PT2060/10 Module Introduction

General Information

ProvibTech’s PT2060/10 PROX proximity module is a four channel proximity signal conditioner, and processing unit. This module should be assembled in the PT2060 rack to fulfill its function.

The PT2060 System Configuration software is used to configure the module’s type, and set its parameters and display information including active value.

Each channel on the PT2060/10 PROX proximity module can accept any proximity probe system signal input, process it, and output the processed data. The PT2060 System Configuration software performs the configuration of parameters for the PT2060/10 PROX module, and collects information on module including proportional value and GAP voltage.

Note : For speed measurement, optional magnetic pickup sensor is available.

PT2060/10 PROX proximity module can realize the following functions:

9 Shaft Vibration (4 channels)

9 Axial Thrust Position (4 channels)

9 Differential

9 Eccentricity (2 channels)

9 Low Frequency Vibration (4 channels)

9 Speed

9 Zero

9 Reverse rotational protection output (2 channels)

Shaft Radial Vibration

For rotating machinery monitoring, radial vibration is one of the fundamental parameters of indication machine running status. Many machine malfunctions, such as rotor imbalance, misalignment, bearing wear, shaft cracks and shaft rubs may cause significant vibration change.

Axial Thrust Position

Figure 1

Axial thrust position is the most important monitored parameters on many machines including steam, gas and hydro turbines, centrifugal and axial compressors, and centrifugal pumps. Excessive axial thrust position movement can lead to extensive machine damage.

The PT2060/10 PROX proximity module provides early warning of thrust bearing failure. While accepting inputs from proximity probe transducer systems, it continuously measures and monitors one to four independent channels of axial shaft position relative to the axial clearances within the machine. It is recommended to mount two probes to measure shaft position. This will maximize the reliability of shaft position measurement.


4


Differential Expansion

In turbine machinery monitoring, differential expansion is one of the important factors in machine running status indication. The excessive thermo expansion of the rotor and the stator may cause machine failure.

PT2060/10 PROX proximity module can be configured to measure turbine thermo differential expansion.

Eccentricity

Eccentricity is very important for monitoring turbine rotor bow. PT2060/10 PROX proximity module can provide sophisticated on-line eccentricity monitoring. The monitor is suitable for virtually all types of rotating machinery in terms of eccentricity. The PT2060/10 PROX proximity module will be continuously measure and monitoring in up to two channels per module.

Eccentricity measurements indicate the deviation of the rotor physical center and the theoretical center. The difference has to be small enough to allow machine startup without causing damage. The PT2060/10 PROX proximity module provides peak-to-peak eccentricity measurement, which measure the difference between the positive and the negative extremes of the rotor bow. It also has one more channel that output the position of the rotor.

Warning

To measure eccentricity, phase reference channel must be available.

Low Frequency Vibration/Hydro Vibration

This is a general channel to measure low frequency vibration. This mode is applied whenever phase reference is not available.

Possible application includes hydro-turbine oscillation. Hydro turbine shaft oscillation is usually a low frequency oscillation. Excessive oscillation will damage the turbine.

Speed, Reverse Rotation Speed Output and Zero Speed

Rotor speed is important measurements during normal machine operating conditions as well as during startup and coast down. Sudden unexpected changes in rotor speed may be an indication of machinery or process malfunction.

Many machines require a turning gear be used to prevent rotor bow while the machine is off-line. It is essential that the rotor speed of operation has dropped to a specified value, which is zero speed. PT2060/10

PROX proximity module continuously measures shaft speed, and zero speed indication.

Zero speed will have two output channels. It will include both zero speed and speed measurement.


5


For some machine, reverse rotation will damage the machine. PT2060/10 has option to configure the module to reverse rotation monitor. This mode requires two sensors for one channel. The reverse rotation monitor will output alarms for machine reverse rotation, it also include all the function of the speed channel.

Triple Modular Redundant (TMR)

Three PT2060/10 PROX proximity modules and one PT2060/43 R-RELAY Redundant-Relay module constitute a TMR (Triple Modular Redundant). The TMR system’s main function is that the PT2060/43

R-RELAY module processes alarm signals from the three PT2060/10 PROX modules and outputs synthetic alarm according to an assigned logic. Each module in the TMR system works independently and functions the same as in non-redundant system. This system can provide alarm message to field operators and the host computer.

A standard 19″ PT2060 rack can contain maximum three sub-systems. Each system has to be on slot 1-4, slot 5-8 and slot 9-12. PT2060/43 R-RELAY module can be mounted in slot 4, 8 and 12 only. Three

PT2060/10 PROX modules must be assembled in three adjacent slots, slot 1-3 for example, together with a

PT2060/43 R-RELAY module assembled in slot 4 to constitute a TMR system. A 12″ PT2060 rack has one TMR system only. It can be mounted slot 1-4. For more information, please refer to

PT2060/43 R-RELAY Redundant-Relay Module User Manual .

Other Information

PT2060/10 PROX proximity module has four channels on it. Channel 1 and 2 must have the same channel type. Channel 3 and 4 must have the same channel type too. The channel types of channel 1, 2 and channel 3, 4 may be different. For example, channel 1, 2 can be set to shaft vibration; channel 3, 4 can be set to rotational speed.

