New York City 26th Ward

Project Description:

The integrated system for control of the Polymer Make Down System consists of an EG Controls Manual Control Panel, an Automated Control Panel, and a remote touch screen located within the control room. The system interfaces with 7 batch vessels, 7 mixers, 21 valves, 4 polymer transfer pumps, and 7 level transmitters.

  • The manual panel consists of level indicators for each of the vessels, an HOA for each valve and each mixer, and status lights to indicate valve position and motor run status. The manual panel is the automatic control system backup and will be operational in the event of an automated control panel failure.
  • The automated panel includes a PLC and a color touch screen for the display of system information and access to numerous system setup parameters.
  • The remote touch screen within the control room displays the same information as the automated panel and allows the same access to system parameters as the touch screen on the automated panel.

  • The remote touch screen displays duplicate screens that are resident on the 2 local panels.
  • The remote touch screen in the control room allows the same access to system parameters as the touch screens on the automated panels.

Zelienople, PA

Project Description:

The integrated system for control at Western Butler consists of an EG Controls System Control Panel which interfaces with 3 variable speed pumps. The EG Controls System Control Panel provides both automated and manual control for the Station.

  • The System Control Panel includes Pilot Lights for status indications and alarm indications, push buttons for alarm reset, and selector switches and rheostats for manual control. A touch screen operator interface provides the operator with process information and allows for setup parameters to be entered and displayed.
  • Pumps are started and stopped automatically based on wet well level.

Greenfield Township, PA

Project Description:

The Greenfield Township system is an integrated SCADA application for monitoring and control for production wells and ground storage tanks. The total system consists of four major sets of controls:

  • Host System with the host computer, operator interface, printer and modem.
  • Main Panel with production well controls, booster pump controls, flow monitoring and chlorine pump controls.
  • Walter Business Park Tank RTU for tank monitoring.
  • Ward Industrial Park Tank RTU for tank monitoring.

Each station received a site specific controller and custom software. The Main Panel and the two tank monitoring sites have an RTU and radio equipment for remote monitoring and control. The SCADA host can monitor all sites. The Production Wells and Booster Pumps can be operated locally at the Main Panel by operator pilot devices, via the touch screen or remotely from the SCADA host.

City of Baytown, TX & City of Dayton, OH

Project Description:

Both the City of Dayton (Ohio) and the City of Baytown (Texas) are in the process of upgrading their existing pump stations with EG equipment. The Digi-Gage microprocessor controller product line has been selected in both cases due to its versatility and ease of use. Each station was custom designed to meet specific size and power requirements. The municipalities require some type of standard control methodology so that data can be sent to a central monitoring station. Costs were also controlled by using one baseline control system which could be modified by changing the Digi-Gage model and other components, as needed.
