BYPASSING & ISOLATING (continued)

RETURN TO SERVICE continued*

This procedure explains how to return the Bypass Switch Handle to the OPEN position. The Bypass Handle must be in the CLOSED position (yellow indicator on NORMAL or EMERGENCY) and the Isolation Handle must be in the TEST position (window). If the handles are not in these positions, refer to Return to Service on page 3–3. See Figures 3–11, 3–12, and 3–13.

You can only bypass to the same source that the ATS is connected. Solenoid interlock prevents incorrect operation.

1Observe which Bypass Switch Position indicator is yellow (NORMAL or EMERGENCY) at the Bypass Switch Handle. This indicates the source connected to the load.

2Un–Bypass to same source as the Bypass Switch Position as follows (select Normal or Emergency).

Indicator shows:

green O OPEN when the ATS is not bypassed.

To un–Bypass Normal push in handle all the way & turn it counterclockwise.*

Indicator shows:

yellow O EMERGENCY CLOSED when ATS is bypassed to Emergency or

yellow O NORMAL when ATS is bypassed to Normal Source.

To un–Bypass Emergency pull out handle all the way & turn it counterclockwise.*

(Load connected to Normal Source)

The Transfer Switch Connected To Normal light is on and Transfer Switch Connected To Emergency light is off.

Push in* the Bypass Handle then turn it counterclock- wise until Bypass Switch Position shows OPEN (green indicator). The Unit Not in Automatic light should be off.
