Example of programming: First, I connect battery and press and hold trigger for 5 seconds. Double vibration
sounds. I press trigger 3 times and then press and hold for 5s - I'm entering Fire mode setting. Enter is signalized
by triple vibration. I press trigger, after every press vibrations tell me which mode I'm on. I pressed trigger 5
times, which means I choose number 5 (mode Burst only - Auto). Five vibrations sound, so I press and hold
trigger for 5s. Now double vibration sounds, which means my setting is saved and I exited programming. My
replica is ready with selected setting.
6.3. Motor vibrations meaning
1x vibration: each time you connect battery - states, that unit is ready
2x vibration: entering setting mode, saving and exiting setting mode
3x vibration: malfunction or damage detected
4x vibration: low battery detected
6x vibration: entering manual mode
6.4. 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 this mode, malfunction is ignored and you can fire on full auto, regardless of selected fire
mode.
WARNING! By poor judgement, you can cause more damage to your replica and PSJ unit!! This mode is not
recommended for users without advanced knowledge of AEG replicas principles!
To enter manual mode after your replica indicates malfunction, just press and holt trigger for 10 seconds. Entering
is confirmed by 6 vibrations.
7. Troubleshooting
Your PSJ-M2 is not working correctly? Check, where the problem could be:
7.1. Replica not working at all.
Check if the battery is connected and charged properly. Also check that all wires are connected properly to
all elements – motor, battery.
Check fuse funcion, if is connected in replica.
7.2. Replica vibrates when battery is connected, but after that it does nothing.
Problem in trigger setting. Check if your trigger is installed properly – magnet should almost touch the
probe when trigger is pressed. Adjust if needed.
7.3. Selector is on „semi“, but acts like „auto“ is selected.
Bad selector plate installation. Check, that magnet on selector is directly above the probe when selector is
set on semi. Adjust if needed.
7.4. Selector is on „auto“, but acts like „semi“ is selected.
Bad selector plate installation. Check, that magnet on selector is out of sensor when selector is set on
auto. Adjust if needed.
Check if fire selector is poperly moving selector plate, during fire slection.
Check if selector plate is smoothly runnig in gearbox grooves. In some cases it can stammer against
bearings. If this is happenig adjust selector plate or gearbox.
7.5. Replica shoots one or few shots and then vibrates 3 times.
Cut-off lever not working properly. Check if the magnet is close enough to the probe. LED indication will
help you (see pict.5). Adjust if needed.
Check if selector plate spring has enough power. Problem is usually in burst position when selector plate is
farther from cut-off lever and spring has not enough power. Cut-off lever needs to be in basic positon in all
fire modes. Stronger spring is better
Check if cut-off lever is properly installed. Shooting can cause lifting up of cut-off lever and that can couse
that magnet is out of probe.
(Example: gearbox with unit is laying on table and you are looking at it. Cut-off lever can´t move to you
and back.
7.6. Replica not shooting, just vibrates 3 times.
Mechanical malfunction of your replica. Check if motor and gears are not blocked and are working
properly. If you are sure it is ok, you can access manual mode – see figure 5.4.
Check if selector plate is not lifting up cut-off lever and stopping end of cycle. If yes, is necessary to
enlarge space (on selector plate) for cut-off lever.