PT2060/10 PROX proximity module also supports alarm multiply (only for shaft vibration and low frequency vibration) and alarm bypass functions. Alarm multiply will increase the alarm setup to a factor of two or three depend on configuration setting. Alarm bypass will prohibit the module’s alarm engagement.

Any proximity probe system can be interfaced with our PT2060/10 PROX proximity module. Most commonly used proximity probe systems include 5mm, 8mm, 11mm, 25mm and 50mm probes.

Such as TM0105 series 5mm probes, TM0180 series 8mm probes, TM0110 series 11mm probes, and TM0120 series 25mm probes. PT2060/10 PROX proximity module can also interface with other manufacture’s proximity probe systems, such as 3300XL series 5mm, 8mm and 11mm probe. 7200 series 5mm, 8mm and 11mm probe. 3300 and 7200 series of 25mm, 50mm probes.

When PT2060/10 RPOX module is used to measure speed, it can connect to magnetic pickups.

The major task for PT2060/10 PROX proximity module is to process the input signal, compare Figure 2 the overall with the alarm set-point and output the appropriate status information. It can also output much more information to the field operator and upper-level control system, such as GAP, module

Module Configuration and Channel Set-up

PT2060/10 PROX proximity module is capable of processing most signals coming from proximity probes, such as shaft vibration, shaft displacement, eccentricity, differential expansion, low frequency vibration, rotational speed, zero speed and reverse rotation. When PT2060/10 RPOX module is used to measure speed, it can connect to magnetic pickups too. To fulfill these functions, PT2060/10 PROX modules and

PT2060 System Configuration software are needed to work together. In this chapter, the description of the configuration setting is based on PT2060 System Configuration.

Hardware Configuration

Each PT2060/10 PROX proximity module occupies one slot in the rack. A standard 19″ rack can contain up-to twelve PT2060/10 PROX modules. PT2060/10 PROX modules can be mounted in any slot from 1 through 12.

A 12″ rack can contain up-to 6 PT2060/10 PROX modules. PT2060/10 PROX modules can be mounted in any slot from 1 through 6. If customers want to realize redundant, the modules should be installed in certin adjacent slot groups according to the redundant requirement.

To configure PT2060/10, communication between PT2060 System Configuration software and PT2060/10 module has to be established. This communication is normally setup via. PT2060/91, the system interface module. As Figure 4 shows, Computer will connects PT2060/91, the System Interface Module via the RS232 on the front panel or RS485 or RS232 on the back panel.

Module Function Description

Alarm Type

PT2060/10 PROX proximity module has two alarm status, alert and danger.

Alert can be configured to one of the two alarm types, Alert and Gap, if the chosen type is Alert, in Real-time value and Status window of PT2060 System Configuration software, the column Alert indicates whether it is in alert status, and the column Danger indicates whether it is in danger status. If the chosen type is GAP, in the software window, the column Alert indicates whether the GAP voltage exceeds the assigned value and the column Danger indicates whether it is in danger status.

GAP not OK

When a certain channel of PT2060/10 PROX proximity module has GAP voltage exceeding the setting range, it will turn to GAP not OK status, and the OK / IO LED will be off.

If the current channel’s alarm type is Alert, When GAP is not OK, it can be seen from Real-time Value and

Status interface of PT2060 System Configuration, that:

9 Real time value equals to fill scale low limit

9 GAP value is normally displayed, is the current GAP voltage

9 Alert is False, Danger is False (alarm latching has higher privilege than GAP not OK. If before turning to

GAP not OK, alarm latched already, Alert and Danger will not change).

Besides, the channels’ output current ought to be set to 3.0±0.16mA.

If the current channels’ alarm type is GAP, when GAP is not OK, it can be seen from Real-time Value and

Status interface of PT2060 System Configuration, that:

9 Real time value equals to fill scale low limit

9 GAP value is normally displayed, is the current GAP voltage

9 Alert is True, indicating that it is in GAP not OK status

9 Danger is False (alarm latching has higher privilege than GAP not OK. If before turning to GAP not OK, it has Danger latched already, Danger will not change)

Besides, the channels’ output current ought to be set to 3.0±0.16mA.

Bypass

There are two types of bypass, hardware bypass and software bypass. When hardware bypass is activated, the Bypass LED on (When software bypass is activated, the LED does not come on). Both types of bypass do not affect monitor performance except the alarms. Bypass will inhibit Danger alarm, Alert alarm. The default status is inactive. Bypass has a higher privilege than alarm latch does.

A channel bypass status may result from the following conditions :

9 PT2060/10 PROX proximity module has never been configured

9 PT2060/10 PROX proximity module is in configure mode


16


9 Channel of PT2060/10 PROX proximity module has an invalid configuration

PT2060/10 module also supports alarms trip-multiple (applying with shaft vibration and low frequency vibration only).

Trip-multiply will temporarily increase the alarm (Alert and Danger) set-points. Trip-multiply is normally applied by manual (operator) action during startup to allow a machine to pass through high vibration ranges without trigger monitor alarms. Such high vibration ranges may include system resonances and other abnormal transient.

