Motor Controllers Sample Clauses

The 'Motor Controllers' clause defines the requirements and specifications for the devices that regulate and control the operation of electric motors within a system. It typically outlines the types of controllers to be used, their performance standards, installation procedures, and any necessary safety features or certifications. For example, it may specify whether variable frequency drives or soft starters are required, and detail how controllers should interface with other system components. The core function of this clause is to ensure that motor controllers are properly selected and installed to guarantee safe, efficient, and reliable motor operation, thereby reducing the risk of equipment failure and ensuring compliance with relevant standards.
Motor Controllers. Motor controllers shall be marine type, complying with the requirements of the UL Standard for Industrial Control Equipment, or IEC equivalent, and USCG 46 CFR Subchapter J. Controllers shall be manufactured by Square D or equal. Motor controllers not provided as parts of integrated machinery packages shall be from the same manufacturer. Controller enclosures shall be USCG approved. Hardware exposed to the weather, dampness or corrosive environments shall be stainless steel, grade 316 or better. Provide filters in the air intake where panels are force ventilated. Controllers installed in interior locations shall have 265 270 275 280 285 290 295 300 NEMA 12 enclosures. Controllers located in areas accessible to the public shall have locking devices similar to and keyed to match the panel boards. Provide contactors with as many auxiliary contacts as required for each control, alarm and monitoring function. Mount operating controls in the front of the enclosure. Provide power available lights, and illuminated pushbuttons for motor running indication. Provide push-to-test pilot lights. Run indicator lights shall be green for single speed motors; amber for low speed and green for high speed in the case of two speed motors. Automatic controllers shall have blue indicator lights for automatic control, and green for motor running on hand-off-auto (HOA) controllers. Indicator lights and controls shall operate at 120 V or less, and shall be powered from the controlled circuit. Provide control transformers as necessary. Remote operating stations shall be provided where control from more than one location is required, where the motor starter cannot be located near the motor, or as required by the Regulatory Bodies. All motor controllers shall utilize appropriately rated contactors for the motor horsepower to be controlled. Starters shall have three-pole, external manual melting alloy type thermal overload devices, or have ambient compensated bi-metallic thermal overload relays. Reduced voltage type controllers shall be required for motors over 50 hp to limit inrush current to acceptable limits for the generator and to minimize voltage dip. Prepare voltage dip calculations to verify proper selection of controllers for the service intended and submit to Owner's Representative for approval. Motor controllers with a working power rating of 1 hp or greater shall typically be provided with low voltage protection (LVP) to avoid excess starting currents when power is lost and...
