Status LEDs
|
LED |
Description |
|---|---|
|
Ready LED |
The Ready LED flashes slowly under normal operation. |
|
Status bar |
The Status bar alerts the user to the health state of the circuit breaker:
|
|
ERMS LED |
The ERMS (Energy Reduction Maintenance Setting) LED informs the user when ERMS is engaged, and ERMS protection settings are operational:
|
For more information, see the description of Local Indications.
NFC Communication Zone
The NFC communication zone is used to establish an NFC connection between a smartphone running the EcoStruxure Power Device app and the MicroLogic Active control unit. When the connection is established, the circuit breaker operating data is automatically uploaded to the smartphone.
Display Screen with Navigation Buttons
The local HMI screen and buttons are used to:
-
Navigate the menu structure.
-
Display monitored values.
-
Access and edit configuration settings.
Protection Settings Button
The protection settings button is used to directly access the protection setting procedure.
The protection settings button is protected by a flap which is opened by using a flat screwdriver.
ERMS Button
The ERMS button is used to directly engage and disengage the ERMS function.
The ERMS button is protected by a flap which is opened by using a flat screwdriver.
QR Code
When the QR code on the front face of a MicroLogic Active control unit is scanned with a smartphone running a QR code reader and connected to the Internet, the Go2SE landing page is displayed. The landing page displays some information about the device, including traceability information, and a list of menus.
Control Unit Identification Number
The identification number PPPPPPYYWWDLNNNNLV9••••• is made up as follows:
-
The serial number of the MicroLogic Active control unit in the format PPPPPPYYWWDLNNNN, where the codes are defined as follows:
-
PPPPPP: Plant code
-
YY: Year (00 to 99), for example 24 for 2024
-
WW: Week of the year (01 to 53), for example 25
-
D: Day of the week, with 1 representing Monday and 7 representing Sunday, for example 5
for Friday -
L: Unique manufacturing line code or machine code within the plant
-
NNNN: Unique product number (0001 to 9999) generated on the day of manufacturing, by the plant manufacturing line or the plant machine
-
-
The commercial reference of the control unit in the format LV9•••••
Use the identification number to register your MicroLogic Active control unit through mySchneider app, the customer care mobile application.
Registering your MicroLogic Active control unit enables you to keep your records up to date and enables traceability.
Control Unit Type
The type of MicroLogic Active control unit is indicated by a number and one or two letters:
-
The number (for example, 6.0) defines the type of protection provided by the control unit.
-
The first letter (A or E) defines the type of metering provided by the control unit.
-
If present, a second letter (P) indicates a MicroLogic Active control unit with IEEE 802.15.4 wireless communication.
USB-C Port
Open the cover of the USB-C port to connect the following devices:
-
A Mobile Power Pack to supply power to the MicroLogic Active control unit.
-
An Android smartphone running the EcoStruxure Power Device app through USB OTG connection.
The cover can be sealed to prevent access by unauthorized personnel.
 WARNING |
|---|
|
hazard of electric shock
Do not use MasterPacT MTZ circuit breakers with MicroLogic Active control units:
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
|
Internal Battery
The internal battery powers the trip cause LEDs and the main diagnostic functions in the absence of any other power supply.
For information about testing the internal battery, see Trip Information/Test/Reset Button.
Sensor Plug
The protection ranges depend on the rated current In, defined by the sensor plug present below the MicroLogic Active control unit.
