General information

Siemens Airfield
Solutions 12” FRange inset
lights

The Siemens Airfield Solutions 12” F-Range Inset Lights are light fixtures which
provide optimum visual guidance with minimal maintenance, low life-cycle costs
and maximum reliability. They are designed to withstand the high impact and rollover loads imposed by today's widebody aircraft during landing and take-off
operations while remaining waterproof and serviceable.
The 12” F-Range fixtures are shipped ready for installation on FAA L-868 deep
bases with an adapter ring (see “Overview of FAA deep bases and Siemens Airfield
Solutions adapter rings” page 13). An alternate approach to mounting the F-Range
fixtures is to install them on L-868C or on LB1/4/4A bases using an adapter ring.
Contact Siemens Airfield Solutions Sales Department for shallow base mounting
options.
The 12” F-Range family types are intended for the following uses:
• L-850D: Combined Threshold and Runway End
• L-850E: Threshold and Threshold Wing Bars
• FEN: Runway End (not submitted for FAA certification)
• FAP: Approach Centreline and Side Row Barrettes (not submitted for FAA
certification)

Purpose of this
manual

This manual describes procedures for the installation, maintenance and
troubleshooting of the 12” inset light family.

Scope of this
manual

This manual covers the light fixtures manufactured in accordance with FAA
specification AC 150/5345-46B and the photometric requirements of the latest
edition of ICAO Annex 14. Operation beyond the design limitations of these
specifications may result in degradation of performance, damage or failure of
components or hazardous conditions.

General Information and Requirements

Equipment data
Equipment
supplied

Each unit is supplied completely assembled, tested and sealed, ready for
installation. The electrical connection is made via 1, 2 or 3 cable assemblies with
FAA L-823 style 2-pole plugs. The 6 mounting screws (A1) and lock washers (A2)
or self locking nuts for holding the light on the base or adapter ring are included.
They can be either M10 or 3/8” UNC, according to order. An o-ring gasket (E6) is
also included.
Each unit is individually packed in a durable, cushioned and corrugated cardboard
box, labelled with Siemens Airfield Solutions and ordering numbers.
At least one instruction manual is delivered per order.

Film disc cutout

For some applications, optional film disc cut-outs are available. They form an
electrical bypass over the lamp within 15 seconds after lamp failure. After a lamp
failure, the film disc cut-out must be replaced.

References

Ordering codes and reference data pertinent to the light fixture and its components
are listed in the tables on pages 30 to 44.

Differences
between
versions

All the inset lights used for a particular function look externally identical. The
differences between versions depend on the beam colour and the optical support
inside. Make sure to use the correct version when installing the light onto its base.

Beam color

The colors of the light beams are identified by colored points on the top of the
window. A red point, for example, refers to a corresponding red colored beam.

In the 12” F-Range inset lights, light beam coloration is obtained by a dichroïc
coating applied on the inner face of the prism. Therefore, no separate color filters
are required.

Maintenance

Workshop maintenance and preventive maintenance

In the field
maintenance

The light assemblies can be serviced in the field, but it is recommended to limit field
maintenance to cleaning the prisms. It is recommended to replace the inset lights
at regular intervals and to have them overhauled in the maintenance shop. The
same applies to lights found unserviceable in the field.
Siemens Airfield Solutions designed a set of workshop jigs for dismantling and reassembling the fittings.

Preventive
maintenance

The assembly's service life depends to a large extent on its waterproofness. All
metal mating surfaces and seals must be clean, smooth, dry and free of all foreign
particles if the light fixture is to operate for extended periods without requiring
maintenance.
Greasing of O-ring seals may be required as indicated in this manual.
Preventive maintenance of the light fixtures should be performed as listed in the
table on the next page.
Maintenance frequency depends on the conditions under which the runway is used
(i.e. climate, traffic, etc.). The recommended practices for maintenance are
described in the FAA advisory circular AC 150/5340-26.
For components mentioned in this chapter, refer to the exploded view on page 44.

1. Pump water from base.

2. Clean, dry and inspect.
3. Replace O-ring and other parts found defective.

2. Remove, dismantle and inspect light for water
damage.
3. Cure the cause of water ingress.

After 800 hours
of operation at
6.6 A

Replace lamps of complete
subsystems (e.g. R/W
centreline)

It is recommended to replace the lamps
systematically when 80 % of the useful life has
been reached. At full brightness (6.6 A), it
represents 800 hours, but, in practice, life spans of
2000 to 4000 hours can be expected.

After snow
removal

for damaged light fixtures

1. Replace badly damaged fixtures.
2. Use a power broom for snow removal in the
vicinity of the light fixture, if practical.
3. Follow recommended snow removal techniques
described in FAA AC 150/5200-23 to avoid or at
least to reduce damage to light fixtures.

* More frequently during rainy seasons.

• Model a: simple tool used when the light fixture can be easily removed;
• Model b: a more sturdy tool to remove the light fixture in more difficult
conditions.

Procedure

To lift the optical unit out of the base receptacle or adapter ring, proceed as follows:
Step

Action

Remove the six fixing screws and washers (A1-A2) or self locking nuts.

Fit the appropriate lifting tool (see figure below) into both holes located
(180° apart) in the cover (B1), lift the optical unit out of the Eurobase or
adapter ring and place it next to it.

Disconnect the light fixture wires from the power wires coming from the
transformer(s).

Take the optical unit back to the maintenance base where it can be
serviced entirely.

Never hold the light fixture by the wires as this may damage the insulation, break
the waterproof seal and cause insulation faults and water leakage.

How to replace a lamp

Film disc
cut-out

When installed, always replace the film disc cut-out each time a lamp has to be
replaced.

Procedure

To replace a lamp, proceed as follows (for the tools to use, refer to page 43
“Screws Overview”):

Step

Action

Disconnect the fast-on connectors of the lamp from the terminal block (E1).

Remove the lamp (C ) from the lampholder (D3), holding the reflector.

If a cut-out is used, remove it by loosening the screw which secures the cut-out clip to the
terminal block (E1) and rotate cut-out clip free.

If a cut-out is used, position a new disc (small button side up) in the terminal block. Rotate
the cut-out clip on top of the cut-out and hold while tightening the screw. Make sure that the
pressure applied by the clip on the film disc is sufficient to assure good contact. If
loosened, remove the clip and bend it slightly to increase its pressure.

Install a new lamp.
To optimise photometric output, make sure that the lamp is correctly positioned with the
"arrow" pointing upside (up).

Never touch the quartz bulb of the lamp with your bare fingers. It will reduce the
lifetime of the lamp considerably. Should it happen, clean the bulb with isopropyl alcohol.
6

Reassemble in reverse order.
Make sure there is good contact between fast-on connectors and terminals.

Spare parts

It is recommended to create a sufficiently large stock of spare parts to maintain the
fittings. It will mainly consist of consumables like lamps, O-ring gaskets, film disc
cutouts, etc. Other components that may need replacement, such as prisms, prism
gaskets, terminal blocks and hardware even as sub-assemblies, should be
stocked in smaller quantities. The stock should also contain some complete fittings
of each type.
