1 General information

The layout of this manual

This manual includes technical information about the Hella Induperm range of Runway Guard Light

fixtures.

The range of RGL fixtures are constructed and manufactured of standard parts mostly produced in-

house. A large part of the mechanical construction, the LED modules as well as the electronic are

used in a number of Hella and Hella Induperm light fixtures. This reduces the necessary amount of

spares in an airport.

1.1 The use of the manual

The manual is intended to be used for installation, operation, maintenance of the RGL, as well as for

purchase of spare parts.

1.2 Manufacturer information

2 Overall RGL 921 information

2.1 Relevant standards

The range of RGL 921 High Intensity is constructed, manufactured and tested to meet the

requirements in ICAO annex 14, 5.3.20 for use in configuration A as elevated marking of

Runway/Taxiway intersections. Maximum Average intensity of 3000cd with light distribution

according to ISO candela diagram fig. 2.25 with less than 40W /Light output.

Lightweight construction with no heavy parts above ground level.

2.2 Main data

The RGL 921 light fixtures uses the same technology and main parts as used in unidirectional LED

light fixture type 792 for Approach, Side row, Threshold and End Light.

The RGL 921 light fixtures have a built flasher electronics which automatically synchronizes when

switched on.

Designed to meet all environmental conditions given in FAA AC No. 150/5345-46D for L-804.

Standard height app. 480mm

Standard 100% input current is 6,6A, and the fixtures can be dimmed to 2,8A.

Features:

The outside of the yellow front glasses is smooth and needs no cleaning

Extremely easy levelling and adjustment due to patented ball joint.

No adjustment after change of LED module or electronics.

Only fully, corrosion proof components are used.

Finished in stove enamel aviation yellow, RAL 1028

The high intensity RGL 921 are always supplied with a visor for protection of LED from sunlight

and to maximize contrast between lamp-on and lamp-off states

Two types of breakable couplings available:

Type A for 2” thread

Type C for Ø-2” (60mm) pole mounting

45 flashes per minute per lamp

Shipping details per fixture: 10Kg / 0,1 m3

2.3 RGL 921variants

a. Input

RGL 921 is as mentioned before constructed for nominal 6,6A series circuits, but a special

transformer can be supplied, if a parallel supply (120 or 230VAC) is required.

b. Fail Open relay

The RGL 921 can be supplied with or without a Fail Open relay. The Fail Open relay can be

programmed for customer specified functions.

Each side of the RGL fixture is controlled and monitored individually by the electronics. If a failure

is detected, this will activate the fail-open relay. If the RGL unit is with only one input cable, the Fail

Open relay will switch-off the complete unit and report the error to the system outside by opening the

power supply line. For RGL fixtures with two input cables, two nos. Fail Open relays can be built-in,

and in this case a detected failure will only switch-off the faulty lamp and leave the other side on.

c. Height of fixture.

The RGL 921 light fixture can upon request be quoted in customer specified heights.

2.4 Warranty limitations

The manufacturer or his representative cannot be held responsible for failures and malfunctions, if

the instructions in this manual are not followed.

The RGL 921will meet all specifications when installed and operated as specified.

Hella Induperm A/S only has responsibility to replace faulty parts if construction, production or

component failure is proven.

3 RGL 921 DESCRIPTION

3.1 General Information

Hella Induperm RGL 921 light fixtures are constructed mainly by using standard components from

Hella-Induperm standard program of elevated fittings. Each fitting has two light systems. Each light

system is a unidirectional, yellow light. Each light system can be individual adjusted for toe-in and

elevation.

The fitting has a breakable coupling, designed for 2” (60mm) stake mounting (Type C) or with 2”

thread stub (Type A).

The light fixture is designed for an expected lifetime for the LED´s of 50.000 Hours.

3.2 RGL electronics

The driver electronic for the LED modules are identical to the electronics used in Hella inset lights

and in Hella Induperm elevated unidirectional lights for Approach, Siderow, Threshold, Threshold

Wing bar and for Runway End light.

The electronic will transfer the RMS value of the 6,6A series circuit current into the necessary LED

current. The electronic is informed about the LED current needed from the EPROM memory on the

LED module.

The electronics also have a built-in facility for flashing the LED’s and to automatically synchronize

to the Ac input when switched-on. One of the two light units are programmed to start off and the

other to start on, and the two lights stays synchronized by means of the counting the half waves on

the power supply. The RGL units can be ordered with or without activated internal flasher.

3.3 Light output performance

Three parameters are essential for the correct light output.

The color of the LED output together with the yellow front glass defines the correct color.

The LED light output together with the lens on each LED defines the correct light distribution.

4 RGL installation

4.1 Unpacking the RGL fixtures

The RGL units are supplied in individual boxes.

Please make sure that nothing is broken before starting installation.

As standard, the RGL light fixtures are not pre-adjusted in the factory and must be adjusted before

taken into operation.

4.2 Theoretical installation consideration

As standard, the two light fixtures on the same pylon are adjusted identical, that is with parallel light

output. On complicated intersections with f. i. more taxiways, other ways of adjustment might be

used.

Vertical adjustment:

With a main Beam coverage of ± 4°, the Main beam coverage will be down to 0 ° with a vertical

adjustment to 4°. With this adjustment, the Main Beam will cover from ground level and 14 m up in

a distance of 100m. This might be too little, and we suggest a coverage form 1,2m above ground

(corresponding to a person sitting in a vehicle) in a distance of 50 m, corresponding to a beam

elevation of 5,2°, which again will give a Main beam coverage from 2,4 m above ground and up to

16,2 m in a distance of 100 m.

Toe-in:

If we aim the light direction to a point in the middle of the taxiway in a distance of 100 m, this will

correspond to a Toe-in of 12°, and give a Main Beam coverage 160 m out and to a point 70 m from

the RGL line.

Conclusion:

We recommend to adjust the light fixtures with a vertical elevation of 5,2°, and a Toe-in of 12°.

4.3 Before the installation

To simplify installation the light fixtures can be pre-adjusted in the workshop, as follows:

The two light units are adjusted to have parallel light output perpendicular to the pylon, and with a

vertical setting of 5,2°.

4.4 Installation in the field

The pre-adjusted light fixture is electrical connected and mounted in the breakable coupling without

tightening the screws in the breakable coupling. The pylon is turned until it is perpenticulat to a line

towards a point in the middle of the taxiway, 100 m away from the RGL line. The screws in the

breakable coupling are tightened.

5 Maintenance

5.1 In the field

Every 6 month:

The elevation and Toe-in adjustments are controlled

How to mount the adjustment tool:

Regularly:

Front glass is cleaned if necessary, and a visual control of similar light output from both light units.
