four LED flashes. After releasing the button, you should see the
LED flash progressively slower until it completely stops, which
indicates the sensor is deactivated.
The sensor’s default network ID is 1229 from the factory, which
means it is ready to connect to the gateway as configured in the
previous section. The sensor has three optional network IDs from
the factory: 101, 102, and 1229. To reset it to the default 1229,
press the sensor’s button and hold it for nine LED flashes, then
release. After releasing the button, you should see a short burst of
quick flashes, which indicates the command was acknowledged.

p) The next task is to enable the Burst mode setting to burst the
response for the Cmd 3: Dyn vars / current query. Burst mode is
a special HART communication mode in which the sensor sends the
response of a query at a preprogrammed interval to the gateway,
without being polled. This reduces network traffic and stress on
the sensor firmware. When burst mode is enabled for Cmd 3, the
sensor sends overall velocity, acceleration enveloping, and
temperature measurements to the gateway at regular time
intervals, eliminating the need for the gateway to poll the sensor
each time the HART OPC server sends the Cmd 3 query. To
configure the burst mode, select the Burst Configuration / Burst
Message1 option from the left pane. The right pane updates to
show the current settings.

Troubleshooting
38 SKF Wireless Machine Condition Sensor Network
System Setup Guide
Troubleshooting
If new measurements are not updating to @ptitude Analyst, check the following:
Confirm the sensor is currently connected using the gateway’s Instrument List
web page.
In the Windows Task Manager, confirm the MAopcSrv.exe is running as a
process. If not, launch MAopcSrv.exe in C:\Program Files\SKF\MAOPCMGR
as detailed above. In the Windows Services, verify that MAopcSrv.exe is not
running as a service.
In the Windows Task Manager, confirm that Hartopc.exe is running. If not,
launch C:\Program Files\HART Server\Hartopc.exe.
Verify the OPC link using the @AOPC Manager.
Known Bugs
The SKF @AOPC client does not work as a windows service. The work around
is to launch it as a process.
The sensor LED may stop responding if, by press of the button, selecting the
reset command is immediately followed by selecting the shutdown command.
The work around is to wait at least 30 seconds between the reset and a shut
down.
Recovery Process
After a shut down, follow this procedure to restart the system:
Power up the gateway.
Turn on all sensors.
Power up the computer running the HART OPC Server and OPC client.
In the gateway’s web page, verify all sensors are connected.
Launch DevCom2000 to verify connection to the sensors. This step will
automatically launch the HART OPC server.
Stop @A OPC client running as a service and restart running as a process by
launching MAOPCSrv.exe manually.
Launch @Analyst to verify the system resumed collecting measurements.

Configuring the Network ID
The WirelessHART protocol allows only the network manager to modify the field
device’s network ID. Any attempt to change the network ID by a non-network
manager will result in getting an “Access Restricted” error code returned by the field
device.
In order to change the network ID in this first beta release, the user must use the
free telnet client, PuTTY.exe, to send the command through the CLI of the network
manager in the Pepperl+Fuchs gateway. You will find the PuTTY.exe file in the first
Beta release CD. Use the WirelessHART gateway IP address and Port 9000 to
connect to the CLI as a Telnet client, as shown below.

