How to Maintain MicroLogic XMicroLogicMicroLogic Active Control Unit

Functions

The control unit permanently monitors the electrical network and generates trip orders when electrical faults are detected.

Electronic component qualification data is usually quoted for a 10-year lifetime by the component suppliers according to the device mission profile. The control unit can operate more than 10 years, depending on the operating environmental conditions (for example, temperature, humidity, vibrations, mechanical shocks, corrosive atmosphere).

Schneider Electric recommends that the Schneider Electric Services representative replaces the MicroLogic X control unit and associated optional ESM or M2C modules every 15 years. Each time the MicroLogic X control unit is replaced, the performer, the rating plug, and the sensor plug must be replaced by the Schneider Electric Services representative.

Firmware Update Policy

The MicroLogic X control unit is the main component of the intelligent modular unit (IMU).

The primary reason for updating the firmware of a MicroLogic X control unit is to obtain the latest IMU features. If the latest IMU features are not required, it is not mandatory to update the firmware of the MicroLogic X control unit and the Enerlin’X devices of the IMU.

Use the latest version of EcoStruxure Power Commission software to update the firmware of the MicroLogic X control unit or an Enerlin’X device of the IMU.

After updating the firmware of one device, Schneider Electric recommends that you update the firmware of the other devices in the IMU to keep consistency and avoid discrepancies between devices. Before proceeding, check the compatibility of the other devices with the new firmware.

For more information about firmware update policy, refer to MicroLogic Trip Units and Control Units - Firmware History.
