Micrologic X Control Unit Description

Use the local HMI screen and buttons to:

• Navigate the menu structure

• Display monitored values

• Access and edit configuration settings

Use the NFC communication zone to create an NFC connection between a smartphone running the Masterpact MTZ Mobile App and the Micrologic X control unit. When the connection is established, the circuit breaker operating data is automatically uploaded to the smartphone.

Use the Bluetooth activation button to create a Bluetooth low-energy connection between a smartphone running the Masterpact MTZ Mobile App and the Micrologic X control unit. When the connection is established, the circuit breaker can be monitored and controlled from the smartphone.

The Bluetooth LED blinking indicates that a Bluetooth device is in communication.

Use the test button to test the ground-fault protection for Micrologic 6.0 X control units.

The Test/Reset button performs the following functions:

• Test internal battery or check LED functionality: press and hold the Test/Reset button for less than three seconds, the four trip cause LEDs switch off for one second. One of the following results:

  • The four trip cause LEDs switch on for two seconds: the battery is OK.

  • The four trip cause LEDs flash sequentially for two seconds: the battery is near the end of its life. Replace the battery.

  • The four trip cause LEDs do not light: replace the battery.

• Reset: press and hold the Test/Reset button for more than three seconds to reset the control unit. The trip cause LEDs and the service LED switch off.

Remove the rubber cover of the mini USB port to connect the following devices:

• A Mobile Power Pack to supply power to the Micrologic X control unit.

• A smartphone running the Masterpact MTZ Mobile App through USB OTG connection.

• A PC equipped with Ecoreach software.

The indications of the four trip cause LEDs depend on the type of control unit.

LEDs	Description
	Micrologic 3.0 X, 5.0 X, 6.0 X: Overload pre-alarm, the load exceeds 90% and is lower than 105% of the Ir setting of the long-time protection.
	Micrologic 3.0 X, 5.0 X, 6.0 X: Overload alarm, the load exceeds 105% of the Ir setting of the long-time protection.
	Micrologic 3.0 X, 5.0 X, 6.0 X: Trip due to long-time protection.
	Micrologic 3.0 X: Trip due to instantaneous protection.
	Micrologic 5.0 X, 6.0 X: Trip due to short-time protection or instantaneous protection.
	Micrologic 3.0 X, 5.0 X: Not used. Micrologic 6.0 X: Trip due to ground-fault protection.
	Micrologic 3.0 X, 5.0 X, 6.0 X: Trip due to other protection (optional protections activated via digital modules).
	Micrologic 3.0 X, 5.0 X, 6.0 X: Invalid Micrologic control unit self-test

The internal battery powers the trip cause LEDs and the main diagnostic functions in the absence of any other power supply.

The optional VPS power supply module provides an internal voltage supply to the Micrologic X control unit.

When the QR code on the front face of a Micrologic X control unit is read with a smartphone running a QR code reader and connected to the internet, the Go2SE landing page is displayed (seeGo2SE Landing Page). The landing page displays information about the device and a list of menus.

The identification number consists of:

• The serial number of the Micrologic X control unit in the format FFFFFFYYWWDXXXXX.

• The commercial reference of the control unit in the format LV8XXXX.

Use the identification number to register the Micrologic X control unit.

Registering the Micrologic X control unit enables up-to-date record keeping and traceability.

This code indicates the type of Micrologic control unit:

• The number (for example, 3.0) defines the types of protection provided by the control unit.

• The letter (X) identifies the range.

The protection ranges depend on the rated current In, defined by the sensor plug present below the Micrologic X control unit.
