ADB Safegate REIL-L, User Manual

Page: 25 / 60

•
The beam centerline of each light unit is aimed 15 degrees outward from a line parallel to the runway centerline and
inclined at an angle of 10 degrees above the horizontal.
•
If REILs are used with a PAPI, install REILs 75 feet from the runway edge.
Figure 2: Typical Layout for REIL
A. The optimum location for each REIL light unit is in line with the runway threshold at 40 feet (12.1m) from the runway edge.
A variance of 100 feet (30.4m) upwind and a 30 feet (9.1m) downwind longitudinal tolerance is permitted from the runway
threshold in locating the REIL light units.
B. Space the light unit equally from the runway centerline. When adjustments are necessary, the difference in the distance of
the units from the runway centerline shall not exceed 10 feet (3m).
C. The beam centerline (aiming angle) of each light unit is aimed 15 degrees outward the line parallel to the runway centerline
and inclined at an angle of 10 degrees above the horizontal. If angle adjustments are necessary, provide an optical baffle and
change the angles to 10 degrees horizontal and 20 degrees vertical.
D. Both units elevation are placed within 3 feet (0.9m) of the horizontal plane through the runway centerline.

3.4 Tools and Test Equipment
Conventional tools and test equipment used by general and electrical contractors should suffice for installation. However, a
true RMS multi-meter such as a Fluke 87V (or equivalent) and a clamp-on amp probe should be available. A waterproof
shroud is needed if a cabinet door has to be opened in extremely inclement weather.
3.5 Installation of the Control Cabinets
Unpack the individual cabinets, and open the cabinet doors by depressing the "red" button at the bottom of the door lever
and then insert a medium width bladed screw driver in the slot and rotate the screwdriver counter clockwise and turn the
handle, approximately ¼ turn clockwise to unlock and open the door.
Note
The ADB Safegate LED L-849V/I, style A and E REIL uses the same enclosure for both the Primary and Secondary Units.
