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

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.
