Elevator Engineer (Re-announced)

Major Activities

1. Technical Operations & Maintenance: Maintain and troubleshoot elevators, lifts, and associated control systems, including controllers, VFDs/drives, door operators, safety circuits, interlocks, encoders, sensors, limit switches, landing controls, car operating panels, and emergency systems. Troubleshoot elevator faults related to power supply, control boards, communication faults, input/output signals, relays, contactors, sensors, door systems, motor drives, and safety circuits. Carry out functional testing of elevators after maintenance or repair and verify proper operation of doors, leveling, acceleration/deceleration, emergency functions, alarms, communication systems, and safety devices. Maintain and troubleshoot access control systems, including card readers, biometric devices, controllers, magnetic locks, electric strikes, exit buttons, door sensors, request-to-exit devices, power supplies, and associated communication networks. Investigate access control failures such as door not opening, unauthorized access, reader communication failure, lock malfunction, controller failure, power loss, and incorrect input/output signals. Maintain and troubleshoot electronic control and Building Management System (BMS) panels, including Automated Logic control modules, universal input/output modules, sensors, actuators, relays, terminal blocks, and control wiring. Diagnose field device and I/O faults, including temperature, pressure, humidity, differential pressure, status, alarm, and control signals connected to automation systems. Check and troubleshoot 24 VAC/24 VDC power supplies, control circuits, communication networks, signal wiring, grounding, terminal connections, and control modules. Respond promptly to emergency breakdowns, elevator entrapment incidents, access control failures, and critical electronic system alarms, following approved safety and emergency procedures. Conduct preventive maintenance inspections, identify abnormal conditions, and recommend replacement or refurbishment of defective components before failure occurs. Review electrical/electronic drawings, control schematics, wiring diagrams, equipment manuals, and technical documentation during troubleshooting and maintenance activities. Supervise and technically evaluate elevator, access control, BMS, and specialized electronic-system contractors, ensuring work is completed according to approved specifications and safety requirements. Support installation, testing, commissioning, modification, upgrading, and modernization of elevator and electronic control systems. Maintain accurate asset registers, maintenance records, fault reports, spare-parts lists, test results, and equipment history for all assigned systems. Ensure adequate availability of critical spare parts, electronic modules, sensors, relays, power supplies, controllers, and other essential components. Conduct post-repair testing and verification to ensure that equipment is returned to safe, stable, and reliable operation.
2. Technical Systems Under Responsibility: The position is responsible for the following systems: a) Elevator & Vertical Transportation: Elevator controllers, VFDs, motors, door operators, safety circuits, interlocks, encoders, limit switches, sensors, landing/car operating panels, alarms, emergency communication, and related control systems. b) Access Control: Access control panels/controllers, card and biometric readers, magnetic locks, electric strikes, exit buttons, door contacts, request-to-exit devices, power supplies, communication interfaces, and associated software/network connections. c) Electronic & BMS Controls: Automated Logic control modules such as MEx816u, I/O modules, universal inputs/outputs, sensors, actuators, relays, contactors, control transformers/power supplies, terminal blocks, communication networks, and associated field wiring.
3. Troubleshooting & Diagnostic Responsibilities: The Engineer shall be capable of systematically troubleshooting issues such as: Elevator controller and drive faults. Elevator door opening/closing and leveling problems. Safety circuit and interlock failures. Encoder, limit-switch, and sensor faults. Communication failure between controllers and field devices. Access card/biometric reader failures. Magnetic lock and door-release problems. BMS input/output signal failures. Sensor and actuator malfunction. 24 VAC/24 VDC control power failures. Relay, contactor, terminal, and wiring faults. Intermittent electronic and communication faults. Repeated equipment alarms and unexplained system shutdowns.
4. Safety & Compliance: The Engineer ensures that all maintenance and troubleshooting activities are conducted in accordance with applicable electrical safety requirements, elevator safety requirements, manufacturer recommendations, approved maintenance procedures, isolation/LOTO practices, and organizational HSE policies.
