This one day continuation of the basic (first day) seminar is designed to provide additional knowledge and skills required when testing and troubleshooting circuits that include solid state components like PLCs, solid state relays (SSRs), Motor Drives, and solid state switches.
More advance problems caused by over currents, sags/swells, transients, harmonics, overloaded neutrals, and heat related problems will be covered by taking measurements and troubleshooting circuits. Participants will build and test electrical circuits that are used to understand how the circuits should operate, and how to test and troubleshoot them.
Topics, circuits, and equipment covered include:
- Learn how to test and wire any IEC (imported) Wye/Delta three-phase motor without using the motors wiring diagram and what the expected readings should be before power is applied and how to troubleshoot the motor after power is applied.
- Connecting the drives control circuit to different types of sourcing and sinking inputs, to control motor starting, stopping, jogging and direction of rotation.
- The difference between troubleshooting electromechanical and solid state components.
- Connect a motor drive to control the speed of a motor using analog inputs (solar panels, potentiometers, etc.).
- Connecting and testing circuits that include a PLC for controlling the circuit. Testing procedures for testing for phase loss, improper phase sequence, voltage imbalance, and current imbalance.
