8736 Instrument Control Mechanic II


TITLE Instrument Control Mechanic II




IMMEDIATE SUPERVISOR Mechanical/Electrical Maintenance Foreman

MAJOR ADMINISTRATOR Superintendent of Building and Equipment Maintenance


The Instrument Control Mechanic II provides highly skilled technical support, program analysis, and programming for the campus microprocessor-based HVAC systems. Responsibilities include installation and commissioning of new hardware points in existing microprocessor control devises, alarm analysis and follow-up, troubleshooting hardware problems within the Metasys network, and replacement of faulty components and devices. The Instrument Control Mechanic II uses operator workstations, terminals, local LED display monitors, and computers to monitor the network and adjust set points as needed. The Instrument Control Mechanic II programs and supports non-Metasys microprocessor-based control systems and devices, such as variable speed drives, self-contained environmental systems, chiller controls, and other systems which interface with Metasys. The Instrument Control Mechanic II monitors, repairs, and recalibrates the pneumatic systems controlling various processes. The Instrument Control Mechanic II performs complex technical work, on a journeyman level, in the installation, operation, maintenance, modification, overhaul, service and repair of sophisticated automatic electronic, electrical, and pneumatic control systems equipment that operate heating, ventilation, air conditioning, fire protection, and other utility and environmental control systems. The Instrument Control Mechanic inspects and tests systems to locate and diagnose faults and malfunctions, performs required repairs through replacement of inoperative parts or adjustment of thermostatic controls and blowers, and provides an estimate of repair (and/or replacement) costs.


Education: A high school diploma or the equivalent is required. Completion of a formal technical training program within the field of electronics and/or automatic electronic, electrical, and pneumatic control systems or an equivalent combination of education and experience from which comparable knowledge, skills, and abilities can be acquired, is required.

Experience: Six years of experience in the maintenance and repair of control systems and electronic apparatus is required.

Skills: A working knowledge of microprocessor-based distribution control systems, analog controls, and pneumatic controls is required. The ability to interpret wiring diagrams, blueprints, and electrical schematics is required. The ability to use test equipment and small hand and power tools, such as drills, oxygen-acetylene torches, volt-ohmmeters, circuit testers, and manifold gauges, is required. The ability to complete mathematical computations, such as addition, subtraction, multiplication, division, ratios, percentages, ranges, scaling, and graphing is required. Journeyman level skills are required in maintenance and repair procedures, including preventive maintenance, breakdown repair, and trouble-shooting, installation and fabrication techniques. The ability to develop knowledge of, respect for, and skills to engage with those of other cultures or backgrounds is required. A working knowledge of JCI GPL, GX-9100, and HVACPRO, BASIC, Visual BASIC, and LCP Graphic Configuration Language is preferred.

Effort: Near-visual acuity, depth perception, field of vision, and color vision are required in order to make electrical connections, solder and splice electrical wiring. Must be able to lift and transport materials and equipment weighing up to 50 pounds on a frequent basis and up to 100 pounds on an occasional basis; prolonged standing and frequent bending, stooping, and reaching on a daily basis; and working in confined spaces. Requires a full range of physical motion in order to operate manual and electrically-powered tools and electrical test equipment, to move throughout campus, including climbing stairs in all University buildings, and to work at heights. Work is performed indoors and out-of-doors, occasionally in environments that are dusty, noisy, or which could have work hazards. Some positions in this job classification (job title) are designated as essential employees who must report to work as scheduled when University offices are closed due to severe weather; the supervisor will communicate whether the particular position is considered essential and under what situations.

Other: Scope of the position requires exposure to and use of chemicals, solvents, and cleaners common to mechanical work that may be hazardous and/or cause injury if specific instructions regarding their mixture, use, and disposal/storage are not properly followed.


1. Performs highly skilled technical support of pneumatic and microprocessor, pneumatic, analog, and electro-hydraulic control devices by installing, commissioning, maintaining, repairing, and replacing such devices according to design drawings and/or specifications, providing alarm analysis and follow-up, and troubleshooting hardware problems, and repairing and replacing control modules, I/O interface boards, relays, PLCs, power supplies, etc.

2. Helps to assure that HVAC control systems operate in the intended manner to use energy efficiently by programming system parameters to meet objectives, adjusting set points, monitoring the network, and calibrating instrumentation, metering, valves, dampers, actuators, controllers as required.

3. Helps to assure the efficient operation of the university’s HVAC systems and control systems by diagnosing control problems and by adjusting, calibrating, repairing, or overhauling the systems.

4. Supports the use of control systems to meet energy saving and comfort objectives by assisting in the development and implementation of control software for microprocessor-based control systems and developing and implementing operator control interface screens and panels.

5. Maintains and repairs all control and instrumentation such as transmitters, valve/damper actuators, servo-valves, solenoids, thermocouples, pressure/temperature gauges, chart recorders, data loggers, alarm annunciators, and level indicators.

6. Maintains and repairs variable speed drives and ramp starters for electric motors.

7. Performs journeyman level mechanical work in the installation, operation, maintenance, modification, service and repair of electric, electronic, pneumatic, electro-magnetic, and mechanical control systems by inspecting and testing those systems to locate and diagnose faults, and malfunctions, performing required repairs through replacement of inoperative parts, calibrations, trouble-shooting or adjustments, and providing an estimate of repair or replacement costs for mechanical services beyond the capability to perform.

8. Provides technical advice to the Mechanical/Electrical Maintenance Foreman and the Superintendent of Building and Equipment Maintenance on the selection of complex and up-to-date instruments and controls used in heating, ventilation and air conditioning (HVAC) systems as well as fire protection systems through independent judgment regarding the interchangeability and integrateability of manufacturers assemblies, sub-assemblies and components with existing (as well as potential replacement) requirements of HVAC and fire protection systems.

9. Maintains maximum system efficiency by installing sensing and switching devices designed to control the flow and temperature of air, steam, water, gases, and servicing, maintaining, and adjusting electric, electronic, pneumatic, electro-magnetic, and mechanical control systems and their components.
