                         NLD8110-03 Dual-Marslight Simulator Effect and Installation

Description of Lighting Effects

This NLD8110-03 provides a tiny, low-voltage/low-current circuit which produces a dual Marslight simulation that runs for two 20ma  white family (white, incandescent, yellow-white, golden-white) LEDs in simultaneous operation. 

            

                    All solder connections explained below

                                   Figure 1

NLD8110-03 (DCC/RC) input power connections:

The NLD8110-03 Simulator is configured for DCC environments and sound decoders having 3.3-volt accessory functions. Since track polarity is not a factor in DCC the need for DC polarity protection is not required. Also, in an RC modeling environment, battery power is known so this is not an issue. However, since this family of Simulators doesn't have polarity protection, care must be taken during wiring to ensure polarity is correct before power is applied. Otherwise, the circuitry will be damaged. Figure 1 above shows a detailed view of the locations of the wires to be attached as viewed from the front side of the circuit board. These wire are included in this package.

Utilizing the one of the industry’s most advanced microcontrollers and highly regulated voltage control circuitry, this total module consumes less than 40ma of current during normal operation with all LEDs attached. Input DC voltage range is 3.4 to 20 volts.

Preparing the NLD8110-03:

The module’s tiny size and thin construction will allow it to be placed so it is easily hidden from view. The module has circuitry both sides so care must be taken when mounting to prevent  contact with metal (electrically conductive) material which could cause a short circuit. The bottom of the circuit board can be used for mounting with the small square double-sided sticky foam pad that is included.

Important note: A low-wattage iron (15-watt or less) should be used for this process and a needle type pointed tip should be used for connection of the wires to the module. Too much heat or solder can  damage the wires, LEDs & module and void  warranty.

Figure 1 above shows a detailed view of the locations of the wires to be attached as viewed from the front side of the circuit board. These wire are included in this package.

Soldering wires to the module:

Each of the six wires should be stripped and tinned prior to attachment to the circuit module. Strip approximately 1/4” of insulation from each end of each wire, ensure the wire strands are twisted together and carefully tin each end.

Each wire’s tinned end should be inserted into the appropriate solder point as shown above, with the wire inserted from the front side of the board and soldered on the back side of the board. For this process, good lighting, magnification, and a method to hold the circuit while soldering with be very helpful in proper positioning of the wires.

Extra care must be taken when soldering these wires in position. Because of their close proximity, excess solder can easily cause bridging between pads.

Soldering wires to the module—continued:

For best success in soldering the wires, place each wire into the appropriate solder hole and seat the insulation up against the hole on the front side of the board. Ensure the wire is held in that position when applying  any flux and solder to the hole on the back side of the board.  It is easiest if a small amount of solder is placed on the soldering iron tip first, then the wire is placed in position and flux is applied  at the back side of the hole. While holding the wire in position, touch the tinned wire strand and the hole with the soldering iron tip allowing the solder to flow into the hole capturing the wire. This soldering process should only take about 1/3 of a second to provide a clean shiny solder joint with no excessive solder. Then, carefully snip the protruding wire from the solder joint. This will ensure a good joint and eliminate possible shorting. Repeat this process for all remaining wires.

 

Again, a low-wattage iron (15-watt or less) should be used for this process and a needle type pointed tip should be used for connection of the LEDs to the wires.

...A shameless promotion...

Should you not have the soldering tools necessary to perform the previous steps, our 12-watt N40M2 soldering iron with the N408I tip is perfect for these operation and we also have N4200 low-temperature 2% silver solder and N4500 no-clean liquid soldering flux for easy soldering...

Testing and mounting the assembly:

At this point, the NLD8110-03 Simulator assembly is completed and should be tested prior to installation. Figure 2 below shows  red and black wires soldered on the right side of the circuit (rear view). These two wires are for power input and should be connected to your power source.

REMINDER: This module DOES NOT HAVE reverse polarity power protection, so be extra careful when connecting the +DC RED wire and the –DC BLACK wire to your power source. Connecting the backwards will damage the module.

Once power has been applied and all LEDs appear to be function normally, the assembly can be mounted into your project.  Included in this package is a small double-sided sticky foam pad. Peel one of the protective backings off of the pad and stick it to the bottom side of the module. The foam will help electrically insulate the module from contact with any metal parts.

LED symbols shown indicate “A” (anode +DC) & “C” (cathode –DC) connections.

This completes connection of the NLD8110-03 module. It is recommended that a thorough re-inspection of all connections and module placement be performed prior to applying power to your model. We hope you enjoy the added realism our module provides.
