Preventive Maintenance processes

Preventive maintenance ensures that equipment remains in optimal working condition by performing maintenance tasks at regular intervals or based on specific condition triggers. This guide explains how preventive maintenance is driven by preventive plans, which include time cycles and measuring points to automatically generate maintenance orders.

Preventive Plans

A preventive plan is a set of rules that determine when and how preventive maintenance should be performed on equipment. Each preventive plan can be associated with one or more pieces of equipment and contains triggers for maintenance order generation based on time cycles and/or measuring point values.

Time Cycle

Time cycles define the frequency and scheduling of preventive maintenance tasks. The plan specifies how often maintenance should occur and how far in advance maintenance orders should be created. Here's how it works:

• Frequency: Defines how often preventive maintenance should be performed (e.g., monthly).

• Lead Time: Specifies how many days in advance the maintenance order should be created to allow for planning (e.g., 7 days before the maintenance date).

Example: If preventive maintenance is scheduled for the 15th of every month, the maintenance order will be automatically generated on the 8th of the month.

If the preventive maintenance order is completed earlier or later than scheduled, the Shift Factor is applied. The Shift Factor adjusts the scheduling of subsequent maintenance orders by the number of days the previous order was shifted, ensuring the interval between maintenance tasks remains consistent.

Measuring Points

Measuring points are specific values or conditions monitored on equipment, such as temperature or operating cycles. Preventive plans can include specific breakpoints or trigger points for these measuring values.

• Trigger Points: Conditions set in the preventive plan that generate a maintenance order when met (e.g., temperature reaches 90°C).

• Shift Factor: Adjusts the timing of existing or future maintenance orders based on the triggered event, ensuring the maintenance interval remains consistent.

Example: If a temperature measuring point reaches 90°C, a new preventive maintenance order is generated. If an order already exists and is not yet in process, its timing is adjusted to the current time, and the Shift Factor is applied to subsequent orders.

Step-by-Step Guide to Preventive Maintenance Process

1. Create a Preventive Plan:

   • Navigate to the Preventive Plan Parametrization section in the software.

   • Create a new preventive plan and define the time cycle and/or measuring points.

2. Allocate Equipment:

   • Assign the preventive plan to one or more pieces of equipment.

   • Ensure that each piece of equipment has the relevant measuring points set up.

3. Define Time Cycle Rules:

   • Specify the frequency (e.g., monthly) and lead time (e.g., 7 days) for maintenance orders.

   • Save the plan to activate the time cycle triggers.

4. Set Measuring Points and Trigger Points:

   • Define the measuring points (e.g., temperature, operating cycles) for the equipment.

   • Set the trigger points (e.g., temperature ≥ 90°C) in the preventive plan.

   • Save the plan to activate the measuring point triggers.

5. Automatic Maintenance Order Generation:

   • The system automatically generates maintenance orders based on the defined time cycle.

   • If a trigger point condition is met, a new order is generated, or the timing of an existing order is adjusted using the Shift Factor.

6. Manage Shift Factor Adjustments:

   • If a preventive maintenance order is completed earlier or later than scheduled, the Shift Factor is applied.

   • This ensures that all subsequent orders are shifted by the same number of days, maintaining the original interval between maintenance tasks.

Tips for Effective Preventive Maintenance

• Regular Review: Periodically review preventive plans and update them as necessary to reflect changes in equipment conditions or maintenance requirements.

• Monitor Measuring Points: Ensure that measuring points are accurately tracked and trigger points are appropriately set to avoid unnecessary or missed maintenance.

• Utilize Reports: Use reporting features to analyze the effectiveness of preventive maintenance plans and make data-driven adjustments.

Conclusion

Implementing a well-structured preventive maintenance process is crucial for minimizing equipment downtime and extending the lifespan of machinery. By leveraging time cycles and measuring points within preventive plans, you can automate maintenance tasks and ensure timely interventions.
