Led Light Assemblies - 71110( ) Series - Whelen Engineering Company OR5001V Installation And Service Manual

71110 ( ) SERIES WING TIP LED FORWARD
POSITION LIGHT STROBE ASSEMBLY
71110 series is a wing tip mounted strobe anti-collision/position light
assembly utilizing LED's for the forward position lights. The LED's pro-
vide a significant reduction in current draw over conventional position
light bulbs. The strobe light lens assembly is radio shielded for maximum
EMI/RFI protection. Direct replacement (exact footprint) for the Whelen
Model A650PG/PR series without replacing the current strobe power
supply. Navigation light portion is wired with flying leads.

Operation
EQUIPMENT LIMITATIONS: An approved lighting system consists of
two lights, one located on each wingtip. The baseplate must be
mounted parallel to the vertical and horizontal centerlines of the air-
craft to project the patterns properly. The strobe tube assembly must
be connected to a strobe power supply, such as Whelen model
70888, 70879 or other approved models.
CONTINUED AIRWORTHINESS: The 71110 series LED wingtip posi-
tion light assembly is designed with 3 LED's. If any one LED fails, the
unit must be repaired or replaced.
Inspect the lens. Replace if there is excessive scratching, discolor-
ation or cracking.
INSTALLATION PROCEDURES: The following information is to assist
in the installation of a Whelen 71110 LED Forward Position Light/
Strobe System.
1. Choose appropriate 71110( ) series replacement light assembly.
2. The installation procedure described in the following text will be
confined to a single light installation, but is identical for multiple
light installations.
3. Remove the old light, locate and save the existing +VDC lead and
(-) ground lead. Clean and prep ends as required.
4. Make sure the existing system is equipped with an appropriate
sized breaker. Connect the existing +14/ 28 VDC lead to the
POSITIVE wire on the input cable assembly (supplied with the
light assembly). Connect the existing ground lead to the GROUND
wire on the input cable assembly or use the supplied connector
as shown in the illustrations. Both leads must be connected by
an approved FAA connection. Insure that the wire leads are clear
of any obstructions and ty-wrap as required. Connect the strobe,
J1, to the strobe power supply as shown in the figure.
5. Remove the shroud from the light assembly.
6. Position the base of the new light assembly onto the mounting
surface. Insert three (3) #6-32 pan head screws into the mount-
ing hole and tighten firmly.
7. Reinstall the lens so that the two notches are positioned under
the shroud, with each notch equadistant to the centerline.
8. Check all avionics systems for interference from the installation.
