Architect – A person who knows a very little about a great deal and keeps
knowing less and less about more and more until he knows practically nothing
about everything.
Engineer – A person who knows a great deal about a very little and who goes
along knowing more and more about less and less until he knows practically
everything about nothing.
Contractor – A person who starts out knowing practically everything about
everything but ends up knowing nothing about anything due to his association
with Architects and Engineers

22. Eagle River SCADA Functional Narrative
DATE / TIME: 9/24/2010 – Revised = 8/31/2011
PROGRAMMER: Yet to be determined.
EQUIPMENT: Soda Ash Feed System – project #00000004837
INTENDED FUNCTION: The Control of the Soda Ash System locally from Panel view
and remotely from SCADA terminals.
1. Local control for mix and feeding of solution.
2. Touch screen interface will allow control in auto and manual of system
2 T h i t f ill ll t l i t d l f t
components including: Mixing system, Transfer Pumps, and Feed Pumps.
3. Prefer AB 1250 Panelview touch screen HMI.
4. Remote SCADA control from the “Control Room” will be needed for chemical feed
pump speed in % speed and/or dosage in mg/L, but not mixing functions.
Mixing only needs local control.
5. Solution Feed Pump Control from the control room should be Auto/Off, not Hand.
Setpoint Screen
Feed Pump control can be done in a similar fashion to the virtual control panels found
in our Set point screen for existing chemical feed equipment.
The feed control function requires a flow input and some programming calculations to
generate proper control functions. Graphic control faceplate should show the following:
Dosage Setpoint in mg/L (operator setpoint)
Actual Dosage in mg/L (target vs actual)
pH setpoint in SU (operator setpoint)
Actual pH – (from bld 3 instrument input)
Pounds of soda ash per batch/tank (operator entered)
Max feed rate in gal/hr (operator entered)
Min feed rate in gal/hr (operator entered)
Solution Strength in % by wt (Calculated by scada from pounds of soda ash and tank
size)
Output Gal/Hr – process variable (output signal)
Feed Tank Level – in inches and Gallons (from tank level instrument)
Buttons on Control faceplate – Manual (%), Dosage Mode, pH Mode, Off. Similar to
existing setup for Sodium Hypochlorite. % feed setpoint pops up when Manual is
activated.

23. Soda Ash System Screen – Graphical display of system
Since this system is to be located in the RAS Room, there will need to be some
y ,
modification to the existing RAS Room graphic.
Relocation of the Sample Pump icons will give space for a soda ash mixing system
graphic.
A separate popup to show all the equipment in the system will be required.
p p p p q p y q
An attachment will be distributed with this document showing proposed equipment
configuration (as well as P&ID) that can be used to develop a system graphic.
Data needed on the screen is as follows:
1.
1 Lbs of Soda Ash per batch (dry) - % concentration of solution as well.
well
2. Red/Green bullet indicators for equipment on or off. – like other equipment in
our system
3. Indication of state only needed for dry feed auger, mixers, etc.
4. % speed of feed pumps – process variable.
5.
5 Tank Levels need to be shown in inches and gallons.
gallons
Control is needed on the screen as follows:
1. Pump popup faceplate with H/O/A and Pump % speed input for Hand mode.
Include the same faceplate as in setpoint screen for this system.
p p y
Historian Data to collect - will be reported in WIMS.
1. Lbs of soda ash used/day
2. The gallons of Solution Fed Each day.
3. Dose of Soda Ash Fed – Average for day at each injection point – based on pump
RPM, Concentration of solution, and flows for each injection point. RAS Dosage, and
Final Effluent Dosage.

24. Alarms in SCADA – (Supplier will provide alarm list of available alarms,
sometime)
1. Low Effluent pH
2. Low Soda Ash Solution Feed Tank Level
3. Soda Ash Solution Feed Pump Failure
4. Soda Ash Mix System Failure
5. Dry Soda Ash Hopper Level Low.
6. SAS Dosage Low
7. SAS Batch Tank Low Level, if available.
,
System Testing Plan – (Once the factory representative is ready to complete
the startup testing)
1. Confirm all available alarms – locally and in SCADA
2. Run each system component in local hand to confirm proper operation.
3. Test Dry Feed Batching equipment – weigh amount of soda ash per batch at
different settings to confirm proper calibration.
4.
4 Run system batching of solution in Auto mode – confirm all component functions
functions.
5. Confirm proper Mix and Auto transfer of solution into feed tank.
6. Check pumping rate of feed pumps in manual and auto mode – confirm they are
consistent between pumps and modes of operation.
7.
7 Confirm dosing of soda ash solution through SCADA control.
control
8. Test flow proportional adjusting of dosing rate of feed pumps.

25. Trends in SCADA
1. Feed Rate in Gal/Hr
2. pH of Filter Effluent
3. Dosage in mg/l
4. Feed Rate in #’s per day of dry Soda Ash.
Startup Commissioning Checklist
□ Confirm all available alarms – locally and in SCADA (check priority)
□ Run each system component in local hand to confirm proper operation.
□ Test Dry Feed Batching equipment – weigh amount of soda ash per batch at
different settings to confirm proper calibration.
□ Run system batching of solution in Auto mode – confirm all component functions.
□ Confirm proper Mix and Auto transfer of solution into feed tank.
□ Check pumping rate of feed pumps in manual and auto mode.
□ Confirm dosing of soda ash solution through SCADA control.
□ Test flow proportional adjusting of dosing rate of feed pumps.
□ Confirm SCADA display graphics, control functions, trending, and alarm reporting
is functional and accurate.
