Section 1 - Receiving and Handling Instructions

1. Receiving and Handling Instructions

1.1 Receiving Inspection

Visually inspect the module for obvious shipping damage. If you detect shippingdamage, file a claim with the carrier and submit a copy to Bently Nevada, LLC.

1.2 Handling and Storage Considerations

Application Advisory

The rack will lose hostcommunications and rack

configuration capabilities whenyou remove this module.

Circuit boards contain devices that are susceptible to damage when exposed toelectrostatic charges. Damage caused by obvious mishandling of the board willvoid the warranty. To avoid damage, observe the following precautions in theorder given:

1. Do not discharge static electricity onto the circuit board. Avoid tools orprocedures that would subject the circuit board to static damage. Somepossible causes include ungrounded soldering irons, nonconductive

plastics, and similar materials.

2. Personnel must be grounded with a suitable grounding strap (such as3M™ Velostat™ No. 2060) before handling or maintaining a printed circuitboard.

3. Transport and store circuit boards in electrically conductive bags or foil.

4. Use extra caution during dry weather. Less than 30% relative humiditytends to multiply the accumulation of static charges on any surface.

Section 2 - General Information

2. General InformationThe Transient Data Interface (TDI) is the primary interface into the 3500 rack. Itsupports a Bently Nevada™ proprietary protocol that software uses to configure

the rack and retrieve machinery information. TDI has 2 primary functions:configuration of the protection system and data retrieval for Bently Nevadamachine management systems.

You must place the TDI in slot 1 of the rack (next to the power supplies). Althoughthe TDI does provide certain functions common to the entire rack, the TDI is notpart of the critical monitoring path. The TDI's operation (or non-operation) doesnot effect the proper, normal operation of the overall monitoring system.

2.2 Triple Modular Redundant (TMR) DescriptionFor TMR applications, the 3500 system requires a TMR version of the TDI. Inaddition to all the standard TDI functions, the TMR TDI also performs "monitorchannel comparison." The 3500 TMR configuration executes monitoring votingusing the setup specified in the monitor options. Using this method the TMR TDIcontinually compares a specified output of 3 redundant monitors. If the TMR TDIdetects that the information from any monitor is no longer equivalent (within aconfigured percent) to that of the other 2 monitors, it will flag the monitor asbeing in error and place an event in the System Event List.

2.3 StatusThe Transient Data Interface returns both module and channel status. Thissection describes the available statuses and where you can find them.

Section 3 - Data Collection

3. Data CollectionThe Transient Data Interface is an integral communication processor that collectsand stores information from the 3500 monitors and transmits this information to

a host computer. This section describes how the data collection functions.

3.1 Overview

Data collected from a machine has several forms. This data includes static data,dynamic data, status information and speed data. The TDI acquires all of theseforms of data as a result of various stages of operation for a machine: steadystate, transient (start-up & coast-down) and when alarms occur. The TDI collects,stores, and transmits the data sets from the 3500 monitors to the dataacquisition computer. The data acquisition computer, in turn, provides the datato the database and display stations.

The TDI uses structures called Collection groups to organize data collection. Youshould place channels (measurement points) that are related to each other in thesame collection group. You create groups and add channels to them until youassociate all of the channels of the monitoring system with their respectivecollection group. The TDI collects all of the channel’s data within the collectiongroup together and synchronizes them with each other. You use System 1configuration software to create Collection Groups.

The TDI attempts to move data to the host computer at the earliest opportunity,so it identifies data that it collects as part of an event as being related to theevent and then sends the data using its network connections. If TDI is unable to

send the data it will store the data and send it when it is able to do so.

3.2 Definitions

Channels

The connection of a transducer to the system.

Collection Group

A group of channels (transducers) that are collected together. This is usedfor collection of data for alarms and during transient events.

Collection Group Enabler

A speed region that the user configures and that the TDI uses to enter intotransient collection mode.

Collection Control Parameter

A parameter that defines when to collect transient data.

exist within the 3500 TDI system: protection values, management values, andsoftware variables. Monitors generate and use protection values, compare themagainst setpoints, and protect the machine by using the results to control relays.The TDI uses the dynamic waveform information, applies signal conditioning andgenerates additional static values. Lastly, the software system retrieves thedynamic waveform information and generates additional values after applying

software calculations and signal conditioning.3.4.1.1 Protection Values

All of the static values that you configure or enable using 3500 monitorconfiguration are available through the TDI. The TDI does not re-compute orreplace any values that the monitors measure. All of the 3500 monitors canprovide these static values regardless of the monitor type and whether themonitor design supports the TDI (“M” vs. “non-M” series). Although both monitortypes support static values, one difference between non-M series and M seriesmonitors is that the M series can update static value faster than theirnon-management ready counterparts.

