CMMS/EAM Functional Implementation Startup/Re-Start by Christopher N. Winston
CMMS-2005 Learning Zone Session
Computerized Maintenance Management Summit
July 26-29, 2005
Indianapolis Indiana
For many years now, CMMS/EAM implementations have often been at facilities that already have a computerized system in place. That system may have fallen into a limited use mode as resources are further and further constrained based on economic climate and other factors. We will also cover how re-implementations can occur without changing the system you have in place. The focus here will be on what to evaluate first, and additional tools to assist in the effort.
Join Christopher plus more than 35 other presenters, workshop leaders and learning labs directors at CMMS-2005.

Belt Tip
For future reference, write the sizes & types of belts used in your equipment at a safe but noticeable area of the belt cover/guard of the machine.
Use a Reflectorized Arrow Sticker (yellow) for rotation direction specially on pulleys without direction indicators.

Motor Testing Tip
Voltage and current readings can be used to provide some value as to the condition of your electric motor.
Voltage readings should be measured from phase to phase, such that you measure phase A to B, then phase A to C, then phase B to C. The primary reason is that different types of transformers will provide different phase to ground values that are not as effective in determining supply condition. The values will provide over/under voltage condition as well as voltage unbalance condition. The present limits are that the over/under voltage condition must not be more than 10% from the nameplate voltage, with the recommendation, for energy and reliability purposes, not to exceed 5% from nameplate. Voltage unbalance is the % unbalance from the average to largest difference from average voltage. This value should be less than 5% with a recommended limit being 2% and a de-rating factor provided for unbalances greater than 2%. For instance, a voltage unbalance of 5% requires a derating of the motor of 25% (ie: a 10 hp motor would be rated as 7.5%) to compensate for additional heating.
Current readings provide an indication of percentage of load, when measured above 50% of nameplate current. Current unbalance is a normal course of operation in motor circuits (exception: power factor correction will cause balanced current) that results from phase circuit: Impedance; Power factor; Loading; Voltage unbalance; and, Possible motor faults. Loading using current and voltage can be estimated:
Load = (I/Ir) x (V/Vr) x 100%
Where I is the RMS average current,
Ir is nameplate current,
V is RMS average voltage and
Vr is nameplate voltage.
RMS current readings, by themselves, can only provide an indicator as to potential condition, but should not be counted as a pass/fail indicator by itself, due to the number of conditions that contribute to current unbalance. For instance, a small motor drawing 10.1, 7.1 and 9.9 amps would have an unbalance of 22%, whereas a motor with a current draw of 100, 87, 97 amps would have an unbalance of 8%. In this example, the first motor was a 10 horsepower motor in good condition and the second motor was a 150 horsepower motor with a developing problem.
Understanding the abilities and limitations of the tools that you have available will assist you in making the right call to correct an existing or impending problem. When using voltage and current tests only, you have some limited capabilities. Utilization of other tools, such as power analysis, electrical signature analysis or motor circuit analysis techniques can be used to verify the actual condition of the system.

5th EPRI Conference on Maintenance
Hosted by PSE&G
August 8 - 10, 2005
Jersey City, NJ, USA
The electricity generation industry is continuing the rapid changes of the last five or more years from a stable, predictable past, to a future of competition, changing ownership, and dynamic new business goals. Adding to this new challenge, we are faced with the loss of long-term employees along with their knowledge. Many companies have mortgaged their human assets hoping to succeed in bridging the gap in knowledge and training without having developed a contingency plan.
The Electric Power Research Institute (EPRI) has structured this conference to provide some of the latest work being accomplished in the area of business evolutionary ideas, technology updates to forge ahead with more effective and efficient methods of completing maintenance work, as well as the ability to more accurately project what work has to be accomplished and when. This conference is structured for both the tactical maintenance needs as well as strategic ideas for focusing the future changes to be more successful.

Maintenance Metrics Tip
LEADING AND LAGGING INDICATORS
It seems that Leading and Lagging indicators are a mystery to many organizations. Organization that are operating without leading and lagging indicators operate similar to driving a car with the windshield painted black (you really cannot see where you are going).
Dr. Deming stated that “you cannot improve something you cannot measure”.
Most people agree with Dr. Deming but do not know how to develop leading indicators (which directly impact lagging indicators). I have heard many times, “I wish I could have seen this problem coming” or “I wish I could identify the root cause of my problems”. I am telling you here is the solution to most of your problems. A great example of a lead indicator is PM compliance (like everything else PM compliance is all in the definition). PM compliance is the measurement of the percentage of PMs that are completed in a specified period of time (watch future issue for my iPresentation about the 10% rule of Preventive Maintenance which defines PM compliance in a more rigid fashion). If your PM compliance is low it will directly impact your emergency labor hours which we would call a lagging indicator. Another example would be maintenance scheduled compliance (leading indicator) directly impacts production capacity (lagging indicator). The reason I used these examples is because I have seen these indicators provide great results in many plants I have visited so I know they work. I believe leading and lagging indicators must be developed from the maintenance crew level to plant management level. Clear away the black paint from your windshield and set up leading and lagging indicators for your operation.
When I was in maintenance management, “I wish I knew then what I know now”. “Knowledge is Power”.

Airborne Ultrasonic Tip
Acoustic Bearing Analysis:
When listening to bearings for analysis it is not recommended to solely go on “sound alone”. Decibels or the incremental changes/differences in the bearing over a period-of-time, is best. One bearing reading 58 db and low on grease can sound very much like a bearing with adequate wear that may warrant a removal/replacement.

Generating Failure Codes for CMMS Implementation by Bill Keeter
CMMS-2005 Learning Zone Session
Computerized Maintenance Management Summit
July 26-29, 2005
Indianapolis Indiana
One of the most important parts of CMMS implementation is the generation of failure codes for the craftsmen to record. Picking good codes means that you will have information that is useful for continuous improvement activities. Picking inadequate codes means that crafts people will soon grow tired of carefully entering codes that are not perceived to generate value for the organization.
In this session Bill will show you how to use Failure Modes and Effects Analysis to generate useful codes that will provide a path forward for continuous improvement. You will see how good codes can help you generate useful failure statistics so that you can forecast future failures and develop preventive/predictive activities that will minimize the business impact of failures.

Belt Tip
Belt Tip dated 04/07/05 was state below:
When removing belts from multiple belt pulleys, mark with chalk or crayon the order and the direction to the motor or drive they are coming off. 1,2,3,4,5,6 with an in or out arrow.
After all, that is why you bought a matched set. Putting them back on helter skelter any where will lead to vibration and possible bearing failure down the road.
My suggestion:
Since belts are no longer sold in matched sets, when replacing belts in multiple groove pulleys they should be vulcanized together under one backing, such as the Gates Powerband belts.
When removing Powerband belts mark the direction of rotation to the motor or drive they are coming off of with chalk or crayon and install it in the same orientation.
