Read This First1-1Model 2120 Versions

This manual describes both the single-channel Model 2120A and the dual-channel Model 2120A-2. Descriptions of dual-channel functions apply to the Model 2120A-2 only.

This manual also applies to the original Model 2120 series analyzers except for the Expert menus described in Chapter 6.

This manual is also supplied with the corrective-only analyzer models; however, these models only allow operation of the balancing and align-ment programs. They do not allow access to any of the Route, Off Route, or Analysis mode functions.

Special Text

The following conventions are used throughout this manual to call special attention to the associated text:

NoteThe Note paragraph indicates special comments or instruc-tions.

Caution!The Caution paragraph alerts you to actions that could have an effect on the equipment or the collected data.

1-2

RBMware/MasterTrend Software and Prerequisites

In order to use the Model 2120A with RBMware/MasterTrend software, the software must be compatible as shown in the following table:Read This First

RBMware/MasterTrend requires a substantial amount of planning and setup before routes can be downloaded into the Model 2120. For example, a predictive maintenance database must be set up to define all machines, measurement points, alarm limits, and route formation. All of this informa-tion should be completely defined before you begin data collection.

Precau

Precautions

Please follow these precautions carefully. Any product damage due to these conditions may void the warranty.1-3tions

Do not change the battery pack with the battery charger connected as damage may occur to the analyzer.

Use only CSI-supplied battery chargers that have been approved for use with the Model 2120A Machinery Analyzer. The use of any other charger will most likely damage the analyzer.

Do not use CSI battery chargers with anything other than their cor-responding CSI product.

Do not use the Model 93140 Battery Charger Power Supply with older CSI Model 2100-series analyzers.

Do not connect a signal larger than 21 volts into the input of the analyzer.

Caution!CSI does not warrant compatibility or fitness for application of this product with any device not specifically recommended in CSI litera-ture. In some applications, special adapters may be required for inter-connectivity with other products. This includes the unbuffered outputs of some older on-line monitoring systems, particularly if configured with shutdown protection. If connected improperly to CSI equipment, systems can experience transient voltage conditions resulting in false vibration readings or system shutdown.

1-4

Standard Equipment and Options

Unpack the Model 2120A Machinery Analyzer and compare the contents of the package with your shipping invoice. If you should find a discrepancy, Read This First

contact CSI Customer Support.

Assembling the Case and Strap

A leather case with a shoulder strap and a clear vinyl jacket are provided to protect the Model 2120. Insert the top of the analyzer into the bottom of the leather case, making sure that the front display and keypad are visible through the cutouts in the case. Snap the bottom of the case shut, then clip on the leather straps and adjust them for your comfort.

1

When the analyzer must be used in a wet or humid environment, the clear vinyl cover can be used to help protect the face plate.

Battery

Battery Use and Care

A rechargeable battery pack is used to power the Model 2120. Before using the analyzer, verify that the battery has enough charge to operate properly. 1-5 Use and Care

The battery needs to be recharged if the analyzer will not power up, or if the analyzer displays a low battery warning and turns itself off.

The Battery Capacity function will give an approximate indication (in per-cent) of the batterys condition. To access this function, press the Utility key and select Check Battery from the menu. Alternatively, the battery capacity can be checked using the F1 Battery Check function that is available while in the normal route mode.

2

This display presents approximate values and should only be used as a guide-line in determining the amount of remaining battery charge. When the per-cent value first reaches zero, a built-in safety margin allows approximately 10 minutes of additional use before the analyzer turns itself off in order to protect the memory.

NoteIf the analyzer should display the low battery warning screen and turn itself off, the analyzers memory will remain intact for approximately two weeks. Therefore, the collected data is retained in memory and can be accessed after the analyzers battery has been recharged.

1-6

Recharging the Battery Pack

The Model 93140 battery charger power supply is used to charge the ana-lyzers battery pack. To recharge the battery pack:Read This First

1Make sure that the Model 2120A analyzer is turned off.

2Plug the Model 93140 power supplys AC power cord into a standard AC outlet.

3

3Insert the power supplys output plug into the battery charger jack located on the top panel of the analyzer.

4

powersupply

to ACwall outlet

Battery

The battery charger will recharge a fully discharged battery pack in approx-imately two and one half hours. After the battery pack has been fully charged, the battery charger will automatically switch to a trickle charge mode to maintain full charge.1-7 Use and Care

Caution!Do not use the Model 93140 Battery Charger Power Supply with older CSI Model 2115 analyzers.

The Model 2120A, with a fully charged battery, will operate continuously for approximately 12 to 14 hours, depending on the use of screen/keypad backlighting. Operational time can be increased by turning the analyzer off when not in use, and limiting the use of backlighting.

NoteThe original Model 2120 will operate continuously for approx-imately eight to 10 hours.

NoteTo prevent loss of memory, install a charged battery within four hours after removing a discharged battery.

NoteThe Model 93140 power supply can operate from any AC outlet ranging from 100 VAC to 250 VAC, 50 to 60 Hz.

NoteIt is normal for the bottom of the analyzers case to become warm to the touch towards the end of the charging cycle.

1-8

Changing the Battery Pack

To change the Model 2120A analyzers battery pack:

1Make sure that the analyzer is Off, and that the battery charger power Read This First

supply is not connected to the analyzer.2On the bottom of the analyzer, remove the two screws on the bottom

panel as shown below. Then remove the panel.

