Micrologic X Status LEDs

LED

Description

Ready

The Ready LED flashes when the control unit is ready to provide standard protection.

The service LED indicates the overall health of the circuit breaker:

  • Unlit LED: the circuit breaker is in good working order

  • Orange LED: non-urgent alert message

  • Red LED: alert message that requires immediate action

ERMS

The ERMS (Energy Reduction Maintenance Setting) LED has the following statuses:.

  • Blue LED: ERMS engaged

  • Off LED: ERMS disengaged

Local HMI Display Screen with Contextual and Dedicated Buttons

Use the local HMI screen and buttons to:

  • Navigate the menu structure

  • Display monitored values

  • Access and edit configuration settings

NFC Communication Zone

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.

Bluetooth Activation Button and LED

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.

Micrologic X Control Unit Test Button

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

Micrologic X Control Unit Test/Reset Button

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.

NOTE: When the Micrologic X control unit is not powered by an external 24 Vdc power supply or through a USB connection, the Micrologic X control unit can be restarted by pressing and holding the Test/Reset button for 15 seconds. The standard protection functions remain active during the restart.

Micrologic X Control Unit Mini USB Port

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.

NOTE: The Micrologic X control unit does not support USB keys. Even if a USB key is connected using an adaptor, data is not transferred.

Micrologic X Control Unit Overload and Trip Cause LEDs

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

NOTE: If the Micrologic X control unit is not powered, the trip cause LEDs go off after four hours. After this period, press the Test/Reset button to light them again.

Micrologic X Internal Battery

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

Micrologic X VPS Voltage Power Supply Module

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

Micrologic Control Unit QR Code

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.

Micrologic X Control Unit Identification Number

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.

Micrologic X Control Unit Type

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.

Micrologic X Sensor Plug

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