits externally to the programmable controller.

● All outputs are turned off, as an error be detected by PLC CPU during self-diagnosis, such as a watch dog timer error. When error that cannot be detected, internal protection circuit may be disabled.

When relay and transistor are damaged, the output state of transistor in the PLC can’t be controlled. To ensure safe operation of the machine, please design external protection circuits and mechanisms for key output signals.

Start-up and maintenance precautions

DANGER

● Do not touch the terminal when power-on, otherwise it may cause electric shock and misoperation.

● Please remove and clean the terminal after the power is off. Otherwise, it may cause electric shock when power-on.

● Please read the manual carefully and confirm the safety before performing program changes, forced output, RUN, STOP and other operations during machine running.

● Mistakes in operation will damage the machine and cause accidents.

WARNING

● Please do not decompose and transform, otherwise it will cause failure, malfunction and fire.

※ For maintenance matters, please contact FUJIAN FUCAN Wecon Electronic Technology Co., Ltd.

● Please load and unload the extension cable and other connecting cable after the power is turned off, otherwise it will cause failure and malfunction.

Maintenance and repair

Periodic inspection

1. Whether the temperature inside the machine has risen abnormally due to other heating elements or direct sunlight.
2. Whether there is dust or conductive dust intrusion into the machine.
3. Whether there are loose wiring and terminals and other abnormalities.

Appearance and size

✎Note:

Fast Flashing: ON for 100ms, OFF for 100ms;

Flashing: ON for 200ms, OFF for 200ms;

Single flash: ON for 200ms, OFF for 1s.

1. The USB interface used to be only for firmware upgrade or debugging of the coupler itself and cannot supply power to expansion modules.If expansion modules are connected to the system, power must be supplied via the 24V power input interface; otherwise, the modules cannot be recognized.
2. It is strictly prohibited to power the system via USB when expansion modules are connected. 

Installation instructions

Please install the end cover on the right side of the last expansion module, align it with the module interface slot and connect it, as shown in the figure below:

The figure below takes the LX6V-EMC-PN coupler as an example

Electrical installation

Communication wiring

Cable recommendation

Profinet communication uses STP/FTP cable for network data transmission, without short circuit, dislocation and bad contact. 

The length of the cable between the devices cannot exceed 100 meters. Exceeding 100 meters will cause signal attenuation and affect normal communication.

It is recommended to use the following specifications of data cables:

 Wiring instructions

Refer to the shell mark for wiring, the IN interface is EtherCAT input port, used for connecting the EtherCAT master station; The OUT interface is an EtherCAT output port, used for connecting the later EtherCAT slave station.

Power terminal wiring

Connect the 24V power supply positive and negative poles according to the shell mar. The cross-sectional area of the grounding wire shall be not less than 2 mm², and the grounding resistance shall be less than 100 Ω.
