Power Meter functions
Electronic Micrologic 5E
In addition to protection functions,
Micrologic 5 offers all the functions of
Power Meter products as well as operating
assistance for the circuit breaker:
n Display of settings
n Measurement functions:
- Energy (E)
nAlarms
n Time stamped histories and event tables
n Maintenance indicator
n Communication
Micrologic E measurement functions are made possible by Micrologic intelligence
and the accuracy of the sensors. They are handled by a microprocessor that operates
independent of protection functions.
Display
Micrologic LCD
The user can display all the protection settings and the main measurements on the
LCD screen of the trip unit.
bb Instantaneous rms current measurements
bb Micrologic E voltage, frequency and power measurements and energy metering
To make the display available under all conditions and increase operating comfort, an
external power supply is recommended.
It is indispensable to:
bb Display faults and interrupted current measurements
bb Use all the functions of Micrologic E (e.g. metering of low power and energy values)
bb Ensure operation of the communication system
The external power supply can be shared by several devices.
FDM121 display unit
An FDM121 switchboard display unit can be connected to a Micrologic trip unit using
a prefabricated cord to display all measurements on a screen. The result is a veritable
96 x 96 mm Power Meter.
In addition to the information displayed on the Micrologic LCD, the FDM121 screen
shows demand, power quality and maximeter/minimeter values along with alarms,
histories and maintenance indicators.
The FMD121 display unit requires a 24 V DC power supply. The Micrologic trip unit is
supplied by the same power supply via the cord connecting it to the FDM121.
PC screen
When the Micrologic, with or without an FDM121 switchboard display unit, is
connected to a communication network, all information can be accessed via a PC.

Instantaneous rms measurements
OK
The Micrologic E continuously display the RMS value of the highest current of the
three phases and neutral (Imax). The navigation buttons
can be used to scroll
through the main measurements.
In the event of a fault trip, the current interrupted is memorised.

Maximeters / minimeters
Every instantaneous measurement provided by Micrologic E can be associated with a
maximeter/minimeter. The maximeters for the highest current of the 3 phases and
neutral, the demand current and power can be reset via the trip unit keypad, the
FDM121 display unit or the communication system.
Energy metering
The Micrologic E also measures the energy consumed since the last reset of the
meter. The active energy meter can be reset via the keypad and the FDM121 display
unit or the communication system.

Demand and maximum demand values
Micrologic E also calculates demand current and power values. These calculations
can be made using a block or sliding interval that can be set from 5 to 60 minutes in
steps of 1 minute. The window can be synchronised with a signal sent via the
communication system. Whatever the calculation method, the calculated values can
be recovered on a PC via Modbus communication.
Ordinary spreadsheet software can be used to provide trend curves and forecasts
based on this data. They will provide a basis for load shedding and reconnection
operations used to adjust consumption to the subscribed power.
Power quality
Micrologic E calculates power quality indicators taking into account the presence of
harmonics up to the 15th order, including the total harmonic distortion (THD) of
current and voltage.

Switchboard display functions
Micrologic 5E trip units
Micrologic measurement capabilities come
into full play with the FDM121 switchboard
display. It connects to Compact NSX via
a simple cord and displays Micrologic
information. The result is a true integrated
unit combining a circuit breaker and
a Power Meter. Additional operating
assistance functions can also be displayed.
FDM121 switchboard display
FDM121 display.
Surface mount accessory.
The FDM121 is a switchboard display unit that can be integrated in the Compact
NSX100 to 630 A system. It uses the sensors and processing capacity of the
Micrologic trip unit. It is easy to use and requires no special software or settings. It is
immediately operational when connected to the Compact NSX by a simple cord.
The FDM121 is a large display, but requires very little depth. The anti-glare graphic
screen is backlit for very easy reading even under poor ambient lighting and at sharp
angles.
Display of Micrologic measurements and alarms
The FDM121 is intended to display Micrologic 5 measurements, alarms and
operating information. It cannot be used to modify the protection settings.
Measurements may be easily accessed via a menu.
All user-defined alarms are automatically displayed. The display mode depends on
the priority level selected during alarm set-up:
bb High priority: a pop-up window displays the time-stamped description of the alarm and the orange LED flashes
bb Medium priority: the orange “Alarm” LED goes steady on
bb Low priority: no display on the screen
All faults resulting in a trip automatically produce a high-priority alarm, without any
special settings required.
In all cases, the alarm history is updated.
If power to the FDM121 fails, all information is stored in the Micrologic non-volatile
memory. The data can be consulted via the communication system when power is
restored.
Status indications and remote control
When the circuit breaker is equipped with the BSCM module, the FDM121 display
can also be used to view circuit breaker status conditions:
bb O/F: ON/OFF
bb SD: trip indication
bb SDE: Fault-trip indication (overload, short-circuit, ground fault)
Main characteristics
Connection with FDM121 display unit.
bb 96 x 96 x 30 mm screen requiring 10 mm behind the door (or 20 mm when the
24 volt power supply connector is used)
bb White backlighting
bb Wide viewing angle: vertical ±60°, horizontal ±30°
bb High resolution: excellent reading of graphic symbols
bb Alarm LED: flashing orange for alarm pick-up, steady orange after operator reset if alarm condition persists
bb Operating temperature range -10 °C to +55 °C
bb CE / UL marking
bb 24 V DC power supply, with tolerances 24 V -20 % (19.2 V) to 24 V +10 % (26.4 V)
When the FDM121 is connected to the communication network, the 24 V is supplied
by the communication system wiring system
bb Consumption 40 mA
Mounting
The FDM121 is easily installed in a switchboard.
bb Standard door cut-out 92 x 92 mm
bb Attached using clips
To avoid a cut-out in the door, an accessory is available for surface mounting by
drilling only two 22 mm diameter holes.
The FDM121 degree of protection is IP54 in front. IP54 is maintained after
switchboard mounting by using the supplied gasket during installation.
Connection
The FDM121 is equipped with:
bb A 24 V DC terminal block:
vv Plug-in type with 2 wire inputs per point for easy daisy-chaining
vv Power supply range of 24 V -20 % (19.2 V) to 24 V +10 % (26.4 V)
bb Two RJ45 jacks
The Micrologic connects to the internal communication terminal block on the
Compact NSX via the pre-wired NSX cord. Connection to one of the RJ45 connectors
on the FDM121 automatically establishes communication between the Micrologic
and the FDM121 and supplies power to the Micrologic measurement functions.
When the second connector is not used, it must be fitted with a line terminator.
