• can be used with spring up to M200 with r a te of f ir e 99rpm

• longer wires, su itable for all replica types

• adjustable rate of fire

• adjustable active brake with possib ility to be complet ely disabled

• compatible with batteries up to 4S / 16.8V

• a screw added to accessories to attach the unit into the gearbox

• new, thicker insulation foil preve nting short circu it

• possible usage of dual sector gears

• layered varnis h coating preventing short circuit

• new service connector

2. Basic information

New generation of PSJ proc es sor unit brings ma ny new functions and easier installation. All the great function of
previous generations ar e kept - contactless magnetic switchin g, powerful MOSFET cooled via the whole gearbox,
active brake fully functional in any mode, programmable burst a nd so on.
On top of that the active brake is now adjustable up to completely disabled, we’ve added advan c ed r a te of fire
settings, energy cons umption is now as low as 3.9mA and ther e a r e man y more new features and updates.

Generation 3 un its are suitable for AE G replicas accordin g to the version of gearbox each unit is des ig ned for.
Units have been tested in gearbox es of following manufacturers*:
AimTop, APS, ARES, ASG Ultimate, Cyma, DBoys, Guarder, RetroArms, SHS, SRC

*Every manufacturer inno vat es their products over the time, so there is po ssi bil ity, that the gearbox tested by us is different from yours. However
this only means, that your installation might require some minor adjustments.

3. Functions overview

3.1. Fire modes

• 6 pre-set fire modes

• configurable burst mode - f r om 1 up to 255 BBs shot on one quick trigger pull, th is setting works in all

modes containing burst

• automatically s witches from bur s t to full auto when trigger pulled for longer time, without any delay

• modes are fully programm a ble by the trigger (see figure 6.2.)

3.2. Rate of fire

• allows you to set de la y between the two following shots

• allows smooth ra te of fire setting

• programmable by trigger (see figure 6.2.)

3.3. Special funct ions

• default settings reset: You can simply reset all settings to their default values by tr igger ( s ee figure 6.2.)

• manual mode: If your PSJ indicates damage and you are sure it is not mechanical and your replica is able to

shoot, you can access manual mode in which malfunction is ignored. You can then fire on full auto mode
only (see figure 6.4).

• WARNING! By poor judgemen t, you can cause more damage to your replica a nd the unit!

3.4. MOS-FET

• no mechanical switch, switchin g is contactless

• faster trigger response

• increased rate of fire and batter y life

• maximum current up to 202A constant and 808A in peek

3.5. Active brake

• stops motor immediately with piston in default position and spring loos e (when 100% set)

• increases lifet im e of piston, sprin g a nd many other parts

• always finishes whole rotation of g ea r wheels

• fully function a l in all fire modes

• adjustable by steps of 10%

• possibility to completely disable a c tive brake (set 0%)

3.6. Malfunction detection

• unit detects mechanical damage and disables shooting to prevent any other damage

• user is warned by motor vibrati on s ( s ee figure 6.3.)

3.7. Li-Pol/Li-Ion/Li-Fe battery check

• when lithium ba ttery is discharged, unit warns user by motor vibrations (see figure 6.3.)

• battery type needs to be set – eas ily done using trigger itself (see figure 6.2.)

• warning is off f or Ni-MH, Ni-Cd batteries

3.8. Realistic trigger operation

• trigger sensitivity can be set durin g installation to best fit your demands

3.9. Anti-reversal latch

• solves problem with double shot on se m i

• anti-reversal latch may not be needed if the mo tor is powerful enough (not recom mended)

3.10. All this hi dden inside your gearbox

• the whole unit is installed inside your gearbox, replac ing trigger contacts

• only two power wire s c ome from gearbox

• unit is equipped with LED indication of correct installation for easier installation

4. Technical parameters

• Top quality silicone wiring. 1mm

• Powerful MOS FE T with maximum curr e nt up to 202A constant and 808A in peak allows use almost without

any restrictions .

• MOSFET is effectively cool ed by the whole gearbox.

• The whole unit is coated in multiple layers of varnis h for maximum durability even in poor conditions.

• Replica‘s rate of fire is limited by gearbox components and technical s pe c ifications. PSJ unit itself is able to

do up to 500 000 cycles (shots) per s ec on d. Unit is tested for 99 cycles (shots) per second.

• Current consu m ption of unit in standby mode is as low as 3.9mA.

5. PSJ-M3 installation

! PSJ should be installed by specia lists only!

Advanced knowle dge of AEG replic a s is crucial!

Basic knowledge of electronics and s oldering skil ls are needed as well .

Never use soldering gun!

Manufacturer takes no responsi bility for damages c a used by unprofessiona l installati on!

5.1. Preparation

For PSJ-M3 installation, take ge a r b ox out of your replica, open it and remov e all of its content.

Pict.1: Gearbox with all of its content removed

5.2. PSJ-M3 mounting

Insert your unit into gearbox, bottom side first. If it does not fit properly, you need to adjust gear box. Prepare
gearbox for smoo th unit insertion. After your unit is place d, check for any c onductive contacts with g ea rbox. If
there are any, you need to insulate th em ! You can sharpen your gearbox or you ca n use some insulation m a te r ial.
Bottom side of un it is insulated by pre-installed insul ation foil. Before final insertion, r em ove protective f oil from
heat-conducting foil. Now you can fix the unit with a screw and organise cables. Never sharpen the unit.