3.4.1.2 Management Values

The 3500 TDI takes the dynamic waveform from the management ready (“M”series) monitors and processes it to provide additional static values. These valuesthat the TDI computes are nX static values that return amplitude and phaseinformation of the vibration that relate to an order (nX) of running speed. The TDIcan calculate up to 4 nX values, which are available through the System 1software.


The TDI will mark phase information fornX values derived from 360x or 720xsynchronous sample rates as invalid.

The nX values require a speed input to the 3500 rack. The nX options available arebased on the synchronous sampling rate used for waveform sampling. You canadjust nX values in 0.01x steps.

0.1x to 359x, steps of 0.01x 720x (See note) 2,666 rpm


3.4.1.3 Software Variables

Software variables augment the static variables that the monitor and TDI provide.The software computes these variables after retrieving a waveform from the TDIand performing a series of calculations on the data. The software may driveAlarm data capture based on the values of these variables, but cannot issue aprotection alarm (relay closure).

3.4.2 Dynamic Data

Dynamic data, also known as waveform data or dynamic waveform data, isavailable from any “M” series monitor but is not available for “non-M” seriesmonitors. The TDI can collect waveform data for up to 12 monitors (48 channels).The TDI collects waveform data that is synchronous to the rotation of themachine and asynchronous to machine rotation for each channel. Each of the 2waveforms consists of 2048 samples of 16-bit data. The TDI samples waveformsfor all channels on a shaft simultaneously, which allows you to generate Orbits,perform modal analysis, and better determine the location of a fault.

The number of dynamic channels configured determines the maximum machinespeed that can be supported by TDI. Table 3-2 lists the available speed ranges.

Table 3-2: Supported TDI Speed Ranges

Number of Channels Minimum Machine Speed Maximum Machine Speed

1 to 16 1 rpm 100,000 rpm

17 to 32 1 rpm 60,000 rpm

33 to 48 1 rpm 30,000 rpm

3.4.2.1 Synchronous Data

Synchronous data requires a once-per-turn input to the rack. The TDI samples

data relative to this once-per-turn reference signal and uses a supportingpredictive algorithm to sample systems in which speeds are changing. Youconfigure the TDI to collect a defined number of samples for each rotation of theshaft, generally trading off between spectral resolution and waveform detail. Thespeed of the machine limits the upper sampling rates available. Table 3-3 lists thesampling rates and the maximum machine speed supported by the samplingrate.

3.4.2.2 Asynchronous Sampling

In addition to synchronous data, the TDI uses a fixed-frequency sampling rate tosimultaneously collect asynchronous waveforms. The TDI will collect a2048-sample data set that you can display as a waveform or an 800 linespectrum. The data collected in this manner is anti-alias filtered. The TDIsynchronizes sampling of channel pairs within a monitor, except for the 64kHzsampling rate, and you can use full spectrum plots to view the data. The followingtable shows the sampling rate, corresponding spectral frequency span and thenumber of spectral lines.


The TDI limits the number of channels ina collection group to 24 for 51.2kHz and

64kHz sampling rates.

3.4.2.3 Integration

You can configure the TDI to return integrated waveform data. The TDI will returnall of the waveform and nX values as integrated data if you select integration inthe protection system configuration.

3.5 Status Inputs

Monitors in the rack constantly inform the TDI of their status, which the TDIreports back to the host computer. The TDI reports operational status at achannel level. This status includes the alarm status and transducer OK status aswell as the TDI entering and leaving operating modes. The TDI also reportsmonitor health as part of the ongoing voltage and performance checks within themonitor and reports exceptions as a monitor event message.

3.6 Speed Inputs

The TDI accepts from 1 to 4 speed signals that are the same as the signalsavailable for the rest of the 3500 System. The TDI uses speed inputs to sampledata while acquiring synchronous waveforms and computing nX values. The TDIalso uses speed inputs to collect transient data. The TDI can useonce-per-revolution Keyphasor signals, multiple event-per-revolution speedsignals, or reciprocating (recip) multi-event wheels.

