Monitoring the Internal Functioning of the MicroLogic Active Control Unit
Presentation
The MicroLogic Active control unit carries out a series of self tests to monitor:
-
Correct internal functioning
-
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
-
The temperature inside the control unit
Operating Principle
The Ready LED, Status bar, and trip cause LEDs provide visual information about the health state of the MicroLogic Active 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 (LSIG) protection functions are unaffected.
-
Medium severity event indicates the detection of an invalid result which has a minor operational impact. The standard (LSIG) protection functions are unaffected. A check must be performed at next maintenance.
-
The Ready LED is flashing
-
The Status bar 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 (LSIG) protection functions can be affected. The control unit must be replaced without delay.
-
The Ready LED is off
-
The Status bar 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 Active 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.
Setting Change Not Applied
The MicroLogic Active control unit monitors progress when protection settings are changed, and generates the Last protection settings have not been applied event if the new protection settings are unable to be applied.
Data Availability
Monitoring data is available as follows:
-
On the MicroLogic Active display screen.
-
With EcoStruxure Power Commission software for all severities
-
With EcoStruxure Power Device app through USB OTG connection for medium and high severities.
-
With the IEEE 802.15.4 wireless communication network for MicroLogic Active AP/EP control units.

Internal Battery Replacement
The internal battery of the MicroLogic Active 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: PKR4244002MicroLogic Active - Spare Battery - Instruction Sheet
