Operational Theory The P185/P260WIR machine has an electronic monitor and control system that is used to provide discharge air pressure control and manage monitor functions. The system uses the SECU controller to perform these functions. The electrical system connects all the necessary switches, sensors and transducers to the controller in order for it to perform the monitor and control functions.
Page 8
Sensors and Transducers The electronics system contains a transducer and switches that are used to monitor the compressor. Various machine temperatures are monitored using temperature switches that open when the switch exceeds its threshold. The open switch disconnects battery voltage input to the SECU controller indicating a problem.
