XB4-BVB3
현행 제품ATEX Green Indicator Light 24V
Schneider Harmony XB4 ATEX-certified green pilot light for Zone 1/21 hazardous areas.
일반적인 용도
Found on control panels in oil refineries, chemical processing plants, and offshore platforms. The ATEX Zone 1 certification means it can operate where explosive gas is likely present during normal operation. Green indicates process running or system OK.
사양 목록
|
ATEX Zone
The hazardous area classification. Zone 1 = gas likely present. Zone 2 = gas unlikely. Zone 21/22 = combustible dust.
|
Zone 1, Zone 21
|
|
Certifications
Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.
|
ATEX, IECEx, CE
|
|
Color
Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).

Cutout Diameter
The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.
|
22mm

|
Explosion Group
The gas group the device is certified for. IIC covers hydrogen (most restrictive). IIB covers ethylene. IIA covers propane.

LED Voltage
The voltage required for the built-in LED. Must match your control circuit voltage (typically 24V DC or 230V AC).
|
24V AC/DC
|
|
Temperature Class
Maximum surface temperature. T6 (85°C) is most restrictive. T1 (450°C) is least. Must not exceed auto-ignition temp of the gas.

추가로 필요한 부품
이것은 모듈형 부품입니다. 완전한 조립을 위해 다음이 추가로 필요할 수 있습니다:
설치 빠른 참조
Panel cutout: 22mm. Insert from the front, secure with mounting nut.
LED module: Check the voltage rating matches your supply (typically 24V DC or 230V AC). Connect to PLC digital output or relay contact for status indication.
Color meaning (IEC 60204-1): Green = normal/running. Red = fault/danger. Yellow = warning/caution. Blue = mandatory action. White = neutral/general.

문제 해결
Light is dim or flickering
Check supply voltage matches the LED module rating. Low voltage causes dimming. If voltage is correct, the LED module is failing — replace it. LED modules have finite life (typically 50K-100K hours).
Light doesn't turn on
Verify voltage at the terminals with a multimeter. Check the PLC output or relay driving the light. LED modules are polarity-sensitive on DC circuits — try reversing the leads.
