What condition would cause the MX2 to de-energize once it is energized?

The condition that causes the MX2 to de-energize once it is energized is when the tank is empty. This safety feature is crucial in many systems to prevent damage and ensure proper operation. When the tank is empty, there's a risk that the pump may run dry, which can lead to overheating, cavitation in the pump, or even mechanical failure. By de-energizing the MX2 when the tank is empty, the system protects its components and prevents operational hazards.

Other situations, such as circuit overloads or high voltage, could theoretically lead to de-energization, but they are typically managed with separate protective devices or settings. Likewise, engaging the emergency stop would usually apply to human intervention rather than a condition related directly to the operational status of the tank itself. The specific focus on the tank being empty highlights the design's emphasis on maintaining both safety and equipment integrity.