The function of trip-multiply is fulfilled through software under the hardware control i.e. the software multiply function takes effect only after a multiply terminal has been plugged in the socket on the PT2060/91 SIM

System Interface module. When alert alarm type is Alert, this function is valid for both alarm levels alert and danger. When alert alarm type is GAP voltage, this function is valid for danger. When double multiply is set, alarm occurs after real-time value reaches two times higher than or equal to alarm set-point value; When triple multiply is set, alarm occurs after real-time value reaches three times higher than or equal to alarm set-point value. The default status is inactive.

Channel Disable

When Channel is un-used, it should be disabled. In this case, from the window Real-Time Value and Status it can be seen that GAP not OK, Alert and Danger turn false and GAP value becomes 10.0V. Real time value is full scale low. Or zero for position and temperature channels.

Redundant

A redundant system consists of three PT2060/10 PROX modules and a PT2060/43 R-RELAY module. Any

PT2060/10 PROX module in this system works in the same manner as it does in independent mode. Please refer to PT2060/43 R-RELAY Redundant-Relay Module User Manual for more details.

Vibration Module Type Setting and Parameter Configuration

PT2060/10 PROX proximity module supports proximity probe input, shaft vibration output. The proximity probe is mounted along the radial direction, i.e. the probe is perpendicular to the shaft. A PT2060/10 PROX proximity module can support 4 shaft vibration measuring channels. Typical full scale can be 100, 125, 200,

250, 500, 1000μm or 5, 10, 20, 40mil for 8mm probe.

The following parameters are required:

Channel Type

Proximity probe input, shaft vibration output

Transducer Type

PT2060/10 PROX proximity module can interface with many models of transducers such as,

TM0180/5m

TM0180/9m

TM0105/5m

TM0105/9m

TM0110/5m

TM0110/9m

3300/11mm/9m

7200/11mm/5m

7200/11mm/9m

Other 8mm Proximity probe transducer



Users could choose a proper one according to their application. TM0180/5m is the default transducer.

Transducer Sensitivity

This is the most important parameter that is corresponding to the transducer type and is given by the system.

User can also modify it manually. This value is typically expressed as millivolt per measure unit (for example mV/mil for displacement).When the transducer type is TM0180/5m, the default value is 8mv/μm.

Alert Time Delay, Danger Time Delay

It means how long the module will delay before changing into alarm status after having detected that real-time value exceeds or equals to the alarm set-point. The default value for Alert Time Delay is 3 seconds, and for

Danger Time Delay is 1 second. User can modify them from 1s to 60s as need.

Full Scale High, Full Scale Low

The high limit and low limit of the full scale. For shaft vibration, Full scale low is 0 by default. Full Scale high is determined according to the application. After these are set, the various alarm hysteresis values are determined. The default value is 1/64 of Full scale high.

Measurement Type

User can make his choice from the drop list. The default one is PK-PK.


19


Measurement Unit

PT2060/10 PROX proximity module can work with different measurement unit, metric or imperial. From menu item File->System Setup, open a new window as the figure below. The measurement unit is μm for metric or mil for imperial.

Figure 15

Alert Type

PT2060/10 PROX proximity module vibration monitoring mode supports two types of alarm, Alert and Gap.

Alert type means that the module outputs alarm when the real-time value exceeds or equals to alert set-point set by the PT2060 System Configuration software. Gap type means that the module outputs alarm when the gap voltage is above or equal to the Upper OK limit and below or equal to the Lower OK limit. Every channel of the module is capable of producing Alarm indication. These indications can be used in relay alarm drive logic which is configured in the Relay module. The default alert type is Alert.

Primary PR

A transducer that produces a voltage pulse for each turn of the shaft, called Phase signal. This signal is used primarily to measure shaft rotational speed and serves as a reference for measuring vibration phase lag angle. It is an essential element in measuring rotor slow roll bow or run out information. User will determine whether to correlate the real-time value with the phase reference and with which one, phase reference 1 or 2.

The default setting is NA. Primary PR is prior to Backup PR when redundant phase reference has been used.

Backup PR

The spare phase signal. The item can be set to NA or with Phase Reference 1 or 2. Primary PR and Backup

PR can constitute redundant phase reference in which Primary PR is used as the main phase reference signal and is firstly considered by PT2060/10, while Backup PR is used as the secondary phase signal to replace the Primary PR when it is not OK or lost. For example, when user selects with Phase Reference 1 for

Primary PR, with Phase Reference 2 for Backup PR, phase reference 1 is used as the phase signal firstly and is checked by PT2060. When PT2060/10 examines that Phase Reference 1 is lost or not OK, Phase

Reference 2 will be chosen to be the phase signal.

Channel Enabled

Channel Enabled lets you control whether or not the monitor channel is to use. (If the box is checked (√), the channel is in use). All of PT2060/10 PROX proximity module channels are checked by default. User could modify it if necessary.

Alarm Latching

Causes the PT2060/10 PROX proximity module to retain an Alarm status after the Alarm condition has gone away. The latching mode allows you to know if an alarm set-point has been exceeded since the last rack reset. Press the reset button on the rack SIM module will reset all latched alarms in the PT2060 rack if the current proportional value is less than the set-point value. You can also reset the rack by using the software


20


PT2060 System Configuration . The Event list for the monitor will provide information about faulted transducers even if non-latching is selected. The default status is latched and user can modify it.

