Closing Masterpact MTZ Devices

Conditions Required to Close

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.

To close the device, the following conditions must be met:

  • Device is open (O).

  • Closing spring is charged.

  • The device is ready to close, OK is displayed.

NOTE: An opening order always takes priority over a closing order. The device cannot be closed while an opening order is being received. If OK is crossed-out on the ready-to-close indicator, an order to open is being received (either electrically or mechanically) and must be ended before OK can be displayed.

Closing the Masterpact MTZ2/MTZ3 Mechanism

The following tables present the different ways to close the device in the different control modes available.

The device can be closed in the following ways in all control modes:

Closing Type

Control Mode

Accessories

Closing Action

Mechanical

Manual, Auto: Local, or Auto: Remote

Press the closing pushbutton on the front of the device.

This closing action is possible when the closing conditions are met.

Electrical with BPFE

Manual, Auto: Local, or Auto Remote

  • Electrical closing pushbutton (BPFE)

  • Communicating shunt close (XF)

Press the electrical closing pushbutton (BPFE), mounted on the front cover.

The closing action takes into account internal closing conditions of the device and the external conditions that are part of the control and monitoring system of the installation.

External pushbutton

Manual, Auto: Local, or Auto: Remote

  • External pushbutton wired by customer

  • Standard (XF) or communicating shunt close (XF diag&com)

  • Spring charging motor (MCH)

Press the external pushbutton, which is connected to the XF shunt close through the customer terminal block.

In addition, the device can be closed in the following ways when Auto control mode is configured.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
  • Before working on or inside equipment, turn off all power supplying the equipment manually or using the local or remote software for opening the circuit breaker or switching off the electrical circuit.
  • Always use a properly rated voltage sensing device to confirm power is off.
Failure to follow these instructions will result in death or serious injury.

Closing Type

Control Mode

Accessories

Closing Action

Through IO module

Auto: Local
or Auto: Remote

Communicating shunt close (XF com&diag)

Spring charging motor ((MCH)

ULP port module

IO module

Close the device using the predefined application 2 Breaker Operation of the IO module.

  • When the device is set to local control mode by the IO module, the command to close is issued from local pushbuttons wired on digital inputs.

  • When the device is set to remote control mode by the IO module, the command to close is issued from remote PLC outputs wired on digital inputs.

Refer to Enerlin’X IO Input/Output Application Module for One Circuit Breaker - User Guide (0613IB1317).

Spring charging motor (MCH)

ULP port module

IO module

Through Ecoreach software

Auto: Local

Communicating shunt close (XF com&diag)

Send a command to close to the device from Ecoreach software running on a PC connected locally to the device through the mini USB port on the Micrologic X control unit.

The closing action is password-protected.

Refer to Ecoreach Online Help (DOCA0069EN).

Spring charging motor (MCH)

Through Masterpact MTZ Mobile App

Auto: Local

Communicating shunt close (XF diag&com)

Send a command to close to the device from the Masterpact MTZ Mobile App with Masterpact Operation Assistant Digital Module, through Bluetooth wireless communication or USB OTG connection. The closing action is password protected.

Spring charging motor (MCH)

Masterpact Operation Assistant Digital Module

Through communication

Auto: Remote

Communicating shunt close (XF diag&com)

Send a command to close to the device through the communication network.

This closing action is password-protected.

Refer to Masterpact MTZ - Modbus Communication Guide (OCA0105EN).

NOTE: Ecoreach software running on a PC connected to the device through the communication network can be used to send commands to close.

Spring charging motor (MCH)

ULP port module

Communication interface

Through IFE/EIFE webpages

Auto: Remote

Communicating shunt close (XF diag&com)

Send a command to close to the device from the IFE/EIFE control webpage.

This closing action is password-protected.

Refer to:

Spring charging motor (MCH)

ULP port module

Communication interface

If the device does not close, refer to Troubleshooting.

Inhibiting the Masterpact MTZ2/MTZ3 Closing Function

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

  • The communication network through Ethernet Modbus/TCP.

  • 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 shunt close are not inhibited.
