Monitoring the Internal Functioning of the MicroLogic X Control Unit

Presentation

The MicroLogic X control unit carries out a series of self tests to monitor:

Correct internal functioning
Wireless communication
The ULP modules:
- IO modules
- IFE Ethernet interface
- FDM121 display
The presence and state of the internal battery
The presence of the 24 Vdc power supply
The presence of the internal current power supply sensors

Operating Principle

The ready LED, service LED, and trip cause LEDs provide visual information about the health state of the MicroLogic X control unit. The detection of an invalid result in the self tests generates an event (logged in the Diagnostic history) which can be classified as high, medium, or low severity:

Low severity event indicates the detection of an invalid result which has no operational impact. The standard (LSI G/V) protection functions are unaffected.
Medium severity event indicates the detection of an invalid result which has a minor operational impact. The standard (LSI G/V) protection functions are unaffected. A check must be performed at next maintenance.
- The ready LED is flashing
- The service LED is lit in orange if the event requires non-urgent maintenance
- All trip cause LEDs are off
- An orange pop-up screen is displayed
High severity event indicates the detection of an invalid result which can have a major operational impact. The standard (LSI G/V) protection functions can be affected. The control unit must be replaced without delay.
- The ready LED is off
- The service LED is lit in red if the event requires immediate maintenance
- All trip cause LEDs are lit
- A red pop-up screen is displayed

When monitoring of the internal functioning of MicroLogic X control unit detects an invalid result with medium or high severity, an event is generated with an orange or red pop-up screen and corresponding event message.

Data Availability

Monitoring data is available as follows:

With EcoStruxure Power Commission software for all severities
With the EcoStruxure Power Device app through Bluetooth or USB OTG connection for medium and high severities.

Restarting MicroLogic X Control Unit

If the display screen of the MicroLogic X control unit no longer displays menus for protection, alarms, or measures screens, it is recommended to restart the MicroLogic X control unit. The restart is performed through EcoStruxure Power Commission software. It is not necessary to interrupt the power supply to the MicroLogic X control unit during the restart. The settings of the MicroLogic X control unit are not affected by the restart. The standard protection functions remain active during the restart.

Contact Schneider Electric Support or your Schneider Electric Services representative for more information about who can carry out the recommended actions.

Display Screen Replacement

The display screen can be replaced. Always replace the display screen with one that corresponds to the control unit type (MicroLogic X with wireless communication or MicroLogic Xi without wireless communication).

For information about display screen replacement, consult the instruction sheets on the Schneider Electric website:

NHA49910: replacement of the MicroLogic X display screen (commercial reference LV850054SP)
GDE66729: replacement of the MicroLogic Xi display screen (commercial reference LV850054WWSP)

Replacing the display screen of a MicroLogic X control unit with a MicroLogic Xi display screen (and vice versa) generates the event Discrepancy between display and MicroLogic. This discrepancy has no impact on the protections provided by the control unit. The control unit is operational.

Nonetheless, the control unit operation is limited as follows:

The Quick View screens are displayed in English.
Only the standard protection functions of the control unit in the Protection menu can be read and set. They are available only in English.

The other menus cannot be accessed and control unit firmware update is not possible.

NOTE: For more information about MicroLogic Xi control unit, refer to the appendix.

Internal Battery Replacement

The internal battery of the MicroLogic X control unit can be replaced on site when discharged. The replacement can be made with the circuit breaker in the open or closed position, and the control unit supplied with power. A test of the internal battery must be carried out immediately after the replacement of the internal battery to check the correct functioning of the new battery.

For information about internal battery replacement and installation, consult the instruction sheet on the Schneider Electric website: NHA57283