Set Point

Shaft vibration alarm threshold is set here. There are two levels of alarm for shaft vibration mode. The value can be set to some certain percentage of FS. Default factory setting of Danger high is 75%, Alert high 50%.

Gap alarm has two levels too. Default factory setting of GAP high is -19V, GAP low -1V. When the alarm condition is satisfied, PT2060 goes in alarm status.

The value is related to the transducer type. When the transducer type is anyone of proximity probes, this value is set by the system and also can be modified manually. Default value is 8mv/μm. When the transducer type is magnetic pickup, it invalidates.

Teeth Per Cycle

Teeth number on the gear. The number of input pulses per shaft revolution when observing an integral multi-event signal source, such as a gear. The Events per Revolution may be specified as a number between

1 and 255 with four decimals . Default is 1 . User could set it according to the actual value in the field. For example, if there are 24 teeth on the gear, teeth per cycle can be set to 23.9998 to adjust the rotation speed slightly according to the need in the field.

Hysteresis Voltage

This is the voltage level above and below the threshold value which is required to "trigger" the input signal from the transducer. The larger the hysteresis, the greater the immunity to noise on the input signal. When the input signal passes the threshold voltage plus 1/2 of the Hysteresis voltage, the signal goes high. When the input signal returns to the threshold voltage minus 1/2 of the Hysteresis voltage, the signal goes low. The default value is 1V and user could modify it between 0.5-2.5V.

Trigger Voltage

The Trigger Value is the nominal voltage that the Hysteresis is centered about. The default value is -10V.

When the item Threshold Type is set to Manual, user could fill this manually or click the button Adjust to let the system get it automatically.


Could be set by user, the hysteresis value is always 10RPM.

And the default factory setting of GAP high is -24V, GAP low is -1V. When the transducer type is magnetic pickup, the GAP alarm is invalidates.

Threshold Type

The voltage level of the transducer signal where triggering occurs (if the Hysteresis voltage is 0).

Auto

The trigger threshold is automatically set to a value that is midway between the most positive peak and the most negative peak of the input signal. This value tracks any changes in the input signal. Auto threshold requires a minimum signal amplitude of 1 V pp and a minimum frequency of 0.0167 Hz.

Manual

The trigger threshold is set by the user to any value in the range of -8 to -14 volts. Manual threshold requires a minimum signal amplitude of 500 millivolts peak to peak.

Rotative Speed Alarm Type

Two types: Over rotative speed alarm, Over and Under rotative speed alarm.

Over

Two level high alarm: danger high and alert high. If selected, the item Set Point is present to be Danger

High and Alert High. When the real-time value is higher than or equal to alert high or higher than or equal to danger high, alarms occurs.

Over And Under

One high alarm, one low alarm. If chosen, the item Set Point will turn to High and Low. Alert alarm occurs when real-time value is lower than or equal to the Low set point. Danger alarm occurs when the real-time value is higher than or equal to the High set point, It does not alarm when real-time value is between High and

Low set points.

Zero Speed Mode Type and Parameter Configurations

PT2060/10 PROX modules support Zero Speed output mode and can also be used to monitor shaft rotational speed.

Working in this mode, channel 1 and 2 are combined together in a group. And channel 3 and 4 are tied together to form another group. Only channel 1 and 3 have transducers connected to them. When the shaft rotational speed is less than 100RPM, the two-output channels in one group output real-time value. Channel one is for Zero measurement only. Thus, it has higher accuracy, and been used to trigger alarms. When the shaft rotational speed is higher than 100RPM and less than 60000RPM, the first channel constantly outputs

100 RPM and the second channel outputs the real-time value. The status of the item Channel Enabled and

GAP not OK are the same for the two channels.

Typical full scale of channel 1 can be set to 100 RPM, and channel 2 can be set to 1000, 3000, 3600, 6000,

10000RPM.

Zero speed mode type can cover speed measurement. But speed measurement can not cover Zero speed.

For channel 1, alert low and danger low. If selected, the item Set Point is present to be Alert Low and

Danger Low. When the real-time value is lower than or equal to Alert Low or lower than or equal to Danger

Low, alarms occurs. For channel 2, the same to Rotative Speed Alarm Type.

Over And Under

For channel 1, One high alarm, one low alarm. If chosen, the item Set Point will turn to High and Low.

Alert alarm occurs when real-time value is higher than or equal to the High set point. Danger alarm occurs when the real-time value is lower than or equal to the Low set point, It does not alarm when real-time value is between High and Low set points. For channel 2, the same to Rotative Speed Alarm Type.

