SECTION 2 TESTING & SERVICE

TRANSFER TEST

REPLACEMENT PARTS

Test the Automatic Delayed–Transition Transfer Switch portion of the 7000 Series ADTB at least once a month. This procedure checks the electrical operation of the Transfer Switch and Controller. Turn the Engine Control switch to Auto and 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 bypassed be- fore the test. See pages 3–1 and 3–2 for bypassing & iso- lating 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 four–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 ADTB. An annual preventive maintenance program is recom- mended.

ASCO Services, Inc. (ASI) is Automatic Switch Company’s national service organization. ASI can be contacted at 800-800-2726 for information 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!

❐Clean the ATS enclosure. Brush and vacuum away any excessive dust accumulation. Remove any mois- ture with a clean cloth.

❐Check 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.

❐Maintain transfer switch lubrication. If switch is subjected to severe dust or abnormal operating con- ditions, renew factory lubrication on all movements and linkages. Relubricate solenoid operator if TS coil is replaced. Don’t use oil; order lubrication kit 75-100.

❐Check all cable connections & retighten them.

Replacement parts are available in kit form. When or- dering parts provide the Serial No., Bill of Material No. (BOM), and Catalog No. from the transfer switch name- plate. For service call ASCO Services at 1–800–800–2726; you will be put in contact with your local ASI office.

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. Care- fully 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.
