functionality is patent pending and the sole property of Novak R/C, Inc.

The included cooling fan is recommended for 3-cell operation.

The M2 Dig ESC features a set of power output pins for running cooling fans,

auxiliary lights, scale winches, etc. This power is regulated to 6.0VDC

(same as the

BEC)

, and switches on & off with the ESC’s power switch, so you get maximum

output without over powering by running directly from the battery pack’s voltage.
The M2 Dig’s heat sink is designed to accept a 25x25mm cooling fan, and comes

with nylon 4-40x5/8” screws to secure it. To install, simply center fan on ESC

and push the nylon screws down into the cross cuts of heat sink. If using metal

screws

(M3 or 4-40)

, thread them into the heat sink.

The pin-out label located on the ESC’s

case under the pins & LEDs shows the

polarity of the power output pins,

which are the two pins on the corner

of the ESC. Positive (+) is on the left,

and Negative (–) is on the right.
The two sets of three pins behind the

power output pins are for the input

signal harnesses. The polarity is the same

for both: Positive in the middle, Negative

on the left, and signal on the right.

CONTACT:

The M2 Dig has a built-in Novak Smart-Stop Voltage Cut-Off Circuitry to safely use

2S or 3S LiPo or LiFe battery packs by cutting off the speed control’s throttle output

when the critical safety voltages are reached. The default is for LiPo batteries.

When the ESC is switched ON, the Yellow & Red LEDs will flash together 2

times. To change to LiFe or OFF, download the M2 Dig Field Guide on the

Novak website (www.teamnovak.com/downloads).
The circuitry constantly monitors the pack voltage and automatically selects a 2S

or 3S cut-off voltage value

[6.25V (2S), 9.75V (3S) Li-Po; 4.75V (2S), 7.125V (3S) Li-Fe]

. When

the ESC detects that the critical safety voltage will soon be reached, it begins

“blipping,” the throttle output. When the critical voltage is reached, the throttle

output to the motor gets completely shut down to keep the voltage from dropping

further (Red & Green LEDs will alternately flash & you still have steering control).

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 or LiFe batteries.

Reaching critical safety voltage too many times can damage the cells.

DO NOT CONTINUE TO RUN VEHICLE AFTER THE SMART-STOP HAS SHUT

DOWN THE THROTTLE OUTPUT THE FIRST TIME.

Note: With the Voltage Cut-Off Circuitry turned ON & using NiCd or NiMH cells, the circuitry will

shut off the ESC’s throttle output very early into the run, due to the different characteristics of

these batteries. Change the ESC’s Voltage Cut-Off Circuitry mode to OFF to use these batteries.

Before perfoming One-Touch Set-Up, be sure ESC is connected to (at least) a receiver

and a charged battery pack. It is best to remove at least one wire from each motor.

The transmitter’s Aux/3rd channel

(3Ch required for Dig) set to its middle position:

For single motor operation, the ESC’s throttle profile must be changed to #3

BEFORE doing One-Touch Set-Up- refer to M2 Field Guide on Novak website.

1. TURN ON THE TRANSMITTER’S POWER

2. PRESS & HOLD ESC’S ONE-TOUCH/SET BUTTON
3. TURN ON THE SPEED CONTROL’S POWER

With transmitter throttle at neutral, and still pressing the SET button, slide the

ESC’s ON/OFF switch

to ON position.

4. CONTINUE HOLDING SET BUTTON UNTIL RED LED COMES ON

5. RELEASE SET BUTTON AS SOON AS LED TURNS RED
6. PULL TRANSMITTER THROTTLE TO FULL-ON POSITION

Hold it there until the green status LED

turns solid green. (Note: Motor will not run)

7. PUSH TRANSMITTER THROTTLE TO FULL-BRAKE/REVERSE

Hold it there until the green status LED

blinks green.

8. RETURN TRANSMITTER THROTTLE TO NEUTRAL

The blue & red status LEDs will

turn on solid, indicating that speed control is now

ready to program the Aux/3rd channel that is used for the Dig feature.

(Note: If

using the Single Output Mode without Dig, ESC will exit programming here)

9. CHANGE TRANSMITTER’S AUX/3rd CHANNEL TO ONE END POINT

The blue & green status LEDs will

turn on solid.

10. CHANGE TRANSMITTER’S AUX/3rd CHANNEL TO OTHER END POINT

The blue status LED will

turn on solid & the green LED will blink.

11. RETURN TRANSMITTER’S AUX/3rd CHANNEL TO NEUTRAL

The blue, yellow, & red status LEDs will

turn on solid, indicating that speed

control is at neutral and that proper programming has been completed.

NOTE: If transmitter settings are changed, One-Touch Set-Up must be repeated. If you

experience any problems, turn off ESC and repeat One-Touch.

NOTE: Whenever the One-Touch Set-Up is performed, the speed control will

automatically revert back to the factory-default settings.

If you are planning to use an external receiver battery pack with the M2 Dig 3S ESC

to power the electronics you need to do the following:
1. Plug the external 5 cell (1.2VDC/cell) receiver battery pack into the battery

slot of the receiver.

2. To turn the vehicle ON, switch the receiver pack ON. Then, turn the ESC’s

switch ON, then OFF to allow the ESC to be powered by an external source.

3. To turn the vehicle OFF, turn the receiver pack’s switch OFF.
ALTERNATIVE METHOD
1.
Plug the external 5 cell (1.2 VDC/Cell) receiver battery pack into the battery

slot of the receiver.

2. Unplug the ESC’s red wire from the input harness going to the receiver.

Insulate the red wire to keep it from shorting.

3. To turn the vehicle ON, switch the receiver pack ON, then turn the ESC’s switch ON.

4. To turn vehicle OFF, turn ESC’s switch OFF, then turn receiver pack’s switch OFF.
