With time, pressure and temperature gauges need to be recalibrated to maintain accuracy. Microprocessor controls make this maintenance requirement less costly and time-consuming. Since the development of microprocessors, the door has opened to allow plant operators easier methods to manage predictive maintenance programs. First came the control system. The control system allows operators to connect the microprocessors of multiple compressors, dryers, and other accessories to a common controller.
Many systems can accommodate up to eight air compressors to work as a system.
When compressor units experience shutdowns, it can be difficult to pinpoint the cause because several alarms may have been activated. Microprocessor control systems can monitor multiple alarms, and if shutdown occurs, recall the alarms to help identify the various problems. Also, the microprocessor control system helps operators troubleshoot through its monitoring alarm system. Even if a warning alarm is activated when the compressor is unattended, and the system corrects itself, the alarm will remain in the microprocessor panel memory, with various operating parameters that were present at the moment of the alarm. This enables operators to reconstruct and evaluate the conditions when the warning alarm was activated.
