3.07 CONTROLS CONFIGURATION

A. MASTER BLOWER PROGRAMMING AND CONFIGURATION. There are two groups of blowers, West Blowers and East Blowers that shall operate independently of each other. Each group of blowers will be coordinated by separate master blower control functionality. Master control functionality is defined in more detail below. The Blower Suppler shall be responsible for developing master control functionality code and providing that code to the Owner for implementation in the Area PLC. The Blower supplier shall be responsible for developing a detailed test plan to ensure all the functionality defined within this document and all standard functionality provided with each blower operates as intended to maintain the safe and efficient operation of all the blowers at each location. The Blower Supplier shall have a representative with a minimum of two (2) years’ aeration control experience in the field during startup and commissioning to validate each aspect of the master blower functionality and all standard functionality provided with each blower using detail test plans and forms to document that validation. The Master Blower functionality for each group of blowers shall reside in a single Contractor furnished and installed Area PLC. The Owner will be responsible for programming the Area PLC to perform functions outside the scope of the Blower Supplier and loading Blower Supplier programs into the Area PLC to accomplish the master blower control functionality. The Area PLC will be integrated into an existing Emerson Ovation Distributed Control System (DCS) by the Owner; therefore, all remote control interfaces including set points, indications, trending, and alarming will be Owner integrated. The Blower Supplier shall provide all coordination necessary for complete integration with the DCS.

1. Master Blower Control Functionality. In addition to the control and operation of each individual blower with all standard and none standard functionality, the Blower

3/15/18 CAB Project 43 11 15 - 36

Supplier shall provide Master Blower control functionality for each group of blowers East Blowers and West Blowers. The minimum functionality shall include the following. a) Lead/Lag/Standby Operation. The Blower Supplier shall be responsible for

developing code that allows the Operator to select the lead, lag, and standby operation of each group of blowers separately. The logic must accommodate all combinations of blower lead, lag, and standby assignments. When the blowers are operating in a remote control (not local control) the blowers will be started and stopped based on the capacity needs of the system and the best achievable energy efficiency. When the overall capacity of a give system calls for one blower to efficiently deliver the required air then the system will start the Lead blower. Subsequent lag blowers shall be started in the most energy efficient way possible to provide increase capacity demand for air. Lag blowers shall be stopped in the most energy efficient way possible when demand for air decreases overall capacity required. Hysteresis shall be provided between the start and stop of lag blowers to prevent repeated and rapid starts and stops. If the operator changes the lead- lag sequence, the blowers will immediately start and stop as needed to accommodate the change. This functionality shall be validated by the Engineer, Blower Supplier, and Owner during final startup and commissioning.

b) Header Pressure Control. The Blower Supplier shall be responsible for developing code that allows the Operator to control the header pressure while running all blowers at the same speed for each group of blowers. Pressure shall be controlled by a Proportional-Integral-Derivative (PID) controller. Logic shall be included to ramp up starting blowers and ramp down stopping blowers with long enough ramp times to allow the PID controller to react the change in the number of blowers operating. Logic shall be designed to maintain highest energy efficiency possible. This functionality shall be validated by the Engineer, Blower Supplier, and Owner during final startup and commissioning.

c) Combined Flow Control. The Blower Supplier shall be responsible for developing code that allows the Operator to control the overall air flow. The logic shall divide up a single flow set point and send it to the appropriate number of blowers to achieve the flow capacity in the most energy efficient way. This functionality shall be validated by the Engineer, Blower Supplier, and Owner during final startup and commissioning.

B. PLC ARRANGEMENT AND CONFIGURATION. The PLC shall be configured to perform all control functionality defined in this specification and shall be configured to interface with the District’s PCCS. The PCCS will be configured by District; however, the Contractor shall design and configure the controls to allow the District to perform remote monitoring from the PCCS. To ensure coordination of controls the Contractor shall attend two (2) control integration workshops with the District for coordinating the controls and with the District PCCS system.

3/15/18 CAB Project 43 11 15 - 37

C. INDUSTRIAL ETHERNET SWITCH CONFIGURATION. The configuration settings of the Ethernet switches shall be coordinated with the District’s control system network which will be provided at the workshop. The Contractor shall be required to attend two (2) workshops with the District to ensure that the switches are configured for seamless integration into the overall network schema. All aspects of the network configuration shall be documented and agreed upon at the workshops. Topics discussed at the workshops shall include but is not limited to virtual local area networks, quality of service, and internet protocol addressing for all equipment. The Contractor shall bring an experienced network programmer to the workshop for the discussion where they will be prepared to present their resume. If the Construction Manager or the District determine that the Contractor’s network configuration personnel is not qualified the workshop obligations shall not be meet and the Contractor shall reschedule the workshop. All network configuration files shall be turned over to the District for review upon request at any time during the configuration of the Ethernet Switches. Final documentation of the configuration shall be submitted in the O&M manual.

D. CONFIGURATION WORKSHOPS, MEETINGS, AND REQUIREMENTS. The Blower Supplier, Owner, and PMO shall attend and/or conduct configuration and programming coordination workshops.
