Through this service we will extend equipment <br /> life, reduce energy consumption, and reduce the risk of costly and disruptive <br /> breakdowns, Siemens will 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 Siemens 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.
