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 NOR- MAL or EMERGENCY) and the Isolation Handle must be in the CONN position (window). See Figures 3–20, 3–21, and 3–22.

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).

Window indicator shows yellow when ATS is bypassed to Emergency.

Window indicator shows green when the ATS is not bypassed.

Window indicator shows yellow when ATS is bypassed to Normal.

To Un–Bypass Normal Source*

(Load connected to Normal Source)

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

To Un–Bypass Emergency Source*

(Load connected to Emergency Source)

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

Turn the handle clockwise.*

Turn the handle counterclockwise.*

Turn* the Bypass Handle clockwise until the Bypass Switch Position shows OPEN (green window indicator). The Bypassed to Normal light should go off and the Not In Automatic light should go off.
