airframe structure

The whole machine has a front touch display screen, integrated interface module on the back, cantilever installation position, and optional expansion interface; The interface area is equipped with a detachable cover plate, and cantilevered cables can be stored in pipes and cable trays, with neat wiring and protection against cable bending and wear.

Detailed interface definition and communication scheme

CP39xx is divided into two major hardware versions, with clear distinctions in interface configuration, wiring rules, and transmission schemes. At the same time, it is uniformly equipped with a 24VDC power supply interface.

Universal power supply interface (shared across the entire system)

Adopting a 4-core M12 circular socket, pin 1/4 is+24V, 2/3 is GND, and the rated current of the interface is 16A. The maximum compatible cable diameter is 4 × 0.75mm ²; The voltage drop of the circuit must be strictly controlled, and the input voltage of the panel must not be lower than 22VDC, otherwise abnormal operation may occur. The power supply circuit must be equipped with UL248 standard, maximum 4A fuse, and the power supply must be NEC Class 2 isolated 24V DC power supply.

CP39xx-0000 (DVI+USB Extended Edition)

DVI Extended Interface: a dedicated extended video interface with a built-in signal restoration chip to compensate for signal attenuation caused by long-distance transmission. It can be transmitted up to 50m with a dedicated cable and defines complete TMDS signal, DDC, 5V power supply, hot plug detection, and other pins;

USB Extended Interface: A dedicated interface for USB signal extension, based on Class 5 cable transmission, without network protocol, cannot be connected to external switches/hubs, with a maximum transmission distance of 50m, enabling long-distance extension of USB peripheral signals such as keyboard and mouse.

CP39xx-0010 (CP Link Version 4)

Equipped with an 8-core M12 specification CP Link 4 interface, this bus can simultaneously transmit DVI video and USB 2.0 signals, with a maximum transmission distance of 100m. It provides two switching solutions:

CU8802 adapter box: dual cable solution, the adapter box and panel are independently powered, and the panel must be connected to an external 24V power supply;

CU8803 adapter box: single cable power supply+signal integration solution. It is strictly prohibited to connect external power to the panel, otherwise it will cause hardware burnout.

Optional external USB interface

IP65 protection waterproof USB-A interface, with anti loss screw cap, supports USB 2.0 protocol, can be connected to external devices such as USB flash drives, keyboards, mice, printers, etc. It is available in two installation forms: adapter integrated and body side mounted.

Equipment nameplate

The nameplate indicates the equipment model, version, serial number, production date, screen specifications, touch model, power supply parameters, and CE, FCC, UKCA certification information. The serial number is an important basis for equipment after-sales and spare parts matching.

Installation, wiring and wiring specifications

Transportation and Storage

The internal screen and touch components of the device have weak resistance to impact and temperature difference, and must be transported in original factory packaging; After transportation across temperature zones, it is necessary to let it stand at room temperature. If condensation occurs, it must wait for more than 12 hours before powering on. Storage temperature range -20 ℃~+65 ℃, working environment humidity ≤ 95% RH (no condensation).

Installation requirements for cantilever

Suitable for standard 48mm cantilever pipes, with a diameter tolerance range of -0.1mm to+0.8mm for the pipe body;

The cantilever adapter supports ± 165 ° rotation and ± 20 ° pitch adjustment, with clear torque requirements for installation screws (M6 screw 6Nm, pipe body fastening screw 3Nm, slotted nut 20Nm);

The installation position should avoid direct sunlight to ensure the viewing angle of the screen and device heat dissipation.

Cable wiring rules

The cables need to be threaded into cantilever tubes and dedicated cable trays, and the power and signal lines should be arranged in different zones. They should be fixed with zip ties to prevent the cables from being pulled or worn out when the equipment rotates or tilts;

Models with button expansion, the button cables are connected to the cable tray through M20 gland or 19 pin connectors, and the two wiring methods correspond to different accessory models;

All cable bending angles should not be too large, and bending resistant cables should be preferred for long-term moving parts.

Grounding specifications

The equipment must be equipped with both protective grounding and functional grounding, with a recommended grounding wire diameter of ≥ 4mm ². The PE on the cabinet side should maintain an equal potential with the power supply at 0V, in accordance with EN 60204-1 standard. Good grounding can prevent electric shock, suppress electromagnetic interference, and ensure EMC performance (in accordance with EN 61000-6-2/EN 61000-4 series standards).

Wiring and power on process

Strictly follow the sequence of wiring first, then connecting data lines, and finally connecting power supply; Do not plug or unplug any interfaces during thunderstorms. When connecting external devices with power supply, it is necessary to ensure that both parties have a potential of 0V and PE to avoid potential difference damage to the interface.

Operation, maintenance and upkeep

Guidelines for using touch screens

Only operate with bare hands or dust-free soft gloves, and do not touch the screen with hard objects; Special dust-proof and scratch resistant protective film can be pasted, and the film should be operated in a dust-free environment to avoid bubbles and impurities. The device comes with a built-in cleaning mode that can be activated using the Beckhoff Display Control tool (lasting 5-120 seconds). Once activated, it can be touch locked for easy screen cleaning.

Daily cleaning

Allow the use of glass cleaners, alcohol, and light solvents;

It is strictly prohibited to use abrasives, corrosive cleaning agents, high-pressure water guns, compressed air, and steam cleaning to avoid damaging the IP65 protective layer and touch glass;

During cleaning, the device can be kept powered on by simply locking the touch function.

Regular operation and maintenance

Regularly check the cable fixing status and cantilever fastening screws to prevent loosening;

Check the integrity of the interface waterproof cap and sealing strip to ensure the protection level;

A small number of bad pixels on the screen are within the normal production range and cannot be used as a basis for malfunction.

Dismantling and scrapping treatment

Power off and disassembly: First cut off the external 24V power supply, remove the power and data cables in sequence, loosen the cable tie and cable tray cover, and then disassemble the cantilever tube and adapter; When disassembling the cantilever nut, it is necessary to take protective measures to prevent the panel from falling.

Accessory disassembly: Tool trays, handles, and other accessories can be disassembled and assembled using the bottom M5 screws.

Scrap requirements: Strictly follow local electronic waste recycling regulations, classify and dispose of metal, plastic, circuit boards and other components.

Troubleshooting

Manual compilation of typical fault phenomena, causes, and corresponding solutions:

The device is completely inactive: priority should be given to checking the 24V power supply, fuses, and power cord connections. If there are still abnormalities, contact Beifu after-sales service;

Screen black/intermittent lighting: Check for backlight components and internal hardware faults, need to return to the factory for maintenance;

Touch malfunction: Focus on checking whether the grounding function is reliable. Operators need to wear regular shoes and socks to ensure normal grounding of the human body;