1-10

Battery Maintenance

The Model 2120A analyzer includes a function that allows you to automat-ically discharge the battery pack and then fully charge it. Although not absolutely necessary, this discharge/charge cycle helps the battery pack Read This First

maintain a strong charge and should be performed after every 25 to 35 charge cycles (or about once every six weeks).

If the battery pack is at or near a fully charged state, this function may take up to 10 hours to completely discharge the battery and an additional three hours to return the battery to a full charge. At some point in the discharge/charge cycle, the battery pack will be totally discharged and incapable of powering the analyzer should the need arise where the analyzer must be used. To prevent such a situation, either:

make sure that you have at least 13 hours before the analyzer must be used, or

begin the discharge/charge cycle when the analyzers battery is nearly fully discharged; that is, after the analyzer has been used for 11 to 14 hours (this can reduce the cycle time to four or five hours).

Discharging the Battery PackTo initiate the discharge/charge cycle for the analyzers battery pack, first connect the Model 93140 power supply as described in Recharging the Battery Pack on page 1-6. Press the analyzers Utility key, select Special Functions, and then select Discharge Batt from the Special Functions menu.

A verification screen will then be displayed to make sure that you wish to continue, toggle any numerical key to change the answer to Yes, and then press the Enter key. The analyzer will then display a screen informing you that the process has begun and then automatically turn itself off.

NoteThe Model 93140 power supply must be connected to the ana-lyzer throughout the discharge/charge cycle.

The Model 623BF contains buffering elec-tronics on the Volts input that reduce the likelihood of transient voltage conditions that can occur when connecting equipment to unbuffered voltage output sensors.

NoteThe Accel input should be used to connect to devices that require power from the Model 2120A (i.e. accelerometers). It must not be used to connect to unbuffered shutdown systems.

Model 628BVWhen using the Model 2120A-2 for dual channel voltage acquisitions with unbuffered voltage type sensors, the Model 628BV should be used. A typ-ical application for the Model 628BV would be measuring orbits using proximity probes on a system that has shutdown protection on the probe signal. The Model 628BV contains buffering electronics on both inputs, which reduce the likelihood of transient voltage conditions that can occur when connecting equipment to unbuffered voltage output sensors.

Selecting Measurement Points

There are three methods that can be used to select a measurement point from those in the current route. The first method is to simply scroll sequen-tially through the measurement points using the up/down arrow keys. This

MLUsing the Model 2120

is the usual procedure when following the order of measurement points in the route.

The left/right arrows can be used to jump to the first measurement point of the previous or next machine, respectively.

The F2 Machine List function key (on the measurement point display screen) can be used to individually select a machine and associated mea-surement point. After the F2 key has been pressed, the Machine List screen displays all of the machines within the current route and the measurement or worst-case alarm status of each machine. Use the up/down and left/right arrow keys to highlight the desired machine, and press the Enter key.

38

NoteAn asterisk (*) appearing before a machine name on the Route List screen indicates that data have not been collected on one or more measurement points of that machine.

Storing Data

During route data collection, the analyzer will store data according to the instructions loaded with the route from the RBMware/MasterTrend data-Using the Model 2120

base. For example, the analyzer may be instructed to store spectral and/or waveform data only on high alarm.

However, you may manually instruct the analyzer to store additional data regardless of the database instructions. This is accomplished by first dis-playing the data plot, then pressing the Save Data function key. Select Store Spectra, Store Waveform, or Store Both, and then press the Enter key. (See Store Data on page 7-21 for more information.)

regardless of the database storage instructions. These data, in addition to the analysis parameter values, may be observed at this time using the ana-lyzers functions keys.

Pressing the F3 Vibration Parameters (on the measurement point display screen) key will display the Vibration Parameters screen that shows the measurement description, measured values, units type, and alarm status of each individual analysis parameter as well as the overall level.

41

The Page Up or Page Down key can be pressed to advance to the spectral plot display (if spectral data are available) or the Enter key can be pressed to return to the measurement point display.

NoteIf more than six analysis parameters have been defined by RBMware/MasterTrend for the current measurement point, pressing a Page key while the Vibration Parameters screen is being displayed will show the extended parameters on a second page of Vibration Parameters. Pressing a Page key once again will display the spectral plot (if available).

Plot Display Control Keys

CursorThe cursor can be moved across the plot using the left/right arrow keys.

*3-27ying Data

The cursor position, indicated at the top of the plot box, indicates frequency and amplitude for spectral plots, or time and amplitude for waveform plots.

The cursor frequency (or time) increment is equal to the frequency resolu-tion which is explained in detail in Acquire Spectrum on page 7-23.

Expand and DecreaseThese keys are used to expand or compress the frequency axis of a spectral plot (or the time axis of a waveform) by a factor of two.

If the cursor is located at the left or right side of the plot, expansion/com-pression will begin from the minimum or maximum displayed frequency, respectively.

The left/right arrow keys can be used to move an expanded spectrum through the display window. In the following example, a spectrum from 0 to 500 Hz has been expanded to 0 to 250 Hz. With the cursor located at the right side of the plot box, the right arrow key will cause the remaining 250 Hz to 500 Hz section of the spectrum to move through the display window.

Pressing the right arrow key moves the remaining section of the spectrum through the display window.