3.6.1 Multiple Event Keyphasor Signals

TDI supports the use of multiple event-per-revolution speed inputs. You mustconfigure the Keyphasor module to output a once-per-revolution signal to the3500 modules. When you configure the TDI for multiple event signals the TDI willmark all phase-related data as invalid.

3.6.2 Recip Multi-Event Wheel

A special configuration selection supports the recip multi-event wheel. This speedreference combines multi-event input for improved sampling with aonce-per-revolution indication for phase reference.

8/18/2019 1580E1 3500 22M



3.7 Data Collection Modes

The TDI delivers data to the host software for different causes. In some instancesit delivers data upon request from the software, such as for current valuesrequests. In other instances the TDI determines that the host should collect databased on the existing monitoring situation, such as when a monitor goes into

alarm. The following sections list the different causes of data collection. In eachcase the data content consists of the types of data described above, but taken atvarying density and frequency, and sometimes includes historical content.

3.7.1 Current Values

Note

Waveform data collection and storage is

an optional software feature that youmust purchase and then activate in TDI.

The TDI returns static values and waveforms when the host computer requeststhem. The software uses this data to provide both real-time data displays and toestablish historical trend and reference data. The software collects the staticvalues at 1-second intervals across the machine train to build historical trendplots. The host computer collects and stores historical waveform data at auser-defined interval. The system uses this collection in static, steady state andtransient software operation.

3.7.2 Alarm Data

The TDI will store a set of data for all the measurement points in the collectiongroup that occurs before and after an alarm event that occurs within the 3500rack. To provide the data prior to the event, the TDI records a running timewindow of static and waveform data. When an alarm occurs the TDI associatesthis data with the event and transmits it to the host computer. The TDI will thencollect additional data after the alarm event, associate it with the alarm andtransmit this data to the host. Since the TDI collects all of the data from acollection group, all of the waveform and steady state data between channels istime-coherent.

1 of 2 methods imitates alarm data collection:

1. If any static value within a collection group goes into alarm the TDI willcollect alarm data for all points in the collection group. The TDI collectsdata for both Alert and Danger alarms.

2. System 1 software can initiate an alarm event. This can occur if

15

• a software alarm occurs for one of the points within the collectiongroup, or

• a point in another rack that is associated by being in the samecollection group goes into alarm.

The TDI does not collect alarm data when the point leaves the alarm state, such

as when going from Danger to Alert, or from Alert to no alarm.

The data set for an alarm event on a dynamic point will typically consist of thefollowing:

• 20 seconds of 0.1-second interval static data just prior to the event(200 static data points);

• 1 data point from the time the event was detected;

• 10 minutes of 1-second interval static data from before the event (580static data points);

• 2.5 minutes of 10-second interval waveforms from before the event (15wave- forms);

• 10 seconds of 0.1-second interval static data from after the event (100static data points);

• 1 minute of 1-second interval static data from after the event (50 staticdata points);

• 1 minute of 10-second interval waveforms from after the event (6waveforms).

Data that the TDI collects for a static-only point, such as temperature, will be thesame except

• no waveform data is available, and

• the TDI limits the time resolution to once per second.

3.7.3 Issues With Alarm Collection

The time between the event and the first set of historical data can vary based onwhen the TDI sampled the data and when the alarm occurred. Therefore theinterval from the alarm event to the first of the pre-waveforms can vary from 0 to10 seconds. The older waveforms will be 10 seconds apart.

Because of machine speed or sampling rate the TDI may take longer than 10seconds to acquire a waveform. In this case the next waveform will begin at theend of the previous one and with more than 10 seconds between them. Becauseof this the pre-event data can have fewer than 15 waveforms data and thepost-event data can have fewer than 6 waveforms.

Once the TDI sends the data to the host it will not send the same data again.Therefore, if a collection group has multiple closely-spaced alarms, the TDI will notsent a full set of data for each alarm. However, software will be able provide all ofthe data that represent the event.

The alarm list indicates when the rack detects alarms. The event list does not logany alarm events that the software sends to the rack. There is no event list for thecollection of the data.

3.7.4 Transient Data

NOTE

Transient data collection is an optionalsoftware feature that you must

purchase and then activate in TDI.

The TDI has a special mode of operation for collecting data during transientoperation of the machine. The TDI collects transient data based on changes in

machine speed and at a configurable time interval. The TDI is always collectingspeed-based and time-based data. The TDI temporarily saves data but does notsend it to the host until the TDI detects that the machine is entering a transientmode of operation. When this happens the TDI transmits the last 200 datacollection sets to the host and continues to send new data sets until the end oftransient conditions are met.

