MicroLogic X control units receive and process electrical closing orders. An event is generated on closure.
Closing orders can be sent as follows:
oDirectly through a mechanical closing pushbutton.
oLocally through an external closing pushbutton.
oRemotely 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.
NOTE: The BPFE electrical closing pushbutton can be connected to MicroLogic X control unit, as shown in the preceding diagram. In this case the control unit manages the closing function and the closing orders from the BPFE. The BPFE closing order is available in both Manual and Auto control modes.
Alternatively, the BPFE electrical closing pushbutton can be connected to the XF communicating closing voltage release, as shown in the following diagram. In this case the MicroLogic X control unit does not manage the closing function and only closing orders in Manual mode are valid.
Management of Closing Function
|
|
|
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH |
|
oDo not operate the circuit breaker without confirming that doing so will not create a hazardous situation. oDo 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. |
|
|
|
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:
oBPFE connected to MicroLogic X control unit.
oIO module with the Breaker Operation predefined application. Refer to Enerlin'X IO - Input/Output Application Module for One Circuit Breaker - User Guide.
oEcoStruxure Power Commission software.
oEcoStruxure Power Device app through Bluetooth or USB OTG with MasterPact Operation Assistant Digital Module installed and activated.
oRemote controller connected to the communication network:
oFor communication through Modbus protocol, refer to DOCA0105EN MasterPact MTZ - Modbus Communication Guide
oFor communication through IEC 61850 communication standard, refer to DOCA0162EN MasterPact MTZ - IEC 61850 Communication Guide
oIFE/EIFE webpages. Refer to the relevant document:
oEnerlin'X EIFE - Embedded Ethernet Interface for One MasterPact MTZ Drawout Circuit Breaker - User Guide
oEnerlin'X IFE - Ethernet Interface for One IEC Circuit Breaker - User Guide
oEnerlin'X IFE - Ethernet Switchboard Server - User Guide
oFDM128 display through IFE or EIFE interface. Refer to DOCA0037EN Enerlin’X FDM128 - Ethernet Display for Eight Devices - User Guide.
The closing function is monitored by the MicroLogic X control unit.

Inhibiting the Closing Function
The closing function can be inhibited by sending a command through:
oThe communication network or EcoStruxure Power Commission software
oThe IO module
NOTE: Using EcoStruxure Power Commission software, you can determine whether the closing inhibition can be controlled by using the IO module, or not.
|
IO Inhibit close |
Inhibit close order from IO module with the Breaker Operation predefined application (I4) |
|
Breaker Closing Inhibition enabled |
A setting of the MicroLogic X control unit, set by using EcoStruxure Power Commission software, enabling control of closing inhibition through IO module. |
|
COM inhibit close |
Inhibit close order from a remote controller using the communication network or from EcoStruxure Power Commission software |
|
COM enable close |
Enable close order from a remote controller using the communication network or from EcoStruxure Power Commission software |
|
Inhibit close |
Close orders allowed in Auto control mode are inhibited (1) or enabled (0) |
|
|
|
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.
The function generates the following predefined events:
