Answer: (1) On the electrical control panel of each air compressor, turn the selection switch to the joint control cut-out state, then the unit has exited the joint control state individually, and can be operated remotely individually on the air compressor operation panel of each unit.
(2) On the electrical control panel of each air compressor, turn the selection switch to the joint control cut-in state, and on the joint control cabinet operation panel, turn the single control joint control selection switch to the single control state, then you can operate each unit individually on the joint control cabinet panel.
(3) On the electrical control panel of each air compressor, turn the selection switch to the joint control cut-in state, and on the joint control cabinet operation panel, turn the single control joint control selection switch to the joint control state, then you can perform joint control operations on the joint control cabinet panel.
(4) When switching from single control state to joint control state, the original state of each unit remains unchanged. Then, you must press the start button on the joint control cabinet operation panel to enter the joint control state.
(5) In the joint control state, if a serious fault occurs in the air compressor, the program will automatically cut the unit out of the joint control state and the air compressor will automatically stop. Then, turn the joint control knob on the air compressor electrical control panel to the cut-out state. Cut off the power supply separately and perform maintenance. After the maintenance is completed, turn on the power supply and turn the joint control knob to the cut-in state, and the unit can still automatically enter the joint control.
