Masterpact MTZ1 Control Modes

The control mode of the Micrologic X control unit sets how the opening and closing functions of the circuit breaker are controlled.

Two control modes are available: Manual and Auto.

Manual mode only accepts orders made using one of the following:

The mechanical buttons on the front of the circuit breaker.
The external pushbutton connected to the undervoltage release (MN)/shunt trip (MX)/shunt close (XF).
The electrical closing pushbutton (BPFE).

Auto mode has two settings: Local or Remote. All orders accepted in manual mode are accepted in auto mode, as well as orders from local or remote communication as follows:

Auto Local: the operator needs to be close to the circuit breaker to establish communication and only orders sent from a local source through communication are accepted:
- Ecoreach software through the USB connection.
- Masterpact MTZ Mobile App through Bluetooth with the Masterpact Operation Assistant Digital Module.
Auto Remote: the operator does not need to be next to the circuit breaker to establish communication and orders are only accepted sent from a remote source through the communication network.

NOTE: Ecoreach software connected through the communication network can be used to send control orders to the circuit breaker.

The control mode factory setting is Auto Remote.

Setting the Micrologic X Control Mode

The Auto or Manual mode can be set as follows:

On the Micrologic X display screen, at Home → Configuration → Communication → Control Mode → Mode.
With the Masterpact MTZ Mobile App through Bluetooth or USB OTG connection.

The Local or Remote mode can be set as follows:

When the IO module is used with the Breaker Operation predefined application, the local or remote mode is defined only by the control mode selector switch wired to the digital input I1 of the IO module.
When the IO module is not used with the Breaker Operation predefined application, the local or remote mode can be set as follows:
- With Ecoreach software through a USB connection.
- With the Masterpact MTZ Mobile App through Bluetooth or a USB OTG connection.

NOTE:

The Local or Remote mode cannot be set on the Micrologic X display screen.
When Auto mode is set, the control mode is Auto Local or Auto Remote, depending on the last setting.

Displaying the Micrologic X Control Mode

The control mode (Manual, Auto Local, or Auto Remote) is displayed as follows:

On the Micrologic X display screen, at Home → Configuration → Communication → Control Mode → Mode.
With Ecoreach software through the USB connection.
With the Masterpact MTZ Mobile App through Bluetooth or the USB OTG connection.
On the IFE/EIFE webpages.
By a remote controller using the communication network.

Micrologic X Control Mode Predefined Events

Changing the control mode settings generates the following events:

Event	History	Severity
