2 General InformationThe 3500/25 Keyphasor Module is a half-height, 2-channel module used toprovide Keyphasor signals to the monitor modules in a 3500 rack. The modulereceives input signals from proximity probes or magnetic pickups and converts
the signals to digital Keyphasor signals that indicate when the Keyphasor markon the shaft is under the Keyphasor Probe. The 3500 Monitoring System canaccept four Keyphasor signals. A Keyphasor signal is a digital timing signal thatis used by monitor modules and external diagnostic equipment to measurevector parameters like 1X amplitude and phase.

When used in a TMR application, Keyphasor transducers may be connected tothe 3500 rack in two ways:
Redundant Keyphasor TransducersTwo independent Keyphasor transducers at each measurement location. This
configuration provides for both primary and secondary inputs and is the mostfault tolerant and reliable configuration. In this configuration, the primary andsecondary inputs will be connected to independent Keyphasor modules.
Single Keyphasor TransducersThis configuration requires only a single Keyphasor transducer. The signal fromthis transducer is wired to provide input to both Keyphasor Modules.
When used in a TMR application, only two speed measurement locations can besupported.
2.2 Available DataThe Keyphasor Module returns the rpm measured from each Keyphasortransducer. The rpm is the primary value and is used by the CommunicationGateway Module and the Rack Interface Module. The Keyphasor Module alsoreturns both module and channel statuses.
2.2.1 StatusesThis section describes the available statuses and where they can be found.
Module StatusOKThis indicates if the Keyphasor Module is functioning correctly. A not OKstatus is returned under any of the following conditions:

5 Maintenance
The boards and components inside of 3500 modules cannot be repaired in thefield. Maintaining a 3500 rack consists of testing module channels to verify that
they are operating correctly. Modules that are not operating correctly should bereplaced with a spare.
When performed properly, this module may be installed into or removed from therack while power is applied to the rack. Refer to the Rack Installation andMaintenance Manual (part number 129766-01) for the proper procedure.
This section shows how to verify the operation of a 3500/25 Keyphasor Module.
5.1 Verifying a 3500 Rack - Keyphasor
ModuleThe 3500 Monitoring System is a high precision instrument that requires nocalibration. The functions of Keyphasor Module channels, however, must beverified at regular intervals. At each maintenance interval, we recommend thatyou use the procedures in this section to verify the operation of all active channelsin the Keyphasor Module.

5.1.4 Using the Rack Configuration Software 24
5.1.5 Verifying Keyphasor Channels 26
5.1.1 Choosing a Maintenance IntervalUse the following approach to choose a maintenance interval:
Start with an interval of one year and then shorten the interval if any of thefollowing conditions apply:
- the monitored machine is classified as critical.- the 3500 rack is operating in a harsh environment such as in extreme
temperature, high humidity, or in a corrosive atmosphere.
At each interval, use the results of the previous verifications and ISOProcedure 10012-1 1992(E) to adjust the interval.

5.1.5.1 Test Equipment and Software Setup
The following test equipment and software setup can be used to verify Keyphasorchannels.
Test Equipment SetupSimulate the Keyphasor transducer signal by connecting the sync out of thefunction generator and the power supply to the Keyphasor I/O Module as shownin the figure on page 26 (Keyphasor Test Setup). Set the function generator toan initial frequency of 100 Hz and the power Supply to -7.00 Vdc.
Verification Screen SetupRun the Rack Configuration Software on the test computer. Choose Verificationfrom the Utilities menu and choose the proper Slot number and Channel numberthen click on the Verifybutton.
5.1.5.2 Verify Keyphasor ThresholdThe Keyphasor Threshold value is the voltage level where the Keyphasor signalwill turn on. This value can be set automatically or manually. Use the followingprocedure to verify that the Keyphasor Threshold is working correctly.
1. Disconnect PWR, COM, and KPH wiring from the channel 1 terminals on theKeyphasor I/O Module.
2. Connect test equipment and run software as described in Section 5.1.5.1(Test Equipment and Software Setup).
3. Observe the Keyphasor Verification screen:
If the channel is configured for Auto Threshold:
Verify that the Channel OK State Line reads OK
Verify that the Keyphasor RPM box display has an RPM value

If the channel is configured for Manual Threshold:
Adjust the Power Supply voltage to 2.50 Vdc more than the Thresholdvalue voltage level. For example
Displayed manual Threshold value = -10.00 Vdc+ -2.5 Vdc
---------------------Adjust the Power Supply voltage to: -12.50 Vdc
Verify that the Channel OK State Line reads OK
Verify that the Keyphasor RPM box display has an RPM value
4. If the Keyphasor channel will not produce a RPM reading, double check theinput signal to ensure it is correct. If the module still does not meet specificationsor fails any other part of this test, go to Section 5.1.6 (If a Channel Fails aVerification Test).
5.1.5.3 Verify Keyphasor RPM Values
The general approach for testing this parameter is to simulate the Keyphasorsignal with a function generator and power supply and verify that the correct RPMis produced. The RPM values are verified by varying the frequency of thefunction generator and observing that the correct results are reported in theVerification screen on the test computer.
NoteBefore this procedure can be used, check that the Threshold is set correctlyand the channel is OK.
1. Disconnect PWR, COM, and KPH wiring from the channel terminals on theKeyphasor I/O Module.
2. Connect test equipment and run software as described in Section 5.1.5.1(Test Equipment and Software Setup).
3. Adjust the function generator frequency to 100 Hz. Observe the KeyphasorVerification screen to find the number of Events Per Revolution. Use thefollowing equation to determine what the displayed RPM value should be:
Displayed Keyphasor RPM = (Frequency x 60) / Events Per Revolution
Example:
Frequency = 100 HzEvents Per Revolution = 10
Displayed Keyphasor RPM = (100 x 60) / Events Per Revolution= 6000 / 10= 600

4. Verify that the displayed Keyphasor RPM is within the specified tolerance.
Input Frequency (Hz) RPM Error
0.0167 to 100 1 RPM
101 to 500 8 RPM
501 to 20,000 1% of the RPM value
5. If the reading does not meet specifications, check that the input signal iscorrect. If the Keyphasor Module still does not meet specifications or fails anyother part of this test, go to Section 5.1.6 (If a Channel Fails a VerificationTest).
5.1.5.4 Verify Keyphasor OK
The general approach for testing this parameter is to cause a not OK conditionand observe that the correct results are reported in the Verification screen on thetest computer.
1. Disconnect the wire from the test equipment to the KPH input of theKeyphasor I/O module. The OK LED on the Keyphasor Module should go off.
2. Observe the Keyphasor Verification screen:
Verify that the Channel OK State Line reads not OK
Verify that the Keyphasor RPM box display reads Invalid
3. If the above results do not occur, double check that there is no input signal to
the Keyphasor Module. If the monitor still does not meet specifications or failsany other part of this test, go to Section 5.1.6 (If a Channel Fails a VerificationTest).
4. Disconnect the test equipment and reconnect the PWR, COM, and KPHwiring to the channel 1 terminals on the Keyphasor I/O Module.
5. Repeat all these procedures for channel 2 of the Keyphasor Module.
5.1.6 If a Channel Fails a Verification TestWhen handling or replacing circuit boards always be sure to adequately protect
against damage from Electrostatic Discharge (ESD). Always wear a proper wriststrap and work on a grounded conductive work surface.
1. Save the configuration for the module using the Rack Configuration Software.
2. Replace the module with a spare. Refer to the installation section in the 3500Monitoring System Rack Installation and Maintenance Manual (part number129766-01).
3. Return the faulty module to Bently Nevada Corporation for repair.
