Introduction

Configuration of condition monitoring units (CMU)

A condition monitoring unit (CMU) can acquire and analyze the signals from up to 32 vibration sensors in parallel. Signal acquisition for these vibration sensors is realized using IEPE modules. Up to 4 of these modules can be connected to the CMU and each module can measure up to 8 vibration sensors, resulting in the total of 32.

The measurement conditions, analyses, sensor assignment, measurement configuration, and communication protocols for the CMUs can be conveniently configured using ibaCMC.

The calculation results, data files and the CMU logs are imported cyclically by ibaCMC and are then available for further analysis.

This enables the configuration and subsequent analysis to be designed using one tool.

Data storage and trending

The results of the calculations are permanently saved in a database. Long-term storage enables trends to be identified using the trend analysis window. The raw data is saved on a file server as DAT files and is available directly in the web client for subsequent detailed analyses.

Time signal and spectrum analysis

In the trend analysis window, specific times can be analyzed in greater detail using high resolution time signals, FFT spectra, and envelope curve spectra. Damage patterns or anomalies in the signals can be identified in a separate analysis window using harmonics and sideband markers. The kinematic data for the components used is displayed in a table, enabling any damage to be identified in detail (e.g. to differentiate between inner and outer race damage on a bearing).

Dashboard

A dashboard provides you with a clear view of relevant characteristic values using tiles. A user can create a dashboard for their own use only or share it with other users by linking it to a plant tree item. Shared dashboards are indicated in the plant tree by a dashboard icon to the left of the plant tree icon.

Status reports

The system provides the user with a configured report log in the form of a PDF report that can be downloaded and sent by e-mail. The report provides an overview of status violations, sensor defects, and the measurement rate of the CMUs. The observation period and the transmission cycle can be configured.

E-mail notifications

It is possible to set alarms for specific items that result in e-mail notification. There are 3 different alarm levels with the following default values:

• Warning 70% of limit,

• Alarm 100% of limit

• Acute alarm 150% of limit

The repeat rate of the notifications can be set. The content of the e-mail is specified using editable templates.

Log book

The log book acts as the central tool for comments and documentation for analysts and plant operators. Different log types and status settings allow categorization of entries to provided a better overview. The log chart below the trend analysis chart shows the chronological sequence of the log entries on a timeline. This enables relationships between documented changes to a plant (e.g. bearing change, bearing lubrication, etc.) and significant jumps in trends to be identified.

Alarm list

The alarm list is a special view for showing all open alarms regarding specific plan tree components. In the alarm list you may acknowledge alarms and add comments.
