Which accessory module has a low oil pressure switch and chip detector?

• A. Right
• B. Left
• C. Auxiliary
• D. Center

Answer: (B)

The left accessory module is where lubrication monitoring is implemented. The low oil pressure switch and the chip detector are both housed there to continuously monitor the gearbox’s lubrication state. The oil pressure switch provides a warning or shutdown signal if oil pressure drops below the safe level, protecting the gearbox from damage. The chip detector senses ferrous particles in the oil, indicating internal wear or debris that could signal a developing failure. Having both sensors in the left module ensures timely alerts for both loss of lubrication and particulate wear, which is why that module is the correct choice. Other accessory modules are dedicated to different systems and do not contain this pair of lubrication-monitoring devices.
