August 2020 Configuration Setup overview Unless the AMS Wireless Vibration Monitor is purchased pre-configured from the factory, it needs to be configured prior to installation at the facility or measurement location. There are three possible setups to configure the device: 1.
This setup is recommended for standard device configuration. Pre-configuration The AMS Wireless Vibration Monitor is shipped with the battery disconnected from the device to comply with safety requirements. You need to connect the battery before you can configure the device. Remove the battery after configuration to avoid depleting it.
User Guide Configuration MHM-97927-PBF August 2020 4. Replace the battery. Tuck the wires against the battery and lock them into place. 5. Mount the cover and then tighten it. Note 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.

Operation User Guide August 2020 MHM-97927-PBF Device variable ranges The device variables have the following ranges: 1. Saturated – Indicates the saturation point of the transducer. In this device, this level is not settable by the end user. When this range is violated, the device variable status is Bad.
The AMS Wireless Vibration Monitor uses (lower-frequency) Overall Velocity in conjunction with (higher-frequency) PeakVue to provide a holistic solution across all frequencies while optimizing the usage of the limited power and bandwidth available in a wireless device.
Page 56
Velocity, so ensure that the measurement conditions are similar when trying to duplicate the value reported by the AMS Wireless Vibration Monitor with a handheld. The AMS Wireless Vibration Monitor uses ISO 10816, which defines a measurement bandwidth of 2 Hz to 1 kHz.
Page 57
For this reason, the AMS Wireless Vibration Monitor measures, calculates, and reports Overall Velocity in RMS, and it is necessary to multiply by 1.4142 to get the corresponding peak levels if this is the preferred format.
1.0 in/s PeakVue ™ PeakVue is a patented Emerson technology that is very useful for isolating high- frequency phenomena associated with developing faults, especially in rolling-element bearings. The premise for PeakVue is that the high-frequency components are not readily detected with more conventional measurements such as Overall Velocity, low-frequency energy (LFE), or digital overall.
Page 59
For frequent automated monitoring, such as that offered by the AMS Wireless Vibration Monitor, the levels can be increased for most balance of plant equipment running between 900 and 4000 RPM. You can use the "rule of tens" as a simple but effective approach to monitoring PeakVue on most rolling element bearing machines.
