Pn note
Corrected: XB4BVB4 = red, 24V AC/DC (se.com). Was mislabeled 230V (bogus -230 suffix). XB4-BV voltage letter B=24V (G=110-120V, M=230-240V). AUDIT other XB4-BV*-230 entries.
Pn status
voltage-corrected

Installation Quick Reference

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.

Troubleshooting

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.
