ARC-16 POWER TRIM SCRIPT Chapter 2

[mr_elbows]

As Val Kilmer said in 'Tombstone' : 'Well, that was certainly a bust'I failed to notice that the script contained a 'Loop Until' commandwhich, once started, continued in spite of the 'run between' decision being 'false'; at sunset, the 'daytime power trim' continued to attempt to raise power back to day valuethe solution was to eliminate the 'loop until' and issue a SINGLE 'raise or 'lower' command in this scriptthen schedule it to run every 2 minutesthis results in a longer time to correct power fluctuations, but a side benefit as outlined below:at power change (example day to night)it takes considerable time (90-120 seconds) for the 'power output' sample from the Gates Five to settle to its new valuethis caused the script to adjust down-down-down-down resulting in overshoot to about 900 watts before it would then go into 'raise-raise-raise' mode, then yo-yo back and forth before hitting a happy mediumthe longer time it takes is actually a benefit in this regard, new version below++++++++++++++++++'Connect to the ARC; if it can not connect, abort the scriptIf Not IsConnected(WIZ_ARC) Then If Connect(WIZ_ARC) <> "Connected" Then Message "Unable to connect to " & WIZ_ARC & ".
