3.3 LED's, errors and protection
In normal use the LED will illuminate as follows:
a. If the throttle control is in the neutral position, neither the red
or green LED will illuminate.
b. The red LED will illuminate if the vehicle is driving forwards or in
reverse. If the vehicle is braking, the red LED will flash rapidly.
c. The green LED will illuminate when the vehicle is at full throttle
either forwards or in reverse.
In certain circumstances the ESC will omit an acoustic tone to warn
you of a problem:
1. On switching on, the ESC will check the battery pack
voltage and if it falls outside the correct values it will omit
double bleeps followed by a 1 second pause: "beep-beep-,
beep-beep-, beep-beep-"
2. If the ESC does not receive a signal from the transmitter it will
omit single bleeps followed by a 2 second pause: "beep-,
beep-, beep-"
The ESC has ben equipped with a series of protective circuits to
ensure safe operation:
1. Low voltage cut-off:
If the voltage drops below the set value for more than 2 seconds
the ESC will switch the motor off. Please note that the motor can-
not be started again if the voltage is below 3.5 Volts per cell.
Problem
The motor will not rotate after switching
on. No acoustic signal is heard.
The motor will not turn after switching on.
The ESC omits double bleeps with a 1 sec-
ond interval.
The motor will not turn after switching on.
The ESC omits single bleeps with a 2 sec-
ond interval.
The motor turns in the wrong direction.
The motor suddenly stops turning.
The motor stutters or runs irregularly.

If a NiCd or NiMH pack with a voltage of between 9 and 12 Volts
is connected, the ESC will treat is as if it was a 3 cell LiPo pack. If
the pack voltage is below 9.0 Volts, the ESC will react as if it was a
2 cell LiPo pack. For example, if a NiMH pack is connected with a
nominal voltage of 8 Volts and the cut-off value is set to 2.6 Volts
per cell, the ESC will switch the motor off at 5.2 Volts (2 X 2.6 V).
This will protect the NiMH packs from 'deep discharge'.
2. Temperature cut-off
If the internal temperature of the ESC rises above 95°C for more
than 5 seconds the motor will switch off. This function can be
disabled which may be useful if racing.
3. Signal loss
If the signal is lost for more than 0.2 seconds the ESC will switch
the motor off.
5. Trouble shooting
Although this ESC has been subjected to the most stringent qual-
ity control it is possible that you may experience a problem during
operation. In this case please use the table below to assist in fault
finding.
Cause
The battery pack or battery pack connectors
are faulty.
The input voltage is too high or too low.
.
No or a poor receiver signal.
The motor connecting cables are swapped.
The battery voltage is too low.
No signal.
One of the connectors is loose.
The receiver has intermediate interference.
Solution
Check all of the connectors and the battery
pack.
Check the battery pack voltage.
Check both the transmitter and receiver as
well as the ESC connecting cable.
Swap 2 of the ESC/motor connecting ca-
bles.
Charge the battery pack.
Check the transmitter, receiver and all of
the cables.
Carefully check all of the connectors.
Switch the system off and then on. If the
interference persists, operate the model in
another location.
