Move beyond fixed schedules and automate maintenance tasks based on real-time asset condition. Learn how to set up triggers that improve efficiency, reduce costs, and prevent breakdowns.
Condition based triggers are the engine of predictive maintenance, turning data from sensors and inspections into automated, actionable work orders.
Condition based triggers are automated rules that create a work order or a maintenance alert when a specific condition is met, such as an engine temperature exceeding a threshold or a diagnostic fault code being logged.
This process replaces traditional time- or mileage-based maintenance with a data-driven approach. Instead of changing oil every 10,000 miles, a trigger might initiate a change when oil analysis shows a critical level of contaminants. This is the core of predictive maintenance and works with other systems like AI anomaly detection and failure modes analysis to provide a complete picture of asset health.
| Trigger Source | Action Initiated | Benefit |
|---|---|---|
| Diagnostic Fault Code (DTC) | Immediate work order for repair | Avoids Engine Shutdown |
| High Engine Temperature | Alert for coolant system inspection | Prevents Overheating |
| High Vibration Reading | Work order for bearing/driveline check | Avoids Catastrophic Failure |
| Oil Analysis Flag | Alert for oil/filter change | Optimizes Fluid Intervals |
| Low Battery Voltage | Alert for battery health check | Prevents Dead Batteries |
A robust condition based trigger system is built on three pillars: data collection, rule setting, and automated response.
Condition based triggers are the foundation of a modern, efficient maintenance program. They are most effective when they are fully integrated with your overall predictive maintenance strategy.
By setting up triggers, you can automate critical processes that were once manual. For example, a trigger can be set for low DEF levels to schedule a service, linking your emissions-def program to a work order system. Similarly, you can create triggers based on data from your tire health monitoring to schedule rotations or replacements when tire pressure drops below a certain point. This automation frees up your team to focus on high-value tasks.
Reduction in maintenance labor hours through automation
Increase in asset uptime by preventing unplanned breakdowns
Decrease in maintenance costs by eliminating unnecessary service
Shift from reactive to proactive maintenance
When oil analysis shows a contaminant level of 25 parts per million (PPM), an automated work order is created to schedule a fluid sample and inspection to confirm the source of contamination.
When a vibration sensor on a wheel end detects a reading above the "warning" threshold, a trigger is set to alert a technician and create a work order for a visual inspection of the wheel bearing at the next available service window.
If a telematics system logs a battery voltage below 12.0V for more than 5 minutes while the engine is off, a trigger creates an alert for the maintenance manager to inspect the battery's health and charging system.
Setting up condition based triggers incorrectly can lead to false alerts or missed failures. A structured approach is key to reliable results.
A trigger is only as good as the data it's based on. Using inaccurate or uncalibrated sensors will result in unreliable triggers and false alerts.
Setting too many triggers or thresholds that are too sensitive will overwhelm your team with alerts, causing them to ignore critical warnings.
Without a clear protocol for how to respond to a trigger, your team won't know what action to take. The trigger system must be paired with clear instructions.
A trigger system is most powerful when it's integrated with your CMMS, telematics, and other data sources. If systems don't "talk," you lose the ability to automate a full workflow.
Successfully rolling out a condition based trigger system requires a clear, phased approach involving data integration, rule setting, and continuous refinement.

Key questions for owners and executives about automating maintenance with triggers.
A simple telematics alert is a notification. A condition based trigger is a notification *plus* an automated action. It's the difference between a "check engine" light and a system that automatically creates a work order, assigns it to a technician, and orders the necessary parts when the light comes on.
Diagnostic fault codes (DTCs) are an excellent starting point. They are the most common and clear-cut signals of a problem. Once you've mastered DTCs, you can expand to more advanced data points like engine temperature, vibration, or fluid pressure. For complex predictive models, you can even use a trigger from a failure probability model.
Start small. Implement a few critical triggers and gradually expand as your team becomes comfortable. Use a tiered alert system (e.g., a "warning" email for minor issues and a "critical" text alert for imminent failure). Involve your team in setting the thresholds so they trust the system and understand its value.
The return on investment is significant. By preventing a single catastrophic failure, you can save tens of thousands of dollars in repair costs, tow fees, and lost revenue from unplanned downtime. It also allows you to optimize your service intervals, avoiding costly over-maintenance and extending the life of your most expensive components.
