What happens when the low oil level indicator switch is triggered?

When the low oil level indicator switch is triggered, the compressor automatically shuts down. This safety mechanism is in place to prevent damage to the compressor, which could occur if it continues to operate without sufficient oil. Oil is essential for lubricating the moving parts, and operating with a low oil level can lead to increased friction and potential failure of the compressor. Therefore, the automatic shutdown protects the equipment and ensures operational safety.

While warning signals may be a feature of the system (as suggested in one of the options), the primary action taken in response to the low oil level being detected is the immediate shutdown of the compressor. This is a critical safety function designed to avoid catastrophic failures and costly repairs.
