Installation and operating instructions, ATS022 1. Introduction 1. Introduction This manual describes the installation and the basic operation of the automatic transfer switch ATS022 used with circuit breakers. 1.1 Use of symbols Hazardous voltage: warns about a situation where a hazardous voltage may cause physical injury to a person or damage to equipment.
1.3 Safety notes If there are doubts about safety use, the unit must put out of service. The automatic transfer switch ATS022 must be prevented from operating the circuit breaker before accessing the circuit breakers performing maintenance on circuit breakers or any electrical circuits powered by them...

Installation and operating instructions, ATS022 2. Product overview The device has an external auxiliary power supply possibility for guarantying an uninterrupted power supply for the protection devices in the case where they are not powered through the control circuit. From the display, one can choose whether the N-line is connected or not.
Installation and operating instructions, ATS022 3. Description 3. Description 3.1 ATS outputs 3.1.1 Opening/closing command to circuit breakers, DO1...DO4 The output relays command the circuit breakers to open and close its releases. The confi guration of the output relays has been designed to allow the command of any type of motor operator through a direct connection.
A Gen-set alarm prevents switching to the emergency line. In the case of the power supply from the emergency line, when an alarm occurs, ATS022 keeps the line 2 with logic OFF; to enable the logic the alarm must be reset.

If Line 1 (= the normal line) comes back, after the set time delay (TBS) the ATS022 sends an opening command to the protection device on the emergency line and the closing command to the protection device on the normal line is executed after a set time delay (TCN).

Protection devices do not respond Opening Command During the switching sequence, the ATS022 sends the opening command to the protection device on the normal line. If this is not effectively opened in fi ve seconds, the “Open 1 Failure” alarm is activated and the Alarm LED will be switched ON.
Missing of both lines The missing of both lines is indicated by a blinking Power LED. In this case, the ATS022 will be in a power saving state. If both lines are missing more than one minute, the ATS022 will shut down.
Two transformers and bus tie (Managing secondary loads): In this scenario, the ATS022 has to be able to control a third protection device used by the bus tie. ATS022 acquires the open/closed status of this device with digital input DI11 and by activating DO11 ATS022 is able to disconnect the secondary loads.
4. Operating 4. Operating Before using of the automatic transfer switch ATS022, read carefully chapter 1 “Safety notes” in order to avoid malfunctions or dangerous operating conditions. Never open any covers on the product. There may be dangerous external control voltages inside the ATS022 automatic transfer switch even if the voltage is turned off.
