MicroLogic X control units receive and process electrical opening orders. An event is generated on opening.
Opening orders can be sent as follows:
oDirectly through a mechanical opening pushbutton.
oLocally through an external opening 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.
The open orders on MN or MX voltage releases by external pushbutton can be maintained to force the circuit breaker in open position and reject any close order. The MicroLogic X open orders are not maintained.
Management of Opening 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 opening the circuit breaker or switching off the electrical circuit. |
|
Failure to follow these instructions will result in death or serious injury. |
The MicroLogic X control unit manages opening orders issued by the following means:
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 opening function is monitored by the MicroLogic X control unit.
