Features And Programming - Perun AB++ Manual

3. Features and programming

To enter the programming mode, press the button on
the device 2 times. First push activates the button,
which is signaled by LED starting to glow green. Quick
second push shortly after the first leads to the
programming mode. Successful entry into the
programming mode will be confirmed by a sound
signal.
Pressing the button will switch the modes, while
pulling the trigger allows to enable, disable, or set
levels for the modes.

Function and
LED color
Burst When this mode is enabled, a 2 to 5 round burst is available instead of fully automatic
fire.
Green
No sound signal while LED glows green means, that the burst is off. 2 to 5 signals
indicate 2 to 5 round bursts accordingly.
Attention! This burst is based on motor current measurements, which is one of few
methods of cycle detection in non-drop-in mosfets. It may not work perfectly in all
replicas, resulting in different number of shots fired in burst than programmed.
AB Active brake (AB) stops the motor after the shot, preventing the spring from remaining
in a compressed state and eliminates double shots on semi in replicas with high rate of
fire ("overspin"). 5 levels of braking strength are available – from 1 (weakest braking)
Blue
to 5 (the strongest). Braking can be also completely disabled. It is advised not to use
braking all the time, if not necessary, or to use it on the lowest possible level, because
strong braking negatively impacts the service life of motor brushes and causes
increased heating.
Tip: Set your replica to semi, press, and hold the button on the unit, then pull the trigger.
This will cause a single shot with strongest AB setting to be fired, making sure the main
spring remains uncompressed. It is advised to do that when you finish shooting for the
day.
No sound signal while LED glows blue means, that the active brake is disabled. 1 to 5
signals indicate braking levels from 1 (the weakest) to 5 (the strongest).
Attention! While precocking is on, the AB setting becomes irrelevant. However, any
programmed AB setting will be stored in memory and will become effective as soon as
precocking is disabled.
