Overview

The maintenance of the MCSeT cubicles relies primarily on its usage, environmental conditions, and its connection to the Schneider Electric cloud.

When the MCSeT cubicles are not connected to the cloud, all maintenance actions occur at fixed periodicity.

When the MCSeT cubicle is connected to the cloud, manufacturer maintenance periodicity becomes condition-based, and allows periodicity extension up to years. Assets under cloud monitoring enable live monitoring, rescheduling the manufacturer maintenance date at the right time for dynamic condition-based maintenance.

The dynamic stage is determined by the Maintenance Index computed in EcoStruxure Asset Advisor.

Preventive Periodic Maintenance

Schneider Electric offers the maintenance in three distinct levels:

Routine maintenance: Simple preventive maintenance is carried out by Schneider Electric experts, service providers, or competent customer technicians.
Intermediate maintenance: Preventive maintenance preferably performed by Schneider Electric specialists or certified, trained service providers (partners, facility managers and so on).
Manufacturer maintenance: Only Schneider Electric experts perform extensive preventive maintenance, which includes ProDiag diagnostics when possible.

NOTE: Intermediate maintenance includes routine maintenance and manufacturer maintenance includes both.

Maintenance Levels and Contents

Maintenance Periodicity

The maintenance plan for non-connected assets follows a time-driven schedule involving routine/intermediate/manufacturer maintenance interventions.

The maintenance periodicity for connected assets, the maintenance frequency follows an optimized and dynamic cycle of intermediate/manufacturer maintenance interventions (refer to Figure 73). By eliminating routine maintenance, it minimizes customer shutdowns.

NOTE: Depending on the customer preference, they can opt for time-based maintenance for connected assets while still receiving maintenance recommendations based on an index for anticipated maintenance.

Maintenance Periodicity for Non-Connected and Connected Assets

NOTE:

Without connected sensors, the manufacturer maintenance periodicity is time-based, for every 3 years.
With connected sensors like C110, TH110 and SEPAM20 installed, the condition monitoring with EcoStruxure Asset Advisor predictive, the manufacturer maintenance periodicity shifts to 5 years.
After the first maintenance operation, the Maintenance Index equals to 1.

If there is unusual changes or changes in usage and environmental conditions, the maintenance index will dynamically increase from 1 to 4, indicating the need to reschedule the next maintenance interval.

Dynamic Condition-Based Maintenance Example (Non-Contractual Picture)

When the intermediate maintenance is performed, the actions for the routine maintenance are also performed.

When the manufacturer maintenance is performed, the intermediate maintenance is also performed.

The maintenance periodicity can be optimized depending on the environmental conditions, and on equipment usage conditions.

Environmental Factors	Normal (all the criteria is to be fulfilled)	Server (from one criterion checked)
Temperature average annual around/out of switchgear	T < 35	T >35
Humidity Relative	H < 85%	H > 85%
Salinity site distance from seaside and room with no protected atmosphere	Low salt mist D > 10 km	High salt mist D < 10 km
Dust level further to filtration and/or ventilation present	Low dust level or filtration and/or ventilation present	High dust level and no filtration and nor ventilation present
Maintenance cycle	T= 3 years	T= 2 years

Manufacturer Maintenance when Connected to the Cloud

If MCSeT product is connected to Schneider Electric cloud, the equipment condition is monitored in live.

The manufacturer maintenance is scheduled depending on the operating conditions.
Maintenance periodicity is condition-based allowing a periodicity extension up to two years.
Dynamic condition-based maintenance is managed by a Maintenance index computed in the Schneider Electric EcoStruxure Asset Advisor cloud. The Manufacturer maintenance interval can be extended to four or five years depending upon the type of Ecostruxure Asset Advisor.
- Preventive: Up to 4 years further to operating/services conditions continuously monitored.
- Predictive: Up to 5 years further to operating/services conditions continuously monitored and asset health computation.

NOTE: Between two consecutive maintenances by manufacturer, the routine and intermediate maintenances must be still required.
