Understanding Condition-Based Alerts

In contrast to frequency-based preventive maintenance, condition-based maintenance uses upper and lower limits, tolerances, and other conditions that might cause an equipment or system warning or alarm to provide a system response to these conditions based on user, vendor, or manufacturer criteria.

The JD Edwards EnterpriseOne Condition-Based Maintenance (CBM) programs provide both real-time and batch connections to respond to alerts from equipment monitoring devices. For example, a wholesale food distributor monitors refrigeration equipment within cold storage and freezer rooms. If the temperature rises above a maximum level, the system provides an alert that can generate an investigation message, create a work order to service the equipment, or update a preventive maintenance schedule.

Dynamic systems (electrical, hydraulic, mechanical, or thermal) possess normal signatures when operating correctly. A subtle signature change might mean the onset of a failure mode. The small differences between normal and abnormal signatures are often hidden by noise in the system. However, modern transducers and associated signal-analysis techniques can now discriminate between truly random variations and significant trends. With equipment sensors that provide operating information, increasingly available technology supports real-time, on-board monitoring of equipment.

JD Edwards EnterpriseOne CBM enables you to:

  • Identify changes in the condition of a machine that will indicate a potential failure.

  • Identify physical characteristics that collectively indicate the current condition of a machine.

  • Measure, analyze, and report data to recognize trends.

Normally, an alarm condition generates a maintenance action, such as the creation of a work order to inspect, repair, or replace the cause of the alarm. Other alarms might send a pager alert, email message, or other electronic alert to the proper technician, supervisor, or individual who needs instant notification of critical equipment status.

JD Edwards EnterpriseOne CBM is also useful for budgeting considerations, such as planning for costly engine maintenance only when certain conditions occur.

Note: JD Edwards EnterpriseOne CBM supports receiving alerts and responding to them, but does not support receiving readings and analyzing them to determine whether an alert condition exists.
