Installation and operating instructions, ATS022	3.	Introduction

3. Introduction

3.1 Product overview

The automatic transfer switch ATS022 is used in all installations where switching is required between two lines to ensure the supply of loads in case of a fault on one line.

ATS022 selects the power supply line by acting directly on the CBs provided on the lines: ATS022 can be used with automatic CBs and ABB SACE switch-disconnectors.

The device monitors the voltage of the main line and emergency line and records the following faults:

•Maximum and minimum voltage

•Maximum and minimum Frequency

•Phase balance

•Voltage imbalance

•Frequency imbalance

ATS022 does not require an auxiliary safety power supply since it is powered directly by the line voltages.

If both lines are absent, ATS022 enters Powersave mode (maximum duration 1 minute) in which the device is active and in stand-by for one of the power supply lines to be restored. When the Powersave period ends, the LED switches off and the device awaits a line voltage. The moment the main or the emergency line is restored, the unit analyses the conditions of the lines monitored and the status of the circuit breakers and proceeds with the switching operation in accordance with the situation concerned.

The safety auxiliary supply is obligatory in the following cases:

•utilisation of Modbus RS485 communication

•utilisation in systems with rated frequency 16 2/3Hz

•utilisation in single-phase systems with Un 57,5…109VAC

A 24VDC ….110VDC auxiliary safety power supply can be used (-10%, +15%).

ATS022 can be used in systems with rated frequency 50Hz, 60Hz, 400Hz, 16 2/3 Hz that can be set from the menu.

The device can be used in systems with single-phase, three-phase with Neutral and three-phase without neutral, setting can be done from the menu. ATS022 makes it possible to select from the display a different distribution system between Line LN1 and Line LN2. ATS022 can be used in manual or automatic mode. In the first case the circuit breakers must be controlled by means of the pushbuttons present on the front panel of the device, while in automatic mode, the switching logic is controlled directly by the device

The device is equipped with a front graphic display by means of which the user can check the settings and display the status of the unit and the circuit breakers connected to it.

It is also possible to integrate the ATS022 device inside a communication network which uses the Modbus RS485 protocol.

3.2Application scenarios

The ATS022 device can be used in the following applications:

•Main line – Emergency line switching

•Main line – Emergency generator switching

ATS022 makes it possible to operate a thrid circuit breaker CB3 and can therefore also be used in the following applications which can be set on the menu:

•non priority loads control with CB3 on starting line (3CBs NPL)

•non priority loads control with CB3 Bus Tie (3CBs NPL Bus Tie)

•control of two independent power supply lines separated by Bus Tie (3CBs Bus Tie)

3. Introduction	Installation and operating instructions, ATS022

The ATS022 also makes it possible to select which of the lines is the main one and which one is secondary, also with the system running.

The following selections are possible, set from the menu:

•Main line: Line LN1

•Main line: Line LN2

•No priority line

In automatic mode, it is possible to select whether or not the switching procedure must include inverse switching.

The following selections are possible:

•with inverse procedure

•without inverse procedure

4.3 Non priority loads control (NPL)

Description

In case of main line failure the ATS022 starts the switching procedure and controls the non priority loads by opening closing circuit breaker CB3.

ATS022 acquires the CB3 open/close status from the dedicated input DI11 and commands the opening and closing by activating output DO11.

The application of non priority loads requires the use of two CT-AWE typed timed relays for operating the opening and closing of CB3.

Two configurations are possible for utilisation depending on the position of circuit breaker CB3:

•CB3 in Bus Tie position (3CBs NPL – BUS TIE)

•CB3 on starting line (3CBs NPL).

It is possible to select from two options from the menu on the display:

•only disconnection of non priority loads by opening CB3 (manual re-closure). In this case timed relays CT-AWE are not necessary

•disconnection and re-connection of non priority loads by opening and closing of CB3

For more details refer to the wiring diagrams of the product.
