C-2 SYSTEM FUNCTIONAL AND TECHNICAL SPECIFICATIONS

C-2.1 GENERAL

The work covered by this section consists of furnishing all plant, labor and material to install submersible pressure transducer water level sensors (3), stilling wells, support frames, electrical enclosures, conduit, and wiring along with the reprogramming of the Programmable Logic Controllers (PLC), and all accessories necessary to provide needed input and output to monitor and control 6 tainter gates. The PLC controls are located inside the Gate Control House. All equipment provided shall be standard products of a manufacturer regularly engaged in the manufacturing of such products, which are of a similar material, design and workmanship.

The Programmable Logic Controller (PLC) system, as defined in NEMA IA 2 and NEMA ICS 1, shall control gate functions as necessary for automatic, Semi- Automatic and Local Manual mode. The PLC system shall be capable of starting and stopping the various gate motors and other functions as specified herein and shown on the drawings. Unless otherwise noted herein, all equipment covered under this specification shall be installed in accordance with Section C. The Contractor shall use the existing PLC but reprogram it to meet contract requirements. Major items of service are as listed below:

(1) Furnish and install water level transducers which shall include, but not be limited to: the submersible pressure transducer water level sensor, stilling tube, conduit, support frame and wiring. All wiring from the sensors to the Control House shall run underground encased in conduit. The Contractor shall tie new conduit into the existing conduit exiting the building.

(2) Reprogramming of the PLC system. The System shall be programmed to provide all functionality as specified herein or as shown on the contract drawings.

(3) Remove the existing ultrasonic water level sensors (3) to include all wiring. Sensors shall become the property of the Contractor. All mounting brackets and underground conduit, not used, shall be abandoned in-place.

(4) The bubbler system output shall be removed from the PLC input but the bubbler system and compressor shall remain as a stand-alone visual check for water levels.

C-2.1.1 SYSTEM DESCRIPTION

The control systems supplied under these specifications consist of one system to be furnished and installed at Big Lake North End and Diversion Channel Structure. The system will be installed at the North End and Diversion Channel Control Structures and will include all components necessary to measure and transmit the water level elevations from three (3) different sites. At the location there is an existing enclosure containing all motor-controller components and an existing enclosure containing all the bubbler system components. The bubbler system shall remain as a stand-alone unit but shall be disconnected from the control scheme.

The layout of the existing underground conduit is shown on the drawings in APPENDIX A.

C-2.1.1.1 CONTROL SYSTEM FOR NORTH END AND DIVERSION CHANNEL

The existing PLC Control System was installed in 2015 consists of the following:

(1) A Mirologix 1400, Model 1766-L32 AWA) small Programmable Logic Controller (PLC) manufactured by Allen Bradley.

(2) A Panel View Plus 6, Model 700 machine level Human Machine Interface (HMI) manufactured by Rockwell Automation.

(3) A Single Phase, 240W, 24V, 10A Power Supply (model S8VK-G) manufactured by

OMRON

Equipment furnished under this contract will consist of three (3) submersible pressure transducer water level sensors (one upstream of the diversion structure, one downstream of the diversion structure and one downstream of the north end structure). The PLC will control the 6 motor-operated gates. The gates on the control structure are designated Gates North End 1, 2, 3 and Gates Diversion Channel 1, 2, 3. The PLC shall be programmed to never allow more than one of three gates of the North Structure and one of the three gates of the Diversion Channel to operate at any time. The existing three bubbler tubes sense water level in three places. The tube outlet is located at EL 230.8 and provides a 4-20 mA analog signal to the existing PLC. Currently, the water level at each of the three monitoring sites is read by an ultrasonic sensor shooting a signal off the water surface. This system has proven unreliable due to wave action and trash accumulation. These sensors will be replaced with submerged water level sensors. Sensor 1 will determine the water level upstream of the two structures.

Sensor 2 will determine the downstream water level of the Diversion Channel Structure.

Sensor 3 will determine the downstream water level of the North End Structure.

The PLC will have two modes to control both the North End and the Diversion Channel structures. The modes will be Normal and Season 1 (Water Fowl Season). Each Seasonal mode will be a separate screen on the HMI and will have a button to turn the mode on and off, a changeable low set point and a changeable high set point. See Table below for set points and operation modes for both the North End and the Diversion Channel.

Note 1:

The Diversion Channel will start opening when the water level is above the seasonal set point and the North End gates (3) are completely closed.

Opening Sequence for both structures will be conducted in 1-FT increments for each gate.

Begin with the middle gate (Gate 2). Initiate the raising of the gate by 1-FT. Forty five seconds after the opening of Gate 2 finishes, initiate 1-FT opening of the outside Gate 1. Forty five seconds after the opening of Gate 1 finishes, initiate the opening of Gate 3.

Closing sequence for both structures will be opposite of the opening sequence. The PLC will check the water level then close the outside gate (Gate 3). Wait 45 seconds after gate 3 closes 1- Foot; then close the other outside gate (Gate 1), Wait 45 seconds after gate 1 closes 1-foot , and then close the middle gate (Gate 2).

Gate upper and lower limits for both structures (Contractor to verify) should be set as follows:

Upper software Limit 10 feet (from the count of the gear)

Upper hard limit 10.5 feet (adjusted in the limit switches)

Lower software Limit 0 feet (from the count of the gear)

Lower Hard limit -0.5 feet (adjusted in the limit switches)

The HMI will display the water level and the height of each gate and controls to switch from auto to semi-auto. This display will be in the form of a graphical representation of the gated structure with controls that can be clicked on for each gate. When the operator selects the gate, the HMI will display a gate control page that s hows the position, water level, auto manual controls, gate status, motor status, and hard limits.

C-2.1.2 RE-PROGRAMMING

The PLC System Integrator shall perform all configuration and re-programming of the PLC system, including any programming necessary to test the PLC system.

PLC shall be programmed with a software feature (e.g. software selector switch) that will allow the operator to select either "Fully-Automatic" mode, "Semi-Automatic" mode or “Manual” mode of operation. In "Fully-Automatic" mode, the PLC will control the gates in response to the 4-20 mA signal supplied from the submersible pressure transducer water level system. In "Semi- Automatic" mode, the PLC will control the gates in response to a command(s) by the operator using the operator interface, Human Machine Interface (HMI) Display. Each "Raise" or "Lower" command will initiate one raise or lower gate movement sequence. In the “Manual” mode of operation, the operator can raise or lower one gate at a time and must be performed at the gate structure only.

C-2.2 STANDARD PRODUCTS

Provide materials and equipment that are products of manufacturers regularly engaged in the production of such products which are of equal material, design and workmanship. Products shall have been in satisfactory commercial or industrial use for 2 years prior to bid opening.

The Contractor Performance Assessment Reporting System (CPARS) is a web-based system used to input data on contractor performance. Once the data is input to the CPARS system, this data is then uploaded to the Past Performance Information Retrieval System (PPIRS) database and is made available for use in performance evaluations. These contractor performance assessment reports (CPARS) will be used as an aid in awarding contracts to contractors that consistently provide quality, on-time products and services that conform to contractual requirements. The CPARS system can be accessed via the Internet website https://www.cpars.gov <https://www.cpars.gov> . The Memphis District point of contact is Mr.

Del Warfield. Mr. Warfield can be contacted at Delwick.E.Warfield@usace.army.mil <mailto:Delwick.E.Warfield@usace.army.mil
