1.3 Considerations
General
Electrical vibration sensors, such as accelerometers, produce low-level signals proportional
to their sensed vibration. With simple HART configuration, the monitor converts the low-
level sensor signal to a wireless-enabled signal.
Commissioning
The monitor can be commissioned before or after installation. You can commission it on
the bench before installation to ensure proper operation and to be familiar with its
functions.
Make sure the instruments are installed in accordance with applicable field wiring
practices.
The AMS Wireless Vibration Monitor is powered whenever the battery is installed.
Installation
When choosing an installation location and position, provide ample access to the monitor.
The device should be mounted vertically, perpendicular to the shaft and on the bearing
case. Horizontal mounting is also an option. For more information, see Install the AMS
Wireless Vibration Monitor.
Battery
The AMS Wireless Vibration Monitor uses an off-the-shelf Tadiran TL-4920/VE battery.
The battery comes with the device but it is not connected when the device is shipped. You
need to connect the battery before configuring and installing the device.
Environmental
The monitor operates within specifications for ambient temperatures between –40°F and
185°F (–40°C and 85°C).
Verify that the operating environment of the monitor is consistent with the appropriate
hazardous location certifications.
1.4 Return of materials
You may need to ship the device to an Emerson Product Service Center for return or
replacement in case of warranty issues. Before shipping, contact Emerson Product Support
to obtain a Return Materials Authorization (RMA) number and receive additional
instructions.

Communicator.
5. Mount the cover and then tighten it.
To avoid depleting the battery, disconnect it when the device is not in use. If you
have configured the device and network but are not ready to commission it,
remove the battery to extend its operating life.
2.1.2 Configuration overview
Note
The specific user interface for performing the configuration varies depending on the host
used. To view the default values, see Configuration defaults.
Procedure
1. Connect to a wired HART interface.
You need to connect to a wired connection to set the wireless credentials.
2. Set the wireless network credentials (Network ID and Join Key) using wired
connection.
The monitor has a default Network ID and Join Key. You can change the network
credentials in the gateway that you used for configuration. All devices should join
the network once the battery is connected.
After the device has joined the network, you can complete the rest of the
configuration steps over a wireless connection.
3.
(Optional) Name the device (Tag and Device Description).
By default, the tag is VXAABBCC, where AABBCC: is the unique device ID.. The
device joins the network and operates correctly even if no changes are made, but it
is recommended to name the device something meaningful for the specific
application.
4. Specify the units (English, metric, or SI) that will be used for each parameter.
By default, units are set to English, unless the device is shipped to Japan.
User Guide Configuration

5. Specify which measurements (velocity, temperature, etc.) correspond to the
process variables PV, SV, TV, and QV. Specify the units (English, metric, or SI)
for each parameter.
By default, PV corresponds to Z-axis overall, SV is X-axis overall, TV is Y-axis overall,
and QV is Z-axis PeakVue.
6. Specify alert levels.
Determine the thresholds at which measurement alerts will display and determine
the behavior of device alerts. See the alert limits in Device variable alert limits
7. Specify the update rate.
The default update rate is once every 60 minutes. A faster update rate is not
recommended as it significantly reduces battery life.
8. Configure trending of parameters.
You can trend parameters in multiple locations such as in a plant historian, in AMS
Machine Works, and in a DCS control system.
