FDM128 Display

The Micrologic trip unit measurement capabilities are fully utilized with the FDM128 display. The

FDM128 display connects to Ethernet communication using the RJ45 port and displays Micrologic trip

unit information. The result is an integrated unit combining a circuit breaker with a power meter.

Additional operating assistance functions can also be displayed.

The FDM128 display unit can be connected to a Micrologic COM option (BSCM). It uses the sensors

and processing capacity of the Micrologic trip unit and requires no special software or settings. The

FDM128 is a large display, but requires very little depth. The anti-glare graphic screen is backlit for

easy reading even under poor ambient lighting and at sharp angles.

The FDM128 display is designed to manage up to eight devices (PowerPact H/J/L/P/R or Masterpact

NW/NT circuit breakers).

Display of Micrologic Trip Unit Measurements and Trips

The FDM128 is intended to display Micrologic 5/6 trip unit measurements, trips, and operating

information. It cannot be used to modify the protection settings.

•

Measurements may be easily accessed using a menu.

•

Trips are automatically displayed.

•

A pop-up window displays the time-stamped description of the trip.

Status Indications

When the circuit breaker is equipped with the COM option (BSCM) (including its set of sensors) the

FDM128 display can also be used to view circuit breaker status conditions:

•

O/F: ON/OFF

•

SDE: Fault-trip indication (overload, short-circuit, ground fault)

•

CE, CD, CT cradle management with I/O application module.

Remote Control

When the circuit breaker is equipped with the COM option (BSCM) (including connection to a

communicating motor operator), the FDM128 display can also be used to operate (open/close) the

circuit breaker.

Two operating mode are available:

•

Local mode: open/close commands are enabled from the FDM128 while disabled from the

communication network.

•

Remote mode: open/close commands are disabled from the FDM128 while enabled from the

communication network.
