Connection of the drive motor
As drive a DC brush motor with a nominal voltage of 7.2V is required. Brushless motors cannot be used with the
ElMod 3to
.
The motor maximum current consumption is limited to 20A peak. The allowed permanent load is 10A. The
motor driver is protected against short circuit and overload.
•
Solder the yellow and black motor line to the motor
•
If necessary, use the provided shrink tube to isolate the endings to prevent short circuits.
•
Keep the cable length as short as possible in order to prevent interferences! For additional interference
protection the motor cables can be twisted.
•
IMPORTANT! The motor must be interference-suppressed. This is accomplished with the use of three
capacitors as shown in the figure. Many motors are already equipped with proper interference-suppression.
Please check for this condition by asking the producer or distributor.
For checking the correct wiring of the motor proceed as follows:
•
Make sure that the driving shaft is free to move and the vehicle cannot start uncontrolledly
•
Connect the fully charged battery with the electronics and connect the power supply in accordance with the section „connection of power
supply“
•
Please wait for 3 - 4 sec, then press and hold the push button S1.
•
The motor starts rotating. If the driving shaft rotates forward, the motor is connected correctly. If the driving shaft rotates backwards, the
motor wiring must be swapped.
Lighting
The
ElMod 3to
is able to control three lighting channels (see image)
•
connector 1 frontlight
•
connector 2 for combined rear lights with brakelight
•
connector 3 for camo light
For each light one or two LEDs in any color and type may be connected. The light connections are short
circuit protected and limits the current at 30 – 40 mA. The brightness of each light channel can be
individually adjusted by the
ElMod App
.
•
Front lighting: the LEDs are connected with light channel 1 by one of the provided cable. By using two
LEDs they must be connected in parallel as shown on the image.
•
Combined rear lights with brakelight: the LEDs are connected with light channel 2 by one of the
provided cable. By using two red LEDs they must be connected in parallel.
•
Camo light: the LED is connected with light channel three by on of the provided cable.
The LEDs are protected against wrong polarity. If the LED is wrong connected it won't light up but it
cannot be damaged. To light up the LED, the anode must be connected with the red cable/wire/line and
the cathode with the black cable/wire/line (see image). If you use wired LEDs you can recognize the
cathode by the shorter wire, the larger electrode or the flattening of the body. If you use SMD-LEDs you
can recognize the cathode by a little dot/spot inside or on the bottom side of the LED.
Installation and Connection (sound unit)
•
Connect the provided volume control with the connector 7.
•
Connect the loudspeaker's cable with the output of a suitable 8 Ohm loudspeaker with a power of at
least 1 W to the connector 7. The loudspeaker's polarity (+/-) makes no difference at this. We
recommend the Visaton
®
BF32 which may be installed in a small box between the servo and the
radiator.
For checking the correct function of the sound unit proceed as follows:
•
Disconnect all connections to the
ElMod 3to
except the battery, the volume control and the
loudspeaker.
•
Ensure that a microSD card with suitable contents is inserted
•
Switch on the voltage and wait until the status LED of the sound unit (L2) lights up permanently.
Should this not work within max. 10 sec. see section „status LED“ for advice.
•
Press and hold the test button for sound unit S2. A sound is played and the status LED L2 starts flickering. After repressing the S2 key
