2 – Electrical Operation

This procedure checks electrical operation of the ADTS.

Close enclosure door before proceeding to prevent personal injury in case of electrical system fault.

Transfer Test

The ATS should still be bypassed. 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 counterclockwise to the 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. See Figure 1–3.

■Black square means light is on.

❐White square means light is off.

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

4.Turn Bypass Handle clockwise to the OPEN position.

This completes the Functional Test of the 7ADTB.
