Technology, Radio Priority Circuitry, & One-Touch Set-Up are all trademarks of Novak R/C, Inc. The
M2 Dig’s dual independent motor control design and dig 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:
When active (see Field Guide to turn ON/OFF), the built-in Novak Smart-Stop Voltage
Cut-Off Circuitry lets you safely use 2S or 3S Lithium Polymer (LiPo) or Lithium Iron
Phosphate (LiFe) battery packs by cutting off the speed control’s throttle output
when the critical safety voltages are reached.
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
interrupting, or “blipping,” the throttle output as an early warning that the battery’s
voltage is getting low and the throttle output will soon be completely shut off.
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.
When the ESC is switched ON, the Yellow & Red LEDs will flash
together 2 or 3 times to indicate LiPo/LiFe Cut-Off is ACTIVE.
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. See
CUSTOM PROGRAMMING options on the Track Guide to properly adjust this setting.
With ESC connected to (at least) a receiver and a charged battery pack, and the
transmitter’s Aux/3rd channel (3Ch required for Dig) set to its
middle
position
:
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.
