A sequencer helps in which of the following processes?

A sequencer plays a crucial role in preventing electrical overload within heating systems. It functions by controlling the sequence in which the heating elements or stages are activated. When a heating system has multiple heating elements, the sequencer ensures that these elements do not turn on all at once, which could lead to a surge in electrical demand and potentially overload the circuit.

By staging the activation of each heating element, the sequencer allows for a gradual ramp-up of the heating output, maintaining a balanced electrical load that aligns with the system's design and capacity. This thoughtful control helps to ensure that the system operates efficiently while protecting the electrical infrastructure from damage caused by high current loads.
