Dear student,

Manual control substitutes the facility operator for the automatic control system in the feedback
loop, and leads to the risk of system or equipment mis-operation due to human error. Safety interlocks,
such as motor overload, high-high pressure switches, fire detection, etc. should therefore be hard-wired
into the control circuit such that they are active in both manual and automatic control modes. Switchgear
protective relaying required for fault protection should always be hard-wired in the circuit breaker trip
circuit and not dependent upon the controller.
