In this group should be included the rest of the plant equipment which has an impact on the production and/or maintenance costs.
It is necessary to make an evaluation in order to determine, according to the equipment, the convenience of including it in the monitoring list. In some cases, the replacement costs are smaller than the annual costs required for the monitoring of the equipment in this priority section.
There is equipment that operates under the status of preventive maintenance, and there might also be equipment that operates till it brakes down. This does not imply that no sufficient attention has been dedicated to it.
Typical examples of this equipment are cooling ventilators of some frequency converters or direct current converters. In case some of these little ventilators suddenly stop, the panel's temperature monitoring system will send a warning on time and a stoppage could be prevented with another cooling method.
This is only an example; the best selection criteria will depend on the plant's working profile.
4.7 Conclusions
To achieve a successful implementation of the Preventive Maintenance System, the efforts need to be focused on the equipment catalogued as Very critical or
Critical (Priorities 1 and 2) during the first six months of the system's operation. This way, the maximum investment return efficiency will be realized.
As the program matures, the equipment that was classified as Priority 3 and 4 will be annexed.
The Predictive Maintenance Group will have to scrupulously review the initial list that includes all the plant equipment, and it should courteously involve the members of the production and maintenance in this process. The more information one has about the maintenance and repair time, the easier the classification task will be.

CHAPTER 5
Technical information by equipment type.
5.1 Introduction
One of the most important aspects in the Preventive-Predictive Maintenance System is the available information about the equipment parts. The more complete information about equipment components the easier will be the configuration process of the spectral alarm bands, as it will be seen in Chapter 6. In addition, the spectral analysis will be improved considerably with complete data information.
In this chapter, necessary forms will be presented to store the minimum required information of various equipment components. Due to the great diversity of equipment types, the major kinds of the most typical equipment in industry will be presented.
However, the user can elaborate a similar format for the types of equipment that are not included in this chapter.
5.2 Comments about the formats
The formats that are included in this chapter have in the right upper corner general information about the equipment.
The first three spaces were designed with appropriate lengths to include the appropriate information into the CSI Master Trend software. We are going to comment on different segments of this format.
EQUIPMENT IDENTIFICATION
The name of the equipment should be registered in alphabetical order with the maximum of 10 characters. CSI Master Trend will locate the equipment thanks to the assigned identification. The same identification will appear in the data collector, as well as in all the system's wave spectra and shapes reports. Consequently, it is very important to identify them according to plant's usage.
SECTION
In this space of 28 characters, one should include the name of the section to which the equipment belongs. For example:
Equipment: North Induced Draft Ventilator Identification: 5205-84
Section: Cement Kiln 2 TYPE OF EQUIPMENT
The specific work type performed by the equipment should be selected. This information will determine the way the information is registered. For example, when the velocity is constant and the load varies, it is recommended to record the load at the time of reading.
The Master Trend software requires this information when the equipment is included into the system.
MONITORING FREQUENCY
The schedule for the equipment's vibration reading needs to be determined. This decision depends on the equipment's priority in the process. The usual time sequence for the industrial equipment reading is one month (monthly).
The rest of the spaces is reserved for the specific data of each equipment part.
SCHEMATIC DIAGRAM
In addition, a schematic diagram of the equipment is included to show the place where the measurements should be taken.
The equipment's nomenclature of the measuring points is shown in each diagram.
The letters H, V and A will show the position of the sensor; which are respectively Horizontal, Vertical and Axial.
In case of the induction motors, E1H and E2H points will be added to record the low and high frequency spectra respectively in order to be able to counteract possible electric problems. The configuration of these measurement points will be explained in Chapter 6, Table III, pages 6-18.
In case of the gear boxes, it will be necessary to define additional monitoring points to record the gearing frequency. In the schematic diagrams, these measurement points should be identified.
The configuration of these points is shown on Table III, page 6-17.
ANALYSIS PARAMETERS
On the back of each form, the definition of the analysis parameters of the spectral bandwidth is included, as well as the alarm level that each band will have.
In some cases, the analysis parameters will be similar when they are in the same equipment subdivision, and it will be only necessary to refer to the equipment that has its parameters established in order to use them in the information recording.
In order to fill in correctly this table, it will be necessary to use the information from tables II and III, which are included in chapter 6.
