Metso WearSense Hugger Sensor R6.x User Manual – WearSense Hugger Sensor R5.x User Manual
Introduction
Thank you for choosing the WearSense Hugger Sensor. This user manual provides instructions on how to effectively use and maintain the sensor.
The sensor is designed to be used in conjunction with the WearSense portal, where the data can be viewed and interacted with.
Getting Started
Sensor Attachment
Attach the sensor to the chute liner by either securing it to a fastener or directly screwing it into the asset. Ensure a secure attachment for accurate measurements, as vibrations may cause it to loosen over time.
Do not over tighten the fastening to prevent damage to the sensor.
Commissioning
After installing the sensor into an asset part, record the serial number and location on the corresponding arrangement drawing. Contact the WearSense support team with this information to reflect the commissioning into the WearSense portal.
Operation
Normal Operation
Normal operation for the sensor involves waking up periodically, take one or more measurements (depending on settings), attempt to send this data back to a nearby gateway, and finally return to sleep.
| Measurement | Default Period |
| Wear Depth | Every 6 hours |
| Vibration (3-axis) | Every 6 hours |
| Orientation | Every 6 hours |
These defaults can be changed by contacting the WearSense support team. These measurement intervals are individually tracked, meaning the sensor may wake up faster than expected since the last time it woke up.
Forced Wake Up
The sensor includes a magnetic switch that can be activated by swiping a magnet briefly over the body. Activating this switch will cause the sensor to wake up immediately and perform a measurement instantly (for each configured).
Be careful not to hold it over the switch for longer than a few seconds, as doing so will switch this functionality off and the WearSense support team will need to reset it. This automatic magnetic switch disabling is provided for use in magnetic environments in order to prevent erratic measurement periods and reduction of battery life.
Status Indications
The sensor includes a transparent window in which a colored status indicator can be seen.
Upon wakeup, a short green pulse will always be shown.
Upon going back to sleep, a final status indication will be shown, summarized in the following table.
| Status Indication Pattern | Meaning |
| Short green pulse | Measurement(s) were taken successfully, and communicated with gateway successfully. |
| Short red pulse | No gateway could not be communicated with. History storage will be used if available and measurement(s) were taken successfully. |
| 2 short red pulses | Communications successful with gateway, however there was a problem performing the wear depth measurement. |
| 3 short red pulses | Communications successful with gateway, however there was a problem performing a measurement other than the wear depth, for example, vibration measurement. |
History Storage
The sensor includes a small history storage area, which can be used to store wear depth measurements.
Approximately 100 measurements can be stored.
The history storage is used when the following conditions are met:
- The gateway could not be communicated with.
- The history storage interval has passed.
- Optionally, only stored whenever the wear depth measurement has changed since the last one.
- The history storage is not full, or optionally, an overwriting strategy is set (such as overwrite oldest).
Other measurement types are not currently supported.
Contact the WearSense support team for help with this feature.
Troubleshooting
Please contact the WearSense support team for help with issues listed below.
Communication failure with gateway
- While the gateway is communicating with another sensor, a temporary failure is expected. Try again later.
- Ensure the gateway is operating normally.
- Ensure there is sufficient wireless range. Try moving the sensor closer to the receiver antenna.
Objects obstructing the line of sight, especially metalic ones, will reduce the effective range.
- The internal battery may be going flat.
Data for one or more measurements is not working or incorrect
- The sensor settings may be incorrect.
- The sensor may be faulty and needs replacing.
History storage not working
- The sensor settings may be incorrectly set.
- The history storage may be full and cannot store anymore data.
Magnetic switch not working
- The magnetic switch functionality has been disabled and needs to be switched back on.
Decomissioning & Disposal
When the asset part the sensor resides in is replaced, the sensor should be removed and decomissioned from the WearSense portal at the date of removal. Contact the WearSense support team for assistance with this.
As the sensor contains a lithium battery, please follow the appropriate regulations and guidelines set out by your local authorities or waste management facilities.
Do not dispose of the device or battery in regular household waste.
Safety
This product is only intended for use in restricted access areas and installed by trained personnel.
This product is only for use in locations where children are not likely to be present.
