Monitoring the Communicating Voltage Releases

Presentation

The voltage releases undergo wear due to the number of opening or closing operations. It is recommended to check them at periodic intervals to decide whether they must be changed or not. To avoid regular inspection of the communicating voltage releases, events are generated when the communicating voltage releases reach 80% or 100% of the recommended maximum number of operations.

The following communicating voltage releases are monitored by MicroLogic X control unit:

The diagnostic MN undervoltage release (MN diag).
The diagnostic and communicating MX1 opening voltage release (MX1 diag&com).
The diagnostic and communicating MX2 opening voltage release (MX2 diag&com).
The diagnostic and communicating XF closing voltage release (XF diag&com).

NOTE: Standard voltage releases are not monitored by the MicroLogic X control unit.

Operating Principle

The MicroLogic X control unit:

Checks the presence of voltage releases
Counts the number of operations performed by the voltage release
Calculates the percentage of wear of each voltage release
Generates an event when:
- The voltage release reaches 80% of recommended maximum number of operations
- The voltage release reaches 100% of recommended maximum number of operations
Monitors the state of the internal circuit of the voltage release

For more information about the recommended number of operations, refer to DOCA0099•• MasterPacT MTZ - IEC Switch-Disconnectors and Circuit Breakers with MicroLogic X Control Unit - Maintenance Guide.

Resetting the Counters

NOTICE
invalid monitoring After replacement of a communicating voltage release, reset the corresponding operation counter to zero. Failure to follow these instructions will result in incorrect operation count.

The communicating voltage release counters can be reset or set to zero with EcoStruxure Power Commission software (password-protected).

The following voltage release counters can be reset.

MN diag undervoltage release operation counter
MX1 diag&com opening voltage release operation counter
MX2 diag&com opening voltage release operation counter
XF diag&com closing voltage release operation counter

Data Availability

The communicating voltage release data is available as follows:

On the MicroLogic X display screen, at: Home > Maintenance > Health > Actuator wear
With EcoStruxure Power Commission software
With the EcoStruxure Power Device app through Bluetooth or USB OTG connection
On a remote controller using the communication network
