Start-Up Procedure For 1-Drum 3D Trasar Scale Blowdown Control - Nalco 3D TRASAR Series Installation And Operation Manual

5.2.2 Start-Up Procedure for 1-Drum 3D TRASAR Scale Blowdown Control

STEP 1 - TRASAR Control Mode
• Connect the product feed pump to TRASAR control Relay # 1.
• Connect the blowdown valve to BLOWDOWN control Relay #6.
• At the controller, activate the "System Start-up" mode (Refer to Section 4.10.1 1).
• Launch the Configurator on your laptop PC and select the configuration for this system.
• In the Configurator Alarm Settings window:
1. Click the Failsafe Relay Settings tab, set the Blowdown Valve Timeout Limit to a mini-
mum of 240 minutes (If the blowdown valve is not being controlled by the 3D TRASAR
controller, set the Blowdown Valve Timeout Limit to zero).
2. Click OK.
• In the Configurator Control Settings window:
1. Under Installed Sensors set the Conductivity Probe to Controlling.
2. Click the Blowdown/pH tab, set the Blowdown Control Method to Conductivity
Setpoint, enter the desired Blowdown Setpoint, and accept the default control range.
3. Click the Inhibitor tab, set the Number of Inhibitor Products to 1, choose the Product
Name, set the Control Method to TRASAR Control, enter the Inhibitor 1 Set Point value
recommended by the 3D TRASAR Optimizer , and accept the default control range.
4. Click OK.
• 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 for > 5 HTI's.
Note: On the controller LCD, "Product-i" reading indicates the inert TRASAR level and "Product-a"
reading indicates the active Tagged Polymer level, as ppm product.
STEP 2 - 3D TRASAR Scale Blowdown Monitoring Mode
• At the controller, determine the T agged Polymer setpoint by reading the average Tagged polymer
level over the last month of TRASAR control (see Section 4.9.5 for plot data instructions).
Note: Make sure to plot the data for the product indicated by "- a " (TAG) reading.
!STOP! The "-i" (TRASAR) reading should be greater than the "-a" (TAG) reading.
IF NOT – call 630-305-CHEM before proceeding and remain in TRASAR control.
• Change the product feed pump electrical connections to T AG POLYMER control Relay # 2.
• Leave the blowdown valve connected to BLOW DOWN control Relay # 6.
• In the Configurator Control Settings window:
1. Click the Blowdown/pH tab, set the Blowdown Control Method to 3D TRASAR Scale
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. Click the Inhibitor tab, change the Product Control Method to Tagged Polymer Control,
enter the last month average Tagged Polymer level as the Inhibitor 1 Set Point, and accept
the default control range.
• Do NOT change any other settings.
