Through this service we will extend equipment <br />life, reduce energy consumption, and reduce the risk of costly and disruptive <br />breakdowns. Siemenswill provide preventive maintenance in accordance with a <br />program of routines as determined by our experience, equipment application and <br />location. The list of field panels and / or devices included under this service are <br />identified in the List of Maintained Equipment in this proposal. <br />Software Analysis & Optimization: Through Software Analysis & Optimization, <br />Siemens will help ensure that the HVAC Control System is operating properly to <br />minimize any software problems that would negatively impact system performance. <br />We will address any programming errors, failed points, points in alarm, unresolved <br />points or points in operator priority, both at the front end workstation and at the field <br />panel. This will increase system efficiency, assure compliance to specified conditions, <br />and reduce the risk of costly and disruptive system problems. We will perform this <br />service using onsite visits and / or remote services (if applicable). <br />Control Loop Analysis & Optimization: Control loops by their nature drift out of <br />calibration with changes in mechanical efficiency, building use, and climatic <br />conditions. Through this service Slemens will ensure control loops for devices such <br />as valves, dampers, actuators, etc., experience minimized overshooting and <br />oscillatory behavior. You will benefit from a more comfortable and productive <br />environment and lower energy consumption through more efficient equipment <br />usage. <br />Network Analysis & Optimization: Through Network Analysis & Optimization, we <br />ensure reliable and optimized communication throughout your HVAC Control <br />System's Building Level Network of field panels. The benefit will be increased data <br />network up -time and faster problem resolution. Using SIEMENS Network <br />Performance Diagnostic Technologies, our proactive calibration and tuning of the <br />data network analyzes variables impacting network performance, including node <br />tables, token passes, and turn speed, change of values over the network, unresolved <br />points, and overall operation. <br />Siemens Industry, Inc.
