3D TRASAR
5500 - Installation & Operation Manual
15. How long does it take to complete the Learning Period?
It depends on Learning Cycles or the number of product decay cycles in the Learning Period.
• If HTI < = 72 hours: The Learning Period consists of 50 decay cycles and will take approximately 7
to 8 HTI's to complete.
• If HTI > 72 hours: The number of Learning Cycles will be less and it will take approximately 22
days to complete the Learning Period.
16. How do I know if I have completed the Learning Period?
• Check the 3D TRASAR controller display.
Press
Information
key, select
System Performance
. If a numerical value appears after Nalco
Scale Index, the learning period has completed. If "------" appears, the system is still in Learning
Mode.
Note
: After a Power Reset, the LCD also shows "-----" for NSI. NSI will be re-displayed at the end
of the first cycle after a Power Reset if the Learning Period has been completed.
• Check 3D Scale Data File, Column under "NSI Cycle."
Download 3D Scale Data File through the configurator. If numerical values other than -999 appear
in the NSI log, the learning period has completed. If -999 appears, the system is still in Learning
Mode.
17. 3D TRASAR Scale Control has been operational for a while. Why is there no NSI
value appearing on the 3D TRASAR controller display?
• 3D TRASAR Scale Control may still be in the Learning Period.
-After a Power Cycle, both the Polymer Consumption and NSI will display as "-----".
-After a Power Cycle, the Polymer consumption reading will be redisplayed at the end of the
next cycle whether or not the Learning Period has been completed.
-After a Power Cycle, the NSI reading will be redisplayed at the end of the next cycle only if
the Learning Period has been completed.
18. The LCD was showing polymer consumption. Why is it now showing "-----" on
LCD?
• After a Power Cycle, the Polymer Consumption (and NSI) will display as "-----". The Polymer
Consumption reading will be redisplayed at the end of next cycle.
• If you just performed a Relearn, during the very first cycle the polymer consumption will be dis-
played as "-----". The polymer consumption will be displayed/recorded at the end of each cycle.
