1.1 Schematic Diagram of Units’ Control
(1) Interpretation on the schematic diagram
1) High pressure switch is used to identify system’s high and low pressure. When
pressure is too high, the switch will break off and send a signal to main board. Main
board will pass this signal to controller, where the error will be displayed, and stop
unit from working.
2) High/low pressure sensor is used to test unit’s high/low pressure and send real-time
data to controller, which will control each unit’s output according to the control logic.
3) Temperature sensors are used to test the tube temperature of the unit and send data
to the controller, which will control each unit’s output according to the control logic.
