Closing Function

Closing orders can be sent as follows:

• Directly through a mechanical closing pushbutton.

• Locally through an external closing pushbutton.

• Remotely through a remote order which is managed by the MicroLogic X control unit.

Opening orders have priority over closing orders. No closing orders are taken into account as long as an open order is active.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Do not operate the circuit breaker without confirming that doing so will not create a hazardous situation. Do not allow any person to work on the electrical network without physically validating the successful execution of the local or remote software actions for closing the circuit breaker or switching on the electrical circuit. 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.

The MicroLogic X control unit manages closing orders issued by the following means:

• BPFE connected to MicroLogic X control unit.

• IO module with the Breaker Operation predefined application. Refer to Enerlin'X IO - Input/Output Application Module for One Circuit Breaker - User Guide.

• EcoStruxure Power Commission software.

• EcoStruxure Power Device app through Bluetooth or USB OTG with MasterPacT Operation Assistant Digital Module installed and activated.

• Remote controller connected to the communication network:

  • For communication through Modbus protocol, refer to DOCA0105•• MasterPacT MTZ Circuit Breakers with MicroLogic X Control Units - Modbus Communication - User Guide.

  • For communication through IEC 61850 communication standard, refer to DOCA0162•• MasterPacT MTZ Circuit Breakers with MicroLogic X Control Units - IEC 61850 Communication Guide.

• IFE/EIFE webpages. Refer to the relevant document:

  • Enerlin'X EIFE - Embedded Ethernet Interface for One MasterPacT MTZ Drawout Circuit Breaker - User Guide

  • Enerlin'X IFE - Ethernet Interface for One Circuit Breaker - User Guide

  • Enerlin'X IFE - Ethernet Switchboard Server - User Guide

• FDM121 display connected to the ULP system. Refer to DOCA0088•• Enerlin'X FDM121 - Front Display Module for One Circuit Breaker - User Guide.

• FDM128 display through IFE or EIFE interface. Refer to DOCA0037•• Enerlin'X FDM128 - Ethernet Display for Eight Devices - User Guide.

The closing function is monitored by the MicroLogic X control unit.

The closing function can be inhibited by sending a command through:

• The communication network or EcoStruxure Power Commission software

• The IO module

WARNING
RESTRICTED CLOSING INHIBITION Do not use the inhibit closing order to lock the device in open position. Failure to follow these instructions can result in death, serious injury, or equipment damage.

The inhibit close order inhibits only the closing orders allowed in Auto control mode. The closing orders issued from the mechanical closing pushbutton or BPFE, or from the pushbutton directly connected to the XF voltage release are not inhibited.
