Design engineers should describe the manual equipment controls available to operators from OITs or HMI stations. Devices that are manually adjusted to control the system are identified and their function described. To assist operators in performing complex manual operations that are not easily automated, equipment-operating tables should be used to identify the correct equipment state for repeatable manual operations. These tables will assist the operator in matching the equipment state to the required actions and will primarily identify pump status, speed, and valve positions. Table 5.1 presents a sample equipment-operating table.
