Automated Maintenance Data Collection & Preventive Maintenance in Automated Systems Presented in Partial Fulfillment

1. Automated Maintenance Data Collection & Preventive Maintenance in Automated Systems Presented in Partial Fulfillment of Course Requirement for IEM5303 Michael D. Blanton Applications Engineer, Governair Corporation 2000 Mike Blanton

2. Focus of Paper • Automated Data Collection • Where Automated Data Collection is currently used in building systems. • How Automated Data Collection can Improve Preventive Maintenance. • How Automated Data Collection can Improve an Organizations Profitability. 2000 Mike Blanton

3. One Current Use (1) • In Building Automation Systems (BAS) • A BAS uses automated data collection to display data on computer monitors. • Automated data collection has been used in BAS systems sense the 1980’s. • In a BAS data is display on monitors to show status of building systems. • A BAS is primarily used to control heating, ventilating and air-conditioning systems • Can be integrated with other building systems such as fire systems, security and etc. 2000 Mike Blanton

4. One Current Use (2) • In Building Automation Systems (BAS) (cont.) • Data collected in a BAS is not used for preventive maintenance purposes. • A BAS notifies maintenance when a problem has already occurred not before. 2000 Mike Blanton

5. Potential Use (1) • Computerized Maintenance Management Systems (CMMS) • A CMMS is used to organize and improve the performance of manual maintenance programs (preventive maintenance) by: • Scheduling employees • Issuing and tracking work orders • Scheduling preventive maintenance tasks • Storing tasks required for preventive maintenance on each piece of equipment • Tracking Inventory • Etc. 2000 Mike Blanton

6. Potential Use (2) • Computerized Maintenance Management Systems (CMMS) (cont.) • Data collection in a CMMS is normally accomplished manually. • Time consuming, expensive and random. 2000 Mike Blanton

7. Improve Preventive Maintenance (1) • By Moving a CMMS from a Preventive to a Predictive System. • The transition is accomplished by building a history of normal operating points of equipment. • Data collection through the use of automated data collection devices can be accurate, timely and inexpensive. • Data is collected through the use of a variety of transducers and sensors. • The data helps detect anomalies in equipment operation. 2000 Mike Blanton

8. Improve Preventive Maintenance (2) • By Moving a CMMS from a Preventive to a Predictive System. • The transition is accomplished by building a history of normal operating points of equipment (cont.). • These anomalies are telltale signs of equipment breakdowns. • The anomalies allow advance investigation prior to actual equipment failure. • This reduces the impact of possible breakdown. 2000 Mike Blanton

9. Automated Data Collection Devices • Johnson Controls Devices • Electronic Temperature Sensor • CO2 Sensor • Occupancy Light Switches • Pneumatic and Electronic Actuators 2000 Mike Blanton

10. Automated Data Collection Devices (2a) • Production Process Corporation Components • MTD-01 offers • Lowest cost data collection • No data display. • Plug-in module mounts in machine cabinet • Size: 4"H x 2"W x 2.5"D • Automated data collection can cost as little as $250.00 per machine (plus software). 2000 Mike Blanton

11. Automated Data Collection Devices (2b) • Production Process Corporation Components • MDT-11 offers • Numeric data display of 15 data functions • Automatic input of 5 downtime reasons. • Slow machine alarms • Multiple totalizers • Size 3"H x 5.5"W x 3.5"D • Automated data collection can cost as little as $250.00 per machine (plus software). 2000 Mike Blanton

12. Improved Profitability • Through the use of Automated Data Collection an Organization can: • Reduce Maintenance Cost • By helping to predict equipment failures prior to catastrophic failures. • Reducing cost of having parts delivered overnight. • Reducing parts inventory • Increase Uptime of Equipment. • Predicting failures which allows scheduled downtime without disrupting production. • Reducing failures by improving overall maintenance on equipment. 2000 Mike Blanton

13. Reduced Maintenance Cost and Increased Uptime both translate directly to the bottom line of an organization. The bottom line is increased profitability. 2000 Mike Blanton
