Nice XBA4 warning lights for 4 m oval boom, LED

The Nice XBA4 are warning lights for a 4 m barrier boom. According to the Nice catalogue, they clip onto the top or bottom of the boom. This makes the boom more visible, especially at night. They are used with the Nice S4BAR, M3BAR, M5BAR, Wide S and Wide M barriers. For longer booms there are the XBA6 lights (6 m).

Wiring according to the M-BAR manual

1. Put the boom in the vertical position, unscrew the boom cover and temporarily remove the boom.
2. Thread the cable gland through the prepared hole and insert the light cable inside the protective rubber.
3. Shorten the cable only at the marked points and close the end with an end cap.
4. Route the cable through the boom holder into the housing, leaving slack for the boom to rotate, and connect it to the LIGHT terminal.

What to bear in mind

The LIGHT output is polarised. If the lights do not come on, swap the wires. On the S4BAR, according to the manual, the lights reduce the number of cycles from 100 to 80 per hour. Questions to eshop@saver.sk.
