    Change parameters page 1/3 Orange stripe = not green stripe = paired paired, Paired = loads parameters from Leviathan. Change parameter -> shows „writting...„ in the green stripe. Text dissapear -> parameter is saved Fire modes with Selector on safe/semi/auto: - SAFE: no responding to the trigger pull.
  • Page 16 Change parameters page 2/3 Active Brake: It uses the excess energy from the motor to stop it. Spring is fully released, parts in gearbox aren‘t under strain. Higher braking is for weapons with high RoF. Braking eff ect is more powerful with torque motor. Note: Lower braking intensity spares the motor coils.
  • Page 17 Change parameters page 3/3 External input: see manual at page 3. Works with Input terminal - - OFF: Every signal to Input terminal is ignored. - External trigger: gun trigger is disabled and repla- ced by micro switch connected to Input (SIG and GND) - Burst-3 trigger: micro switch connected to Input (SIG and GND) make 3 burst fi re when it is pressed.
