Frequently Asked Questions

A Stainless Steel Panel PC is an industrial-grade computing device with a touchscreen display, housed in a stainless steel enclosure designed for harsh environments that require protection against water, dust, chemicals, and frequent cleaning. These systems are particularly suitable for food processing, pharmaceutical, medical, and other applications requiring hygienic and washdown-compatible equipment.

These Panel PCs feature hygienic stainless steel designs with minimal crevices, waterproof connectors, IP66/IP69K protection against powerful water jets and washdowns, resistance to cleaning chemicals, and full-flat touchscreens that prevent debris accumulation. They meet industry standards for food production environments and can withstand the rigorous cleaning protocols required in such facilities.

IP66 provides protection against powerful water jets from any direction, while IP69K offers the highest level of protection against close-range high-pressure, high-temperature water jets (such as steam cleaning). Panel PCs with IP69K ratings can withstand industrial washdown procedures with high-pressure water (80-100 bar) at high temperatures (up to 80°C), making them suitable for environments requiring stringent sanitation processes.

Fanless operation means the system dissipates heat through passive cooling methods (like heat sinks) without moving parts. This design is crucial for Stainless Steel Panel PCs as it eliminates ventilation openings that could compromise IP ratings, prevents dust circulation in clean environments, reduces maintenance needs, improves reliability in harsh conditions, and eliminates noise in sensitive environments.

Wide voltage input (typically 12V-24V or 12V-26V) allows Panel PCs to operate reliably with various power sources and in environments with fluctuating power conditions. This flexibility accommodates different industrial power standards, handles voltage drops in long cable runs, provides tolerance against surges or sags, and eliminates the need for additional power conditioning equipment in challenging settings.

When installing in food processing environments, consider: mounting location relative to food handling areas, accessibility for regular cleaning, proper sealing of any panel cutouts, positioning to minimize potential food or liquid splatter, using appropriate stainless steel mounting hardware, ensuring cable management maintains hygiene standards, and verifying the installation doesn't create any crevices or hard-to-clean areas.

In washdown environments, use waterproof cables with appropriate IP ratings, employ stainless steel cable glands or waterproof strain reliefs, create drip loops to prevent water tracking to connections, use cables specifically designed for the specialized M12 connectors, secure cables to prevent stress on connections, and consider protective conduits for exposed cable runs to maintain the hygiene and protection rating of the installation.

Consider the appropriate voltage within the specified range (typically 12V-24V or 12V-26V), selecting a power supply with sufficient wattage rating (usually 60W or higher), ensuring the power supply has appropriate certifications for the installation environment, using waterproof power connections or appropriate enclosures for power supplies in washdown areas, and possibly implementing an uninterruptible power supply (UPS) for critical applications.

To maintain IP66/IP69K rating: use proper mounting hardware with appropriate gaskets or seals, ensure any enclosure cutouts follow manufacturer specifications and are properly sealed, utilize the supplied waterproof cables or appropriately rated alternatives, always attach protective caps to unused ports, verify that the air pressure relief valve (if equipped) is properly installed, and regularly inspect seals and connections for wear or damage.

For touchscreen issues: ensure the screen is clean and dry, check if using appropriate touch input (finger for PCAP, stylus/finger for resistive), run the operating system's touch calibration utility, verify touch drivers are properly installed and updated, check for physical damage to the screen surface, test in a different application to isolate software-specific issues, and for persistent problems, contact technical support as the touchscreen controller may require replacement.

If experiencing overheating: verify the ambient temperature is within the specified operating range, ensure the unit has adequate clearance around it for passive cooling, check that mounting hasn't restricted heat dissipation from the rear of the unit, clean any dust or debris from cooling fins or heat sinks if accessible, check resource-intensive applications that may be causing high CPU usage, and consider adding auxiliary cooling to the enclosure while maintaining IP protection for installations in high-temperature environments.

For M12 port connectivity issues: verify proper alignment of connector pins before tightening, check for damage to pins or connector threads, ensure connectors are fully seated and properly tightened, test with alternative cables known to be working, verify device drivers are installed correctly, check BIOS/UEFI settings to confirm ports are enabled, and inspect the ports for corrosion or contamination that might affect connectivity.

If the unit won't power on: check power supply connections and verify output voltage is correct, inspect power cables for damage, verify the power button is functioning correctly, check if the power mode setting (AT/ATX) matches your configuration, disconnect all peripherals to isolate potential issues, look for LED indicators that might signal power presence, and if available, try an alternative power supply meeting the specified requirements to determine if the power supply is the issue.
