Maintenance Schedule

Presentation

The MicroLogic X control unit provides information to help with scheduling preventive maintenance operations.

It monitors maintenance programs performed and generates events to indicate that maintenance is due.

For more information about maintenance programs and maintenance frequency, refer to DOCA0099•• MasterPacT MTZ - IEC Switch-Disconnectors and Circuit Breakers with MicroLogic X Control Unit - Maintenance Guide.

Operating Principle

The MicroLogic X control unit generates events to inform the user that maintenance needs to be planned.

A maintenance schedule event is completed when the date of the maintenance program performed is declared by using EcoStruxure Power Commission.

The manufacturer maintenance schedule for maintenance operations depends on:

The operating and environmental conditions of the MasterPacT MTZ circuit breaker.
The criticality of the user application.
The date of the last maintenance program performed, and declared by using EcoStruxure Power Commission software.

Basic and standard end-user maintenance schedule events and Manufacturer maintenance schedule events are calculated:

For the first event:
- From the commissioning date of the circuit breaker, if this date is declared by using EcoStruxure Power Commission software.
- Otherwise from the assembly date of the circuit breaker.
For subsequent events, from the date of the previous maintenance program (Basic, Standard, or Manufacturer) performed, if the date is declared by using EcoStruxure Power Commission software.

NOTE: Subsequent Manufacturer maintenance schedule events are calculated from the previous Manufacturer maintenance program performed and declared by using EcoStruxure Power Commission software.

If the date of the maintenance program performed is not declared by using EcoStruxure Power Commission software, the MicroLogic X control unit continues to use the commissioning date or assembly date to calculate the maintenance schedule events.

Maintenance Programs

The following table summarizes maintenance operations for the three preventive maintenance programs:

Maintenance program	Maintenance description	Performed by
Basic end-user maintenance	Visual inspection and functional testing, replacement of inoperative accessories.	Trained and qualified end-user personnel Trained and qualified maintenance services provider personnel Schneider Electric Services representative
Standard end-user maintenance	Basic end-user maintenance, plus operational servicing and subassembly tests.	Trained and qualified maintenance services provider personnel Schneider Electric Services representative
Manufacturer maintenance	Standard end-user maintenance, plus diagnostics and part replacements by Schneider Electric Services.	Schneider Electric Services representative

NOTE: Global service plans delivered by Schneider Electric may include maintenance plans for your equipment, with a different wording for maintenance levels:

Basic end-user maintenance in this guide corresponds to Routine maintenance in service plans and in maintenance guides for MasterPacT MTZ circuit breakers with MicroLogic X control unit.
Standard end-user maintenance in this guide corresponds to Intermediate maintenance in service plans and in maintenance guides for MasterPacT MTZ circuit breakers with MicroLogic X control unit.
Manufacturer maintenance remains the same.

Maintenance Frequency

The manufacturer maintenance frequency is determined from the following recorded parameters and declared settings.

The following parameters for environmental conditions are recorded by the MicroLogic X control unit:

Temperature
Percent load
Harmonics
Relative humidity
Vibration

The following settings for environmental conditions and user application criticality are declared by using EcoStruxure Power Commission software (password-protected).

Setting		Value	Factory setting
Environmental conditions	Corrosive atmosphere	3C1 (Rural area) 3C2 (Urban area) 3C3 (Immediate vicinity of industrial pollution) 3C4 (Inside polluting industrial premises)	3C2
	Salt environment	None (No salt mist) Moderate (Salt mist < 10 km (6.5 mi) from seaside) Significant (Salt mist < 1 km (0.65 mi) from seaside)	None
	Dust	Low level Moderate level High level	Low level
User application criticality		Low Moderate High	Low

Recording Data of Maintenance Programs Performed

NOTICE
INCORRECT MAINTENANCE SCHEDULE The date of the maintenance program performed must be declared by using EcoStruxure Power Commission software. Failure to follow these instructions will result in invalid maintenance schedule.

After performing a preventive maintenance program, maintenance personnel must declare the following data by using EcoStruxure Power Commission software:

Maintenance program performed: Basic, Standard, Manufacturer
Date of maintenance operation
Name of service provider
Name of maintenance personnel

Data Availability

Maintenance schedule data is as follows:

Data of the last maintenance program performed, if the data is declared by using EcoStruxure Power Commission software:
- Program performed: Basic, Standard, or Manufacturer
- Date of maintenance operation
- Name of service provider
- Name of maintenance personnel
Data of the next maintenance program to be performed:
- Program to be performed: Basic, Standard, or Manufacturer
- Either the number of months before the program is due or the number of months it is overdue

Maintenance schedule data is available as follows:

On the MicroLogic X display screen at: Home > Maintenance > Assistance > Maint.schedule
With EcoStruxure Power Commission software
With EcoStruxure Power Device app through Bluetooth or USB OTG connection
On a remote controller using the communication network

Predefined Events

The maintenance schedule function generates the following events:

Code	Event	History	Severity
0x1480 (5248)	Schedule basic maintenance within one month	Diagnostic	Medium⁽¹⁾
0x1481 (5249)	Schedule standard maintenance within one month	Diagnostic	Medium⁽²⁾
0x1482 (5250)	Schedule manufacturer maintenance within three months	Diagnostic	Medium⁽²⁾
(1) Disabled by default. Customizable with EcoStruxure Power Commission software. (2) Enabled by default, with pop-up messages.

Recommended Actions

Code	Event	Recommended actions
0x1480 (5248)	Schedule basic maintenance within one month	Plan to schedule the basic preventive maintenance program within one month.
0x1481 (5249)	Schedule standard maintenance within one month	Plan to schedule the standard preventive maintenance program within one month.
0x1482 (5250)	Schedule manufacturer maintenance within three months	Plan to schedule the manufacturer preventive maintenance program within three months.

For information about the preventive maintenance programs, refer to DOCA0099•• MasterPacT MTZ - IEC Switch-Disconnectors and Circuit Breakers with MicroLogic X Control Unit - Maintenance Guide.