Reverse Rotational Speed Mode Type and Parameter Configuration

PT2060/10 modules support Reverse rotational speed output measuring mode. In this mode, it is divided into two groups. Channel 1, 2 constitute one group and channel 3, 4 constitute another group. Channel 1 and 3 are normal speed channel. Their full-scale range can be set to 100, 1000, 3600, 6000, 10000RPM. When the shaft rotational speed is less than 100RPM (in the periods of starting and stopping), the module output the real-time value according to the direction of rotation. Note, that the reverse rotation is named relatively to forward rotation based on which channel is taken as the criterion. For example, when Leading Transducer is set to channel 1 and the signal of channel 2 lags the signal of channel 1, it is named forward rotation; otherwise, reverse rotation. When Leading Transducer is set to channel 2 and the signal of channel 1 lags the signal of channel 2, it is named forward rotation; otherwise, reverse rotation.

Two proximity probes are required in a group. The module analyses the rotation direction at power on. If it is forward rotation, the first channel outputs the real-time rotational speed and its output current is corresponding to its speed; Channel 2 gives 0 as its real-time value and output 4mA current constantly.

Channel 1’s alarm status is the same to that of rotational speed. Channel 2 has no alarm. If it is reverse rotation, channel 2 outputs the real-time rotational speed and outputs current corresponding to its speed;

Channel 1 gives 0 as its real-time value and outputs 4.0mA current constantly. Alert alarm is setted, danger alarm status is determined by the comparison of real-time value and danger alarm setpoint.

Therefore, when it is forward rotation, the measured message is mainly shown through channel 1; when it is


36

PT2060/10 PROX Proxinity Module reverse rotation, the measured message is mainly displayed through channel 2. For forward rotation, there are two kinds of alarm: two level alarms and one high alarm, one low alarm and the alarm runs in the same way as that of speed channel type. Reverse rotation is different from speed channel type, Alert status only indicates reverse rotation direction. The alarm status could be seen from the Real-time Value and Status window of the software PT2060 system configuration and from the Alarm LED on PT2060/10-Front panel.

The reverse alarm means that it outputs alarm when the signal is in reverse rotation state which can be seen form the Real-time Value and Status window of the software. The Alert value turns true, that means it is in reverse rotation state. Accordingly, the Alarm LED on PT2060/10-Front panel is on. When the Alert value in the software window turns False, it means that the signals are in forward rotation state.

In a group, the item Channel Enabled of the two channels is configured with the same status. Besides one channel is GAP not OK, so does the other one.

PT2060/10 PROX proximity module reverse rotational speed full scale can be set to 100, 1000, 3600, 6000,

10000RPM.

The following parameters are required.

Field-wiring Diagram for Reverse Rotation Measurement and the Theory

Figure 39

Reverse rotation measuring needs two proximity probes in pairs. The connection of each transducer to the

PT2060/10 PROX proximity module is the same as described above. The probes may be mounted as shown in figure above.

Two probes are located in radial direction. The angle of the two probes may be adjusted according to the filed situation. Two probes must be mounted on the shaft with a distinction between them to make there are not interference between them.

After installing the two probes and connecting to PT2060/10 PROX proximity module, Power on the system.

Choose which one is used as the criterion to estimate lead or lag of the signals via the software PT2060 system configuration. Refer to the relevant part of Configuration Setting and Application for operations.

Warning

The system has to be verified before running to determine the leading probe.

It is necessary to ensure the system working in forward rotation status.

If it not, please exchange the two probes station or define the other channel as forward channel.

Module Test

A PT2060/10 PROX proximity module can accept signal from proximity probes only, no matter what type it works in (Shaft Radial Vibration, Axial Thrust Position, Differential Expansion, Eccentricity, Low Frequency

Oscillation, Speed, Zero Speed, reverse rotation). The maintenance steps are all alike, except a bit difference in details.

Warning touch exposed wires or terminals.

High voltage! Contact could cause shock, burns, or death. Do not

Application Alert

Tests will exceed alarm set-point levels causing alarms to activate.

This could result in a relay contact state change.

Application Alert

Disconnecting field wiring will cause a not OK condition.

Shaft Vibration

Determine the tested group, channel 1 and 2 for example. Plug the terminal into the port of channel 1 and 2 on the rear panel. Plug the black pen of a multimeter into port COM and the red pen of multimeter into OUT port, OUT1 for channel 1 for example. Set the multimeter to measuring direct current. Connect the positive pin


54

PT2060/10 PROX Proxinity Module of the electrolytic capacitor (220μF/50V) of the terminal to a signal generator’s output. Connect related BUF located on PT2060/10-Front panel to an oscilloscope. Connect phase reference terminal if necessary. Run the software System Configuration.

2. Test of powering on

On powering, OK / IO LED and Alarm LED should be on for 3s or so that indicates that the channel is operating correctly.

3. Test of communication

Click the button Upload on the software System Configuration main rack window to upload the parameters. If succeeded, please save these parameters to a file as the original data for recovery. If failed, please check communication cable and baud rate setting.

4. Test of parameter setting

Click on the picture of the tested module to open its configuration window where you could make some modifications. After that, you could download it and re-upload it again to compare whether they are changed correctly.

At the end you should restore all of the original setting.

5. Test of OK status

Observe the changing of OK / IO LED as you adjust the potentialmeter of the terminal plugged into the signal input terminal (It flashes only when all enabled channels on the module are OK). When the OK / IO LED went off, the output current is about 3.0 ±0.16mA which you could read from on the ampere meter

6. Test of linearity

Feed a channel with some certain magnitudes of signal at the frequency actually used in the field according to the following table. Measure the output current with an ampere meter. If the linearity does not satisfy the requirement, please re-calibrate it (refer to the next section).

