1.1 INTRODUCTION
1.1 INTRODUCTION
This module controls up to three power sources: mains and two generators (MGG). It is also possible to
configure it to control mains and one generator (MG) or just two generators (GG). It features isolated
measurement of the voltages and frequency on all three sources as well as the current on the load side.
It has four operating modes selectable by the user: OFF, AUTO, MAINS, G1 or G2.
This module can be configured to be used as ATS or ATSO.
The user interface consists of a Graphical LCD display. A mode push button is provided to select the
operating mode and four push buttons are used to access a menu of parameters. The menu gives access to
all timers, set points and other parameters relevant to the control and protection of the installation.
This module comes with RS485, USB and Ethernet communication ports. It also features a 4GB MicroSD card
for data and event logging. Data and event retrieval is done by either USB port or Internet through a
dedicated website.
The firmware could be easily upgraded on site via the USB interface using a desktop application or any smart
phone with a free Android app.
