An intelligent control cabinet is an automatic control device widely used in industries such as industrial, medical, domestic water supply, wastewater treatment, transportation, metallurgy, chemical engineering, agriculture, irrigation, and machinery. It boasts high reliability, safety, and strong anti-interference capabilities. Despite these advantages, it is prone to malfunction and loss of control if exposed to harsh environments or operated improperly, potentially leading to incorrect machine operations. Therefore, to enhance the reliability and lifespan of the equipment,PLCWhen used as an intelligent control cabinet, several issues should be noted.
1 .In terms of working conditions, regarding temperature, generally, it is required to be0Degree~55Approximately degrees. Please note the cabinet cooling if the temperature exceeds this range. Natural ventilation can be achieved through the louver above the cabinet, or air ventilation circulation can be achieved inside the cabinet with a fan. If this is still ineffective, please cool the entire cabinet with an air conditioner. Below0At times, a small heater needs to be installed in the refrigerator to heat the temperature to the specified range.
2 .Humidity guaranteed to keep the air humidity below85%No condensation. Regarding air quality, please avoid the presence of dust, cotton dust, corrosive gases, and flammable gases.PLCInstalled in a control cabinet with good sealing.
3 .When using the intelligent control cabinet, avoid direct sunlight and rainwater splashes. Water entering the tank may affect the normal operation of the components. In severe cases, it could lead to short-circuiting in electrical equipment, posing a risk of electric shock and even endangering personal life safety.
4 .Continuous or frequent vibration or impact on the intelligent control cabinet may cause the components inside to loosen and have poor contact, leading to equipment failure. Therefore, please keep it away from strong vibration and impact sources during installation. In cases where vibration and impact cannot be avoided, anti-vibration rubber rings can be used for vibration reduction.
5 .During operation, ensure that the air circulation inside the cabinet is smooth, that the installation positions of the components are reasonable, and that it is convenient to inspect and maintain in case of future malfunctions. Additionally, pay attention to transformers, inverters,PLCAnd leave room for future system expansion to prevent mutual interference.
