Status, Warning and Alarm configuration
Green LED: Normal Mode
Throttle signal detection status is non-configurable. It is purely a function of the state of the link
between the radio transmitter and receiver.
Green LED: Configuration Mode
Controller configuration mode is entered as a function of being linked up to the FlexLink
configuration utility. Once in configuration mode, normal mode can only be entered again by
power cycling the Throttle-Tech controller.
Orange LED: Flight Pack Mode
Low voltage warning:
The receiver power bus voltage warning default value is 5.75V and is
configurable from 5.2V to 8.40V to suit the power system in use for the flight pack. Its
purpose is to provide a pre-flight alert if the supply voltage present at the receiver power bus
is below the configured alarm setting.
This warning should be investigated to determine that
the condition of the receiver side battery and/or regulator system is satisfactory to start a
flight,
Critical Voltage Alarm:
The receiver power bus critical voltage alarm is set to a value of
4.8V and is non-configurable at the time of this publication. The purpose of it is to provide a
pre-flight alarm if voltage present at the receiver power bus is at a value below which
receivers and servos may not function correctly. This alarm requires attention before a flight
is attempted.
Orange LED: ESC Battery Mode
Low voltage warning:
The ESC battery low voltage warning is set to a default value of 4.10
volts per cell. At the time of this publication, the setting of this warning parameter is not
configurable. The purpose of it is to provide a pre-flight alert if the ESC battery pack is not
fully charged, or if it may have some other depressed voltage condition that needs attention.
This warning should be investigated to determine if the ESC battery condition is satisfactory
to start a flight. For example, LiPo batteries that are nearing the end of their useful life may
cause this alarm to trigger even when fully charged and may not pose a significant problem.
Operating in colder temperatures may also depress cell voltage enough to falsely trigger this
warning.
Critical Voltage Alarm:
The ESC critical voltage alarm is set to a value of 3.6 volts per cell
and is non-configurable at the time of this publication. The purpose of it is to provide a pre-
flight alarm if the ESC battery pack is charged less than approximately 25% of capacity, or
has some other battery condition that might require attention before a flight is attempted. This
alarm requires attention before a flight is attempted.
