5.6. PSJ-VZ58 installation

Insert your unit to original position on gearbox. If unit doesn’t fit on gearbox you can adjust it by rasping. After
your unit is placed you must check f or an y c onductive contacts with gearbox. I f there are some conductive
contacts you h a ve to remove them, f or example by rasping the unit or your gearbox , or you can use an insulating
material. Bottom side of unit is insulated by pre-installed insulation foil.

5.8. Checking the cut-of l ever

After you corre c tly install the processor unit check if magnet is inserted in gea r wheels and is directly over the
probe. Everything was tes ted on m ore guns but may happen that the ARES manufacturer changes gearbox or
dimensions of plate without notice. This situation will be necessary to deal with the GRIZZLY manufacturer.

5.9. Inserting the se lector plate

After correct installation of new processor unit reinsert the s ele c tor plate to its original position. Check if magnet is
directly over th e hall probe when selec tor plate is in position „auto“. Ev er ything was tested on m or e g uns but may
happen that that the ARES manufacturer changes gearbox or dim ensions of plate w ithout notice. T his situation will
be necessary to deal with the GRIZZLY manufacturer.

5.10.1 Magnet installation on the trigger

Set the trigger to p os ition, where you want your replica to fire. Put the magnet on trigger as close as possible to
the sensor. If you want sensitive trigger pu t the magnet as c loses t to th e probe when your trigger isn’t pressed
(just before the LEDs light up). LED has never lights in the basic position.

Now stick the magnet. Magnet’s polari ty doesn’t matter.
If needed, you can very gently bend the probe to be very close to magnet when you press trigger, but not to
touch it.

6.2. Unit programming

a) For programming, connect a battery and within 5 seconds pull and hold the tr igger for another 5 seconds.

Entering is confirmed by the motor vib r a ting twice.

b) Next, choose cate gory from menu by pulling the trigger as ma ny times as the category number you w ish to

select indicates. To confirm selecti on, pull and hold th e tr igger for 5 seconds . Your choice is confirmed by
motor vibrating as many times as th e s e lec ted number is and you are now in the su bm enu.

c) When changing fire mode (submen u 3), every trigger pull is followed by m otor vibrating as many time s a s

the number of cur rently selected fire mode indicates. Submenu goes in circle, so number 6 is followed by
number 1. For submenu values, refer to the table below.

d) When you are don e with setting value, pull and hold the trig ge r for 5 seconds to sa ve your settings. Double

vibration confirms successful s a ving and exiting programming fun c tion. Now you’re ready to go. Your
settings stay saved even after disconnecting the battery.

Example of programming:

Then pull the trigger 3 times and then pull and hold for 5s – you‘re entering Fire mode setting. Entering is co nf irmed by three
vibrations. Now pull the trigger - after each pull , v ibr ations will tell you which mode you‘re on. If you pulled the trigger 5 times,
you chose number 5 (mode Burst only - Auto). Five vibrations w il l confirm this selection. To save it, pull and hold the trigger for
5s. Now double vibration sounds, which means the setting is saved and the programming mode has been shut. Your replica is
now ready with selected setting.

First, connect the battery and pull and hold the trig ge r for 5 seconds. Double vibration will sound.

6.3. Motor vibrations meaning (outside programming mode)

• 1x vibration - after th e ba tter y has been connected, unit perf orm s a s elf-check and confirms functionality

• 2x vibration - entering programming mode, savin g a nd exiting programming mode

• 3x vibration - malfunction or damage detected

• 4x vibration - low ba tte r y detec ted

• 6x vibration - entering manual mode

6.4. Manual mode

If your PSJ indicates damage and you are sure it is not mechanical malfunction and you r replica is able to shoot,
you can access manual mode. In this mode, malfunction is ignored and you are allow ed to fire on full au to m od e,
regardless of selected fire m ode or s elector setting.

WARNING! By poor judgement, you can cause more damage to your r e plica and PSJ unit!! T his mode is not
recommended for users without advanced knowledge of A EG replicas principles!

To enter manua l m ode a fter your replica indicates malfu nction, just pull a nd hold the trigger for 10 s e c onds.
Entering is confirmed by 6 vibrations.

7. Troubleshooting

Is your PSJ not working correctly ? Check, where the problem could be:

7.1. Replica is not reacting at all.

• Check if the battery is conn ec ted a nd charged properly. Also check that all wires are connected properly to

all elements – motor , battery.

• If the replica is equipped with safety fuse, check if the fuse hasn’t been blown.

7.2. Replica vibrates when battery is connected, but after that it does not rea c t .

• Problem in trigger s etting. Chec k if your trigger is ins talled properly – ma g net should almost touch the

sensor when the trigger is pu lled. Adjust if needed.

7.3. Selector is set on “semi”, but acts like “auto” is selected.

• Poor selector pla te installation. Check, whether the magnet on the selector is directly abov e the sensor when

selector is set on semi. Adjust if needed.

7.4. Selector is set on “auto”, but acts like “semi” is selected.

• Poor selector pla te installation. Check, whether the magnet on the selector is away from sensor when

selector is set on auto. Adjus t if needed.

• Check if the fire selector is properly moving the selector plate when switched.

• Check if the selector plate is run ning smoothly in the gearb ox. I fit gets jammed, adjust the selector plate or

the gearbox to allow s mooth movement.

7.5. Replica s hoots one or more shots and then vibrates 3 times.

• Cut-off lever not working properly. Check if the magnet is close enough to the sensor, L ED indication will

help you. Adjust if necess ary .

• Check if the selector plate spring is s tr ong enough to retur n the cut-off lev er to its base position. If not, the

magnet might be too far from th e s ensor. The cut-off lever needs to return to its ba se position in all fir e
modes. Using stronger spring is recommended.

• Check if the cut-off lever is installed properly. Im p r ope r installation can r e s ult in lateral movem e nt of cut-off

lever during sh ooting, pushing it ou t of range of the sens or .

7.6. Replica does not shoot, just vi br a t e s 3 times and the vibra tes with each trigger pu ll.

• Mechanical ma lfunction of your r ep lic a has been detected . Check if the m otor a nd the gears are n ot jammed

and are working properly. If you are sure the replica is mechanically ok, you can access manual mode – see
figure 6.4.

• Check if the selector plate is not lifting up the cut-off lever a nd preventing the cycle to be finished. If so, it‘s

necessary to en la rge the area cut off of the selector plate in or der not to lift the c ut-off lever.

7.7. Replica vibrates 4 times repeatedly.

• Your battery is discharged. Change your battery an d do not for get to charge the discharged on e.

• If your battery is charged proper ly, your battery setting ma y be wrong – see figure 6.2 to adjust th e s ett ing.

7.8. If your installation is unsuc c e ssful.

• If your installation is unsuccessful, you can opt to send your r e plica to our installation and repair center.