Installation of the SKF Wireless Machine Condition
Sensor
WARNING! Your safety is extremely important. Read and follow all
warnings in this document before handling and operating the equipment. You
can be seriously injured, and equipment and data can be damaged if you do not
follow the safety warnings. Refer to the beginning of this guide for important
safety messages.
Installation in Hazardous Locations
The SKF Wireless Machine Condition Sensor is certified for installation in safe areas,
and in ATEX Zone 0, 1, and 2 areas.
SKF Wireless Machine Condition Sensor Dimensions
The following features allow easy mounting and un-mounting of the SKF Wireless
Sensor:
Standard 1/4-28 UNF mounting hole threading
Robust metal base for applying mounting torque with 33.34 mm wrench
You can also access the SKF Wireless Sensor nut from top with a 100 mm long
socket wrench. See the figure below for sensor dimension details.
Error! Objects cannot be created from editing field codes.
Figure 53. SKF Wireless Machine Condition Sensor Main Dimensions.
Mounting Requirements
WARNING! Request a work permit from the site responsible Safety Officer
prior to commencing any installation work. Drilling is not allowed in ATEX Zone
0, 1, and 2 areas. Magnetic or adhesive mounting pads may be allowed.
The mounting configuration depends upon the dynamic measurement requirements,
such as frequency and amplitude range. Other factors to consider are mounting
location, prohibitions, accessibility, and temperature. In general, there are three
mounting configurations:
Magnets
Adhesives
Threaded studs
Installation of the SKF Wireless Machine Condition Sensor
Mounting Requirements
2 SKF Wireless Machine Condition Sensor Network
System Setup Guide
The mounting method affects the frequency range that can be measured; the less
rigid the method, the lower the maximum frequency.
Magnetic Mounting
Magnetic mounts are also popular in walk-around monitoring programs and the
frequency response is better, although still dramatically reduced when compared to
stud or adhesive mounts.
Magnetic mounts are available with flat surfaces for flat locations or two pole
configurations for curved surfaces. Ensuring the magnet is firmly attached is vital for
good measurements.
Adhesive Mounting
If you cannot tap a hole properly into the machine, an adhesive mount is
recommended. The rigidity of an adhesive mount is very dependent on the suitability
of the adhesive used for the environment and whether it has been applied in
accordance to the manufacturer’s instructions. The SKF Wireless Sensor wireless
condition monitoring node needs to be grounded to the machine; therefore, a
conductive adhesive must be used.
Mounting Pads
When using an adhesive, you may directly attach the sensor to the machine or onto
an adhesive mounting pad. Use of an adhesive mounting pad is recommended if
repeated removal of the sensor is required. After the pad is adhered to the machine,
the sensor is torqued onto the stud. Apply a coupling fluid to the stud face that
mates with the sensor.
The sensor case must be grounded to the machine and the installer
must ensure that the adhesive mounting pad is electrically
grounded to the machine.
Threaded Studs
The use of stud mounting results in the widest frequency measurement range. It is
recommended for permanent monitoring systems, high frequency testing, and harsh
environments.
The mounting point on the structure should be spot-faced to 1 in. diameter; the
mounting face of the sensor is 24 mm (0.945 in.) in diameter. The surface should
be flat within 25 μm (0.001 in.) and have surface texture no greater than 0.8 μm (32
μin.). The tapped hole must be perpendicular to the mounting surface and at least
two threads deeper than the stud. This will prevent a gap between the sensor and
the mounting surface, and produce optimum frequency response.
Proper screw torque on the mounting stud is also required. Under-torque of the
sensor reduces the stiffness of the coupling. Over-torque can cause permanent
thread damage to the sensor.
It is recommended to use a thread adhesive such as Loctite 222.
Installation of the SKF Wireless Machine Condition Sensor
Mounting Requirements
SKF Wireless Machine Condition Sensor Network 3
System Setup Guide
Pipe Thread Adapters
Pipe thread mounting adapters provide a mounting location for either magnetically
mounted or permanently mounted sensors, but avoid the need to drill a hole in the
machine and spot-face. They can make use of existing plugged holes on the
machine.
Securing the SKF Wireless Sensor to the Machine Surface
You must mount the SKF Wireless Sensor so that it is grounded to the machine. If
using mounting pads that are adhesively mounted onto a machine, then the adhesive
used must be conductive. If a coupling fluid is used between the machine or
mounting pad and the sensor, then we recommend the fluid to be conductive (even
though the stud itself will make an electrical coupling to the machine or mounting
pad).
Mounting Torque
Recommended SKF Wireless Machine Condition Sensor mounting torque: 2.9
Nm
