The 3500/44 accepts input from two separate Keyphasor7signals allowing eachchannel pair to execute a different tracking filter.
The 3500/44 is designed to meet the recommended requirements of thefollowing Aeroderivative Gas Turbine Manufacturers:
Rolls Royce RB211
General Electric LM1600, LM2500, LM5000, LM6000Turbo Power and Marine
Allison 501
The primary purpose of the 3500/44 monitor is to provide 1) machineryprotection by continuously comparing current machine vibration againstconfigured alarm setpoints to drive alarms and 2) essential machine vibrationinformation to both operator and maintenance personnel. Alarm setpoints areconfigured using the 3500 Rack Configuration Software. Alarm setpoints canbe configured for each active proportional value and danger setpoints can beconfigured for two of the active proportional values.
When shipped from the factory, the 3500/44 is delivered unconfigured. Whenneeded, the 3500/44 can be installed into a 3500 rack and configured toperform the required monitoring function. This lets you stock a single monitorfor use as a spare for many different applications.
2.1 Triple Modular Redundant (TMR) DescriptionWhen used in a TMR configuration, 3500/44 monitors and Aeroderivative GTVibration TMR I/O Modules must be installed adjacent to each other in groups ofthree. When used in this configuration, two types of voting are employed toensure accurate operation and to avoid single point failures.
The first level of voting occurs on the TMR Relay Module. With this voting, theselected alarm outputs for the three monitors are compared in a 2 out of 3method. Two monitors must agree before the relay is driven. Refer to the3500/32 & 34 Relay Module Operation and Maintenance Manual for moreinformation on this voting.
The second type of voting is referred to as "Comparison" voting. With this typeof voting, the proportional value outputs of each monitor in the group arecompared with each other. If the output of one monitor differs from the outputof the other monitors in the group by a specified amount, that monitor will addan entry to the System Event list. Configure comparison voting by settingComparison and % Comparison in the Rack Configuration Software.
Comparison
The enabled proportional value of the TMR monitor group that is used todetermine how far apart the values of the three monitors can be to each otherbefore an entry is added to the System Event List.

% Comparison
The highest allowed percent difference between the middle value of the threemonitors in a TMR group and the individual values of each monitor.
For TMR applications, two types of input configurations are available: bussed ordiscrete. Bussed configuration uses the signal from a single nonredundant
transducer and provides that signal to all three monitors in the TMR groupthrough a single 3500 Bussed External Termination Block.
Discrete configuration requires three redundant transducers at eachmeasurement location on the machine. The input from each transducer isconnected to separate 3500 External Termination Blocks.
2.2 Available DataThe Aeroderivative GT Vibration Monitor returns specific proportional values.This monitor also returns both monitor and channel statuses.
2.2.1 Statuses
The following statuses are provided by the monitor. This section describes theavailable statuses and where they can be found.
Monitor Status
OK
This indicates if the monitor is functioning correctly. A not OK status isreturned under any of the following conditions:
Module Hardware Failure
Node Voltage Failure Configuration Failure
Transducer Failure
Slot ID Failure
Keyphasor Failure (if Keyphasor signals are assigned to channel pairs)
Channel not OK
If the Monitor OK status goes not OK, then the system OK Relay on theRack Interface I/O Module will be driven not OK.
Alert/Alarm 1
This indicates whether the monitor has entered Alert/Alarm 1. A monitor willenter the Alert/Alarm 1 state when any proportional value provided by themonitor exceeds its configured Alert/Alarm 1 setpoint.

Danger/Alarm 2
This indicates whether the monitor has entered Danger/Alarm 2. A monitorwill enter the Danger/Alarm 2 state when any proportional value provided bythe monitor exceeds its configured Danger/Alarm 2 setpoint.
Bypass
This indicates when the monitor has bypassed alarming for one or moreproportional values of a channel. When a channel bypass status is set, thismonitor bypass status will also be set.
Configuration Fault
This indicates if the monitor configuration is valid.
Special Alarm InhibitThis function inhibits all alarms for the associated channel. The MonitorSpecial Alarm Inhibit does not reset latched alarms. The latched alarms willbe driven after the inhibit function is deactivated. The inhibit functionprevents the OK status of the Keyphasor channel from voting into thechannel OK status. When this inhibit function is activated from the externalcontacts on the I/O module, all active channels of the associated monitorare affected.
The Monitor Special Alarm Inhibit function is active when:
The Alarm Inhibit contact (INHB/RET) on the I/O module is closed(active).
Any of the Channel Special Alarm Inhibit software switches is enabled.
Channel Status
OK
This indicates that no fault has been detected by the associated monitorchannel.
There are three types of channel OK checking: Transducer Input Voltage,Transducer Supply Voltage, and Keyphasor OK. Keyphasor OK only affects
channel pairs that have Keyphasor signals assigned to them. A channel OKstatus will be deactivated if any of the three OK types goes not OK.
Alert/Alarm 1
This indicates whether the associated monitor channel has enteredAlert/Alarm 1. A channel will enter the Alert/Alarm 1 state when anyproportional value provided by the channel exceeds its configured
Alert/Alarm 1 setpoint.

