FDM128 Display Unit (One to Eight)
The FDM128 display unit uses an IFE Ethernet interface for low-voltage circuit breakers.
For all FDM, in addition to the information displayed on the Micrologic trip unit LCD, the FDM screen
shows demand, power quality, and maximum/minimum ammeter values along with histories and
maintenance indicators.
Measurement Function
Instantaneous RMS Measurements
The Micrologic trip unit continuously displays 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 trip cause is displayed.
The Micrologic A trip unit measures phase, neutral, and ground fault currents.
Micrologic E trip units offer voltage, power, frequency, and energy metering in addition to the
measurements provided by Micrologic A trip units.
Maximum / Minimum Ammeter
Every instantaneous measurement provided by Micrologic A/E trip units can be associated with a
maximum/minimum ammeter. The maximum for the highest current of the three phases, neutral, and
demand current can be reset using the Micrologic trip unit keypad, FDM display unit, or the
communication system.
Energy Metering
The Micrologic E trip units also measures the energy consumed since the last reset of the meter. The
active energy meter can be reset using the Micrologic trip unit keypad, the FDM display unit, or the
communication system.
Demand and Maximum Demand Values
Micrologic E trip units also calculate demand current and power values. These calculations can be
made using a block or sliding interval that can be set from five to sixty minutes in steps of one minute.
The window can be synchronised with a signal sent through the communication system. Whatever the
calculation method, the calculated values can be recovered on a PC through the communication
network.
Ordinary spreadsheet software can be used to provide trend curves and forecasts based on this data.
They provide a basis for load shedding and reconnection operations used to adjust consumption to the
subscribed power.
