Direct human control is essential when setting up and maintaining a system. Manual mode gives you that control, letting you directly operate actuators, jog positions, and switch sensors on and off to observe how the circuit responds. This makes it possible to calibrate thresholds, verify wiring, test interlocks, and check that each component behaves correctly without the automatic process running. It also reduces the risk of unintended actions that could occur if the program were driving the system during setup.

In contrast, automatic mode runs the programmed sequence, which can hide setup issues or cause unexpected moves while you’re trying to configure things. Semi-automatic blends some automation with manual steps, but it still isn’t as safe or straightforward for thorough setup tasks. The Emergency Stop is a safety feature to halt everything and is not a mode used for routine setup or maintenance.