Danger/Alarm 2
This indicates whether the associated monitor channel has enteredDanger/Alarm 2. A channel will enter the Danger/Alarm 2 state when anyproportional value provided by the channel exceeds its configured
Danger/Alarm 2 setpoint.
Bypass
This indicates that the channel has bypassed alarming for one or more of itsproportional values. A channel bypass status may result from the followingconditions:
A transducer is not OK, and the channel is configured for Timed OKChannel Defeat.
The Keyphasor associated with the channel has gone invalid causing all
proportional values related to the Keyphasor signal (for example 1XAmplitude, 1X Phase, Not 1X, ...) to be defeated and their associatedalarms bypassed.
The monitor has detected a serious internal fault.
A software switch is bypassing any channel alarming function.
The Special Alarm Inhibit is active and causing enabled alarms not to beprocessed.
Special Alarm Inhibit
This function inhibits all alarms for the associated channel. The ChannelSpecial Alarm Inhibit does not reset latched alarms. The latched alarms willbe driven after the inhibit function is deactivated. The inhibit functionprevents the OK status of the Keyphasor channel from voting into thechannel OK status. When this inhibit is activated from the external contactson the I/O module, all active channels of the associated monitor areaffected.
The Channel Special Alarm Inhibit function is active when:
The Alarm Inhibit contact (INHB/RET) on the I/O Module is closed(active).
A Channel Special Alarm Inhibit software switch is enabled.
Off
This indicates whether the channel has been turned off. The monitorchannels may be turned off (inactivated) using the Rack ConfigurationSoftware.

3.2 Channel OptionsThis section discusses the Configuration Considerations and the RackConfiguration Software screens associated with the Aeroderivative Channel.
3.2.1 Aeroderivative Channel Configuration Considerations
Consider the following items before configuring an Aeroderivative Channel:
If a Keyphasor channel is selected, a Keyphasor Module must be installed inthe rack.
The full-scale options allowed for each proportional value is dependent uponthe transducer type.
Setpoints may only be set on proportional values which are enabled.
When a full-scale range is modified, readjust the setpoints associated withthis proportional value.
If either 1X Amplitude (Ampl) or Band-pass is enabled and the Integrate boxis checked, the Trip Multiply value must be set to 2.0 or less.
Only one or two proportional values (Direct, 1X Amplitude (Ampl), or Band-pass) can be enabled at the same time.
NoteFor TMR applications, set Channel Pair 1 and 2 as primary Keyphasor andChannel Pair 3 and 4 as backup Keyphasor.

Trip Multiply
The value selected to temporarily increase the alarm (Alert and Danger) setpointvalues. This value is normally applied by manual (operator) action duringstartup to allow a machine to pass through high vibration speed ranges without
monitor alarm indications. Such high vibration speed ranges may includesystem resonances and other normal transient vibrations.
Transducer Selection
The following transducer types are available for the Aeroderivative Channel:
86497 Interface Module
86517 Interface Module
Nonstandard
1X tracking Filter
The normal operating speed specifies the typical operating speed of themachine and the bandwidth filter specifies the width of the 1X tracking filter.
Acceptable values are 3 Hz and 5 Hz. These options determine the filter Q forthe 1X Amplitude proportional value. The 1X channels provide the amplitude ofthe casing vibration at shaft rotative speed but without a phase angle. Thechannels provide this amplitude by using narrow bandpass filters thatautomatically adjust the center of frequency of the filters to match shaft rotativespeed. The filters are constant Q filters which means that they change thebandwidth in proportion to the center frequency of the filter. The bandwidth of
the filter, therefore, changes in proportion to rotor speed. For example, as therotor speed increases the bandwidth will get larger, and as speed decreases thebandwidth will get smaller.
The Q value of the filter is determined by the center frequency of the filter(which is equal to the normal operating speed divided by 60) and the desiredbandwidth as shown in this relationship:
Q is proportional to: (center frequency) / (bandwidth)

