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.