Percentage of full scale 0% 25% 50% 75% 100%

4～20mA (mA) 4.00±0.16 8.00±0.16 12.00±0.16 16.00±0.16 20.00±0.16

Notes : Corresponding to the full scale 1000μm, the input signal should be at 8V/80Hz. If the current channel’s full scale is 0-400μm, the signal given from the generator should be at 0-3.2V.

7. Test of alarm

Like the linearity test, provide a signal to channel 1 or 2, adjust the magnitude of the signal and observe the variation of alarm LED and check whether it light when any alarm threshold is broken and whether the variation of alarm status can be seen in Real-time Value and Status window.

If alarm latch is not set, the alarm will be reset as soon as the input signal is removed. Otherwise, it will be latched and can be reset only by pressing RESET button located on PT2060/91-Front panel (or clicking the menu item Rack->Rack Reset Setup of the software). Check whether it was reset from Real-time Value and

Status window. Any channel’s alarm of the module will light up the alarm LED and make the module change to alarm status. Besides, the alarm hysteresis also takes action in this process.

8. Test of BUF

If it is required, user could conduct BUF test. Adjust the input signal and check the buffered output with an oscilloscope whether they are compatible. Tune the potentialmeter to make its output at -10V or so and observe the buffered output with an oscilloscope. The noise signal PK-PK value should be less than 50mV.

The figure below shows how to connect an oscilloscope to BUF.


55


Figure 42

9. Test of software bypass

Checking the Channel Bypass switch will cause the module to indicate a "bypass" status. This feature should be used if you wish to temporarily disable a channel on a module. In Signal Module status Control window of the software, select slot number and channel number and tick Alert Bypass and/or Danger Bypass as you need. Download it by clicking the button Download. Supply a signal higher than alert or danger set-point at this hour and no alarm will occur, i.e. specified channel’s alarm status is bypassed.

10. Test of hardware bypass

Feed a signal higher than alert or danger set-point to a channel. Plug the prepared bypass terminal in the socket located on the back panel of communication module. Bypass LED of the PT2060/10 PROX proximity module should light up and the Alarm LED should go off. Meanwhile, the alarm mark in the Real-time Value and Status window of the software vanishes. Unplugging the bypass terminal, the alarm reappears.

11. Test of multiply logic

In Signal Module status Control window of the software, select slot number and channel number and check none or Double Multiply or Triple Multiply as you need. Download it by clicking the button Download. Plug the prepared multiply terminal in the socket located on the back panel of communication module. Feed the channel with a signal. Merely when the magnitude of the signal is as high as double or triple of alert or danger threshold, the alarm occurs.

12. Test of voltage

Normal voltage is critical for measuring. Measure the channel voltage as shown in the figure below. It should be at about -24V for its normal operation.

13. Test of redundant power

Feed channel 1 with a signal corresponding to 50% of Full-Scale. At this time, the output current of this channel is about 12.00±0.16mA. Pull out the lower power module and the output current should keep in this range. Push the lower power module and pull out the upper one, and the current should be stable too.

Shaft Position

The measuring of shaft position has no relation to phase reference, so the phase reference terminal and the signal generator are not needed. See shaft vibration for others.

2. Test of power on

See shaft vibration part.








Tune the potentialmeter and check whether the current output suffices the linearity requirement according to the following table. If it does not, perform current calibration with the channel (see the next section).


4～20mA (mA) 4.00±0.16 8.00±0.16 12.00±0.16 16.00±0.16 20.00±0.16

Notes : When transducer direction is Toward Probe, corresponding to proximity probe’s output voltage ranges of -2V and -18V. If the full scale is set to -1000μm and 1000μm respectively, then -2V corresponds with

1000μm and -18V corresponds with -1000μm.

7. Test of alarm

It should be paid more attention that there are four alarm levels for shaft position measuring mode. The signal is provided by tuning the potentialmeter.

8. Test of BUF

See shaft vibration part if it necessary.


57






11. Test of voltage




Differential Expansion

Its procedure is the same as the procedure of maintaining shaft position.

Eccentricity

Plug a phase reference terminal into the port located on PT2060/91-Back. Provide a signal with a prepared signal generator. Refer to the relevant part of PT2060/10 PROX proximity module Configuration Setting and

Application and PT2060/10 PROX proximity module functions and configuration setting please. Conduct the test steps as what have done in shaft vibration test.

Notes : the electrolytic capacitor for this is 1000μF/35V. Merely channel 1 needs signal.

2. Tests of power on









According to the assigned full scale and the frequency in the field, provide the first channel a signal with a function generator. The frequency of the phase signal is the same to that of signal generator. Adjust the amplitude of the signal and check the current output of the first channel, whether its linearity suffices the requirements listed in the following table. Adjust the potentialmeter and check the current output of the second channel whether its linearity suffices the requirements. If it does not, recalibrate it. (See the next section.)


