The collection of scalar value data from wireless sensors on a machine is automated by the portal application. This article discusses how to establish the timing of this collection, especially as it relates to multiple sensors on a single asset.
Setting Collection Time of Day
Wireless vibration sensors capture a range of scalar data each hour as an automated routine. The hourly timer is set when the vibration sensor is powered on and will automatically trigger to capture the scalar data every 60 minutes.
Synchronizing Scalar for Locations on Asset
If an asset has multiple vibration sensors installed, as common for machines with multiple components of the machine train, it may be beneficial to have all scalar data captured at roughly the same time. The value of this would be to capture random events or for validating the machine is in a running state before capturing the daily diagnostic data. See Configuration: Is-running threshold settings.
Aside from physically using the power button on each sensor, the scalar timer can be manipulated by using the disable / enable collection function of the PredictivePortal. To do this:
- Open the System Configuration section of the PredictivePortal.
- Identify the sensors of interest from the Online Systems tab.
- Click the ellipsis at the right end of for each sensor.
- Click "Reboot".
- Repeat steps 2-4, for each sensor associated with the machine.
- Allow the system to recover from the change. Note: it is common to miss one scalar capture as the system sends the new time for collection.
An alternative method is to use the "Disable collection", wait a couple minutes for system to respond, and then "Enable collection" from the configuration ellipsis shown above. Another method is to power off each sensor from the physical button and then powering them back on at roughly the same time. See Sensor: Powering On/OFF & LED Indications
