Important Safety Notes

You have acquired a Multi-Light module which can be installed as part of a fully working RC model.
However, we as manufacturers have no control over the way you build and operate your RC model
aircraft, nor how you install, operate and maintain the associated components, and for this reason
we are obliged to deny all liability for loss, damage or costs which are incurred due to the
incompetent or incorrect use and operation of our products, or which are connected with such
operation in any way. Unless otherwise prescribed by binding law, the obligation of the
GRAUPNER company to pay compensation, regardless of the legal argument employed, is
excluded. This includes personal injury, death, damage to buildings, damage due to loss of
business or turnover, interruption of business or other direct or indirect consequent damage whose
root cause was the operation of the model.

The total liability in all cases is limited to the amount of money which you actually paid for the
model.

The Multi-Light module is operated at the sole and express responsibility of the operator.
The only way to avoid injury to persons and damage to property is to handle and operate
the model with the greatest care and consideration at all times.

Before operating the Multi-Light module for the first time, please check whether your normal
household insurance policy covers the risks involved in operating RC models of this type. If you are
not sure, take out a special third party policy which specifically covers the operation of radio­controlled models.
These safety notes must be kept in a safe place. If you ever dispose of the model, be sure to pass
them on to the new owner.

The following points are important, and must be observed at all times:

• The Multi-Light module is not suitable for young persons under fourteen years of age.

• Before you operate your model, check that the radio control system is working reliably, and

that all plug-in connections are firmly seated.

• Ensure that the frequency you intend to use is not already in use by other modellers. Never
operate your model if you are not certain that your channel is free.

• Please remember that other radio equipment and transmitting stations can cause serious
interference to your model. Wherever possible, ensure that no apparatus of this type is
operating in the vicinity when you are running your model.

• Do not exceed the recommended operating voltage. Higher voltages may ruin the Multi-Light
module.

• Do not subject the Multi-Light module to high levels of humidity, heat, cold or dirt.

• Take particular care to waterproof your model. Open the model and allow it to dry out naturally

after every session.

Care and maintenance

• If water should get inside the model, open the access hatch and remove it immediately. If
water penetrates the case of the Multi-Light module, dry it out thoroughly before sending it to
your nearest GRAUPNER Service Centre for checking.

• We recommend that you apply WET.PROTECT, Order No. 968.50, to the module, as this
provides effective protection from damp.

Operating Instructions

Introduction

The Multi-Light module has been specially developed for RC modelling applications, and provides
a means of fitting out various types of model with a wide variety of lighting signals, such as
navigation lights, flashers, panoramic lamps and searchlights, as realistically as possible.
All the lighting functions are permanently installed in the module, and cannot be altered.
The functions are selected by moving the corresponding DIP switches and connecting the lamps to
the appropriate terminals.
We have carried out thorough research on the different lighting signals for vehicles, boats and
aircraft, and the signals are programmed in a logical arrangement in the module.
This Multi-Light module can be used for a very wide variety of model types.

Safety Notes

• Please read right through these operating instructions before using the module for the first
time, and store them in a safe place for possible future reference.

• The integrated circuits employed in the Multi-Light module are delicate, and vulnerable to
damage from electro-static charge. For this reason please avoid touching these components
unless you have first “discharged” yourself, e.g. by grasping a central-heating radiator or other
earthed device.

• The Multi-Light module may only be operated on the stated power supply voltages.

• All wiring and connections should only be carried out with the circuit disconnected from the

power source.

• The Multi-Light module is not suitable for use by young persons under fourteen years of age.

Modes of operation

There are three different modes of operation:

• Boat

• Ground vehicle

• Model aircraft

The mode of operation is selected by determining the model type using the DIP switches S1.1 ­S1.3.

“Boat” mode

In this mode of operation the lights are controlled using a Nautic switch module fitted to the
transmitter. The Nautic signal is connected to the Prop #1 input (X4/1). The red LED on the module
flashes to indicate that the Light module is picking up the Nautic signal correctly.

For model boats with a Voith-Schneider power system, the direction of travel can be detected via
the Prop #2 (X4/2) and Prop #3 (X4/3) inputs; in this case the lighting system is automatically
switched over when the boat is towing or assisting.

If a servo is switched on (Prop #5 and #6 output), this automatically moves to and fro between the
right and left end-points.

The frequency of the flickering light can be altered by adjusting the trimmer P1.
The speed of the servos can be altered by adjusting the trimmer P2.

“Vehicle” mode

In this mode of operation the lights are controlled using a Nautic switch module fitted to the
transmitter. The Nautic signal is connected to the Prop #1 (X4/1) input. The red LED on the module
flashes to indicate that the Light module is picking up the Nautic signal correctly.

The brake light and reversing light are switched via the Prop #2 (X4/2) input. This input is looped
between the receiver and the speed controller.
As an option, the steering channel can be looped through input #3 (X4/3). In this case the flashers
(direction indicators) are automatically switched off when the steering returns to centre after the
vehicle has completed a turning manoeuvre. If the steering channel is not connected, the flashers
continue to operate until they are switched off again using the Nautic switches.
The two servos (Prop #5 and #6 output) can be moved to right and left using the corresponding
switches on the Nautic switch module.
The frequency of the warning flasher can be altered by adjusting the trimmer P1.
The speed of the servos can be altered by adjusting the trimmer P2.

“Aircraft” mode

:

In this mode of operation the lights are controlled using a proportional channel (e.g. a slider) at the
transmitter. The proportional signal is connected to the Prop #2 (X4/2) input.
In this mode of operation the Light module’s power supply can be drawn directly from the servo
lead / receiver, i.e. it is not essential to connect a separate power supply to terminal X1. However,
in this case you must bear in mind that all the current drawn by the switched outputs flows through
the receiver. This means that the current drain of all the connected loads must not exceed 1.5 A. If
a higher current is required, you must connect a separate power supply to terminal X1.
Two servos can be connected to the Prop #5 and #6 outputs.
The servo at Prop #5 automatically runs to and fro between the right and left end-points
(searchlight).
The servo at Prop #6 can be used for a landing light. When the servo is activated, the servo runs to
the left end-point; otherwise it remains at the right end-point.
The frequency of the four-channel panoramic light and the running light (UFO only) can be altered
by adjusting the trimmer P1.
The speed of the servos can be altered by adjusting the trimmer P2.

Switched outputs

:

It is possible to connect LEDs, filament bulbs or similar to the sixteen switched outputs. The
voltage at the outputs is always the same as that of the power supply. It is therefore essential to
include dropping resistors in the LED / bulb circuits.
The value required for the resistors varies according to three different factors:

• The power supply voltage (U

• The voltage of the LED or filament bulb (U

)

B

)

L

• The current drawn by the LED or filament bulb (I)
The value of the resistor can then be calculated using the following formula:
U

- U

B

L

R = ---------­ I
Example

:
The power supply voltage is 7.2 V, and you wish to connect a white 3.5 V LED which draws a
current of 20 mA (= 0.020 A).

7.2 V

- 3.5 V

R = -------------- = 185 Ohm

0.020 A
However, since a resistor with a value of 185 Ohm does not exist, we take the nearest available
value, in this case 180 Ohm.
Finally the power rating of the resistor also needs to be calculated:
P = (U
P = (7.2 V

In this case a standard resistor with a power rating of 0.250 W (

- UL) x I

B

- 3.5 V) x 0.020 A = 0.074 W

1

/4 W) is adequate.

A separate dropping resistor should be used for each LED or filament bulb.