4～20mA (mA) 4.00±0.16 8.00±0.16 12.00±0.16 16.00±0.16 20.00±0.16

7. Test of alarm

Like linearity test, provide a signal to channel 1. Adjust the magnitude of the signal. If channel 1 or channel 2 alarms, the alarm LED on the PT2060/10-Front should come on. The alarm status could be seen in Real-time

Value and Status window.

If the alarm is not latched, the alarm status will reset as the signal is removed. Otherwise, it can be reset only by pressing the RESET button on PT2060/91-Front (or by clicking the software item Rack->Rack Reset


58


Setup ). The alarm LED is to light up, when anyone of the channels turns to alarm status.

The alarm hysteresis also takes part in this.

8. Test of BUF

See shaft vibration part if it necessary.





11. Test of voltage




Low Frequency Vibration

An electrolytic capacitor of 1000μF/35V is used on the terminal for Low frequency vibration test. The test procedure is the same as the procedure for shaft vibration test.

Speed

If transducer type is anyone of proximity probes, take one proximity terminal. Plug the terminal into the

PT2060/10-Back panel. Connect the red pen of an ampere meter to OUT pin of the current output port and connect the black pen to GND pin on that port. Set the ampere meter to measure direct current. Feed a signal to the channel through the positive pin of the electrolytic capacitor (220μF/50V) of the terminal. Connect an oscilloscope to the BUF.

If transducer type is magnetic pickup, take one magnetic terminal. Plug the terminal into the PT2060/10-Back panel. Connect the red pen of an ampere meter to OUT pin of the current output port and connect the black pen to GND pin on that port. Set the ampere meter to measure direct current. Feed a signal to the terminal.

Connect an oscilloscope to the BUF.

Turn on the PC and invoke the configuration software.

2. Test of power on


3. Test of system communication



This is related to the first channel only.



If transducer type is one of proximity probes, tune the potentialmeter (10kOhm) of the terminal plugged in the first channel. Observe OK / IO LED status (it flashes only when all enabled channel are OK). When the potentialmeter is out of the assigned OK range, the OK / IO LED will go off. At this time, the output current is

3.0 ±0. 16mA.

If transducer type is magnetic pickup, the channel has no relation to OK / IO LED.


59



PT2060/10 PROX proximity module speed measure is related to the first channel and the third channel only.

Provide a signal to that channel according to the following table. Check whether its linearity suffices the requirement or not. If not, perform calibration again.


4～20mA (mA) 4.00±0.16 8.00±0.16 12.00±0.16 16.00±0.16 20.00±0.16

Notes : Provide a signal of magnitude of 8V and tune its frequency according to the full scale. If the full scale is

0-6000RPM and teeth per cycle is 1, the frequency range is 0-100Hz.

7. Test of alarm

Like the linearity test, feed channel 1 with a signal generator. If a channel becomes alarm status, the alarm

LED on the PT2060/10-Front panel should come on. The alarm status could be seen in Real-time Value and

Status window.

If the alarm is not latched, the alarm status will reset as the signal is removed. Otherwise, it can be reset only by pressing the RESET button on PT2060/91-Front panel (or by clicking the software item Rack->Rack Reset

Setup ). The alarm LED is on, when anyone of the channels turns to alarm status.

The alarm hysteresis also takes part in this.

8. Test of BUF

If necessary, users can perform BUF testing.

Tune the signal generator and monitor the BUF output with an oscilloscope which should be conformable with the input one.

If transducer type is one of proximity probes, adjust the potentialmeter to make it outputs a voltage of about

-10V and check the BUF output noise which should be less than 50mV.

If transducer type is magnetic pickup, check the BUF directly, the output noise should be less than 50mV.





11. Test of voltage




Zero Speed

An electrolytic capacitor of 1000μF/35V is used on the terminal for zero speed testing. The test procedure is the same as the procedure for shaft vibration test. Parameter setting refers to zero speed type part.

Reverse Rotation

Insert vortex analog terminals to two reverse rotational channels in one group. Choose electrolysis capacitance 220μF/50V. Use two multimeters to measure current, connect the red pen of the multimeter to

OUT pin, black pen to GND pin of current output terminal. Tune the multimeter to measure direct current.


60


Supply signal through the positive pole of electrolytic capacitor 220μF/50V on the terminal(measure tool).

Connect oscillograph to BUF terminal.

2. Test of system power on

Refer to speed part.



4. Test of parameter configuration

Channel 1 and 2 need to be set simultaneously. Refer to reverse rotation part.




According to full scale and the frequency in the field, provide the module two signals which have the same frequency and different phases, as shown in the figure below.

Figure 44

Make sure that the Leading transducer is CH1, which means that the rising edge of the signal of the first channel is used as criterion.

If the signals provided to channel 1( Probe A used as the sensor) and 2( Probe B) are like the FORWARD in the figure above, at this time, the rising edge of the first channel is leading to that of the second. If the Teeth per cycle is set to 60, the real-time value of the first channel equals to the signal frequency and the output current is its proportional value. The second channel shows zero and outputs a current of 4mA. While keeping the phase relation of the signals, adjust their frequency to verify the linearity, check whether it is satisfied.

