Summary
When using safety light curtains, you need to follow the correct steps to install, configure and maintain them, select the appropriate model, determine the location, accurately align and adjust the beam height. After connecting to the control system, set parameters and debug and optimize. Regular inspections and tests ensure long-term reliability of the equipment. Operators need to receive training to avoid misoperation and keep the equipment clean to ensure industrial safety.
The use of safety light curtains requires installation, configuration and maintenance in accordance with the correct steps to ensure their effectiveness and safety. The following are the steps and precautions for using safety light curtains:
Preparation for Installing the Safety Light Curtain
Selection and planning:
Choose the appropriate safety light curtain model according to the specific needs of the workplace. Factors to consider include the size of the protection area, the number and spacing of light beams, reaction speed, and environmental conditions (such as temperature, humidity, vibration, etc.).
Determine the installation location:
Determine the best installation location for the safety light curtain based on the range of activities of equipment and personnel. Generally, the safety light curtain should be installed at the entrance of the hazardous area to be protected to ensure that any person or object entering the area will be detected by the safety light curtain.
Safety Light Curtain Installation Process
Install the transmitter and receiver:
Mount the transmitter and receiver in the desired location. Make sure they are aligned accurately to ensure that the light beam can be stably transmitted from the transmitter to the receiver. The distance between the transmitter and the receiver should be consistent with the recommended distance in the product manual.
Adjust the height of the beam:
Adjust the height and density of the beam according to the protection requirements. The height of the beam should cover all possible access to the hazardous area to avoid missed detection.
Fixed installation:
Use brackets to fix the transmitter and receiver in the correct position. Make sure the installation is firm to avoid movement or vibration during operation, which will affect the effectiveness of the safety light curtain.
Before installation, please open the packing box first, check the packed components according to the packing list, and turn off the power supply of the machine tool at the beginning of installation to avoid danger.
1.Installation direction
The installation direction of the light emitting device and the light receiving device should be consistent.
2.Reflection from the ground and walls
When installing it as below, the light reflected from the surface of wall and flat is not shaded. Please check whether it operates normally or not with a sensing target before using.(interval distance: ≥ 0.5 m)
3.For protection of interference
It may cause interference when installing more than 2 sets of the sensor. In order to avoid the interference of the sensor, please install as following figures and use the transmitted light frequency changing function.
· Transmission direction should be opposite between 2 sets.
· Baffle should be installed between 2 sets.
· Interval distance adjustment:
① Depending on the environment, it may vary;
② Do not use it directly under high-speed and high-frequency fluorescent lamps.
Connection and Configuration of Safety Light Curtains
Connect to the control system:
Connect the safety light curtain to the machine's control system so that it can trigger a shutdown or other safety measures in time when the light beam is blocked. Configure the necessary interfaces and communication protocols according to the control requirements of the equipment.
Parameter setting:
Set the relevant parameters of the safety light curtain through the control unit or software interface, such as detection sensitivity, beam coverage, response time, etc. Make sure the settings are consistent with the actual application scenario.
Testing and Debugging of Safety Light Curtains
Initial test:
Before formal use, perform an initial test on the safety light curtain. By blocking the light beam to simulate the situation where a person or object enters the protection area, check whether the safety light curtain can correctly trigger the equipment shutdown or other safety measures.
Daily Use and Maintenance of Safety Light Curtains
Daily inspection:
Regularly check the alignment of the safety light curtain, the cleanliness of the light beam, and the stability of the connecting cables. Make sure that the transmitter and receiver are not blocked by dirt, dust or other objects.
Regular testing:
Repeat the function of the safety light curtain at regular intervals (such as weekly or monthly) to ensure that it can still work properly after long-term use.
Timely repair and replacement:
If the safety light curtain is found to be faulty or damaged, it should be immediately decommissioned and repaired or replaced. It should be tested again before use to confirm that it has returned to normal.
Precautions for Using Safety Light Curtains
Avoid misoperation:
Do not place irrelevant objects in the protection area of the safety light curtain to avoid accidentally triggering the shutdown or alarm system.
Keep clean:
Ensure that the surface of the transmitter and receiver is clean to avoid dust or oil from affecting the transmission of the light beam.
Train operators:
Ensure that all operators understand the working principle and use of the safety light curtain and know how to deal with safety measures after the safety light curtain is triggered.
