OEM version

Products with OEM indicate is determined for experts. T he lower price is compensated by absen c e of pa c kaging,
extensive manual and some universal accessories. If you are buying an OEM version we assume that you are
expert of AEG and in case of complain t will be detailed examined da m a ge by faulty installation.

1. GEN.3 news overview

• simplified unit installation

• simplified magnet installation – polarity doesn’t a ffect functionality

• lower energy con s umption, as low a s 3.9mA

• 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 possibility to be completely 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 processor unit brings m any new functions a nd easier installation. All the great f unction 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 and 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

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 a ny delay

• modes are fully programma 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 r es et a ll settings to their default values by trigger (see 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 ( s ee 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 gea r b ox components a nd technical spec 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-VZ58 installation

! PSJ-VZ58 gen.2 should be installed by specialists only !

Advanced knowle dge of AEG replic a s is. Also basics in electronics and soldering skills a r e needed.

Never use soldering gun! Manufact ur e r ta k e s no responsibi lity for damaged caus ed by unprofessional

installation!
