Job Requisition Number: 24141. University of California, Berkeley Building Energy Management Systems (EMS) consists of Automated Logic and Barrington Control Systems. The position of Building Automation Mechanic is responsible for the day to day operation and maintenance of both systems installed in over 100 facilities at Berkeley Campus.
Barrrington Control System was adopted at Berkeley Campus over 30 years ago as the standard Building Automation System. Barrington Systems devices and subcomponents are not in production any more. We heavily depend on our Electronic Technicians to maintain complicated electronic systems due to availability of spare parts and lack of documentation. Automated Logic is the Campus Building Automation system installed in over 30 facilities on Campus.The individual must have proven training and experience in the field of HVAC/R systems analysis, calibration, and repair. Knowledge and ability in troubleshooting electronic and pneumatic controls.
1.Construction Installation of Building EMS: Perform duties as team technician for the conversion of building energy management control systems campus wide. Assist in all aspects of planning and scheduling of various phases of EMS construction. Develop and implement sequence of operation, software programming strategies and hardware point lists for control systems. Document and install control system hardware, cabling and conduit that are necessary to facilitate building energy management conversions. This will include installing new control panels, new field devices (VAV terminal boxes, temperature sensors, pressure sensors, flow sensors, control relays, valve and damper actuators, etc) and all communication cabling between panels and devices. Maintain, troubleshoot, and install electronic systems sub-systems; analyze technical data to determine applicability to design problems. Use architectural, civil, structural mechanical, plumbing and electrical blueprints, freehand and computer generated sketches. Work with systems involving control voltage signals and power devices ranging from 2-24 VAC and DC. Perform calculations to size circuit control transformers, wire, fuses and other control circuit components. Calculate conduit fill limitations and sizes. Adapt equipment to perform new or different functions to meet objectives. Read and interpret control and ladder logic type diagrams. May serve as working leader to other electronics technicians performing related work, and assist in solving electronic problems. 2.Preventative maintenance and repair of EMS Perform preventive maintenance procedures on energy management control systems to ensure that the systems operate according to manufacturers' specifications and to system design parameters. Typical procedures include cleaning of control panel components, tightening of terminal connections, calibrating sensors, performing visual inspections and performing various types of circuit testing using common test equipment. Perform minor repairs during the process of performing the preventive maintenance procedures to ensure the integrity of the systems wiring and component installations. Respond to emergency and routine EMS service calls to perform repairs as required.
