Novak ESC Cooling Fan (1930) - Manual

STEP 1
HEAT SINK INSTALLATION
Two Micro Fin™ heat sinks have been included to
provide proper cooling for the Elektra ESC. The
speed control will operate cooler and run faster
when the heat sinks are installed. DO NOT use the
Elektra without the heat sinks, this voids the warranty
and will cause the speed control to overheat and
thermally shut down.
1. INSTALL THE LEFT HEAT SINK
Place the speed control on a flat surface and press
one heat sink (longer fins go down onto transistor
tabs) onto the left bank of 2 transistor tabs.
NOTE: Do not use excessive force when installing
heat sinks because you can damage the transistors or
other components on the PC board. Never use a vise
or pliers to install the heat sinks.
2. INSTALL THE RIGHT HEAT SINK
Press the second heat sink (again, long fins down)
onto the right bank of 3 transistors tabs.
The heat sinks should press onto transistor tabs with
a snug fit. If heat sinks are installed upside-down or
shifted off-center, they will be too loose and will not
work properly.
3. DO NOT USE GLUE
Do not use glue or other types of adhesives to attach
the heat sinks to the transistor tabs.
4. DO NOT SHORT CIRCUIT HEAT SINKS
The two separate banks of transistor tabs or heat
sinks should never contact each other or other
conductive objects (metal, graphite, etc.), or they
will short circuit and damage the speed control.
STEP 2
MOUNTING INSTRUCTIONS
1. DETERMINE THE BEST ESC MOUNTING LOCATION
The speed control should be positioned away from the
receiver and antenna as shown in set-up photo on back
page. Choose a mounting position that will keep power
wires away from the receiver and antenna. Choose a
position that will provide maximum airflow through the
heat sinks to allow for proper cooling.
2. INSTALL THE SPEED CONTROL
Use the included double-sided tape to mount ESC.
3. INSTALL THE ON/OFF SWITCH
Determine a convenient place to mount switch where it
will be easy to get to. Mount switch using a piece of
double-sided tape. If your car has a switch mount
molded into the chassis, remove the two phillips head
screws from the switch housing and reassemble switch
into chassis using the 3/8" long screws included in the
speed control accessory kit. Note direction of ON/OFF
cover and reverse it if necessary.
4. INSTALL THE RECEIVER
Mount the receiver as far from the speed control, motor,
power wires, battery, and servo as possible. All these
components emit radio noise when the throttle is being
applied. If your car has a graphite or aluminum chassis,
place the receiver on edge with the crystal and antenna
as far above the chassis as possible. The receiver can
also be mounted on the shock tower.
5. INSTALL THE ANTENNA
Mount the antenna as close to the receiver as possible.
Trail any excess wire off the top of the antenna mast.
Do not cut or coil excess wire.
Cutting or coiling excess wire will reduce radio range.

OPERA
TING INSTRUCTIONS
The Elektra is an entry-level mid-frequency speed control created with the high-end racing technology that Novak Electronics is known for. The Elektra features the original
One-Touch Set-Up™
for quick and easy
set-up.
With Novak's revolutionary
Polar Drive Technology™
and
Digital
Anti-Glitch Circuitry
TM
the Elektra runs longer and smoother than
conventional ESCs (Electronic Speed Controls). While
Radio Priority
Circuitry
TM
maintains total steering control even after the main battery
pack has discharged and can no longer move the vehicle. The Elektra has a built-in Schottky diode and BEC (Battery Eliminator Circuit), to
provide radio system power without an external receiver battery.
The Elektra also has
Thermal Overload Protection
and purple anodized
Micro Fin™ heat sinks to ensure smooth and cool operation. The factory- installed JST/Tamiya style battery connectors and bullet motor connectors make for quick and easy installation of the speed control into your car or truck.
All Novak ESCs are guaranteed to be free from defects in materials and workmanship for
a period of 120 days from the original date of purchase. Complete warranty details inside.
ELEKTRA ACCESSORIES
MOTOR CAPACITORS
To prevent radio interference problems, you must have
three 0.1
µ F capacitors properly installed on every motor.
Included with the Elektra speed control are three 0.1 µ F
(50V) capacitors (enough for one motor). Additional 0.1 µ F
(50V) capacitors are available as Novak Accessory Kit
#5620 which contains 25 capacitors. Please refer to
Step 4 on the back page for proper motor capacitor
installation instructions.
HEAT SINKS
A replacement heat sink set is available for the Elektra
speed control in Novak Accessory Kit #5408. These
purple anodized Micro-Fin heat sinks provide the
proper transistor cooling that is required to get the
best performance from your speed control. The heat
sinks keep the operating temperatures low to prevent
overheating and thermal shut down, and result in more
efficient speed control operation.
PRECAUTIONS
• READ INSTRUCTIONS CAREFULLY BEFORE USING!
• WATER & ELECTRONICS DON'T MIX! Do not operate
model in or around water. Never allow water, moisture, or
other foreign materials to get inside the ESC.
• 6 CELLS ONLY Never use more or fewer than 6 sub-C cells
(1.2 volt DC/cell) in the main battery pack.
• MOTOR CAPACITORS REQUIRED Three 0.1 µ F (50V)
ceramic capacitors must be properly installed on every
motor to prevent radio interference.
• DO NOT REMOVE BATTERY OR MOTOR CONNECTORS
Internal damage can occur and will void the warranty.
• DON'T LET TRANSISTOR TABS TOUCH Never allow the
two transistor tab banks or the heat sinks to touch each
other or any exposed metal, as this will create a short circuit
and damage the speed control.
• DISCONNECT THE BATTERIES Always disconnect the
battery pack from the speed control when not in use.
• TRANSMITTER ON FIRST Always turn on the power of
your transmitter first so that you will have control of the
radio equipment when you turn on the speed control.
• DON'T GET BURNT! Transistor tabs can get hot, so be
careful not to touch them until they cool.
• INSULATE WIRES Always insulate exposed wiring with
heat shrink tubing to prevent short circuits.
RADIO INTERFERENCE
The high frequency switching operation of electronic
speed controls can generate radio interference. Here are
some common causes of radio interference problems:
• CAPACITORS NOT INSTALLED ON MOTOR Electric
motors generate radio noise that can interfere with the
receiver. To prevent radio problems, every motor must
have three 0.1
µ F (50V) ceramic capacitors installed on
it. Refer to Step 3 on back page for proper installation.
• RECEIVER/ANTENNA INCORRECTLY MOUNTED The
receiver and antenna should be mounted as far from
the motor, power wires, battery, and servo as possible,
as these components all emit radio noise. On graphite
or aluminum, place receiver on edge with the crystal
and antenna as far above the chassis as possible. Mount
the antenna close to receiver and trail any excess wire
off the top of antenna. Do not cut or coil excess wire!
• MOTOR BRUSHES WORN As motor brushes continue
to wear, excessive motor noise will be generated. To
avoid radio interference, worn motor brushes should
be replaced. The motor commutator may also need to
be cleaned or trued and can be machined to help the
motor run more efficiently.