17

8/18/2019 1580E1 3500 22M



To configure the TDI to collect data during transient events you must completethe following in System 1 Configuration:

• Place all of the channels into a collection group.

• Place a Keyphasor into the same collection group.

•

Define the Collection Group Enablers. These determine how the TDIcan determine that a machine is in transient operation.

• Define the Collection Control Parameters. These determine when theTDI will collect data.

3.7.4.1 Collection Group Enablers

Collection group enablers are rules that you define based on the machine speedthat determines when the machine has entered a transient mode of operation.When the TDI detects that the speed of the machine is within the defined region,it enters into transient collection mode. There are 2 collection group enablers

available for each collection group, which define the upper and lower speed of aspeed range. Normally you set one enabler range between slow roll (or stop) andrunning speed to capture machine start-ups and shutdowns. The intent of thesecond enabler, which you should set above normal operational speed, is tocatch overspeed events. Figure 3-2 show sample rpm ranges for the 2 collectiongroup enablers.

8/18/2019 1580E1 3500 22M



Once in transient mode the TDI will stay in the mode until the Host software tells itto exit transient mode. The software sends this command at a configured timeinterval after the TDI exits the Collection Group Enabler range.

Another way for the TDI to enter transient mode is through direct userintervention. You can use the Host software to issue a command for TDI to entertransient mode. This action bypasses the collection group enablers so that the

TDI immediately enters transient mode. TDI will then stay in transient mode untilyou manually remove it from transient mode.

3.7.4.2 Collection Control Parameters

You use the collection control parameters (CCP) to define when the TDI willcapture data. There are 2 types of parameters:

1. delta RPM, and

2. delta time.

Both of these types of parameters function simultaneously. Each collection groupoffers the following selections:

1. increasing delta rpm,

2. decreasing delta rpm, and

3. time interval.

All 3 of these selections can be active simultaneously for a collection group. Youcan program the increasing and decreasing delta rpm individually.

The time interval CCP defines a fixed time period that will cause the TDI to take a

data set. The time interval CCP will initiate data collection at the configuredinterval regardless of the speed of the machine.

The RPM-based CCPs uses changes in machine speed (either increasing ordecreasing) to force data collection. Once the TDI collects a data set at a givenspeed, it uses the delta rpm values to calculate 2 target rpm values, one forincreasing and one for decreasing speeds. When the machine speed reaches orexceeds either target value the TDI collects data and calculates the next targetrpm values.

Since the TDI uses the current speed to determine target values, and because theTDI may collect data at slightly higher or lower rpm values, the TDI may take datamay be at slightly different intervals even though the delta speed may be set (forexample) to 50-rpm intervals. See Figure 3-3.

Figure 3-3: Sample Delta Time and Delta RPM Sampling

When the TDI detects that it has entered into a transient region it will immediatelycollect a waveform and static data set. The TDI will collect 1 complete set of staticdata for all points in the collection group each time a CCP detects a collectionevent. Every 10 events the TDI will collect a waveform data set for all of thedynamic points in the collection group. The events can consist of both RPM CCPsand time CCP collections. Therefore, if the TDI detected 6 RPM-based events(increasing or decreasing) and 4 time interval events since the last waveformcollection, it would collect a new waveform. See Figure 3-4.

3.7.4.3 Issues with Transient Collection

If the software tells TDI to exit while still in a transient region the TDI will terminate

transient collection. The TDI will re-enter transient mode only when the machinespeed exits the enabler region and then re-enters that region or enters anotherenabler region. Under start-up conditions or after you reconfigure the TDI thehistorical buffer may not be full at the time of the event and the TDI will returnonly a partial data set.

You must take care when you configure the Collection Control Parameters fortransient data collection. The TDI can collect a large amount of data in a shorttime, and unless the system can transfer this data to the software the TDI’smemory will eventual fill up. The following guideline should help you optimize theTDI configuration.

System 1 / TDI can transfer a waveform set at a rate of 1 set per second. If youconnect 2 TDIs to a single DAQ and both TDIs are in transient mode, then thecomputer takes 2 seconds to collect a waveform set.

In addition to its alarm data storage and pre-transient data storage TDI hasenough storage to hold 35 waveforms sets internally.

The following equation determines the optimum Delta RPM value to set:

Section 4 - Configuration Information

4. Configuration InformationConfiguring the 3500/22M consists of 2 steps:

1. configuring the TDI to function as the Rack Interface Module, and

2. configuring the data collection system.

