General:
The EASA/EASB/EASC luminaires are fairly simple in construction and wiring. Major components are
the main housing, light engine (LED Board), and power door. The power door is designed to be field
replaceable. Any light engine is considered to not be failed until 10% or more of LEDs do not
operate. Typical troubleshooting details follow. EASx products may have one or two light engine
assemblies in the optical cavity and one or two drivers on the power door assembly.
Section 1: Light Engine(s) Out
1. Visually check operation of unit
2. If either the front or rear (asymmetric distributions)
or right or left (symmetric distributions) light
engine is not functioning do the following.
A. Disconnect and isolate fixture
from power source (lock out
incoming power to the pole).
B. Open power door by
loosening the captive screws.
*This is a typical representation of a right-left light engine orientation.
Orientation, LED count and optical components will vary according to light
distribution.
