Pellet Feeder Operation - Nalco 3D TRASAR Series Installation And Operation Manual

6.4 3D TRASAR Bio-Control/3D TRASAR Bio-Shock Start-Up
Procedure (con't)
• Any further question regarding the relay wiring and setup, please contact 3D TRASAR
Support or NGES Help Desk.
NOTE: Verify oxidant residual is below 0.1 ppm TRH before proceeding any further! Use
!
DPD Total Colorimetric Test
STEP 3 - Using the Configurator , set up the controller for 3D TRASAR Bio-Control or 3D TRASAR
Bio-Shock mode.
In the System Information window, enter the system volume (system volume needs to be
•
as accurate as possible).
In the Control Settings window, set the oxidizing biocide control method to "3D TRASAR
•
Bio-Control" or "3D TRASAR Bio-Shock Mode".
If using scheduled Ox slugs with 3D TRASAR Bio-Control or 3D TRASAR Bio-Shock
•
mode, set up the slug parameters (prebleed, feed, post feed and recovery) in the Ox slug
window.
If using Ox slugs or 3D TRASAR Bio-Shock mode, make sure the ORP probe is clean and
•
calibrated.
Select the desired bio-reporter and indicate if the oxidant feed pump is optimally sized,
•
oversized or undersized for the system.
In the Alarm Settings window, select the appropriate Alarm Pump Duty for the oxidizing
•
biocide (see Section 4.5.4).
Upload the modified configuration to the controller .
•
Check to make sure the Configurator program asked for a 'Reinitialization or Reboot' of
•
the Controller. If not, either power cycle the Controller using the on/off switch or Reboot
from Configurator program.
STEP 4 - If using a pellet feeder and the system volume exceeds 160,000 gal, deliver the required
number of bio-reporter Quick Dose Pouches to the cooling system (see Section 6.7).

Pellet Feeder Operation

The 3D TRASAR Pellet Feeder automatically feeds pelletized bio-reporter to the cooling system at
predetermined intervals and dosages (# of pellets) as directed by the 3D TRASAR controller .
The feeder consists of a chemical hopper to hold the pelletized product, a motorized ball valve and
feeder neck assembly. This is connected to a piping assembly containing a y-strainer designed to
trap the fed pellets in a flowing water stream where they quickly dissolve into the circulating water .
When a pellet is to be fed, a signal from the controller initiates the process. The feeder assembly at
the bottom of the hopper, not unlike that in a "gumball" machine, rotates and traps a pellet, drops it
down into the feeder tube past an LED that 'counts' t he pellet, and into the ball valve assembly
which then rotates to drop the pellet into the flowing water stream.