Latching
Once an alarm is active it will remain active even after the proportional valuedrops below the configured setpoint level. The channel will remain in alarmuntil it is reset by using one of the following methods:
the switch on the front of the Rack Interface Module
the contact on the Rack Interface I/O Module
the Reset button in the Operator Display Software
the reset command through the Communication Gateway Module
the reset command through the Rack Configuration Software
Nonlatching
When an alarm is active, it will go inactive as soon as the proportional valuedrops below the configured setpoint level.
Alert should be the first level alarm that occurs when the transducer signallevel exceeds the selected value. Danger should be the second level alarmthat occurs when the transducer signal level exceeds the selected value.The Alert and Danger values are set on the Setpoint screen.
Barriers
Select the external option if there are external barriers connected between the
monitor and the transducer. Barriers are used to restrict the amount of energythat can flow into a hazardous area.

The 100 ms option applies to the Danger time delay only and has thefollowing results:
If the 100 ms option is off ():
The Danger time delay can be set at one second intervals (from1 to 60).
The Danger time delay can be set for up to two availableproportional values.
If the 100 ms option is on ():
The Danger time delay is set to 100 ms (Typ.).
The Danger time delay can only be set for the primaryproportional value.
3.3 Available SetpointsThis section specifies the available setpoints for the Aeroderivative Channel. Asetpoint is the level within the full-scale range that determines when an alarmoccurs. The 3500 Monitoring System allows Alert/Alarm 1 setpoints to be set forevery proportional value on each channel. The channel will drive an Alert/Alarm1 indication if one or more of the channel proportional values exceeds itssetpoints. The 3500 Monitoring System also allows up to four Danger/Alarm 2setpoints (two over setpoints and two under setpoints) to be set for up to two ofthe proportional values. You may select any two of the available proportionalvalues for the channel if the 100 ms delay has not been selected.
NoteThe setpoint over and under limits can only be placed within the OK Limits ofthe specified transducer.

5.1.5.2 Test Alarms - Aeroderivative
The general approach for testing alarm setpoints is to simulate theAeroderivative signal with a function generator and power supply. The alarmlevels are tested by varying the output from the test equipment and observingthat the correct results are reported in the Verification screen on the test
computer. The same test alarm procedure is used for Direct and Band-pass. Itis only necessary to test those alarm parameters that are configured and beingused. The general test procedure to verify current alarm operation will includesimulating a transducer input signal and varying this signal:
1. to exceed over Alert/Alarm 1 and Danger/Alarm 2 Setpoints and
1. to drop below any under Alert/Alarm 1 and Danger/Alarm 2 Setpoints and
1. to produce a nonalarm condition.
When varying the signal from an alarm condition to a nonalarm condition, alarmhysteresis must be considered. Adjust the signal well below the alarm setpointfor the alarm to clear.

5.1.5.5 Calculating the Input Voltage for Full-scale
The procedure for verifying channel values require that you use the followingformulas to calculate the input voltage for full-scale. To find the full-scale input
voltage, use the appropriate formula for integrated or non-integrated units.
Full-scale - No Integration
To find the full-scale value for the configured full-scale range, input theconfigured full-scale range and transducer scale factor into the formulas shownin the table below:
NoteUse the Transducer Scale Factor displayed in the Scale Factor Box on theVerification Screen.
Full Scale Formulas
Units To Input RMS

mm/s
peak
(T.S.F x Full-Scale) x
0.707
(T.S.F x Full-Scale) x 2
T.S.F. = Transducer Scale Factor. To use the formulas, the T.S.F shouldbe in volts and the T.S.F. and full-scale values should both be of the sameunit system (metric or English).
Example 1:
Transducer Scale Factor = 100 mV/(in/s)Full Scale = 2 in/s pk
For Peak to Peak input:( 0.100 X 2 ) X 2 = 0.4 V pp
For V rms input:( 0.100 X 2 ) X 0.707 = 0.1414 V rms
