Subject: upstream cascaded controller gen. Ammonia Plant20.3 Special Considerations The Auto/Man station mode is not accessible by the operator, it can only be set through the Pump Selector Switch 10-HS-12800There should be only two operable modes: Manual and Cascade. When in Manual the operator may change its output value. When in cascade the operator will not have any access, the setpoint will be set by the **upstream cascaded controller** расположенный выше в каскадной схеме управления? Благодарю.
