YD260 wireless sensor setup and operation
V1.50 instructions for the wireless sensor, receiver, monitoring software, sensor groups, history and alarms.
On this page
This article follows V1.50 dated September 15, 2020. The receiver's Ethernet-to-server function was described as still being completed; this source does not establish that it is available now. The envelope spectrum range is printed as 2.5–1 kHz and its intended lower-limit unit is unclear. Confirm these points for the supplied system.
System roles and measurements
The system consists of battery-powered wireless vibration/temperature sensors, a wireless data controller and a monitoring computer. Sensors installed on bearing housings send measurements wirelessly to the controller. The computer performs vibration calculations, displays current values and trends, stores history, generates reports and indicates abnormal vibration.
The sensor description lists piezoelectric acceleration sensing, velocity RMS and an 800-line velocity spectrum over 10 Hz–1 kHz, acceleration-envelope time-domain peak-to-peak values and an 800-line envelope spectrum, plus temperature from −50 to 120 °C. Normal status and two alarm levels are supported. Smartphone synchronization is described as a custom option.

| Envelope raw sampling rate | 25.6 kHz |
| Collection interval | 10 minutes |
| Default overall-value upload interval | 24 hours |
| Default spectrum upload interval | 24 hours |
| Alarm behavior | Upload overall values and spectrum when an alarm occurs |
| Power | Replaceable battery |

Upload intervals can be configured. Collection interval, overall-value upload interval and spectrum upload interval describe different actions; an overall-value upload does not imply that every spectrum is uploaded.
Install the receiver and interpret its indicators
Mount the controller to a pole with clamps and bolts, or fix it to a stable flat surface with screws. The source recommends mounting it as high as practicable. Obtain the connection drawing for the supplied controller because terminal positions are shown graphically rather than specified in the text.
The receiver uses USB power or an external 5 V DC supply. Its stated open line-of-sight transmission distance is 150 m, operating temperature is −20 to 60 °C, and protection is IP65 or higher. USB connects to the acquisition computer; wireless communication connects to the monitoring devices. Ethernet server communication was unfinished in this edition.
| Indicator | Expected behavior in the source |
|---|---|
| Power | Continuous green after power is connected |
| Link | Continuous green after power and a network-switch connection are present |
| Communication | On while information is exchanged with a device, off afterward |
| Status | On while software sends commands, the instrument uploads data, or information is exchanged with a monitor |
These indicators distinguish power, network link and data activity. A power indication alone does not demonstrate that sensor data is arriving.
Start the monitoring system
The illustrated startup sequence is:
- Open the online-monitoring installation software and install the server software.
- Start the server.
- Enable the sensor-to-network-server connection mode.
- Open the monitoring client and start the vibration-monitoring application.
- Enable online monitoring.
The source gives this sequence through screenshots and short captions; it does not supply an English installer command line, server-address specification or credential set. Use the installer and server settings provided for the installation.
The historical host requirements are an Intel Core i3 or higher, at least 4 GB RAM, at least 5 GB free disk space, a discrete graphics card with 1 or 2 GB memory, Windows 7 SP1 / Windows 8 / Windows 10, and DirectX 9.0c or later. These are the requirements recorded in the 2020 guide, not a statement of current operating-system support.
Manage sensors, groups and settings
Use the sensor tree's context menu to add, rename or delete a sensor, inspect its online state, assign it to a group, or clear its historical data. Group operations add, rename, move nested groups and delete groups.
Select an individual sensor before opening its configuration. The documented configurable items include upload interval, sampling rate, alarm threshold and danger threshold. The software sends settings to that selected sensor and saves the configuration. Apply values appropriate to that device's measurement and range.
Clearing historical data is a separate operation from deleting a sensor or clearing a live display. The source does not describe an undo operation for historical-data deletion.
Query history, alarms and danger records
For historical overall values, specify a start/end time or a predefined query period, then run the query. Page through the results using the same conditions and set the number of rows displayed per page. Export saves the current result page to an Excel spreadsheet.
Line charts display velocity, displacement and temperature over time. Select the desired component, such as X, Y, Z or the combined value, when that measurement is available.
Alarm and danger data use separate query views. In each view, choose the date range or period, query records, set rows per page and page through the results. Their export command also exports the current page, rather than establishing an export of every record matching the query.
Operate live monitoring
The live-monitoring view provides Start, Stop and Clear commands. Use the line plots to inspect current time-domain velocity, displacement and acceleration and select the device whose monitoring status is needed.
The guide also records configurable launch branding and application name, with other custom functions subject to agreement. These customization entries do not establish that an unspecified custom function is included in a standard installation.
