Installing and wiring a banner light curtain is a crucial aspect of any industrial automation system. It ensures the safety of personnel and equipment by preventing hazardous situations. In this article, we will discuss the wiring of a banner light curtain and provide a comprehensive guide on how to properly do it.
What is a Banner Light Curtain?
A banner light curtain is a safety device that uses infrared light to detect the presence of objects in its field of view. It is commonly used in production lines, packaging, and other industrial environments to create a protective barrier around hazardous machinery. The curtain comprises a transmitter and receiver unit that sends and receives an infrared beam. When the beam is interrupted, the device sends a signal to the control system, triggering an emergency stop.
Components of a Banner Light Curtain
A banner light curtain consists of several components, including:
| Component | Description |
|---|---|
| Transmitter Unit | Sends out an infrared beam |
| Receiver Unit | Receives the infrared beam and sends a signal to the control system |
| Control Unit | Processes the signal from the receiver unit and triggers an emergency stop when necessary |
| Power Supply | Supplies power to the banner light curtain components |
Wiring a Banner Light Curtain
Wiring a banner light curtain requires a basic understanding of electrical circuits and a knowledge of the device’s components. The wiring process involves connecting the transmitter and receiver units to the control unit and power supply. Here are the steps to follow when wiring a banner light curtain:
Step 1: Mount the Banner Light Curtain
Before wiring the banner light curtain, mount it on the equipment you want to protect. Ensure that the curtain is installed at a height that provides maximum coverage and that the transmitter and receiver units face each other.
Step 2: Connect the Transmitter and Receiver Units to the Control Unit
The transmitter and receiver units should be connected to the control unit using a shielded cable. Connect the transmitter unit to the input of the control unit and the receiver unit to the output of the control unit. You can check the wiring diagram provided by the manufacturer to ensure that you connect the units correctly.
Step 3: Connect the Control Unit to the Power Supply
The control unit should be connected to a power supply unit using a separate power cable. Connect the power supply unit’s positive and negative terminals to the control unit’s corresponding terminals.
Step 4: Test the Banner Light Curtain
After completing the wiring process, test the banner light curtain to ensure that it is working correctly. Start by checking the control unit’s LED indicators. The green LED should light up when the device is powered on, and the yellow LED should light up when an object interrupts the infrared beam. You can also test the banner light curtain by placing an object in its field of view and observing whether it triggers an emergency stop.
