UCS (Universal Configuration Software)

UCS is available in desktop and mobile versions.

It may connect to EM511 via RS485 (RTU protocol, desktop version only).

UCS allows to:

lset up the unit (online or offline);

ldisplay the system state for diagnostic and setup verification purposes

Overview of the UCS functions:

lSetting up the system with energy meter connected (online setup)

lDefining the setup with energy non connected, then applying it later (offline setup)

lDisplaying the main measurements

lDisplaying the state of inputs and outputs

lDisplaying the state of the alarms

lRecording the measurements of selected variables

Interface

Introduction

EM511 is organized into two menus:

lMeasurement pages: pages allowing to display the energy meters and the other electrical variables

lMain menu, divided into three sub-menus:

o» SETUP: pages allowing to set the parameters

o» INFO: pages displaying general information and the set parameters

o» RESET: pages allowing to reset the partial counters and the dmd calculation, or to restore the factory settings

Essential information

Alarms

Introduction

EM511manages a measured variable alarm. To set the alarm, define:

lthe variable to be monitored (VARIABLE)

lalarm activation threshold value (SET POINT 1)

lalarm deactivation threshold value (SET POINT 2)

lalarm activation delay (ACTIVATION DELAY)

Variables

The unit can monitor one of the following variables:

lactive power

lapparent power

lreactive power

lpower factor

lvoltage

lcurrent

Alarm types

Up alarm (Set point 1 ≥ Set point 2)

The alarm activates when the monitored variable exceeds the Set 1 value for a time equal to the activation delay (Delay) and

deactivates when the values drops below Set 2.
