Task D‑25 Installs, programs, services and maintains automated control systems.

Task Descriptor

All electrical motors need a method to be started and controlled. These controls can be complex automated systems. Automated control systems are often programmable systems such as PLC and distributed control system (DCS).

For the purpose of this standard, installation includes both new installations and upgrading of systems by removing and replacing components.

Construction electricians install and service automated control systems by troubleshooting, diagnosing faults, and repairing them. They perform maintenance to ensure automated control systems are in good operating condition. They also program and configure the automated control systems to meet operational requirements.

Industry Expected Performance

At a journeyperson level of performance, all tasks must be done with minimal direction and supervision.
