Automatic Preventive Maintenance for Equipment (or any other assets) can be managed by using Events.
An Event consists of one or more Actions and one or more Triggers.

Preventive Maintenance
The care and servicing by personnel for the purpose of maintaining equipment and facilities in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects. Preventive maintenance can be simply described as maintenance of equipment or systems before a fault occurs. It can be divided into two subgroups:
- Planned/Scheduled Maintenance
- Condition-Based Maintenance
The main difference between the two subgroups is determination of maintenance time, or determination of moment when maintenance should be performed.
While preventive maintenance is generally considered to be worthwhile, there are risks such as equipment failure or human error involved when performing preventive maintenance, just as in any maintenance operation. Preventive maintenance as scheduled overhaul or scheduled replacement provides two of the three proactive failure management policies available to the maintenance engineer. Common methods of determining what Preventive (or other) failure management policies should be applied are; OEM recommendations, requirements of codes and legislation within a jurisdiction, what an "expert" thinks ought to be done, or the maintenance that's already done to similar equipment, and most important measured values and performance indications.
To make it simple:
Preventive maintenance is conducted to keep equipment working and/or extend the life of the equipment.
Corrective maintenance, sometimes called "repair," is conducted to get equipment working again.
The primary goal of maintenance is to avoid or mitigate the consequences of failure of equipment. This may be by preventing the failure before it actually occurs which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Preventive maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause complete system failure and unscheduled down time. The ideal preventive maintenance program would prevent all equipment failure before it occurs.
Preventive and Predictive Maintenance
See the examples below for a basic outline of the differences between Preventive and Predictive Maintenance:
Preventive Maintenance
You use incandescent light bulbs. The manufacturing company tellls you that the life span of the bulb is 3 years. So just before 3 years of use you have decided to replace the bulb with a new one and scheduled it for a maintenance.
Predictive Maintenance
Everyday you have the opportunity to observe the bulb operation. After just two years of use, the bulb starts flickering. So you are predicting at that time that the bulb is going to fail very soon and have decided to change it for a new one and scheduled a just-in time maintenance.
