Ubisense Industrial Tags and Multi-mode Tags

Ubisense Industrial Tags and Ubisense Multi-mode Tags are devices that you can use to locate your assets such as vehicles, in real-time.

Industrial Tags

Industrial Tags are mechanically strong and resistant to dust and water. You can use these tags in harsh environments such as car manufacturing units.

After you attach an Industrial tag to an asset, the asset can be located to an accuracy of up to 15 cm in either 2D or 3D, in real-time.

Multi-mode Tags

Multi-mode Tags are designed for use in situations where the tag must be tracked both indoors and outdoors. Outdoors the tag is located through the use of GPS.

Suitably-configured Ubisense sensors, detector sensors or the discontinued Ubisense 2.4 GHz Receivers (UBIPRES24) are needed to receive the 2.4 GHz uplink transmission from the tag that contains the GPS location.

Attaching Tags

You can securely attach the tags to your host assets, by using a variety of attachment options, depending on:

• The type of host asset on which you are mounting the tag.
• The environment in which the tags are likely to be used.

Features of Industrial Tags and Multi-mode Tags

The features of Industrial Tags and Multi-mode Tags, are shown in the following figure.

Features of Industrial Tags and Multi-mode Tags

Feature	Description
A. Button	The button enables you to activate the tag from the deep sleep state.
B. Magnet Point	Instead of a button, an Industrial Tag can be supplied with a magnet activated switch.  To activate a tag of this type, hold the magnet against the magnet point. The correct position may depend on the strength and polarity of the magnet being used to activate the tag.
C. Mounting holes	The tag has four mounting holes. The diameter of each hole is 4.3 mm. You can connect the tag to either a universal mounting bracket, or a custom mounting bracket.
D. Strapping slots	You can also mount the tag by using straps. The strapping apertures have the following dimensions: Length: 19.5 mm Width: 4 mm
E. LEDs	The tag has three LEDs, which flash when the tag is active. The Green LED flashes to indicate that the tag is operating correctly, and the tag is communicating with the DIMENSION4 Real-time Location System.

Additional features of the Multi-mode Tag

The Multi-mode Tag incorporates a GPS receiver.

Activating Industrial Tags and Multi-mode Tags

To ensure that the tags do not use batteries unnecessarily, Industrial Tags and Multi-mode Tags are supplied in the deep sleep (deactivated) state.

Before you use a tag for the first time, it must be woken up (activated) from the deep sleep state.

To activate a tag:

1. Do one of the following:

   • Tags with buttons: Press and hold the button on the tag.

   • Buttonless tags: Hold the magnet against the magnet point on the tag case.

   The three LEDs light up and remain brightly lit for as long as you press the button.

2. Do one of the following:

   • Tags with buttons: Release the button.

   • Buttonless tags: Remove the magnet from the magnet point.

   The green LED blinks brightly and then starts to blink at a lower intensity, at regular intervals. The tag is now activated and ready to be used.

Putting an Industrial Tag or Multi-mode Tag into Deep Sleep

If an Industrial Tag or Multi-mode Tag is activated, you can put it back into the deep sleep state, to preserve battery life.

It is not possible to accidentally put a tag into deep sleep because the tag sets a 'challenge' and expects a 'response'. The LED will blink one or more times and you respond by pressing the button or swiping the magnet on the tag the same number of times. The tag then repeats the challenge and you respond again. After the second challenge and a successful response, the LED blinks brighter than normal and then switches off indicating the tag is now in deep sleep.

Putting a Tag into a Deep Sleep

To put a tag into the deep sleep state:

1. Hold down the button on the tag or hold the magnet against the magnet point.

   You may need to offset the magnet against the magnet point (see Features of Industrial Tags and Multi-mode Tags).
2. The LED first stops blinking in readiness for the first challenge. It then starts blinking again.
   1. Count the number of times the LED blinks brightly. This can be from one to five blinks.
   2. Press the button on the tag or swipe the magnet against the magnet point the same number of times.
3. Carry out the second challenge:
   1. Count the number of times the LED blinks brightly.
   2. Press the button on the tag or swipe the magnet the same number of times.

4. If you are successful, the LED blinks brightly and switches off. The tag is now deactivated.

   If you are unsuccessful, the green LED on the tag will continue to blink at a lower intensity, at the programmed UWB beacon rate.

Testing Whether a Tag is in Deep Sleep

You can check whether an Industrial Tag or a Multi-mode Tag is in a deep sleep by, pressing the button on the tag, or holding the magnet against the magnet point, for a few seconds.

You need to drill two holes through the bracket backing plate corresponding to the screw holes in the Universal Mounting Bracket to allow a bolt to be used.

Replacing the Battery of Industrial Tags and Multi-mode Tags

This procedure explains how to replace the batteries of Ubisense Industrial Tags and Multi-mode Tags.

Prerequisites

Before you begin, ensure that you have the following tools and components:

• M3 Torx variable torque screwdriver (manual or electric), set to a torque of 0.8 Nm.

• Tadiran™ TL-2770 3.6 V Size-C (8.5Ah) Lithium Thionyl Chloride batteries. More information about Tadiran batteries is available at: http://www.tadiranbatteries.de/pdf/lithium-thionyl-chloride-batteries/SL-2770.pdf.

• Electrolube™ SOB01K contact treatment Oil 2X.

• A Metcal AC-YS4 Sponge.

• AF-SBU000 safebuds.

Precautions

When replacing the battery of an Industrial Tag or Multi-mode Tag, ensure that you:

• Take anti-static precautions for dismantling and reassembling tag.