This manual covers configuring the Rack Interface Module. The System 1 helpsystem covers configuring data collection.

This section describes how to use the 3500 Rack Configuration Software toconfigure the Transient Data Interface. It also describes configuration restrictionsthat are associated with this module. Refer to the 3500 Monitoring System RackConfiguration and Utilities Guide and the Rack Configuration Software for thedetails on how to operate the software.

4.1 Transient Data Interface Considerations

4.1.1 3500 Rack Configuration

The Rear Port I/O option and the Power Supply option that the Transient DataInterface option screen specifies must match the physical components of thesystem. If the TDI finds a configuration mismatch, the rack will not accept thedownloaded configuration.

You must use the RS-232 port on the front panel to initially set the Ethernetparameters.

A Keyphasor or Tachometer module must be in the rack for the TDI to collectsynchronous data. If you assign a channel a Keyphasor signal and the module isnot in the rack, the rack will disallow the configuration.

The TDI requires that you select the same backup Keyphasor channel for everychannel that uses a given primary Keyphasor channel. If the backup Keyphasorassignment is inconsistent, the rack will disallow the configuration.

System uses the rack file as part of the configuration process. The rack file mustagree with the configuration in the physical rack, otherwise it will not initiate datacollection.

4.1.2 System 1

If a collection group contains more than 24 channels then that group will not offer20 kHz and 30 kHz as asynchronous frequency spans. Smaller collection groupscan still use 20 kHz or 30 kHz.

23

8/18/2019 1580E1 3500 22M



Waveform collection for a collection group is either Transient or Steady-State. Youcannot mix the 2 types of collection within a collection group. You can assignstatic-only points to collection groups with either transient or steady-statecollection.

You must manual place all channels that do not have a Keyphasor associationwithin the 3500 Rack Configuration in a collection group within System 1

Configuration. The System 1 software will automatically assign points withKeyphasor association to a collection group.

You should take care in setting the collection control parameters. If you use adelta rpm of 0.1 for a machine that runs at 30,000 rpm, the system will collect anexcessive amount of data during a startup.

If you change the protection system configuration, then data collection for therack will stop until you update the System 1 configuration to match the changes.

If you add a new monitor, the management system will ignore it until youconfigure it in System 1.

If you use the 3500 Rack Configuration software to configure a monitor channelfor integration, then the rack will integrate all of the management data for thechannel.

TDI can support up to a maximum of 12 “M” series monitors (3500/40M, /42M,/44M, /46M, /64M, /72M and /77M).

To view full spectrum data from asynchronous sampling the two channels mustbe from a single monitor channel pair and the sampling rate must be 20 kHz orslower.

When configured with a Shaft Absolute channel type, the TDI will return thewaveforms from the displacement waveform on the first channel and the shaftabsolute waveform on the second channel.

4.2 Configuration Process Overview

The initial TDI configuration involves several steps. We recommend the followinglist of steps as the recommended method for installing a TDI.

1. Install the TDI in the 3500 Rack.

2. Use the front port to configure the TDI’s Ethernet options.

3. Finish configuring the 3500 Rack via the front port or Ethernet port.

4. Save the rack file after downloading.

5. Use System 1 Configuration to add a 3500 Rack to the DAQ.

6. Import the rack file.

24

7. Configure the sampling configuration.

8. Configure the collection configuration.

Note that the System 1 help screens cover configuring the sampling andcollection configurations.

4.3 Transient Data Interface ConfigurationThis section describes the options available on the Transient Data Interfaceconfiguration screen.

Figure 4-1: Transient Data Interface Configuration Screen

Configuration ID:This is a unique 6-character identifier, which you entered when youdownload a configuration to the 3500 rack.

4.3.1 Rear Port

I/O Option

The I/O field lets you identify the type of I/O Module that is attached to themodule (The option selected must agree with the I/O module installed).These choices are:

• 10 Base-T/100 Base-TX

• 100 Base-FX

4.3.2 Ethernet (Rear Port)

Ethernet using TCP/IP is the primary communication interface for TDI. You mustconfigure several parameters to use the Ethernet communication interface.

25

8/18/2019 1580E1 3500 22M



Network Device Name

Use this parameter to give the rack a name by which it will be known onthe Network. The name must be 20 characters or less and cannot containany spaces.

Rack IP Address

The IP Address is a number that identifies the device on the network at asoftware level. Enter this value as a string containing 4 numbers between0 and 255. The system uses an IP address to identify and connect to arack across an Ethernet WAN or LAN.


