3. Overview

Introduction

The Universal Automatic Transfer Switch (UATS) and Universal Generator Transfer Switch (UGTS) are the next generation of Automatic Transfer Switch (ATS) and Generator Transfer Switch (GTS) products. They are optional add-on switching units specifically designed for the FXM UPS family (FXM 650, 1100 and 2000) and the Novus Micro UPS family (Micro 300 and 1000). These switching units provide power and/or bypass capacity (automatic or manual) so that the operator may safely disconnect the UPS from line or generator power for easy removal and servicing. In bypass mode, the loads are directly connected to the line or generator power without any conditioning. Depending on the use of one and/or the other, the Transfer Switch allows the use of up to 3 different back-up sources (line, batteries and generator).

6. Operation

Transfer Switch operation and schematics

This section describes the operation of the UATS only. Specific information related to the UGTS is also covered. Figure 6.1 shows the power paths during the normal UPS mode of operation. In this mode, power flows from the utility Line In through CB1 (closed) to the UPS In, through the UPS module and back via "From UPS Out". With SW1 closed (UPS), the relay coil is energized and power from the UPS is routed to "Line Out". The output power is monitored and conditioned by the UPS.

Figure 6.1– UATS Operating in UPS mode (SW1=Closed, CB1=Closed)

Figure 6.2 shows the power paths in the Bypass mode of the UATS.

WARNING

The UPS is still energized and AC power is present at its output.

In this mode, power flows from the utility (Line In) through CB1 (closed) to the UPS In, through the UPS module and back via "From UPS Out". However with SW1 opened (Bypass), the relay coil is not energized and utility power is routed to "Line Out". The UPS is therefore bypassed and the output power follows the utility input from Line In, which is neither monitored nor conditioned. Any fluctuations in the Line In power will be directly transmitted to the Line Out output.

Figure 6.2– UATS Operating in Bypass mode (SW1=Opened, CB1=Closed)

Operation

Figure 6.3 shows the power paths in the Bypass - Service mode of the UATS. In this mode, power flows directly from the utility (Line In) to the Line Out. With CB1 opened (Service), no power appears at the AC input of the UPS, which makes it safe for the service personel to disconnect the AC input wiring and remove the UPS for servicing.

WARNING

The UPS must be powered off and disconnected from the batteries before removing it from service. Refer to the UPS Operator's Manual.

In the Bypass mode, the output power is neither monitored nor conditioned. Any fluctuations in the Line In power will be directly transmitted to the Line Out output.

Figure 6.3 – UATS Operating in Bypass - Service mode (SW1=Opened, CB1=Opened)

Figure 6.4 shows the power paths in the Inverter mode of the UATS.

In this mode, there is no AC power supply to the UPS AC input (CB1=Opened). The output power is derived solely from the UPS operating in inverter (backup) mode. Alpha does not recommend this mode for providing backup power to critical loads because the UPS will shut down as soon as backup battery string voltage falls out of specification.
