Functional Test

Read all instructions on the Wiring Diagrams and labels affixed to the ADTB. Note the control features that are provided and review their operation before proceeding.

After installing the ADTB check the following:

–Bypass Handle should be in the OPEN position.

–Isolation Handle should be in the CLOSED position.

–CN transfer switch should be CLOSED.

–CE transfer switch should be OPEN.

If handles are not in correct positions, follow instructions for Bypassing and Isolating the automatic transfer switch in Section 3. Do not force the handles. Electrical interlocks prevent a wrong sequence of operation.

1 – Voltage Checks

First check nameplate on transfer switch; rated voltage must be the same as normal and emergency line voltages.

Use extreme caution when using a meter to measure voltages. Do not touch power terminals; shock, burns, or death could result !

Perform steps 1–6 at the right. Observe the status lights. See Figure 1–3.

■Black square means light is on.

❐White square means light is off.

*If necessary, adjust voltage regulator on generator per the manufacturer’s recommendations. The ADTB will respond only to rated voltage specified on the nameplate.
