CONTINUED AIRWORTHINESS:

The Pulsar NS series LED navigation and anticollision

light assembly is designed with 4 forward navigation LEDs, 2

rear position LEDs, and 18 LEDs mounted beneath the anti-

collision lens. Should any one LED fail, the unit must be

repaired or replaced. View LEDs with welding goggles for

eye safety.

INSTALLATION PROCEDURES:

1. The installation procedure described in the following text is for a

single light installation, but the procedure is identical for multiple

light installations.

2. Print out the installation template (the page 3 of this document),

however be sure to set up the printer driver to NOT use Page

Scaling so the printer will replicate the template to the proper 1:1

scale, otherwise the template will be too small. The proper scaling

can be verified by placing the included ‘Y’ Mounting Bracket over

the printout to ensure a 1:1 fit.

3. By design, the ‘Y’ Mounting Bracket locks into the NS product

body.

4. Print the template as described above and confirm a 1:1 scaling of

the printout.

5. Attach the template to the wingtip (mounting) position and mark

the screw and wire hole locations.

6. Mount the bracket using three 6-32 100 degree countersunk

screws. Ensure that the mounting bracket is grounded to

structure via the mounting screws. If necessary, route a ground

strap from one mounting screw to structure ground or terminate

the ground shield from the shielded wire bundle to a mounting

screw. Proper chassis ground is required for minimum RFI and for

protection from direct lighting effects.

7. Connect the red wire to switched power for the position lights,

connect the yellow wire to switched power for the strobe lights,

connect the black wire to the structure ground used to ground

the mount, and connect the green wire to the synchronization

wire from the other installed light(s). It is recommended that the

attached wiring diagram be followed for minimum RFI.

8. Attach the light to the mounting bracket and anchor in place with

the 8-32 hex head set screw (provided) that inserts into the rear

of the light.

9. Check all avionics systems for interference from this installation.

10. A flight check should be performed by a properly certified pilot.

The AeroLEDs Pulsar NS series is a combined LED navigation and anti-collision light assembly designed for aircraft. This device serves two primary functions: providing position (navigation) lighting and strobe (anti-collision) lighting, both essential for aircraft visibility and safety.

Function Description:

The Pulsar NS series integrates both navigation and anti-collision lighting into a single compact unit. For navigation, it utilizes four forward-facing LEDs and two rear-facing LEDs to provide the necessary position lights. For anti-collision, it incorporates eighteen LEDs mounted beneath a dedicated anti-collision lens, designed to produce a bright, attention-grabbing strobe effect. The system is designed to operate on both 14-volt and 28-volt aircraft electrical systems, offering versatility across a range of aircraft types.

Important Technical Specifications:

Operational Voltage: The device is compatible with both 14-volt and 28-volt electrical systems.
Position Light Current Draw:
- At 14V: 0.4 Amperes
- At 28V: 0.2 Amperes
Strobe Light Average Current Draw:
- At 14V: 0.8 Amperes
- At 28V: 0.4 Amperes
Strobe Light Peak Current Draw: 2.25 Amperes at 14V for 0.33 seconds. This high peak current ensures a powerful flash for visibility.
Light Output:
- Position Lights: Exceeds 100 candela.
- Strobe Lights: Exceeds 400 effective candela. These values indicate significant brightness for both functions, meeting or exceeding aviation safety standards.
Wiring: The system uses a three-conductor 20-gauge shielded cable for connection. Specific wire colors are designated for different functions:
- Red Wire: Switched power for position lights.
- Yellow Wire: Switched power for strobe lights.
- Black Wire: Structure ground.
- Green Wire: Synchronization wire (for multiple light installations).
- The manual specifies 22 AWG for red, yellow, and black wires (M22759/16-22) and 24 AWG for the green wire (M22759/16-24), all with a length of 6.0 inches.
Mounting: The light assembly is secured using a 'Y' Mounting Bracket (part number 01-1082) which locks into the NS product body. The bracket is attached to the aircraft structure with three 6-32 100-degree countersunk screws. The light itself is then anchored to the bracket with an 8-32 hex head set screw.
Grounding: Proper chassis ground is critical for optimal performance, minimizing Radio Frequency Interference (RFI), and providing protection against direct lightning effects. The mounting bracket must be grounded to the aircraft structure, and a ground strap or the shielded wire bundle's ground shield should be connected to a mounting screw if necessary. The black wire from the light also connects to the structure ground.

Usage Features:

Dual Functionality: Combines navigation and anti-collision lights into a single unit, simplifying installation and potentially reducing drag compared to separate components.
Wide Voltage Compatibility: Operates on common aircraft electrical systems (14V and 28V), making it suitable for a broad range of aircraft.
Synchronization Capability: The green synchronization wire allows multiple Pulsar NS units (or other compatible strobe lights) to flash in unison, enhancing visibility and creating a more cohesive lighting pattern.
Robust Design: The use of LEDs provides inherent durability and a longer lifespan compared to traditional incandescent bulbs.
RFI Minimization: The design emphasizes proper grounding and shielded cabling to minimize RFI, which is crucial for preventing interference with other aircraft avionics.
Ease of Installation: The manual provides a detailed, step-by-step installation procedure, including a 1:1 scale template for accurate drilling and mounting. The 'Y' Mounting Bracket is designed for a secure and straightforward attachment.

Maintenance Features:

LED-Based System: LEDs are known for their long operational life, significantly reducing the frequency of replacement compared to older lighting technologies.
Fault Indication: The system is designed such that if any single LED fails (either in the navigation or anti-collision section), the entire unit must be repaired or replaced. This ensures that the light output remains compliant with safety standards.
Visual Inspection: Regular visual inspection of the light assembly is implied, especially given the "Continued Airworthiness" section.
Specialized Viewing: When inspecting the LEDs, particularly the anti-collision strobes, the use of welding goggles is recommended for eye safety due to the intensity of the light.
Professional Repair/Replacement: The manual states that if an LED fails, the unit "must be repaired or replaced," suggesting that maintenance beyond simple cleaning or external inspection should be performed by qualified personnel or involve replacing the entire assembly.
Post-Installation Checks: After installation, it is mandatory to check all avionics systems for interference and to perform a flight check by a properly certified pilot. This ensures that the new installation does not negatively impact other aircraft systems and functions correctly in an operational environment.