If the rising edge of the second channel is leading to that of the first, as the above REVERSE figure shows, the target rotates reversely. If the teeth per cycle is set to 60, the real-time value of the second channel equals to the signal frequency and the output current is proportional to the value. The first channel shows zero and outputs a current of 4.0mA. While keeping the phase relation of the signals, adjust their frequency to verify the linearity, check whether it is satisfied.

Notes : The amplitude of the provided signals is normally 8V. Change the frequency as per full scale and teeth. If the full scale is set to 0-100RPM, teeth is set to 60, the signal frequency is within the range of

0-100Hz. If the Leading transducer is set to CH2, it means the rising edge of the second channel is used as criterion. The other functions are unchanged except alarm status.

7. Test of alarm

Like the test of linearity, provide signals to channel 1 and 2. When any alarm threshold is met or exceeded, watch the alarm LED whether it is on, verify whether the alarm status can be seen from Real-time Value and

Status interface of the software.

If the alarm is not latched, the alarm status is reset after the provided signal has been removed. Otherwise, it can be reset only by pressing the RESET button (or clicking “Rack->Rack Reset Setup item). Watch the status alternation from Real-time Value and Status interface of the sofware.

This part has also relation to alarm hysteresis.

Troubleshooting

Assessing PT2060/10 PROX proximity module status and troubleshooting in operations by analyzing the status of LED, System event list, Alarm event list are described in this chapter.

LED

LED located on the PT2060/10-Front panel are OK / IO LED, Alarm LED, and Bypass LED. They directly indicate the PT2060/10 PROX proximity module working status. If something abnormal, user could analyze it and solve some problems.

OK / IO LED

Flash: All enabled channels are ok. Digital communication is ok.

On without flash: All enabled channels are ok. No digital communication. This means there are problems in communication.

Off: One or more channels are not ok.

If OK / IO LED went off, the reasons may be: one or more channels’ GAP voltage is out of range; the connection of some transducer or the transducer itself is broken; If the first is the case, when it turns from

GAP not OK to OK status, there is a 15s delay for real-time value, alarm, 4-20mA current output. Try these to solve the problem: remount the module, reset it; check the probe and cable.

Alarm LED

On: One or more channels have alarms. When the alarm type is Alert, the alarms can be either alert or danger or both. When it is GAP, the alarms can be either GAP or danger.

Off: All channels on the module are in normal status. No alarms engaged.

If Alarm LED does not work normally, it may be caused by these: the module is failed; the transducer and the cable. Try these to solve it: remount the module; reset it; check the probe and cable.

Bypass LED

On: PT2060 is in hardware Bypass mode. All alarms on this module are inhibit from alarms (no alarms will be engaged). Module’s real-time value and current outputs are not affected.

Off: Normal operation mode. If it does not light after bypass terminal inserted, the bypass led does not work normally.

If Bypass LED does not work properly, it may be caused by these: PT2060/10 PROX proximity module or

PT2060/91 SIM System Interface module is in an abnormal condition. In this case, please contact with a

ProvibTech local office.


65


Real-time Value and Status

From Rea-time Value and Status window, as shown in the following figure, user may unveil some problem.

Alert

False: When alarm type is Alert, it means there is no alert. When alarm type is GAP, it means there is no

GAP alarm.

True: When alarm type is Alert, it means there is an alert. When alarm type is GAP, it means there is a

GAP alarm.

Danger

False: It means there is no danger alarm no matter what alarm type is.

True: It means there is a danger alarm no matter what alarm type is.

GAP not OK

False: The channel is OK.

True: The channel is GAP not OK. The reasons may be: a. the sensor’s GAP is out of range; b. the connection may fail; c. the sensor is damaged. If the reason is a, there will be a delay of 15s, when it turns from GAP not OK to OK status.

There is some information about making Test Terminals.

Terminal for Proximity Probe

If the channel is to connect with a proximity probe, the terminal should be made following these steps.

Take an 8 pin plug (centre distance 3.8mm) as shown in the figure below. Solder the movable pin of a potentialmeter of 10kΩ and the negative pin of an electrolytic capacitor of 200μF/50V or 1000μF/35V together and then connect it to the SIG pin of the plug. Connect the other two pins of the potentialmeter to PWR and

COM respectively. Left the positive pin of the electrolytic capacitor float through which the signal will come in.

Figure 53

Terminals for Magnetic Pickup

Take an 8 pin plug (pin distance 3.8mm) like what is shown in the figure above and two short wires. Connect one wire to SIG, and other wire to COM.

Phase Reference Terminal

If the channel needs phase reference signal, the terminal should be made following these steps.

Connect the movable pin of a potentialmeter to the PH-REF1 pin of a pin plug (pin distance 3.8mm). Solder the negative pin of an electrolytic capacitor to the movable pin of the potentialmeter. Connect the other two pins of the potentialmeter to -24V pin and COM pin. When the phase reference is needed, feed a signal to the float positive pin of the electrolytic capacitor. In the manual trigger mode, the phase signal magnitude should be greater than 0.5V(PK-PK）and above 1 RPM(0.017Hz). User can select trigger voltage from -17~-3V; in the auto trigger mode, the signal magnitude should be greater than 2V(PK-PK) and above 120 RPM (2 Hz) .
