Check wiring schematic (sections 4 and 5)
- Ensure correct pinout for pressuriser and controller
Ensure correct voltage (12V or 24V) to the pressuriser motor pin A (red wire)
Ensure continuity to earth from motor pin B (black wire)
Ensure signal voltage (1.6V – 10V) to pressuriser motor pin C (yellow wire)
Test motor by powering Pin A & C simultaneously

1.2 Pressuriser noisy / running at full speed

Check filter condition
Check filter securely fitted
Check doors and windows are closing properly
Check cabin sealing (250+ Pa requirement for system max speed test)
