Novak XXtra FM Synthesized Receiver - Manual (Page 2)

1. INSTALL MOTOR CAPACITORS
Electric motors generate radio noise that can cause
radio interference. Included are three 0.1
µ F (50V)
non-polarized, ceramic capacitors. These capacitors
must be installed on every motor to help reduce the
noise generated by the motor and also to prevent
possible damage to the speed control.
Solder 0.1
µ F (50V) capacitors between:
• POSITIVE (+) motor tab & NEGATIVE (-) motor tab.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (-) motor tab & GROUND tab*.
*If your motor does not have a ground tab, solder the capacitor leads to
the can of the motor as shown below.
Negative (-) motor tab
0.1 µ F Capacitors
Schottky diode
Positive(+) motor tab
Ground/Motor can
Extra 0.1 µ F capacitors are available in novak kit #5640.
2. INSTALL SCHOTTKY DIODE (if required)
Consult your speed control’s operation manual to
determine if an external Schottky diode is required.
Use of an external Schottky diode (even if your ESC
already has one in it) will increase the efficiency and
reduce the operating temperature of the ESC.
NEVER USE A SCHOTTKY WITH A REVERSIBLE ESC
• Solder the lead CLOSEST to the silver stripe on the
Schottky diode to the POSITIVE (+) motor tab.
• Solder the lead OPPOSITE the silver stripe on the
Schottky diode to the NEGATIVE (-) motor tab.
Schottky diodes are available in Novak kit #5640.
3. CONNECT STEERING SERVO
After the input harness wires on the steering servo have
been configured to match receiver (Refer to Step 2),
plug the steering servo into channel 1 on the XXtra.
4. CONNECT SPEED CONTROL OR THROTTLE SERVO
After the input harness wires on the ESC or throttle
servo have been configured to match receiver (Step 2),
plug the ESC or servo into channel 2 on the XXtra.
5. CONNECT AUXILIARY SERVOS
After the input harness wires on any auxiliary servos
have been configured to match receiver (Step 2), plug
the auxiliary servos into channels 3, 4, or 5 on the XXtra.
6. COVER OPEN SERVO RECEIVER CHANNELS
Use the included case slot plugs to cover remaining
channel openings. 2 and 3 channel plugs are included.
7. OPTIONAL USE OF EXTERNAL BATTERY PACK
A 4 or 5-cell receiver battery pack can be used if erratic
radio operation is experienced during hard acceleration.
Consult ESC manual for proper installation and usage.
The external battery pack’s plug inserts into the XXtra
with the positive (+) wire in the middle and the negative
(-) wire towards the outside/bottom edge of the case.
STEP 4
HOOK-UP INSTRUCTIONS
The XXtra receiver will work with all DSC cords. Insert the
input plug on DSC cord into the receiver’s BAT/DSC input
slot. Refer to the manufacturer’s operating instructions for
details on using the DSC cord feature.
If you do not have control of the servos when the DSC cord is
connected to the transmitter and the receiver, reverse wiring
sequence in the DSC cord input plug plastic and try again.
STEP 5
DSC CONNECTION
Servo And/Or Speed Control Does Not Work
• Make sure steering servo is plugged into channel 1 and
throttle servo or speed control is in channel 2.
• Check color sequence of input plugs––Refer to Step 2.
• ESC or electronics are not connected to battery pack.
• Check wiring and connections.
• Channel selector switches not on same frequency channel
as transmitter, or bad transmitter crystal––Refer to Step 1.
Receiver Glitches/Throttle Stutters On Acceleration
• Motor capacitors broken or missing––Refer to Step 4.
• Receiver or antenna too close to speed control, power
wires, battery, or motor––Relocate receiver/antenna.
• Bad connections––Check wiring and connections.
• Motor brushes worn––Replace brushes. Motor may also
be worn and need to be rebuilt.
• Excessive current going to motor––Use milder motor or
a smaller pinion gear.
• Bad transmitter crystal––Check system with another.
• Voltage to receiver is too low––Try using an external
receiver battery pack. Refer to Step 4.
• Possible internal damage––Refer to service procedures.
TROUBLE-SHOOTING GUIDE
FCC APPROVAL NOTE
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with
this instruction manual, may cause harmful interference to radio commu-
nications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try correcting the inter-
ference by one or more of the following measures: (1) Reorient or relocate
the receiver’s antenna; (2) Increase the separation between the equipment
and receiver; (3) Consult an experienced radio/TV technician for help.
