SECTION 2 TESTING & SERVICE

TRANSFER TEST

REPLACEMENT PARTS

Test the Automatic Transfer Switch portion of the 7000 Series ATB at least once a month. This procedure checks the electrical operation of the Transfer Switch and Controller. Put the engine–generator starting con- trol (at the engine–generator set) in automatic mode.

In the following test the generator will start, the load will be transferred to the Emergency source, then back to the Normal source. An interruption to the load will occur, unless the the Transfer Switch contacts are by- passed before the test. See pages 3–1 and 3–2 for by- passing & isolating instructions if no interruption of load is required.

Be sure to close the enclosure door before proceeding to prevent personal injury in case of electrical system fault.

Perform the five–stepElectrical Operation – Transfer Test procedure on page 1–4.

PREVENTIVE MAINTENANCE

Reasonable care in preventive maintenance will insure high reliability and long life for the 7000 Series ATB. An annual preventive maintenance program is recom- mended.

ASCO Services, Inc. (ASI) is ASCO Power Technologies’ national service organization. ASI can be contacted at 1–800–800–2726 for informa- tion on preventive maintenance agreements.

Checklist for Yearly Inspection

Hazardous voltage capable of causing shock, burns, or death is used in this switch. Deenergize both Normal – Emergency power sources before performing inspections!

SClean the ATB enclosure. Brush and vacuum away any excessive dust accumulation. Remove any moisture with a clean cloth.

SCheck the transfer switch contacts. Remove transfer switch barriers and check the condition of the contacts. Replace contacts when pitted or worn excessively. Reinstall the barriers carefully.

SMaintain transfer switch lubrication. If switch is subjected to severe dust or abnormal operating conditions, renew factory lubrication on all move- ments and linkages. Relubricate solenoid operator if TS coil is replaced. Don’t use oil; order lubrica- tion kit 75-100.

SCheck all cable connections & retighten them.

Replacement parts are available in kit form. When ordering parts provide the Serial No., Bill of Material No. (BOM), and Catalog No. from the transfer switch nameplate. For service call ASCO Services at 1–800–800–2726.

DISCONNECTING THE CONTROLLER

The harness disconnect plugs are furnished for repair purposes only and should not have to be unplugged. If the controller must be isolated, follow these steps:

Bypass–Isolation Switch is energized! Do not touch isolation contact fingers; shock, burns, or death could result!

Disconnecting the Plugs

1.Bypass and Isolate the Automatic Transfer Switch.

2.Open the upper enclosure door.

3.Separate the two quick disconnect plugs by squeez- ing the latches. Do not pull on the harness wires.

Reconnecting the Plugs

1.The ATS should be still bypassed and isolated.

2.The two harness plugs and sockets are keyed. Carefully align the plugs with the sockets and press straight in until the latches click.

3.Close the enclosure doors.

4.Follow Return to Service instructions on page 3–3.

7ATB specifications

The Emerson 7ATB represents a significant advancement in underwater technology designed for deepwater exploration and data collection. This innovative submersible vehicle is engineered to perform a range of tasks, from scientific research to natural resource exploration, while ensuring safety and efficiency in performance.

One of the standout features of the 7ATB is its robust design, capable of withstanding extreme pressures found at significant ocean depths. The submersible is made from high-strength materials that not only protect its internal components but also reduce weight for enhanced maneuverability. Its streamlined shape minimizes drag, allowing for efficient navigation through the underwater environment.

The 7ATB is equipped with state-of-the-art sensor technology. This includes multi-beam sonar for accurate mapping of the seafloor and advanced imaging systems that capture high-resolution, real-time images and video. The incorporation of in-situ chemical sensors enables the vehicle to analyze water quality and detect various substances, making it invaluable for environmental monitoring.

A key characteristic of the Emerson 7ATB is its advanced autonomy capabilities. The submersible can operate independently for extended periods through automated navigation and mission planning. This autonomy is supported by sophisticated algorithms that allow it to maneuver efficiently and avoid obstacles while performing pre-programmed tasks. Furthermore, it boasts a flexible payload system, accommodating a variety of instruments tailored to specific missions.

In terms of communication, the 7ATB employs a hybrid system that combines acoustic and satellite technologies to maintain a reliable link with the control center, even in remote locations. This ensures real-time data transmission, enabling scientists and operators to make informed decisions during operations.

The vehicle also features battery technology designed for extended operational life, reducing the need for frequent retrieves. This efficiency not only enhances productivity but also minimizes the logistical challenges often associated with deep-sea missions.

Overall, the Emerson 7ATB is a remarkable combination of durability, advanced technology, and operational efficiency, positioning it as a go-to solution for underwater exploration and research in challenging environments. Its innovative features set a new standard for submersible vehicles, revolutionizing how we explore and understand the ocean depths.
