ELECTRONIC CONTROL CENTER TECHNICIAN8345N2 Pay Grade: 21 DEFINITION OF WORK Summary This is skilled repair and maintenance work on electronic and pneumatic control devices operated and monitored by a computerized control center. Work involves performing a variety of skilled tasks in the repair, maintenance, and operation replacement of electronic and pneumatic controls of large air conditioning and heating systems controlled, operated and monitored by a programmed control center. Work includes reading schematic drawings and may include operating high pressure steam boilers. Standard Classification Factors Supervision Received - LEVEL B: "Under general supervision…" Employees working under general supervision usually receive some instructions with respect to the details of most assignments but are free to develop their own work sequences within established procedures, methods and policies. They are often physically removed from their supervisor and subject to only periodic checks. Difficulty - LEVEL B: Average… Where the employee is confronted with a variety of duties susceptible to different methods of solution which, in turn, places a correspondingly higher demand upon resourcefulness and concentration. Positions which require the analysis and evaluation of raw data and the rendering of conclusions would, in many instances, fall into this category. Complexity - LEVEL C: Work is of a standardized nature that may involve a variety of duties. Analytical thought becomes more important at this level due to increased data and changing situations. Tasks usually have several steps, some of which may not be directly related. Alternatives may exist for processes or methods to be used in solving problems. Workers at this level exercise a moderate amount of independent judgment. Work is controlled by routine review and reporting to or consultation with supervisors. When guidelines exist at this level, they tend to be more complicated or technical in nature requiring careful interpretation. Consequence of Actions or Decisions - LEVEL C: Consequences of actions or decisions at this level are limited in scope and effect as the work is reviewed occasionally. Errors may cause moderate inefficiency. Costs due to errors may be significant. Contacts - LEVEL A: The purpose of the contact is to obtain, clarify, give or screen established factual information, regardless of the type (i.e., easily understood or technical) within a well-defined relationship. Normal communication skills are required. Physical Demands - LEVEL C: The work requires moderate physical exertion. Environmental Conditions - LEVEL C: The work environment involves hazards, risks or discomforts typical of working with or around machinery with exposed moving parts, irritant chemicals, heavy equipment or abusive or hostile clientele and patients. Exposure to disagreeable weather conditions and extreme levels of temperature, ventilation, lighting and sound are normal. Protective clothing or gear and specific safety standards or procedures may be required. Serious injury is possible. Supervision/Leadership - LEVEL B: Involves functional leadership responsibility. As a "senior worker", performing essentially the same or similar work as those overseen, responsibility includes training, instructing, scheduling and reviewing. As a "project leader" may be responsible for a phase(s) of a single project which includes planning, coordinating and reviewing the work of others. This level may also involve limited administrative responsibility such as participating in the evaluation of work performance. Distinguishing Features Differs from the Power Plant Operator II class which is skilled work in the operation of low or high-pressure steam boilers in a power plant. Differs from the Electronic Control Center Supervisor class which is supervisory in nature over a staff responsible for the operation of electronic and pneumatic control devices operated and monitored by a computerized control center. EXAMPLES OF WORK PERFORMED Reads schematic drawings to pinpoint malfunctions. Checks readings on temperature and pressure at the source and compares them with those reported at the control center. Calibrates thermostats, adjusts and aligns pneumatic transmitters, and tests pneumatically controlled valve operators. Adjusts spring tensions and pilot positioners to obtain recommended operating ranges of valves, damper motors, air flow and pressure switches, and pneumatic transmission of temperature and pressure signals over long distances. Operates oscilloscope, test gauges, volt and ohm meters to test electronic circuits and replaces transistors, sensing devices and other parts. May remove asbestos according to professional and agency standards. Installs, replaces or remodels pneumatic (gas, steam and air), electrical or plain mechanical devices. REQUIRED KNOWLEDGE, ABILITIES AND SKILLS Knowledge *Knowledge of the standard practices, methods and tools used in calibrating, aligning, testing, trouble shooting and repairing electronic and pneumatic equipment. *Knowledge of heating and air conditioning fundamentals, and basics of automatic control systems and their components. Abilities *Ability to work from drawings and specifications, to analyze malfunctions and trace circuits, and to operate test equipment. *Ability to understand and carry out oral and written instructions. *Ability to use the tools, materials and equipment used in testing and repairing electronic and pneumatic controls. *Ability to locate and adjust defects in electronic and pneumatic controls. *Necessary at Entry MINIMUM REQUIREMENTS: Two years of experience in the operation, maintenance and repair of electronic and pneumatic controls in a central control and monitoring center of a large air conditioning and heating system or similarly complex system. Education may be substituted for experience as determined relevant by the agency. NC: 06/93 |
