Shaft Vibration Monitor
1GB SHAFT VIBRATION MONITOR
The two−channel Low Frequency Shaft Vibration Monitor A6151 is a module of the A6000
machine monitoring system. The micro−processor controlled monitor is used in conjunction with
two eddy current measuring chains to measure and monitor the relative shaft vibration of hydro
turbines.
The two channels of the monitor can be used as separate channels or they can be linked together
via the configuration. The following operating modes are possible:
•Dual channel operation.
•The calculation and output of the maximum value Smax.
•The calculation and output of the greater vibration width SPPmax
The characteristic values can be output via a 0/4 ... 20mA current output per channel
i
In this product information the mounting and electrical connection of the
monitor is described. The configuration of the A6151 is similar to the
configuration of the A6110. Hence additional information concerning
configuration and installation can be found in the operation manual of the
A6110 (order number: 6110−90001) This operating manual is part of the
configuration software CD. All differences in installation and configuration are
described in this product information.
To ensure the safe operation of the monitor and to permit setting of all
functions, it is indispensable to use only the latest versions of configuration
software (version 2.07 Beta 78) and operating manual.
The use of old operating manuals or configuration programs out of date may
lead to malfunctions or limitations of the measuring functions.
1.1 Scope of Delivery
The following parts are included in the scope of delivery and must be contained in the shipment:
•Low Frequency Shaft Vibration Monitor A6151
•This product information

1.2 CSA Certification
STOP
For valid CSA certification, all devices (IMR 6000/xx and A6000 modules)
must be marked with the respective CSA lable.
If no CSA lable is available on the respective device, this device is not CSA
certified!
The respective CSA lable looks as shown in the following picture.
1.3 CSA −Conditions of acceptability
This device must be supplied with safety low voltage SELV LPS (C22.2 60950−1) 24V. The
voltage required for operation must be drawn from a separate power supply.
The system should be placed in a suitable fire enclosure.
The system is evaluated for an ambient Temperature of 0°C to 45°C.
Adequate ventilation space has to be provided so that heat does not build up. The ventilation
space must be at least 1 RU (13/4 inch) in all directions. If the ambient temperature of the rack
rises above 45 °C, cool this instrument with a forced air fan, cooler, or similar.
When mounting several IMR units above each other in one cabinet, install cooling fan racks in
between instead of the ventilation space. The necessary specifications for cooling fan racks
result from the environmental and sitting criterions of the cabinet and thus cannot be defined
generally.
1.4 Advice for Installation
STOP
According to the IEC 61010 directive, permanently installed systems must be
equipped with a power disconnect device (e.g. a switch or circuit−breaker
according to IEC60947−1 and IEC60947−3). When using an IMR rack, in
compliance with this directive, such a switch or breaker must be implemented
into the cabinet installation and easily accessible for the user. Furthermore,
each disconnect devices must be labeled in accordance to the associated
system.

1.5.1 Jumper RS 485
RS 485 bus operation requires an electrical terminator on the first and last bus device.
This is done with plug−in jumpers, that are on the controller board. The figure shows the position
of the jumpers.
To activate the bus terminator and to place lines “A” and “B” on the references, plug the jumpers
as shown in Fig. b). Fig. a) shows the jumper position for deactivated bus termination and open
references (delivery status).
•Plug−in jumper 1−2 closed: Bus line “B” via pull−down resistor on ground
•Plug−in jumper 3−4 closed: 120 Ωresistor between “A” and “B”
•Plug−in jumper 5−6 closed: Bus line “A” via pull−up resistor on +5 V

iFor trouble−free operation of the RS 485 bus, the lines “A” and “B” must be
connected on their references (+5 V, ground) in one monitor. This is only
possible if the bus termination jumper at this monitor has been closed as well.
1.5.2 Sensor raw signal
The raw sensor signal (unfiltered, in−phase output signal of the converter with AC and DC
portion) is applied to the front panel SMB sockets and can be fed to the terminals z14: channel
1 and z16: channel 2 of the connection strip with the jumpers J2. As delivered, the J2 jumpers
are set, that on terminals z14 and z16 the dynamic portion of the sensor signal (scaled to output
range 0 ... 20 Vss) is applied. The controller board must be removed in order to switch the signal
on the connection strip. The following points describe the procedure:
i
The reference point for the raw sensor signal from channel 1 is the connection
strip terminal z6: Supply1(+), and for the raw sensor signal from channel 2 the
terminal d6: Supply2(+). If these terminals are connected with terminal b10,
then the reference point is connected to system ground (GND). In this case
the terninals b22: GND and b24: GND can be used as reference point.
STOP
When working at the monitor, ensure that there is adequate protection against
electrostatic discharge. For example, wear an ESD bracelet to prevent
electrostatic discharge via the monitor electronics.
