Missing Pressure Reading
Missing Pressure Reading
The pressure readings read by the pump ADC (analog-digital converter) are
missing.
The ADC reads the pressure readings from the damper every 1ms. If the
readings are missing for longer than 10 seconds, the error message is
generated.
Probable Causes • Damper not connected.
• Defective damper.
• Defective LPM board.
Suggested Actions ❏ Ensure the damper is connected, clean and seated correctly.
❏ Exchange the damper.
❏ Exchange the LPM board.