IP Addresses of 0.0.0.0 and255.255.255.255 are not valid.

When configuring a new TDI, see your network administrator to obtain avalid IP Address.

Rack Subnet Mask

This is a string that the system uses to mask against the IP Address. TheRack Subnet Mask takes the form 255.255.0.0, 255.255.255.0, etc.

Gateway Address

The Gateway Address is the IP Address of the Gateway server. The systemuses the Gateway server to access addresses outside the local network.

Networks in which the Host Computer and the TDI are on the same localarea network do not need a Gateway. Contact your network administratorto obtain the gateway address.

4.3.3 Front Port

The primary purpose of the front TDI port that is labeled CONFIGURATION PORT isto allow you to configure the 3500 rack with a personal computer. You may alsouse the Data Acquisition/DDE Server Software and the Operator Display Softwarewith this port to retrieve machinery data for display. This port supports RS-232only and provides access to only one rack.

External Modem

The Transient Data Interface directly supports the following externalmodems:

• None

• Hayes Ultra 9600

26

8/18/2019 1580E1 3500 22M



• Hayes Optima 9600

• Motorola FasTalkII 14400

• US Robotics 56k

• Custom

Initialization String

The Initialization String is the command that sets up and starts themodem. If you select a modem from the list, the software will display thedefault initialization string in this field. If you select Custom, enter aninitialization string from information in the modem's documentation.

Byte Timeout

The Byte Timeout is the number of byte times for which thecommunication line must be idle before the rack considers acommunication to be complete. One byte time is a function of the baudrate selected. The range of values is 3 to 255.

4.3.4 Passwords

Connect Password

The Connect Password provides read-only access to the 3500 rack. If thepassword entered in this field does not match the password entered in theRack Configuration Software "Connect" screen or in the Data Acquisition/DDE Server Software "Setup" screen, the 3500 rack will not allow you tocommunicate with it. The rack stores this password in non-volatile

memory in the Transient Data Interface.

Configuration Password

The Configuration Password provides configuration write access to the3500 rack. If the password in this field does not match the password youentered in the Rack Configuration Software "Download" screen, the 3500

rack will not accept new configurations. The 3500 rack requires you toalso enter this password to change setpoints in the 3500 rack from theOperator Display Software. The rack stores this password in non-volatilememory in the Transient Data Interface.

4.3.5 Rack Mounting Option

This option lets you select the type of 3500 rack that is installed or that you willinstall. Refer to the 3500 Monitoring System Rack Installation and MaintenanceManual for a description of the various mounting options.

4.6 Hardware Switches

The Transient Data Interface has 3 hardware switches on its front panel.

4.6.1 Key Switch

The key switch prevents unauthorized changes to the configuration settings.When the switch is in the RUN position, you cannot configure the 3500 rack.When the switch is in the PROGRAM position, you can configure the 3500 rackand the rack continues to operate normally. By removing the key, you can lockthe Transient Data Interface in the RUN or PROGRAM position.

4.6.2 Rack Reset


You must insert an I/O module for theRack Reset switch to function correctly.

When you press the Rack Reset switch is pressed, any monitors in the rack willclear latched alarms and reset Timed OK Channel Defeat indications. If the

Configuration LED is blinking at 5 Hz, it will stop blinking. This switch performs thesame function as the Rack Reset contact on the Rack Interface I/O Module.

4.6.3 Rack Address

You use the rack address to identify individual 3500 Racks on the network. You setthe rack address by using a 7-position DIP switch, which provides for 127 possibleaddresses. All racks on a local area network should have a unique rack address.The following diagram and table show how to select the address 0110001 (49decimal).

Section 5 - I/O Module Description

5. I/O Module DescriptionThe Transient Data Interface requires one I/O module and supports an optionalsecond I/O module. The TDI requires a Transient Data Interface I/O Module, which

connects the TDI to a network using Ethernet. The second module is the BufferedSignal Output Module, which provides the buffered signals from the vibrationmonitors.

This section describes how to use the connectors on the I/O modules, lists whatcables to use, and shows the pin outs of the cables.

You can install only 1 Transient Data Interface I/O Module at a time behind theTransient Data Interface (in a Rack Mount or a Panel Mount rack) or above theTransient Data Interface (in a Bulkhead rack).

Also, you may install 1 Buffered Signal Output Module between the Power Input

Modules and the Transient Data Interface I/O.

