AUTOMATION ELECTRO MECHANICAL WORKER (MARKET COMPETITIVE)

The Automation Electro Mechanical Worker (BPS-04) serves as a skilled tradesperson within the industrial establishment, responsible for the installation, preventive maintenance, and repair of automated electro-mechanical production machinery, conveyor systems, and utility equipment. The role ensures operational continuity of industrial processes by diagnosing faults in Programmable Logic Controllers (PLCs), Variable Frequency Drives (VFDs), sensors, actuators, and pneumatic/hydraulic circuits. The incumbent works under the supervision of a Foreman or Shift Engineer to maintain plant availability and adherence to production schedules in a public sector industrial environment.

Daily workflow involves reading electrical ladder diagrams and P&ID schematics, performing scheduled lubrication, alignment, and inspection of bearings, gearboxes, and couplings. The worker uses multimeters, clamp meters, megger testers, and handheld PLC programmers to troubleshoot control panel faults, replace defective I/O modules, and calibrate instrumentation such as pressure transmitters and temperature controllers. Maintenance activities are recorded in Computerized Maintenance Management System (CMMS) logs or manual logbooks. Career progression follows the BPS ladder through departmental promotion exams and trade test upgrades to Senior Worker (BPS-06), Foreman (BPS-11), and Sub-Engineer (BPS-12/16) cadres.

Selection for this Category B post is conducted strictly through a Practical Skill/Trade Test and a Direct Interview (Viva Voce); no written examination is administered. Candidates are shortlisted based on requisite technical qualifications (Matric with DAE/Certificate in relevant trade) and experience. The trade test evaluates hands-on competency in wiring, fault diagnosis, and component replacement on live or simulated industrial panels. The final merit list is compiled solely from the combined scores of the practical demonstration and the oral assessment conducted by the Departmental Selection Committee.
