Novak Brushed Speed Control: Eiger & Eiger Pro -- V1 (low profile heat sinks) (55-1835-1.2) - Manual

set-up guide proper gearing
Motor & ESC temperatures should NEVER exceed
160°F MAX at any time during operation !
If your application or vehicle set-up produces
excessive heating of either the speed control
or the motor, check for free operation of the
vehicle’s drive train and change the gearing if
needed to avoid overheating!
Because of the potential of damage from overheating that can cause ESC or
motor failure, you should start with small pinion sizes and check the
speed control and motor operating temperatures at during the initial runs
after installation. This is the best way to avoid excessive heating.
If ESC & motor temperatures remain low & stable, you can slowly increase
the pinion size while again monitoring the temperatures to determine the
safe gearing for your vehicle, motor, and climate/track conditions. Because
these variables can change or be modified, you should continually monitor
ESC & motor temperatures to protect your electronics from damage.
trouble-shooting guide
Steering Channel Works But Motor Will Not Run
• Possible receiver damage––Check operation with a different receiver.
• Possible internal damage––Refer to ‘SERVICE PROCEDURES’ section.
• Check motor or motor connections.
• Check ESC is plugged into receiver’s throttle channel. Check signal harness
wire sequence.
Receiver Glitches/Throttle Stutters During Acceleration
• Receiver or antenna too close to ESC, power wires, battery, or motor.
• Bad motor connections––Check wiring & connections.
• Low voltage to receiver––Try Novak Glitch Buster (#5626) on receiver to
retain power during surges of high current draw.
• PowerCap damaged/missing––Replace PowerCap/Trans-Cap Module.
• Battery pack damaged or weak––Try a different battery pack.
• Excessive current to motor—Use a milder motor or a smaller pinion gear.
• Untidy wires or signal and power wires are bundled together. Input harness,
servo harness, and power wires should be bundled separately. Power wires
should be as short as possible.
Motor and Steering Servo Do Not Work
• Check wires, receiver signal harness wiring & color sequence, radio system,
crystals, battery/motor connectors, & battery pack.
• Possible receiver damage––Check operation with a different receiver.
• Possible internal damage––Refer to Service Procedures.
Motor Runs Backward
• Reverse motor wiring––Swap RED & Black motor wire connections at motor.
• Improper One-Touch set up––Refer to ‘ONE-TOUCH PROGRAMMING’.
Speed Control Runs Excessively Hot
• Gear ratio too low––Increase gear ratio/Reduce pinion size.
• Motor is damaged––Try a different motor.
Model Runs Slowly/Slow Acceleration
• Gear ratio too high––Reduce gear ratio/Increase pinion.
• Bad battery or connectors––Check & replace if needed.
• Incorrect transmitter/ESC adjustment––Refer to ‘TRANSMITTER ADJUSTMENTS’.
• PowerCap damaged/missing––Replace PowerCap or Power Trans-Cap Module.
ESC Is Melted Or Burnt/ESC Runs With Switch Off
• Internal damage––Refer to Service Procedures.
No Power to the BEC
• Check power wire connections to your battery, ESC and BEC unit.
• Check that BEC input harness is plugged into receiver & the ESC’s red wire
is removed from the input harness.
• Be sure that the BEC unit switch is turned ON.
error/LED codes
• Red & Green status LEDs on solid––Check input signal harness connections.
Check input signal harness wiring sequence––Refer to STEP 3.
• Blue & Red status LEDs blinking. Possible thermal shut-down––Check gear
ratio & free operation of drive train for possible overloading/ESC is being
severely over-loaded––allow system to cool & return throttle to neutral to
regain motor control. LEDs will continue to blink until system is cooled down.
• Red & Yellow status LEDs toggling. LiPo battery has reached critical safety
voltage & LiPo Cut-Off circuitry has cut-off throttle output. Recharge battery.

This speed control features Novak’s Smart-Stop Auto-Detect Voltage Cut-Off
Circuitry built-in, and when used properly will allow you to safely use LiPo
batteries, without letting the cells drop below their critical safety voltage
during operation that results in premature battery failure.
The default ESC setting is that the Voltage Cut-Off is turned ON and is set to
LiPo. If using NiMH cells, you need to switch the Voltage Cut-Off feature OFF.
Yellow status LED will remain ON at all times during operation
to indicate that the LiPo Voltage Cut-Off Circuity is turned ON.
Re-charge battery after Smart-Stop circuitry shuts off throttle
Even though the pack’s voltage will rise (after a short resting period) to a level
high enough to run motor again, this is not good for LiPo batteries.
Reaching critical safety voltage too many times can damage the cells.
Note: Whenever the speed control’s One-Touch Programming is
performed, this setting will revert to the LiPo default setting.
DO NOT USE LiPo BATTERIES WITH THE
VOLTAGE CUT-OFF CIRCUITRY TURNED OFF
With the Voltage Cut-Off turned ON & using NiCd/NiMH cells, the
ESC’s throttle output will shut off very early into the run--Change the
Cut-Off Circuitry mode to OFF to use these batteries.
voltage cut-off circuitry
temperature monitoring
This speed control has a built-in diagnostic temperature monitoring feature
that lets you quickly and easily check the ESC’s operating temperature at any
time with a click of the ESC’s push-button.
While connected to a battery and powered ON,
simply tap the ESC’s SET
button and one of the on-board LED lights will flash 4 times to indicate the
operating temperature of the speed control:
BLUE flashing LED = normal operating temp-- 136-147°F (58-64°C).
YELLOW flashing LED = medium operating temp-- 148-167°F (65-75°C).
GREEN flashing LED = hot operating temp-- 168-194°F (76-90°C).
RED flashing LED = hottest operating temp--195-215°F (91-102°C).
You are now pushing the ESC extremely hard and should be very
careful to avoid overheating and possible thermal shut-down.
All LEDs flashing = DANGEROUS operating temp-- 216-239°F (103-115°C).
Your ESC is now about to thermally shut-down.
Reduce the pinion size/check drive train to avoid ESC
overheating that could result in potential damage.
