To perform Electronics Mechanic and Electrician duties.
Electronics Mechanic must have extensive knowledge of electronics and apply this knowledge in the overhaul, installation, maintenance and repair of a variety of systems and numerous types of equipment. In addition, incumbent must be able to adapt methods to install new systems with existing older systems which are not compatible in most cases. Electronics Mechanic serves as a consultant to the Design Section during the planning phases of remodeling and construction, and recommend ways to integrate the new electronic systems with older existing systems. Incumbent is responsible for the following systems and equipment: HEAR - Hospital Emergency Alarm System, which is tied into the Community Disaster Control System; the emergency room call system which operates by a pencil-like transmitter, carried in the pocket of users, and sends messages to receiver units and alarms to remote locations throughout the hospital complex; nurse call systems; intercom systems; intercom system; fire alarms; radios and TV 's; TV antenna system; electronically-operated filing systems; burglar alarms; emergency generator systems; microwave ovens; electronically-controlled battery lighting systems; automatic door openers; boiler controls; dry-cleaning programs and control systems; radio station (amplifiers and tuners); movie projectors with sound; sound system in projection booth; electronic controls for wheelchairs; catholic protection control system; water level controls; ground detection units in surgery; electronic controls for glassware cleaner; incinerator flame controls; battery chargers.
Systems contain a combination of similar electronic devices, such transistors, capacitors, diodes, thyristors, resistors, etc. Some of the systems contain circuitry designed to accomplish multiple functions and are interrelated so that an inoperative circuit may impede operating performance of other circuit functions (examples: nurses call system; boiler system; etc.)
Electronics Mechanic must also repair switching units that employ photo-sensitive and photo-multiplying cells. Incumbent must be able to read and trace out trouble in very complicated circuits.
Electronics Mechanic uses a variety of test equipment and measuring devices such as signal tracer, visual-aural; field strength meter; capacitor testers; audio-wan meter; decade resistor; oscilloscope; radio-frequency signal generators; sound level meter; digital volt/ milliammeter.
Electronics Mechanic must be able to read, interpret, and apply a variety of technical electronic data such as schematic symbols and wiring diagrams. Incumbent must be able to troubleshoot and repair electronic systems and components when instruction manuals, wiring diagrams and technical information are not available.
Electrician must install, maintain and replace electric light fixtures, fluorescent tubes, ballasts and incandescent lamps. Maintains and replaces circuit breakers, maintains and repairs starter motors.
Electrician installs, maintains and repairs electrical appliances such as portable and fixed
ventilating fans, heating units, toasters, clocks, grills, etc. Incumbent also maintains and
repairs electrical ranges, floor scrubbers and floor-water vacuum units.
Electrician pulls interconnecting wire for installation of various types of equipment, repair and replace switches, wall plates, and install wall boxes. Incumbent bends and installs conduit as required from print.
Electrician uses a variety of test equipment such as VOM, VTV M, amp meter, AC-DC
and milliampere meters, meggers.
Electrician must know and constantly apply all safety rules on the handling of and application
of high voltage.
Electrician performs other similar duties as assigned, gives technical assistance to lower level electricians or electronic mechanics.
Independently determines the nature of the trouble and extent of repairs required. The VA COR spot checks work for compliance with acceptable trade practices, directives, and operating specifications.
Reference materials and manufacturers specifications are not available for most of the equipment. Incumbent must improvise and adapt techniques to install new systems and integrate the newer systems with the older systems.
Electronics Mechanic / Electrician frequently works with items that weigh from 10 to 40
pounds. Occasionally handles items over 40 pounds.
Electronics Mechanic / Electrician must bend, stoop, stretch, climb, stand, and sometimes work in awkward and cramped positions. Extensive walking may be required.
