Your model’s XL-5 Electronic Speed Control
now features Low-Voltage Detection
The Low-Voltage Detection circuitry constantly monitors the battery
voltage. When the battery voltage begins to reach the minimum
recommended discharge voltage threshold for LiPo battery packs, the
XL-5 will limit the power output to 50% throttle. When the battery
voltage attempts to fall below the minimum threshold, the XL-5 will
shut down all motor output. The LED on the speed control will slowly
blink red, indicating a low voltage shutdown. The XL-5 will stay in this
mode until a fully charged battery is connected.
Your model includes a Power Cell NiMH battery. The XL-5 speed
control’s Low Voltage Detection has been disabled for best performance
with this battery. The speed control’s LED will glow red when it is turned
on, indicating Low Voltage Detection is disabled. Be certain to activate
Low-Voltage Detection if you install LiPo batteries in your model.
Never use LiPo batteries while Low-Voltage Detection is disabled.
Verify that Low-Voltage Detection is DISABLED:
1. Turn on the transmitter (with the throttle at neutral).
2. Connect a fully charged battery pack to the XL-5.
3. Press and release the EZ-Set button to turn the XL-5
on. If the LED is solid red, then the Low-Voltage
Detection is DISABLED (not safe to use LiPo
batteries). If the LED is solid green, then Low-
Voltage Detection is ACTIVATED.
To activate Low-Voltage Detection (LiPo setting):
1. Make sure the LED on the XL-5 is on and shines red.
2. Press and hold the EZ-SET®
button (the LED will turn off) (A).
After ten seconds, the motor will
beep twice and the LED will shine
green. Release the button (B).
3. Low-Voltage Detection is now ACTIVATED.
To disable Low-Voltage Detection (NiMH setting):
1. Make sure the LED on the XL-5 is on and shines green.
2.
Press and hold the EZ-SET® button
(the LED will turn off) (A). After
ten seconds, the motor will beep
three times and the LED will shine
red. Release the button (B).
3. Low-Voltage Detection is now DISABLED.
Throttle Neutral Protection
Your model’s XL-5 speed control also features Throttle Neutral
Protection. If the transmitter’s throttle trim setting is changed while
the speed control is switched off, Throttle Neutral Protection prevents
the speed control from activating the motor until the throttle trim is
corrected. Throttle Neutral Protection also prevents the model from
suddenly accelerating if the speed control is switched on while the
transmitter’s trigger is being held. When the trigger is returned to
neutral, the XL-5 will operate properly.
LED Codes and Protection Modes
• Solid Green:
XL-5 power-on light. Low-Voltage Detection is ACTIVATED
(LiPo setting).
• Solid Red:
XL-5 power-on light. Low-Voltage Detection is DISABLED
(NiCad/NiMH setting). Never use LiPo batteries while Low-Voltage
Detection is disabled.
• Fast Blinking Red:
The XL-5 is equipped with thermal shutdown
protection to guard against overheating caused by excessive current
ow. If the operating temperature exceeds safe limits, the XL-5 will
automatically shut down. Let the XL-5 cool. Make sure your model is
properly geared for the conditions (see pages 20-21 in the manual).
• Slow Blinking Red (with Low-Voltage Detection on):
The XL-5 has
entered Low-Voltage Protection. When the battery voltage begins
to reach the minimum recommended discharge voltage threshold
for LiPo battery packs, the XL-5 will limit the power output to 50%
throttle. When the battery voltage attempts to fall below the minimum
threshold, the XL-5 will shut down all motor output. The LED on the
speed control will slowly blink red, indicating a low-voltage shutdown.
The XL-5 will stay in this mode until a fully charged battery is connected.
• Fast Blinking Green:
The XL-5’s LED will blink fast green if Throttle Neutral
Protection is activated, or if the speed control is not receiving a signal.
Make certain the speed control is properly plugged into the receiver and
the transmitter is switched on. If this does not restore normal operation,
then the XL-5 is indicating the transmitter’s Throttle Trim (see page 28) is
incorrectly set. Reset the throttle trim to the “0” position.
