The 30-second delay is a characteristic of which chip detector?

• A. Main module chip detector
• B. All transmission chip detectors
• C. Primary chip detector
• D. Backup chip detector

Answer: (A)

The 30-second delay is built into the main module chip detector to avoid false alarms and ensure a real contamination signal is present before warning you. In the UH-60S transmission system, chip detectors monitor for metal particles in the gear/gearbox area. If a detector sees metal, the system doesn’t immediately trip a warning; it waits about 30 seconds to let transient shedding (like from startup, shutdown, or brief load changes) clear or to confirm the contamination persists. This delay helps distinguish a genuine fault from a temporary condition. Backup detectors or other transmission chip detectors don’t share this same 30-second timing behavior, so the characteristic delay described here points specifically to the main module chip detector.
