Control of Submersible Propellers
The operation of the diving propeller is via on-site manual control. Two PLC Automatic Control Methods.

2. Automatic Control
Please provide the Chinese content that needs to be translated into American English. In PLC automatic operation mode, the submersible propeller is automatically controlled by time. The submersible mixer operates continuously or intermittently.
When the switch is set to the fully automatic control position, the machine can operate in the following ways.
(1) Via the startup button on the control panel. (2) Through the time control on the control panel.
Field Control Box for Submersible Mixers
Field Control Cabinet for Equipment MatchingMeets all design specifications, while adhering to IEC Standard or Equivalent IEC StandardStandard; meets local climatic conditions.
Each set of dive thrusters is equipped with a local control box. The specifications for the on-site control box are as follows:
(1) In addition to the interior buttons and signal lights, 35 terminal blocks are included.
(2) Purchase a conversion transformer for motor protection, to be ordered with the equipment.
(3) The start/stop button should have two contacts, and the stop button (with a mushroom head) should remain in the pressed position.
(4) To ensure a seamless connection between the field control box and the entire factory's control system, the terminal blocks within the control box are fitted with Weidmüller products.
(5) Cable junctions included.
(6) Protection Rating: IP65.
(7) Reserve PLC interfaces, with each equipment requiring control both at the on-site control cabinet and the central control room.
(8)Field control box material, outdoor use 304 Stainless steel, carbon steel coated indoors, cabinet style and coating colorManufacturer confirmed。
(9) Components within the control box are sourced from ABB, Schneider, Siemens, or equivalent brands.
