5500 - Installation & Operation Manual
5.3.2 Start-up Procedure for 2-Drum 3D TRASAR Scale Tagged Polymer Control
(con’t)
• Upload the new configuration to the 3D TRASAR controller.
• The Configurator program should request an automatic “REBOOT” of the controller.
If not – reboot manually either by using the power switch or through the Configurator: go to “Con-
troller” —> “Tools” —> “Reboot Controller”.
• Operate the cooling system under TRASAR Control and slaved Tagged Polymer Control for
approximately 5 HTI’s. The Tagged Polymer product level should reach steady state after 5 HTI’s,
while any old untagged polymer will be reduced to zero.
• Once the Tagged Polymer product level reaches steady state move to Step 2.
NOTE
: If the steady state Tagged polymer product level needs to be achieved in a shorter
period of time, it is OK to slug feed the product. It is still necessary to run for approxi-
mately 5 HTI’s to replace untagged polymer with Tagged polymer.

STEP 2 - 3D TRASAR Scale Tagged Polymer Monitoring Mode
•
In the Configurator
Control Settings
window:
1. Click the
Inhibitor
tab, leave the TRASAR
Control Method
to
TRASAR Control
.
2. Under
3D TRASAR Scale Control Settings
, check the
Monitor Only (Setpoint does not
change)
box. By checking this box, no blowdown setpoint adjustments will be made.
3. Change the Tagged Polymer
Product Control Method
to
Scale Index Control
, enter the
Tagged Polymer
Set Point
as recommended by the 3D TRASAR Optimizer, and accept the
default control range.
4. Leave the TRASAR product
Pumping Rate
and the TAG Polymer product
Pumping Rate
the same as entered in Step 1.
• Upload the new configuration to the 3D TRASAR controller.
• The Configurator program should request an automatic “REBOOT” of the controller.
If not – reboot manually either by using the power switch or through the Configurator: go to “Con-
troller” —> “Tools” —> “Reboot Controller”.
• After the controller reboots – go to the Configurator
Control Settings
window, under the
Inhibitor
tab, click the “
RELEARN NOW
” button to perform a Relearn. This will clear the memory of
learned scaling stresses and start the new Learning Period.
• The number of cycles for the “Learning Period” is automatically calculated and varies based on the
user input
HTI.
• The system is now in
3D TRASAR Scale Tagged Polymer Monitoring Mode
.
Note
: The Tagged
Polymer set point will NOT be adjusted based on NSI until Step 3.
Note
: The controller LCD will show dashes (- - -) for NSI, and the data log will show a value of
–999
for NSI until the required “Learning Period” is completed. The “Learning Period” will last between 7
to 8 HTI’s if the system HTI is < 72 hours, and 22 days if the HTI is > 72 hours. The “Learning
Period” is over when NSI values start to appear.
