How to Use LAMP - STOP INDICATOR: Examples, Pinouts, and Specs

The LAMP - STOP INDICATOR (Model: XB4-BVM4), manufactured by Schneider, is a visual signaling device designed to illuminate and indicate a stop condition. It is widely used in industrial machinery, vehicles, and control panels to alert operators or drivers of a stop or emergency state. This robust and reliable component ensures clear visibility and enhances safety in various applications.

• Industrial Machinery: Indicates emergency stop conditions on control panels.
• Automotive Systems: Serves as a stop indicator in vehicles.
• Safety Systems: Alerts operators to halt operations in hazardous conditions.
• Control Panels: Provides visual feedback for stop commands in automation systems.

Below are the key technical details and pin configuration for the XB4-BVM4:

The XB4-BVM4 has a simple pin configuration for easy integration into circuits. Below is the pinout description:

1. Power Supply: Ensure a stable 24V DC power supply is available for the lamp.
2. Wiring:
   • Connect the Positive (+) pin to the positive terminal of the power supply.
   • Connect the Negative (-) pin to the ground terminal.
3. Mounting:
   • Securely mount the lamp on a panel using the provided mounting hardware.
   • Ensure the lens is visible and unobstructed for clear signaling.
4. Testing:
   • After wiring, power on the circuit to verify the lamp illuminates correctly.
   • Test the stop indicator functionality in the intended application.

• Voltage Compatibility: Ensure the power supply voltage matches the lamp's operating voltage (24V DC).
• Polarity: Double-check the polarity of the connections to avoid damage to the LED.
• Environmental Conditions: Install the lamp in environments within the specified operating temperature range and IP65 rating.
• Maintenance: Periodically inspect the lamp for dirt or damage to maintain optimal visibility.

The XB4-BVM4 can be controlled using an Arduino UNO for automation or testing purposes. Below is an example circuit and code:

• Connect the Positive (+) pin of the lamp to a digital output pin (e.g., Pin 9) on the Arduino through a 220-ohm resistor.
• Connect the Negative (-) pin of the lamp to the Arduino's GND.

// Example code to control the XB4-BVM4 Stop Indicator Lamp with Arduino UNO

const int lampPin = 9; // Pin connected to the Positive (+) terminal of the lamp

void setup() {
  pinMode(lampPin, OUTPUT); // Set the lamp pin as an output
}

void loop() {
  digitalWrite(lampPin, HIGH); // Turn the lamp ON
  delay(1000); // Keep the lamp ON for 1 second
  digitalWrite(lampPin, LOW);  // Turn the lamp OFF
  delay(1000); // Keep the lamp OFF for 1 second
}

1. Can the lamp operate on AC power?

   • No, the XB4-BVM4 is designed for 24V DC operation only.

2. What is the lifespan of the LED?

   • The LED has a typical lifespan of 50,000 hours under normal operating conditions.

3. Can the lamp be used outdoors?

   • Yes, the IP65 rating ensures it is suitable for outdoor use, provided it is not submerged in water.

4. What resistor value should I use with an Arduino?

   • A 220-ohm resistor is recommended to limit the current and protect the lamp.

By following this documentation, users can effectively integrate and maintain the XB4-BVM4 Stop Indicator Lamp in their applications.
