BALANCE DAILY DETAIL STATUS CODES
Question
When and why do the status codes appear? (see example below.)
Explanation
Balance Systems - Hose W,F,G,N Results
Next to each hose collection daily average A/L result there is an assessment. The absence of any of the results
listed above indicates a pass. If any of the listed conditions W,G or F exist, they will post before a pass. The
assessment can indicate the result for one of two tests called Statistical Test or Flow Performance Test.
• W - Warning for Statistical (BLKD).
- Indicates a statistical warning if BLKD appears instead of the A/L value.
- Indicates a Flow Collect warning if the A/L value appears next to it.
- Warning for Flow Performance Test and will appear with A/L value.
- A Flow Collect warning will convert to a failure and shutdown on the 2nd day.
• F - Statistical Failure - A BLKD is posted instead of an A/L value.
- Automobiles equipped with ORVR equipment appear as a blocked dispensing event (A/L very low). ISD
separates out this type of activity from blockages that are caused by something other than ORVR vehicles. It
does this statistically using multiple dispensing events. When there are more blockages than would be
expected from normal ORVR traffic, a BLKD warning is issued.
• G - Failure for Flow Performance Test and will appear with A/L value.
• N - No Test.
