EDGE ESC LOCK HARNESS AND KEY

Mounting

The socket may be 
installed through a 
panel or secured inside a 
fuselage.

Wiring Diagram

Connect the white wire to the Aux Line (white wire) on 
an Edge ESC.

Connect the red “+” wire to any servo wire with a Y 
harness.

Warning

Edge Arm Lock mode is intended as a 
secondary safety device. It is not intended 
to replace safe practices or careful handling 
of your RC power system, vehicle, and 
transmitter.

Edge Arm Lock is only operational if you 
have successfully conigured the Edge ESC 
using Castle Link software.

Edge Arm Lock requires that the AUX LINE 
of the Edge ESC receives a voltage between 
1.8V and 8.4V to arm. Failure of the power 
source (0 volts) will cause the ESC to enter 
Arm Lock mode.

Operation

Key in socket OR disconnected wire in socket harness 
= ARM LOCKED.

A properly programmed and wired Edge will be 
incapable of arming when the key is in the socket.

If the key is placed in the socket or the arm lock socket 
loses power, the ESC will go into a locked state - even 
if it is running.

Key r power to socket = ARM UNLOCKED. ESC 
must receive low throttle signal to arm and run.
