• IR Camera inside Guns • Solenoid Valves • 55" HD Screen
• Bezel IR Emitter Array • Pneumatic Motion Cylinders • Surround Blower Fan
The system operates across three core hardware subsystems:
Optoelectronic Shooting Tracking: IR-based optical cameras inside mounted guns track IR matrix LED arrays surrounding the monitor screen.
Pneumatic Motion Dynamics: An external industrial air compressor feeds air pressure into high-speed solenoid valves that actuate cylinders beneath the seating platform to simulate movement and explosions.
Surround & Ventilation Controls: High-CFM blower fans deliver environmental air bursts (wind effects) synced to on-screen gameplay.
🛠️ Routine Preventive Maintenance Schedule (Maintenance Rutin)
To maintain air pressure stability, prevent CPU overheating, and keep motion actuators smooth, follow this routine maintenance protocol:
[ DAILY ] ───────────────────► Drain Air Compressor Water & Moisture
[ WEEKLY ] ──────────────────► Clean Cabinet Blower Ventilation Filters & Grilles
[ MONTHLY ] ─────────────────► Deep Clean CPU Mainboard, Heatsinks, & RAM Contacts
[ QUARTERLY ] ───────────────► Inspect Pneumatic Hoses, Solenoids, & Gun Wiring Harnesses
1. Air Compressor Drainage (Drain Kompresor Secara Berkala)
Action: Open the manual drain valve at the bottom of the compressor storage tank daily (or at the end of every operating shift) to evacuate accumulated condensate water.
Why: Moisture buildup inside compressed air lines causes internal corrosion in pneumatic motion cylinders and shorts out solenoid valve coils.
2. Cabinet Blower & Ventilation Cleaning (Membersihkan Ventilasi Blower)
Action: Vacuum and blow out dust from ventilation fan grilles, cabinet intake ports, and motion seat blower fans using compressed air.
Why: Clogged blower vents cause internal cabinet temperatures to spike, triggering thermal throttling or sudden shutdowns during peak play hours.
3. CPU Mainboard Deep Cleaning (Membersihkan CPU Board secara Berkala)
Action: Remove the CPU enclosure cover, blow dry dust off the processor heatsink and cooling fan, and clean board components using 99% Isopropyl Alcohol (IPA).
Why: Arcade dust absorbs ambient humidity and creates conductive bridges across fine IC pins, causing board shorts, frozen graphics, or "No Signal" display faults.

[ 1. GUN FAULTS ] [ 2. DISPLAY FAULTS ] [ 3. MOTION FAULTS ] [ 4. POWER FAULTS ]
• Dirty IR lens • Dusty CPU RAM pins • Low air pressure • Blown main fuse
• Broken gun harness • Loose VGA/HDMI cable • Stuck solenoid valve • Dead PSU / Cable
• Damaged IR sensor • CPU thermal freeze • Loose relay socket • Loose AC socket
Issue 1: Gun Tracking or Trigger Non-Functional (Tembakan Tidak Fungsi)
Symptoms: Crosshairs fail to move on screen, shots miss target positions, or pressing the trigger yields no response.
Primary Causes & Fixes:
Dirty / Obscured Gun Lens: Dust or fingerprints on the optical lens inside the gun barrel block IR reception. Wipe the lens with an IPA-dampened microfiber cloth.
Damaged / Unplugged Bezel IR Array: Verify that all IR LEDs around the screen bezel are emitting light using a smartphone camera (functional IR LEDs glow light purple on camera).
Broken Wiring Harness inside Gun Flex Tube: Constant movement fractures the internal wires inside the gun's flexible steel hose. Perform a continuity check on the gun cable harness and resolder broken signal lines.
Defective Gun Potentiometer / Opto Sensor: Replace worn trigger switches or optical tracking sensors inside the gun housing.
Issue 2: Monitor Displays "No Signal" (Tampilan Monitor No Signal)
Symptoms: Screen powers on showing "No Signal" or stays entirely black while cabinet marquee lights remain lit.
Primary Causes & Fixes:
Shorted / Dirty CPU Board: Dust buildup on RAM modules or graphics processor pins short-circuits boot signals. Remove the RAM stick, clean the gold edge connector pins with a rubber eraser, blow out the slot with compressed air, and re-seat.
Loose Video Cable: Inspect and tighten VGA/HDMI cable connections between the CPU output port and the display board.
CPU Thermal Freeze / Lockup: Overheating causes the GPU/CPU to halt video output. Replace dried thermal paste on the CPU heatsink and ensure the CPU cooling fan spins freely.
Issue 3: Motion Base Does Not Move (Mesin Tidak Gerak)
Symptoms: On-screen action includes explosions and motion triggers, but the pneumatic seat remains completely static.
Primary Causes & Fixes:
Insufficient Compressed Air Pressure: Check the compressor pressure gauge. Pneumatic motion requires at least $5.5\text{--}7.0\text{ bar}$ ($80\text{--}100\text{ PSI}$). Verify air lines for leaks or crimped hoses.
Jammed / Burnt Solenoid Valves: Solenoid valves controlling pneumatic air direction can stick due to moisture or rust. Test solenoid coil continuity with a multimeter ($20\text{--}50\Omega$) and manually actuate the valve bypass pin to check for physical mechanical movement.
Blown Motion Driver Fuse / Loose Relay: Inspect the motion control I/O board inside the lower cabinet and replace blown DC fuses or re-seat loose relays.
Issue 4: Machine Complete Power Failure (Mesin Mati)
Symptoms: Cabinet lights, screen, and CPU are completely unpowered; no sound or illumination.
Primary Causes & Fixes:
Blown Main AC Line Fuse: Check the glass/ceramic fuse inside the rear AC power entry module socket using a multimeter continuity test. Replace with an identical amp-rated fuse (typically
10A / 250V).Damaged Power Cord / Loose Socket: Verify wall outlet voltage and check for loose terminal blocks inside the main AC junction box.
Faulty Switching Power Supply (SMPS): Test DC output terminals on the internal power supply ($+5\text{V DC}$, $+12\text{V DC}$, $+24\text{V DC}$). If output voltage reads $0\text{V}$, replace the power supply unit.
📌 Master Equipment Repair & Troubleshooting Quick Reference
| Arcade / Industrial Machine | Issue / Error Code | Primary Cause | Corrective Action |
