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. 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.

QBlack square means light is on. S White square means light is off.

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

4.Push in the Bypass Handle and turn it counterclock- wise to the OPEN position.

This completes the Functional Test of the ATB.

The Transfer Switch Connected

1to Normal and Normal Source Accepted lights should be on.

Turn and hold Transfer Control switch clockwise to Transfer

2Test until the engine starts and runs (within 15 sec.). The Emergency Source Accepted light should come on.

Transfer switch will operate to the Emergency position after Feature 2B time delay. The

3Transfer Switch Connected To Emergency light should come on and Load Connected to Normal light goes off.

Transfer switch will operate back to Normal position after Feature 3A time delay. For im- mediate retransfer turn Transfer

4Control counterclockwise to Retransfer Delay Bypass. The Transfer Switch Connected To Normal light should come on; Transfer Switch Connected to Emergency light should go off.

The engine–generator will stop after the Feature 2E time delay

5(unloaded running engine cool- down). The Emergency Source Accepted light should go off.
