The FFU centralized control system can monitor a variety of operating conditions. However, the more monitoring items the better, but should correspond to the operation management and maintenance needs. If you only record the rotational speed, you may not be able to detect dust buildup on the filter or a drop in air volume. If only the switch status is recorded, it may not be possible to determine whether the device is operating normally.
The selection of monitoring projects depends on the project's requirements for cleanliness, operational stability and maintenance efficiency. Reasonable monitoring projects can help operators detect abnormalities in time, arrange maintenance and record operating data.
Aili Industrial has complete self-research capabilities in FFU control systems and can configure monitoring functions according to project requirements. For the basic configuration of FFU control and communication, please refer toAili Industrial FFU fan filter unit。
Running status is the most basic monitoring item. This includes whether the device is running, down, and in local or remote mode. The operating status can help operators confirm whether the equipment is running as planned.
If the group control shows offline but the fans are still running, it means that the operating status and communication status need to be distinguished. For relevant judgments, please refer toFFU group control shows offline but the fans are still running。
Speed is the main control parameter for FFU operation. Group control systems can usually read or set the RPM percentage. RPM can reflect whether the equipment is operating as set.
The air volume reflects the air supply effect more directly than the rotational speed. If the FFU adopts constant air volume control, the system can monitor the air volume or related feedback parameters. If constant speed control is used, the air volume may decrease after dust accumulates on the filter. At this time, it can be judged based on pressure difference or wind speed monitoring.
For projects that require stable air supply, air volume or wind speed feedback can be configured.
The filter pressure difference reflects the dust accumulation status of the filter. The gradual increase in pressure difference indicates an increase in filter resistance. When the pressure difference reaches the set value, replacement or maintenance is prompted.
Differential pressure monitoring can help operators schedule filter replacements to avoid insufficient air volume or increased energy consumption. A sudden drop in differential pressure may indicate filter bypass or damage. For relevant judgments, please refer toIs it a good thing that the pressure difference of FFU filter element has dropped?。
Fault and alarm monitoring include overcurrent, overvoltage, undervoltage, overheating, stalling, communication abnormalities, etc. Fault information can help operators quickly locate problems.
Alarm settings should have clear thresholds and levels. General alarms can be recorded and prompted, and serious alarms can trigger shutdown or linkage. Alarm records should be saved for subsequent analysis.
The communication status reflects whether the connection between the group control system and FFU is normal. Communication status includes online, offline, communication error, etc. Communication status and operating status should be displayed separately to avoid confusion.
If multiple devices are offline at the same time, there may be a bus or controller issue. If a single unit is offline, there may be a problem with the device's address, wiring, or controller.
Monitoring data can be recorded and saved. The recorded content includes time, equipment address, operating status, rotation speed or air volume, pressure difference, fault and communication status. Records can be saved at time intervals for easy observation of trends.
Trend data can help determine filter life, equipment status and regional operational stability.
Monitoring items should be selected based on project needs. Basic items can include operating status, speed and communication status. Extensions can include air volume, differential pressure and fault alarms. For key areas, wind speed feedback or cleanliness monitoring linkage can be added.
Monitoring items should match the group control system capabilities and controller functions. For details, please refer toFFU/EFU group control touch screen controller andFFU computer group control system understands the control scheme.
In the monitoring function planning stage of the FFU centralized control system, it is recommended to confirm the following with the FFU manufacturer and designer: list of monitoring items; speed or air volume feedback method; pressure difference monitoring requirements; fault and alarm settings; communication status display; data recording and storage; trend analysis requirements; and alarm processing procedures.
If you are planning an FFU centralized control system, you can visitAili Industrial FFU fan filter unit to learn about the complete machine configuration, you can also refer toFFU/EFU group control touch screen controller andFFU computer group control system to learn about the control scheme, or contact Aili Industry for monitoring scheme support.
FFU centralized control systems usually need to monitor operating status, rotation speed or air volume, filter pressure difference, fault alarm and communication status. Monitoring items should correspond to operation management and maintenance needs, and cannot only record rotational speed. Monitoring data and trends can help schedule maintenance and determine system status.
