EM530 and EM540
Introduction
EM530 is an energy analyzer connected through 5 A current transformers, for two- and three-phase systems up to 415 V L-L.
EM540 is an energy analyzer for direct connection up to 65 A, for two- and three-phase systems up to 415 V L-L.
In addition to a digital input, the unit can be equipped, according to the model, with a static output (pulse or alarm), a Modbus
RTU communication port or an M-Bus communication port.

PFA models
Easy connection function: irrespective of the current direction, the power always has a plus sign and contributes to increase
the positive energy meter. The negative energy meter is not available.
PFB models
For each measuring time interval, the individual phase energies with a plus sign are summed to increase the positive energy
meter (kWh+), while the others increase the negative one (kWh-).
Example:
P L1= +2 kW, P L2= +2 kW, P L3= -3 kW
Integration time = 1 hour
kWh+ = (2+2) x1h = 4 kWh
kWh- = 3 x 1h= 3kWh

7
EM530/EM540 - User manual | CARLO GAVAZZI Controls SpA
PFC models
For every measuring interval time, the energies of the single phases are summed; according to the sign of the result, the
positive (kWh+) or negative totalizer (kWh-) is increased.
Example:
P L1= +2 kW, P L2= +2 kW, P L3= -3 kW
Integration time = 1 hour
+kWh=(+2+2-3)x1h=(+1)x1h=1 kWh
-kWh=0 kWh
UCS (Universal Conguration Software)
UCS is available in desktop and mobile versions.
It may connect to EM530 or EM540 via RS485 (RTU protocol, desktop version only).
UCS allows to:
• set up the unit (online or offline);
• display the system state for diagnostic and setup verification purposes
Overview of the UCS functions:
• Setting up the system with energy meter connected (online setup)
• Defining the setup with energy non connected, then applying it later (offline setup)
• Displaying the main measurements
• Displaying the state of inputs and outputs
• Displaying the state of the alarms
• Recording the measurements of selected variables
• Check connection and correct wiring errors

Information and warnings
Symbol Description
ALARM (blinking icon): the value of the variable has exceeded the threshold set.
WIRING ERROR (steady icons): a wiring fault has been detected, the control operates correctly if the
selected system is 3Pn and for each phase:
• the power is positive (imported),
• PF > 0.7 L or PF > 0.96 C.
Serial communication state (reception / transmission)
The association of the phase terminal or the direction of the currents have been modified via UCS
software to correct virtually a wiring fault. To view the current setup of the terminals, access the info
screens ( MENU > INFO > TERMINAL).

EM530/EM540 - User manual | CARLO GAVAZZI Controls SpA
Essential information
Alarms
Introduction
EM500 manages a measured variable alarm. To set the alarm, define:
• the variable to be monitored (VARIABLE)
• alarm activation threshold value (SET POINT 1)
• alarm deactivation threshold value (SET POINT 2)
• alarm activation delay (ACTIVATION DELAY)
Variables
The unit can monitor one of the following variables:
• system active power
• system apparent power
• system reactive power
• system power factor
• phase-neutral voltage (OR logic)
• phase-phase voltage (OR logic)
• current (OR logic)
Note: if you select a current or a voltage, the analyzer simultaneously monitors all the phases available in the set measurement
system and triggers the alarm when at least one of the phases is in alarm (OR logic)
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.
(s)
ON
Set 1
Set 2
Delay
Down alarm (Set point 1 < Set point 2)
The alarm activates when the monitored variable drops below the Set 1 value for a time equal to the activation delay (Delay) and
deactivates when it exceeds Set 2.

Essential information
EM530/EM540 - User manual | CARLO GAVAZZI Controls SpA
DMD values
Average value calculation (dmd)
EM530 and EM540 calculate the average values of the electrical variables within a set integration interval (15 min by default).
Integration interval
The integration interval starts at switch-on or when the reset command is issued. The first value is displayed at the end of the first
integration interval.
Example
The following is a sample integration:
• reset at 10:13:07
• set integration time: 15 min.
The first value displayed at 10:28:07 refers to the interval from 10:13:07 to 10:28:07.
LCD display
Home page
The unit may display the default measurement pages after no operation has been performed for five minutes, if the screensaver
is enabled and the screensaver type is as “Home page” (default value).
Notes: if you select a page that is not available in the set system, the unit displays as its home page the first available page. In
MID models the home page cannot be changed and displays the active energy meter.
Backlight
EM530 and EM540 are equipped with a backlight system. You can set whether the backlight shall always be ON or whether it
should automatically switch off after a given interval has elapsed since a button was pressed (1 to 60 minutes).
Screensaver
If the SCREENSAVER function is enabled (default setting), after 5 minutes have elapsed since a button was pressed the unit will
display the home page if the screensaver type is “Home page” (default setting), or it shall activate the slideshow function, which
displays the selected pages on a rotating basis.
Notes: In MID models the screensaver setting is “Homepage” and cannot be changed.
Page lter
The page filter makes it easier to use and browse the measurement pages. When you use the buttons, the unit shall
only display the pages you are most interested in, which can be selected through the UCS software (S1 version) or is pre-defined
(O1 and M1 version)
Note: to display all the pages without using the UCS software, you can disable the page filter from the SETTINGS MENU
(DISPLAY → PAGES→ ALL). By default, the pages included in the filter are: 1 (kWh+ TOT, kW), 2 (kWh- TOT, kW), 5 (VLN, VLL,
Hz), 7 (kvarh+ TOT, kvar), 8 (kvarh- TOT, kvar), 25 (L1 A, L2 A, L3 A), see “Measurement pages” on page 13.

Restoring the factory settings
Restoring the settings using the RESET menu
From the RESET menu you can restore all the factory settings. At start-up the QUICK SET-UP menu shall be available again.
Notes: meters are not reset. In MID models you cannot reset the CT current transformer ratio (CT RATIO).
