Device View for Circuit Breakers and Switch-Disconnectors

Overview

For each submenu selected in the left tab of the main area, a headpiece allows you to navigate through the tabs. Press the corresponding tab title to display it.

Data displayed in the Device view screen depends on the type of device. For circuit breakers, it depends also on the type of MicroLogic trip unit installed. Refer to the relevant MicroLogic user guides provided in the section Related Documents.

The table lists the features available per device type:

Measurement Display Modes

Measurements can be displayed in the following modes:

• Numeric

• Bargraph

• Dial

To switch between modes, press the icon at the bottom-right of the screen.

To read the voltage bar graph correctly, you must set up the primary nominal voltage of the circuit breaker.

Quick View

The Quick view submenu displays the status and main measurements, and protection settings (long time, short time, instantaneous, ground fault, or earth leakage) from a single circuit breaker.

There is no tab in this submenu.

Measures

The Measures submenu displays measurements from a single circuit breaker.

The tabs are the following:

• I

• V

• PQS

• E

• F-PF-Cosϕ

• THD

In tabs where the maximum measurement can be reset, you can reset the measurements when the remote control is enabled (IFM or IFE locking pad points to the open padlock, or the EIFE intrusive commands mode is unlocked). In these conditions, press the Reset button to access the RESET screen, where:

• Pressing resets the measurements on the previous screen.

• Pressing resets the maximum values, minimum values, and energy counters of the circuit breaker.

Alarm History

The Alarm history submenu gives access to the various histories of the circuit breaker.

The table presents the description and number of records of each history according to the circuit breaker.

Each record is summarized by three elements:

• Date and time of event occurrence and completion

• Designation

• Code

Control

DANGER
RISK OF ELECTROCUTION, ELECTRIC ARC, OR BURNS Check that the downstream electrical equipment is safe. Check that you control the appropriate circuit breaker. Failure to follow these instructions will result in death or serious injury.

WARNING
HAZARD OF CLOSING ON ELECTRICAL FAULT Do not close the circuit breaker again without first inspecting and, if necessary, repairing the downstream electrical equipment. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Before controlling a circuit breaker, you have to:

• Verify that you are logged as an administrator. The control functions can be accessed only when you are logged in as an administrator.

• Verify that MasterPacT MTZ circuit breakers are equipped with MX and XF communicating voltage releases.

• Verify that MasterPacT NT/NW, ComPacT NS , or PowerPacT P- and R-frame circuit breakers are equipped with a BCM ULP, MX, and XF communicating voltage releases or a communicating motor mechanism.

• Verify that ComPacT NSX or PowerPacT H-, J-, or L-frame circuit breakers are equipped with a BSCM or BSCM MBSL and a communicating motor mechanism in automatic mode.

• Verify that the circuit breaker is in remote control mode.

• Verify that you know the circuit breaker password. The password of the circuit breaker is set using the EcoStruxure Power Commission software.

• Verify that the IFE or IFM locking pad points to the unlocked position, when the circuit breaker is connected to an IFE or IFM interface.

• Verify that the intrusive command mode is unlocked, when the circuit breaker is connected to an EIFE interface.

The Control submenu allows you to check the status and to execute actions remotely to operate the circuit breaker.

The table presents the possible actions depending on the circuit breaker:

The FDM128 display takes you through the following sequence:

Maintenance

The table presents the functions of each tab of the Maintenance submenu:

I/O1 and I/O2

For each connected I/O module, the I/O1 and I/O2 submenus allow you to:

• Check the status of its inputs

• Control its outputs

• Read its pulse counters

Before controlling an I/O module output, you have to:

• Verify that the output of the I/O module is assigned using EcoStruxure Power Commission software.

• Verify that you know the I/O module password. The password of the I/O module is set using EcoStruxure Power Commission software.

• Verify that the I/O module locking pad points to the unlocked position.

• Verify that the IFE or IFM locking pad points to the unlocked position when the I/O module is connected to an IFE or IFM interface.

• Verify that the intrusive command mode is unlocked when the I/O module is connected to an EIFE interface.

The Control submenu allows you to check the status and to execute actions remotely to actuate the I/O module output.

The possible actions are to open or close the output.

The FDM128 display takes you through the following sequence:
