3. Struktur & Verkabelungsanweisungen

3.1 Terminaldefinition

The base is equipped with only 2 wiring terminals X1 and X2, non-polarized for AC supply

X1: Live wire L

X2: Neutral wire N

AC circuits have no polarity; connecting the two terminals to any position of a 220V circuit will light up the red pilot light.

3.2 Montageverfahren

1. Drill a Φ22.5mm round hole on the control cabinet panel, insert the pilot light body from the front side of the panel;
2. Fit the lock nut onto the rear side and tighten manually for fixation;
3. Connect control wires to terminals X1 and X2 on the base, then fasten wire clamping screws;
4. Switch on power to test steady illumination.
5. Anwendungsszenarien
6. Standard application for red lights: Equipment fault alarm, emergency stop circuit indication, overload warning, shutdown alert;
7. Compatible equipment: SPS-Schaltschränke, Luftkompressoren, Werkzeugmaschinen, Produktionslinien, Wasserpumpe & fan control boxes;
8. Schaltungstyp: Mains AC 220V control circuit, no intermediate transformer required.
9. Cross-Series Selection Reference Table

24V low-voltage alternative model: XB2-BVB4LC (Rot, 24V AC/DC)

6. Fehlerbehebungsmatrix

7. Safe Operation Specifications
8. Strictly prohibit direct connection to 380V supply, which will burn out the LED instantly; select XB2-BVQ4LC for 380V circuits;
9. Recommended wire: 0.75~1.5mm² solid copper wire;
10. Install cabinet sealing gaskets for humid control cabinets and outdoor enclosures to maintain IP66 protection;
11. Designed solely for status indication, unable to carry high-power loads; no contact output function;
12. Do not strike or grind the lens cover; scratches will drastically reduce light transmittance and protection performance.
13. Order & Packaging Information

Individually packed per unit; standard packaging: 5 pieces per small box, 100 Stück pro Karton

Spare Parts: No separate LED chip spares available; replace the complete pilot light assembly if damaged

Conclusion on Color Replacement for Schneider XB2-BVM4LC (XB2BVM4LC)

1. Official Factory Conclusion: The lens cover and LED color cannot be replaced separately
2. The XB2-BVM series adopts an integrated non-detachable sealed structure (lens cover, colored LED chip, 220V current-limiting circuit and base housing are integrally injection-molded).
3. Schneider official FAQ clearly states: The internal LED module of integrated XB2 pilot lights cannot be disassembled separately, and colored lens covers or LED components are not sold as separate spare parts. Only illuminated pushbuttons with split bases support LED core replacement; this all-in-one light does not allow color component replacement.
4. Illumination principle: The lens cover itself is transparent, with a built-in red LED chip (color is not generated via colored filter lenses). Even if the lens cover is forcibly unscrewed, the internal light source remains red and color modification is impossible.
5. Two On-Site Color Modification Solutions

Lösung 1: Direct Full Unit Replacement (Empfohlen, Compliant, Factory Standard)

Purchase complete units of target color with the same AC 220V voltage; no wiring modification required, compatible with standard panel cutouts:

Weiß: XB2-BVM1LC

Grün: XB2-BVM3LC

Gelb: XB2-BVM5LC

Blau: XB2-BVM6LC

Ersatzschritte: Cut off power → Loosen rear lock nut on panel → Remove old red light → Install new colored pilot light → Tighten lock nut and restore wiring.

Lösung 2: Temporary Emergency Fix (Only for short-term maintenance, not recommended for long-term equipment operation)

1. External colored film: Attach high-temperature resistant translucent colored film to lens surface. Drawbacks: Reduced light transmittance, accelerated aging due to heat, degraded IP protection rating;
2. Translucent colored spray coating inside lens cover: Permanently destroys factory IP66 protection rating; water vapor ingress easily triggers short circuits and fails equipment acceptance standards.
3. Distinction Between Two Easily Confused Products (To Avoid Wrong Selection)
4. XB2-BVM Integrated Pilot Light (This Model): Non-replaceable color, integrated encapsulation, no separate LED core spares;
5. XB4 Series Pilot Light / XB2 Split Illuminated Pushbutton: Modular design with separately replaceable LED heads for free color switching, suitable for cabinets requiring frequent color adjustments.
6. Ergänzende Hinweise
7. Mandatory voltage matching: The original XB2-BVM4LC is rated AC 220V; only models with suffix M (220V) are acceptable for replacement. Models with suffix B (24V) or Q (380V) cannot be used;
8. Safety standards compliance: Red/Green/Yellow pilot lights on industrial equipment correspond to fault/Running/pre-alarm status. Unauthorized long-term color modification via film violates machine tool and power distribution safety standards and will fail acceptance inspection;
9. Ersatzteilbeschaffung: No separate lens or LED spares; only complete pilot light assemblies can be ordered as replacements.
