3.3. Special functions 

 

reset to default settings - you can simply reset all settings to their default values by trigger (see figure 
5.2.) 

 

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 and you can fire on full auto mode 
only - see figure 5.4 (WARNING! By poor judgement, you can cause more damage to your replica and the 
unit!) 

3.4. Mos-fet 

 

no mechanical switch, everything is contactless 

 

faster trigger response 

 

increases rate of fire as well as battery life 

 

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

3.5. Active brake 

 

active brake turn-off possibility 

 

settable active breaking  by 10% 

 

when brake setted on 100% stops motor immediately with piston in default position and spring loose 

 

increases lifetime of piston, spring and many other parts 

 

always finishes whole rotation of gear wheels 

 

fully functional in all fire modes 

3.6. Malfunction detection 

 

detects mechanical damage and blocks trigger from causing any more damage 

 

warns user by vibrating (see figure 5.3.) 

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

 

when lithium battery is discharged, warns user by vibrating (see figure 5.2.) 

 

setting battery type by trigger  

 

can be switched off for Ni-MH, Ni-Cd batteries 

 

warns user by vibrating (see figure 5.3.) 

3.8. Realistic trigger operation 

 

trigger sensitivity can be set during installation to best fit your demands (see figure 5.5.) 

3.9. Anti-reversal latch 

 

not needed if your motor is powerful enough (it is recommended to keep it) 

 

solves problem with double shot on semi 

3.10. Everything is set inside your gearbox 

 

whole unit is inside your gearbox, replacing trigger contacts 

 

only two power wires comes from gearbox 

 

for easier installation, unit equipped with indication of correct installation 
 
 
 

 

4. Technical parameters 

 

Only high quality silicone wiring is used. 1mm2 in cut and ampacity up to 42A constant. 

 

MOSFET with maximum current up to 202A constant and 808A in peak allows use without any restrictions. 

 

MOSFET is efectively cooled by whole gearbox. 

 

Whole unit is coated by varnish for maximum lifetime even in bad conditions. 

 

Replica´s rate of fire is limited by gearbox components and technical specifications. PSJ unit is able to 
make up to 500 000 cycles (shots) per second. Unit is tested on 99 cycles (shots) per second. 

 

Current consumption of unit in stand by mode is 3,9mA. 

 

Dimensions only 22x21x11mm.
