Electronic and manual backup flow control systems

A method for selectively deploying and retracting backup manual controls for controlling the flow of fluid in a flow control system, comprising:

• latching a flow selector assembly in a retracted state via a latching pin, the flow selector assembly comprising:
• at least one mechanically operated flow control valve configured to control the flow rate of a fluid;
• and
• at least one flow selector connected to the flow selector assembly, each of the at least one flow selectors configured to actuate one of the at least one mechanically operated flow control valves to select a flow rate of a fluid through the mechanically operated flow control valve;
• receiving an instruction to enter a manual mode in response to detecting an error in an electronic mode;
• and
• deploying the flow selector assembly by translating the flow selector assembly relative to a mounting plate.
