TECNOWARE ATS Automatic Transfer Switch 16A Single Phase User Manual

TECNOWARE ATS Automatic Transfer Switch 16A Single Phase

Introduction

This ATS product is designed with two independent power inlets to supply power to the load from a primary power source. Should primarily power source fail, the secondary will automatically back up the connected equipment without any interruption. The transfer time from one line to another is seamless to the connected equipment. After switching to a secondary power source, the ATS can also switch power back to the primary input when power to the primary input is restored.
Package contents:

• ATS module
• User manual
• mounting brackets

Installation

NOTE: Before installation, please inspect the unit. Be sure that nothing inside the package is damaged.

Mounting the Unit
The unit can be mounted in a standard 19″ rack. Fasten the mounting brackets to the unit using the screws provided. With brackets attached securely, users can mount the unit in a standard 19″ rack as shown below.

NOTE: If the temperature around the unit will rise above 40 °C, ventilation is required

Connecting the Unit
For connecting the ATS, plug “input source A connector” and “input source B connector” to the two independent power sources or UPSs depending using the SCHUCKO IEC or IEC IEC 16A cables supplied. Plug the user load to the output 10A (“Output 1 and 2”) or 16A (“Output 3”) sockets depending on user’s requirements.

Operation

Power On/Off
Put the input power switch in “ON” position. The output will then be supplied by the source set as selected.

Communication Port

The ATS is supplied with the following communication ports:

• Serial port is available with RS232 com. port and USB com. port on the front panel.
  NOTE: the use of one port automatically excludes the other.

• Contacts port on the rear panel.

Serial Ports: RS-232 & USB connectors

NOTE: The utilization of the communication port is optional and it is not necessary for the correct functioning of the ATS.

Contact Ports
The contacts port is formed using six (6) pins numbered from left to right (see fig. 1), which can be connected to an external monitoring system (such as a BMS) in order to monitor the operational status of the ATS. The external equipment must respect the voltage and current characteristics of the contacts port.

The contacts port provides the following pins:

• Pin 1: common contact.
• Pin 2: “Source B” active contact (if the contact between “pin 1” and “pin 2” is closed, output is supplied by “Source B”).
• Pin 3: “Source A” active contact (if the contact between “pin 3” and “pin 1” is closed, output is supplied by “Source A”).
• Pin 4: “Source A” status OK contact (if the contact between “pin 4” and “pin 1” is closed, “Source A” is present and regular).
• Pin 5: “Source B” status OK contact (if the contact between “pin 5” and “pin 1” is closed, “Source B” is present and regular).
• Pin 6: Status OK contact (if the contact between “pin 6” and “pin 1” is closed, ATS functioning status is regular).

The following diagram shows the functioning of the contacts port.

ATTENTION: The pins of the contact port are able to carry maximum current of 8A and maximum voltage of 250Vac.
