Precautions
- Non-professional personnel are forbidden to carry out product maintenance, inspection or component replacement!
- It is strictly prohibited to carry out product maintenance under the power-on state. Otherwise, there will be an electric shock hazard!
- After all products are powered off, wait for at least the time specified on the product warning label before performing operations such as product maintenance.
- During maintenance, products and components shall be kept away from contact with or attached with flammable articles, and anti-static measures shall be taken.
- The cover plate shall be prevented from falling off. Otherwise, it may cause injury to the product and personnel.
- It is necessary to avoid polluting or damaging the sealing ring. Otherwise, the sealing performance of the product will be affected, and the service life of the product may be shortened and even the computer may be exploded.
Items Subject to Regular Inspection
Parts and components of the iComputer may be subject to aging due to environmental conditions during long-term use, so regular inspection is required. The inspection period shall be once every 6~12 months. The inspection interval can be appropriately shortened according to the actual use conditions.
| Item | Inspection method | Judgment standard |
| PWR | Use a multimeter to check and adjust the voltage between the terminals to control the power supply within the allowable voltage variation range. | DC 24V (-15%~20%) |
| CPU Resources | Regularly check CPU resources | Not more than 60% |
| Equipment surface temperature | Monitor the case temperature using a temperature gun | Below 70°C |
| Fan | Open the protective cover and visually observe the operation of the fan | The fan shall run, and the dust shall be cleaned regularly. |
| Status indicator | Visually observe it, and compare it with the description of indicators | No alarms |
| Ambient temperature | Measure the ambient temperature using a thermometer | Refer to the environment requirements corresponding to the equipment model |
| Measure the ambient humidity using a hygrometer | Refer to the environment requirements corresponding to the equipment model | |
| Check whether there is dust, dirt, salt, and iron filings | Clean up in time and avoid spreading of pollution sources | |
| Check whether there is water, oil, and chemicals. | Clean up in time and avoid spreading of pollution sources | |
| Check whether it directly causes vibration or shock to the main body | It is necessary to isolate the vibration source in time and avoid spreading of pollution sources. | |
| Check whether there are interference sources nearby | ||
| Installation wiring | Check whether the screws of external wiring are loose. | |
| Check whether the external wiring cable is about to break | ||
| Battery alarm | The controller does not have a “Low Battery Voltage” alarm message. | Check whether the expiration date has been exceeded or the service life has been reached. The shelf life is typically 5 years at 25°C and the battery life varies depending on model and ambient temperature. |
