BYPASSING THE ATS*

This procedure explains how to Bypass the closed transfer switch contacts. Bypassing is required before the Transfer Switch can be tested or isolated. The Bypass Switch Handle must be in the OPEN position (green window indicator) and the Isolation Handle must be in the CONN [connected] position (window indicator). The TS Connected light must be on. See Figures 3–1, 3–2, 3–3.

You can only bypass to the same source that the Transfer Switch is connected.

Solenoid interlock prevents incorrect operation.

1.Observe which Transfer Switch Connected To light is on (Normal or Emergency) on the door. This is the position of the transfer switch (see Figure 3–2).

2.Follow the directions on next page to Bypass to the same source as connected to transfer switch (select Normal or Emergency).

Window indicator shows yellow when ATS is bypassed to Emergency.

Window indicator shows green when the ATS is not bypassed.

Upper green light is on if Transfer Switch is on Normal.

Lower red light is on if Transfer Switch is on Emergency.
