Potential Root Cause
1. The pressure volume is too large,
reduce the volume and try again.
2. The leakage of pressure volume is too
large. Test the leakage and try again.
3. Ambient pressure is lower than the
negative gauge setpoint. Change the
negative gauge setpoint to a reasonable
value at current ambient pressure.
4. The unit needs service.
Try to configure a valid value.