5.1 Transient Data Interface Input/Output (I/O) Modules

The 3500 Monitoring System has 2 types of Transient Data Interface I/O Modules:

1. the 10 Base-T/100 Base-TX Ethernet I/O (RJ-45), and

2. the 100 Base-FX Ethernet I/O (Fiber Optic).

You must install the Transient Data Interface I/O module behind the TransientData Interface (in a Rack Mount or Panel Mount rack) or above the Transient Data

Interface (in a Bulkhead rack).

• A module experiences Slot ID Failure (i.e., a module cannot determinewhich slot it occupies)

• Any module in the 3500 rack detects a fault

• Any module experiences Communication Failure

•

You configure any of the following security options and the rack meetstheir conditions:

- You change the rack address while the TDI is in Run mode.

- You insert any module into or remove any module from the rack.

- You change the key switch from Run mode to Program mode.

5.1.2 Communications Interface

The TDI Ethernet port connects the 3500 rack to the host computer’s 10- or 100-Megabaud Ethernet local area network. This connection can either use the RJ-4510 Base-T/100 Base-TX connector or the 100 Base-FX connector. The TDIsupports standard LAN architectures and can be routed to the host via hubs andswitches.

37

8/18/2019 1580E1 3500 22M



5.1.2.1 10 Base-T/100 Base-TX

The RJ-45 port connects the TDI to the host computer through an Ethernetnetwork. This connection requires UTP Category 5 network cabling with RJ-45connectors. This port supports a maximum cable length of 100 m (328 ft).

5.1.2.2 100 Base-FX

The MT-RJ fiber optic port connects the TDI to the host computer through anEthernet network. This connection requires MT-RJ Multi-mode fiber optic networkcabling. The TDI supports a maximum length of 400 m (1312 ft).

5.1.3 External Contacts

The TDI external contacts require dry contact inputs to operate. To enable aspecific function, short the desired contact to a system common (COM).

5.1.3.1 Trip Multiply (TM)

When activated, this contact places the entire rack in Trip Multiply.

5.1.3.2 Rack Alarm Inhibit (INHB):

This contact prevents the 3500 rack from declaring an alarm for any monitor orrelay in the rack. You typically use this feature when performing maintenancefunctions. When Rack Alarm Inhibit is active, it will take monitors in alarm out ofalarm and place the rack OK relay the Not OK state.

5.1.3.3 Rack Reset (RST)

This contact signals when the modules in the 3500 rack are to be reset. This

contact has the same function as the Rack Reset switch on the front panel of theTransient Data Interface.

5.1.4 Wiring I/O Style Connectors

To remove a terminal block from its base, loosen the screws attaching theterminal block to the base, grip the block firmly, and pull as shown in Figure 5-2. Do not pull the block out by its wires because this could loosen or damage thewires or connector.

5.2 Buffered Signal Output Module

The Buffered Signal Output Module is an optional module that, when used withthe Bently Nevada Diagnostic Access Panel (Catalog Number 3500/08), providesaccess to all of the buffered signals. Additionally, you can access the conditionedKeyphasor signal through this module. You must install the module behind the

Power Supplies between the Power Input Modules and the Transient DataInterface I/O Module (in a Rack Mount or a Panel Mount rack), or above the PowerSupplies between the Power Input Modules and the Transient Data Interface I/OModule (in a Bulkhead rack). The I/O module has 4 connectors, as shown in Figure5-6:

Section 6 - Maintenance

6. MaintenanceThis section shows how to verify that the Transient Data Interface and the I/Omodules are operating correctly.

When performed properly, you may install this module into or remove this modulefrom the rack while power is applied to the rack. Refer to the Rack Installation andMaintenance Manual (part number 129766-01) for the proper procedure.

6.1 Verification

Before running the TDI Host Port Test Utility, connect the host to the rack witheither a RS-232 cable to the front of the TDI. Then use the TDI Host Port TestUtility to verify that the HOST ports on the Transient Data Interface and the TDI I/OModule are operating properly.

Refer to the 3500 Monitoring System Rack Configuration and Utilities Guide andthe Rack Configuration Software for the details of this utility.

6.2 Performing Firmware Upgrades

Occasionally you may need to upgrade the original firmware that was shippedwith your 3500/22M TDI. The following instructions describe how to use the 3500Configuration Software to upgrade your existing firmware.

Application Alert

During the following procedure the rackmust not lose power and you must notremove the TDI from the rack. If eitherof these occurs the TDI may become

inoperable.

