3 – Electrical Operation

This procedure will check the electrical operation of the Automatic Transfer Switch. See Figure 1–6.

Close the transfer switch enclosure door and tighten the screws before you test electrical operation.

Transfer Test

Both normal and emergency sources must be available and the emergency source generator (if used) must be capable of being started in this procedure.

Perform steps 1 through 8 at the right. Observe the status lights. See Figure 1–6.

OBlack circle means light is on. P White circle means light is off.

NOTE: If Motor Load Transfer feature is activated, then transfer may not occur immediately after the respective time delays. Transfer will only occur when the phase relationship between sources is correct.

This completes the Functional Test of the ASCO Series 300 Automatic Transfer Switch. Leave the engine–generator starting control in the automatic position.
