INSET RUNWAY EDGE LIGHT SLRE
INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
1GENERAL
SLRE Semi-flush runway edge light is high intensity, uni-bidirectional, inset, 12”
steady-burning type.
These fixtures are intended for use as runway edge or threshold\end, in order to
provide a visual aid to the moving aircraft.
SLRE lights are in compliance with ICAO Annex 14 Vol.1, FAA AC 150/5345-46 (Style
2), IEC TS 61827 (Style 3) and STANAG 3316.
The fixtures described in this manual are designed to be connected to series circuit,
fed through standard isolation transformers connected to CCR with variable current
from 2.8 A to 6.6 A.
Location of these fittings shall be in compliance with ICAO –Annex 14, STANAG 3316
and FAA.
2MAIN FEATURES
Each light assembly consists of a removable fixture and a shallow base receptacle.
The fixture is waterproof and designed to withstand aircraft impact and roll-over
loads without damage.
The fixture can be bidirectional type (bidirectional dome provided with two optical
windows and equipped with two lamps that can operate simultaneously or in
independent way) or unidirectional type (unidirectional dome provided with one
optical window and equipped with only one lamp); it is also possible to obtain an
unidirectional light from a bidirectional dome choosing the ‘X – Screened’ option (see
Figure 3); this configuration includes a bidirectional dome and a screen to blind the
unused optical window.
2.1 REMOVABLE LIGHT UNIT
The removable fixture mainly consists of a dome, an optical assembly and a lower
cover.
2.1.1 Dome
The dome is made of treated aluminium casting and includes one or two windows to
seat the prisms, complete with gaskets, kept in the proper position by means of a
mounting plate fixed with three screws HSFH M5x12. In correspondence of the
windows, the dome is outside provided with identification letters “A”, “B” and “C”.
Opposite apertures are parallel to the centerline axis and the different toe-in of the
lamps give the correct light beam depending on the kind of fixture: runway edge or
threshold\end light.

Edition 11/03/2014 Supersedes edition 04/30/2012
INSET RUNWAY EDGE LIGHT SLRE
INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
The shallow base installation becomes very easy because no precise toe-in is required
during civil.
The dome is provided with six through holes for fastening the light unit to the base
and two suitable slots, in opposite position, to make easy the fixture removal by
using two suitable lifting tools (available on request, P/N 332.4140 or 332.4230). As
alternative, two screwdrivers can be used.
A silicone O-Ring (separately supplied) has to be mounted outside around the dome,
to avoid dirt deposits between dome and shallow base.
2.1.2 Optical Assembly
The optical assembly (bidirectional) consists of two prisms (Figure 1 - n°3) with
relevant gaskets (Figure 1 - n°4), one or two filters with relevant holder, when
required, (Figure 1 - n°8-9) and one or two lamps (Figure 1 - n°13). Unidirectional
fixtures mount only one lamp, one prism and one filter, when required.
Fixtures can be provided with six kinds of lamp supporting plate in order to obtain
the following configurations:
ICAO 45 m and 60 m ("C"+"A") (P/N 152.9025)
ICAO 45 m and 60 m ("C"+"B") (P/N 152.9085)
FAA green-red ("C"+"A") (P/N 152.9141)
FAA green-red ("C"+"B") (P/N 152.9151)
FAA red-red ("C"+"A") (P/N 152.9161)
FAA red-red ("C"+"B") (P/N 152.9171)
The lamp is of tungsten-halogen type, rated 105 W 6,6 A, 1500 hours average lamp
life, with dichroic reflector and male faston plug wires. The lamp is locked into its seat
by a single elastic holder (stainless steel) in order to realize an easy and quick lamp
replacement.
All the optical assembly parts are factory assembled; they may be field-replaced if
necessary.
2.1.3 Lower Cover
The lower cover consists of a treated aluminium casting; it is fastened to the dome
by means of three screws HSCH M5x16. An O-Ring is provided between dome and
lower cover.
The cover is provided with one or two threaded holes for cable entry and external
grounding screw with yellow-green cable lead, size 2.5 mm2, 0.460 m long, with male
faston terminal. A suitable valve is outside mounted for the leakage test.

INSET RUNWAY EDGE LIGHT SLRE
INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
Watertightness between fixture and shallow base is ensured by means of an O-Ring
(separately supplied) to be placed on the relevant groove around the lower cover.
The fixture is supplied with one or two cable leads with L-823 plug; each of them
consists of two single-pole teflon leads, size 2.1 mm2 (#14 AWG), 0.700 m long. The
plug is in compliance with FAA AC 150/5345-26 for very quick coupling with the
receptacle mounted on the shallow base.
The fixture is 304 mm in diameter and 123 mm (+ 18,5 mm for plugs) high; the
protrusion above the ground is less than 12.7 mm.
An identification data label is externally applied over the lower cover (Figure 1 -
n°30). Moreover, to identify quickly the beam colour, the letters “A”, “B” and “C” of
the dome in front of the windows are painted in the same colour of the light beam.
The same colour painting is provided outside on the lower cover.
See “Complete P/N identification” figure for P/N information.
All hardware is made of stainless steel.