1. Close System 1 Data Acquisition.

2. Start the 3500 Configuration software and connect to the rack. Use theEthernet port to upgrade the firmware, due to the length of the files thatyou must download.

3. Upload and save the current configuration of the module. Although themodule retains the current configuration during the upgrade, saving thepresent configuration will help if any problems arise during the upgradeprocess.

4. Under the Utilities menu option select Update Firmware.

45

8/18/2019 1580E1 3500 22M



5. Select the module you wish to update (the Transient Data Interface) andclick on the OK button. See Figure 6-1.

Figure 6-1: Firmware Download Screen

6. The software will request you to select the file you wish to download.Select the file and click on the Open button.

7. The software will now download the file. If the process fails, the modulewill revert to its old code. Under no circumstances should you remove theTDI until the download process finishes.

8. After the download process is complete, the module will restart and thesoftware will disconnect from the rack.

9. Once the module has completed its startup, use the 3500 ConfigurationSoftware to reconnect to the rack.

10. The software will request you to download the DSP code files. Select eachof the 4 DSP code files and click on the Open button. The software willnow download the files.

11. Once the download process is complete, cycle power to the module. You

can do this by either by removing and reinstalling the module or byremoving power from and reapplying power to the rack.

This disk enables the number of channels of dynamic data (the ability to collect

waveforms) that the TDI will support. There are 2 levels of dynamic data:

1. steady-state points, and

2. transient points.

Steady-state points are channels that collect waveform data either due to asoftware command or due to an alarm event, and therefore support currentvalues, scheduled waveform capture. and alarm data capture.

Transient points provide all the functionality of a steady-state point and addwaveform collection due to parameter variations, such as machine speed.

3500/09-AXXX-BXXX

A: Steady-State Points

Specify from 0 to 672 steady-state points.

9.3 Controls

9.3.1 Front Panel

Rack reset button

Clears latched alarms and Timed OK Channel Defeatin the rack. Performs same function as the “RackReset” contact on I/O module.

Address switch

Used to set the rack address; 127 possible addresses.

Configuration Key Switch

Used to place the 3500 rack in either “RUN” mode or“PROGRAM” mode. RUN mode allows for normal

operation of the rack and locks out configurationchanges. PROGRAM mode allows for normaloperation of the rack and also allows for local orremote rack configuration. The key can be removedfrom the rack in either position, allowing switch toremain in either RUN or PROGRAM positions. Lockingswitch in the RUN position allows you to restrictunauthorized rack reconfiguration. Locking switch inPROGRAM position allows remote configuration ofthe rack at any time.

9.4.2 Alarm Data Collection

Alarm Data Collected

Pre- and post-alarm data.

Data Values Collected

1-second static values collected for 10 minutes

before the event and 1 minute after the event.100 ms static values collected for 20 seconds beforethe event and 10 seconds after the event.

2.5 minutes of waveform data at 10-second intervalsbefore the alarm and 1 minute collected at 10-second intervals after the alarm.

9.4.3 Static Values Data

Static Values Collected

TDI will collect the static values including the values

measured by the monitors.

nX Static Values Collected

TDI provides four nX static values for each point. TheTDI returns amplitude and phase for each of thevalues.

9.4.4 Waveform Sampling

Data Collection

Collection of waveforms for 48 channels.

DC-coupled waveforms.Data Sampling Operation

Simultaneous Synchronous and Asynchronous datasampled during all operational modes.

Synchronous SamplingRates

User-configurable Synchronous waveform samplingrates:

• 1024 samples/rev for 2 revolutions,

• 720 samples/rev for 2 revolutions,• 512 samples/rev for 4 revolutions,





• 32 samples/rev for 64 revolutions, and80

8/18/2019 1580E1 3500 22M



• 16 samples/rev for 128 revolutions.

Asynchronous Sampling

Asynchronous data sampled to support an 800-linespectrum at the following frequency spans:

• 10 Hz

• 20 Hz• 50 Hz

• 100 Hz

• 200 Hz

• 500 Hz

• 1000 Hz

• 2000 Hz

• 5000 Hz

• 10 kHz

• 20 kHz

• 30 kHz

Asynchronous data is anti-aliased filtered.

Channel Pair Support

You can split a Channel Pair among multiplemonitors to provide Orbit or synchronous fullspectrum presentations.

For asynchronous full spectrums the channels mustbe within a monitor channel pair (the TDI will not

phase correlate 30 kHz frequency span databetween channel pairs).
