1.2 Interpretation on the schematic diagram

◆ 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.
◆ 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.
◆ 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.
