2 – Electrical Operation

This procedure checks electrical operation of the ATS.

Be sure to close the enclosure door

before proceeding to prevent personal injury

in case of electrical system fault.

Transfer Test

The ATS should still be bypassed and isolated. Both normal and emergency sources must be available and the emergency source generator (if used) must be capable of being started; put engine starting control in automatic position. The Transfer Switch Connected to Normal light and the Normal Source Accepted light should be on.

1.Turn the Isolation Handle clockwise (approximately 7 turns) until the window shows TEST position.

NOTE: The engine generator may be signalled to start while turning the Isolation Handle. If emergency source is available, the ATS may operate to the emergency position. If it does, operate Retransfer Delay Bypass switch.

2.Perform steps 1–5 at right. Observe the status lights.

■Black square means light is on.

❐White square means light is off.

3.Turn the Isolation Handle clockwise (approximately 16 turns) to the CONN (connected) position.

4.Push in the Bypass Handle and turn it counterclock- wise until the OPEN indicator shows green.

This completes the Functional Test of the ADTB.
