OICEW Task 6.1.E

Understand motor controllers, sequential control, and high voltage

In order to satisfy NVIC 17-14 Task 6.1.E , MMA students must:

STCW Competence

Knowledge, Understanding, and Proficiency

Operate electrical, electronic and control systems

OICEW-B1.1 Basic configuration and operation principles of the following electrical, electronic and control equipment

Electrical motors including starting methodologies

High-voltage installations

Sequential control circuits and associated system devices

Condition	Behavior	Standard
On a vessel of at least 1,000 HP, or in a laboratory or workshop,	the candidate demonstrates knowledge of motor controllers, other sequential control systems, and High Voltage properties and precautions. All The assessment is required for all OICEW endorsements regardless of any limitations for propulsion mode and/or vessel equipment.	The candidate: Explains the sequence of events that lead to the starting of at least two motor controllers; one reversing and one non- reversing; Describes the basic operation of an electro-pneumatic or electro-hydraulic sequence system as chosen by the assessor; and Lists the inherent dangers of High Voltage systems and enumerates special safety precautions to take when operating and troubleshooting such system.
