HIMax X-FAN system fan

Core Features and Classification of Products

(1) Product positioning and functionality

X-FAN is a necessary component of the HIMax system, installed directly above the substrate to provide heat dissipation for modules with ventilation openings on top and bottom. Hot air is discharged upwards, and sufficient heat dissipation space needs to be reserved;

Core functions: heat dissipation and ventilation, fan operation monitoring (voltage/speed/line status), fault alarm (LED indicator light+fault relay).

(2) Model classification and adaptation relationship

Divided into 8 models based on installation method and air volume noise, suitable for different substrates, as follows:

Model, installation method, fan quantity, suitable substrate, air volume characteristics, noise characteristics, recommended usage scenarios

X-FAN 10 01 Backboard 2 X-BASE PLATE 10 01 High (240~440m ³/h) High (≈ 63dB (A)) High temperature environment, unmanned scene

X-FAN 15 01 Backboard 3 X-BASE PLATE 15 01 High (360~660m ³/h) High (≈ 65dB (A)) High temperature environment, unmanned scene

X-FAN 15 02 19 inch rack 3 X-BASE PLATE 15 02 high (360~660m ³/h) high (≈ 65dB (A)) high temperature environment, unmanned scene

X-FAN 18 01 Backboard 4 X-BASE PLATE 18 01 High (480~880m ³/h) High (≈ 67dB (A)) High temperature environment, unmanned scene

(3) Key components and functions

Identification label: including product name, conformity mark, barcode, part number, software and hardware versions, operating voltage, explosion-proof specifications (if applicable), and production year;

Mechanical structure: Made of aluminum alloy, with left and right mounting flanges and a rotatable cover plate (to be opened when installing/disassembling modules);

Power supply design: Supports L1+/L2+redundant power supply. When using a single power supply, jumper wires need to be connected between terminals 3 (L2+) and 5 (L1+) to avoid monitoring false alarms;

Fan monitoring: Real time detection of voltage abnormalities, fan stalling, low speed, line interruptions, and other faults. When a fault occurs, the red Error LED lights up and the fault relay is released;

Indicator lights: 2 LEDs on the front, green Run LED (lit when power supply is normal), red Error LED (lit when faulty).

Installation and startup process

(1) Installation preparation

Tools: 0.4 × 2.5mm flathead screwdriver, wire stripping pliers;

Installation kit: M6 bolts and washers are required for backplate installation (not included in the supply scope), and HIMA special kit (M 2212, part number 99 0000115) is required for 19 inch rack installation;

Wire requirements: The maximum cross-sectional area of single strand/multi strand/thin stranded wire is 1.5mm ², and the thin stranded wire needs to be equipped with a wire end sleeve, with a stripping length of 6mm and a tightening torque of 0.2~0.25Nm.

(2) Installation steps

Key steps of installation method

Backboard installation (such as X-FAN 10 01): 1. Use M6 bolts to fix the fan on the backboard above the substrate; 2. Confirm the spacing between threaded holes according to the dimension diagram; 3. When the bolt is tightened halfway, clamp the fan into the base plate locking bolt; 4. Tighten the bolts and establish a conductive connection between the backplate and the ground; 5. Verify the firmness of installation

19 inch rack installation (such as X-FAN 15 02): 1. Secure the fan with cage nuts, M6 × 16 cross screws, and washers from a specialized kit; 2. Insert the fan into the locking bolt of the substrate; 3. Tighten the fasteners at the four elongated holes; 4. Establish a conductive connection between the fan and the ground; 5. Verify the firmness of installation

(3) Power supply connection

Peel off the insulation layer of the wire (length 6mm);

Connect the power supply according to the terminal definition: terminals 1 (L1+), 2 (L1-), 3 (L2+), 4 (L2-);

When using a single power supply, a jumper should be connected between terminals 3 and 5;

Tighten the terminals with a screwdriver to ensure a reliable connection.

(4) Installation spacing requirements

High wind volume model (X-FAN 10 01/15 01/18 01): 1RU (44.45mm) spacing needs to be reserved above and below;

Low air volume model (X-FAN 10 03/15 03/18 03): A spacing of 2RU (88.9mm) needs to be reserved above and below;

19 inch rack model (X-FAN 15 02/15 04): The rear should have an opening and the space should be unobstructed.

Operation and maintenance

(1) Operation monitoring

No additional operation is required, the status is determined by the front LED: green constant light=normal operation, red constant light=fault;

Fault alarm can be achieved by connecting the fault relay contact to the sound and light alarm (maximum current 4A).

(2) Maintenance requirements

Replacement cycle: Replace every 6 years at normal operating temperature (<40 ℃); Replace every 3 years in high temperature environments (>40 ℃), and it is recommended to return to the factory for maintenance;

Replacement specification: The same model or an alternative model approved by HIMA must be used. When replacing, the requirements of the System Manual and Safety Manual must be followed;

Maintenance permission: Only HIMA manufacturers have the right to repair, and users are not allowed to disassemble and repair on their own;

ESD protection: Maintenance personnel must have ESD protection knowledge to avoid electrostatic damage to electronic components.

Transportation and disposal

Transportation: Original packaging is required to prevent mechanical damage and electrostatic discharge. Original packaging is only used for storage and additional protection is required during transportation;

Disposal: Industrial customers are responsible for the environmental disposal of scrapped hardware and can apply to HIMA to sign a disposal agreement. All materials must be disposed of in accordance with ecological and environmental requirements;

Deactivation: Disconnect the power to complete the deactivation.
