- Page 10 Installation Method Precautions Regarding Surrounding Reflective Surfaces When there are metal plates, workpieces, glass, partitions, or other reflective surfaces around the light curtain, the distance B between the light curtain and the reflective surface must not be less than A, as illustrated in the diagram. The calculation formula for A is as follows: In this context, represents the detection distance of the light curtain, measured in meters (m);...
- Page 11 ● The working power supply for the SE4 type safety light curtain should not exceed 24 V + 20%, as this may affect the stability of the SE4.

Page 12: Safety Output
Once the internal control circuit receives a feedback signal (off signal) based on the self-diagno- sis, the SE4 determines that its output circuit is operating normally. If this off signal is not returned to the internal control circuit, the SE4 judges that there is a problem in its output circuit or wiring and enters a fault state. - Page 13 Product Commissioning and Maintenance Product Commissioning Steps ● Assemble the Bracket Fix the bracket onto the product, ensuring there is an appropriate amount of adjustability. ● Secure the Bracket Secure the bracket in a location that ensures the safety light curtain can effectively perform its protective function, as per installation requirements.

- Page 16 Noun explanation Routine Maintenance of the Product When any beam is obstructed by an object, it will cause the receiver to receive an occlusion signal, as shown in the diagram. Beam Center: The optical path between the emission optical center and the reception optical center. Beam Spacing: The distance between the centers of two adjacent beams.
- Page 17 Infrared Configuration Function Overview SE4 type safety light curtains support an infrared remote control configuration function across the entire series. This function allows users to install the " Configuration Assistant" app on a smartphone with infrared remote control capabilities or purchase a matching infrared remote control device for configuration purposes.
- Page 18 Infrared Configuration Function The Usage Instructions for the Mobile App Transmiter Receiver Enter Configuration MessageBox Not supported infrared remote control Exit Configuration ● Configuration Steps ● Select the Sensor for Configuration: Open the “Configuration Assistant” app and choose either the transmitter or receiver to enter the corresponding configuration interface.
- Page 19 Function Explanation: Output mode switching is generally used for quick adjustment when the selected SE4 safety light curtain does not match the control method at the application site. After switching the output mode, the SE4 safety light curtain must undergo safety confirmation and inspection before being put into use.
- Page 20 Infrared Configuration Function Explanation of Configurable Functions ● The transmitter and receiver of the same set of SE4 safety light curtains must use the same optical synchronization channel. ● Switching back to the long-distance mode from the close-range mode may result in the SE4 safety light curtains not being able to detect light.