• Follow the Health and Safety (H&S) procedures and use appropriate protection, for example, wear eye protection and gloves.

Process

The process for replacing the battery of an Industrial Tag or Multi-mode Tag, is shown in the following figure.

Battery Replacement Process

You can replace the battery either with:

• An individual operator performing all the steps.

• A number of operators, each performing particular tasks described in the process.

Dismantling the Industrial Tag or Multi-mode Tag

To dismantle an Industrial Tag or Multi-mode Tag:

1. Place the tag upside down. You should be able to see the large Ubisense CE label.

2. By using an electric screwdriver, remove the four 3 x10 mm Plas-Tech® screws.

   To prevent plastic swarf contamination, any plastic swarf should be cleaned off the screws if you intend to reuse them. Otherwise, the screws can be discarded and replaced. You require new stainless steel 3 x10 mm Plas-Tech® screws to reassemble the tag.

3. Carefully remove the top molding and place in a tray. When you remove the molding, you can see the module and carrier board.

4. Lift the carrier board and the old battery out of the base. Ensure that the gasket remains in place on the base molding.

5. Turn the base and top cases upside down to ensure any loose material falls out. Ensure that the gasket is placed properly when inverting the base molding.

6. Apply treatment oil to the carrier board and new battery, as described in Applying Treatment Oil to the Battery Carrier Contacts.

Applying Treatment Oil to the Battery Carrier Contacts

To prevent fretting of the battery contacts and the battery terminals, apply treatment oil to the battery carrier contacts.

We recommend that you purchase SOB01K Contact Treatment Oil 2X from Electrolube (Farnell part code 315-336). For more information about the SOB Electrolube 2X Oil, see the Technical Data Sheet available at: http://www.ulbrich-group.com/chemical-technical-products/TDS_ELECTROLUBE_SOB_2X_Contact_Treatment_Oil_eng.pdf.

This treatment oil is suitable for situations where a thin film of oil is required. You can also use the treatment oil to clean and remove any oil, grease, and dirt deposits from the contact surfaces.

Precaution: Apply Treatment Oil Only to Metal Contacts

Ensure that you apply the treatment oil to the area of the battery contact (the outside of the angled surface of the sprung clip portion) that touches the battery, shown in the following figure.

Angled Surfaces that Touch the Battery

The supplier describes various ways in which you can apply the treatment oil. However, because of the design of the battery contacts and the small area to which you must apply the treatment oil, we recommend that you use a safe bud (cotton bud), shown in the following figure.

Using a Safe Bud to Apply Treatment Oil

To apply the treatment oil:

1. Select a clean, dry area to work.

2. The Electrolube SOB01K treatment oil removes any small deposits from the battery contacts. However, if there is any hardened dirt or tarnish on the battery contacts, clean the contacts with a suitable material such as canvas, leather, cloth, hard wood, or abrasive that can absorb the oil.

3. Wet the safe bud with a small amount of the Electrolube SOB01K contact treatment oil 2X.

4. Apply the oil to both contacts in a circular motion to ensure a uniform, thin coverage.

The following figures show examples for applying the treatment oil correctly.

Correct Application of Treatment Oil	Too Much Treatment Oil Applied

Applying Treatment Oil to the Battery Terminals

To prepare the battery terminals:

1. Moisten a rectangular piece of sponge with Electrolube Contact Treatment Oil 2X. If you place a piece of paper on the moistened sponge, the paper should get slightly dampened:

   Appropriate Quantity of Oil to Apply on Sponge

2. Place the negative terminal of the battery on the sponge. To apply a thin layer of treatment oil, move the battery on the sponge in a circular motion several times:

   Apply slight pressure when moving the battery. Repeat this process by placing the positive terminal on the sponge.

   Ensure that you do not apply too much treatment oil. The following figures show examples for applying the treatment oil correctly.

   Correct Application	Too Much Treatment Oil Applied

3. Leave the battery to dry for 10 minutes.

Reassembling the Tag

To reassemble the tag:

1. Discharge the capacitors on the carrier (module), to ensure that the tag does not receive power through the retained charge from the on-board capacitors. With the battery removed, press the button on the carrier board for at least 5 seconds. This ensures the Energy Counter based RAM variables are cleared.

2. Fit a new battery and PCB.

   1. Check that the gasket is clean and undamaged.

      It is very important to remove any dust or dirt on the gasket, particularly in the groove on both sides of the gasket and around the screw holes, as this may compromise the IP rating of the tag. A good way of removing the static that attracts the dust is to blow on the gasket and the tag.

   2. Check that the gasket on the base molding is fitted correctly and adjust the fitting if necessary.

   3. Fit the new battery into the carrier, ensuring the battery contacts are centralized at both ends.

3. Fit the module to the PCB, ensuring that the antenna and the top molding sealing edges are not damaged. Also ensure that the top molding with the bar code (Tag ID) is connected with the associated programmed module.

   1. Place the carrier (with new battery) into the base molding.

      When placing the carrier, use the wooden end of a safe bud to apply a small force to the spring clip of the battery carrier.

   2. Fix the case together using four new stainless steel 3 x10 mm Plas-Tech® screws:

      

   3. Tighten the screws using an electric torque screwdriver, set to 0.8 Nm.

   4. As a final check, re-tighten the screws with a manual torque screwdriver, set to 0.8 Nm.

Disposing of Batteries

After you have replaced batteries, dispose of the old batteries according to the manufacturer’s instructions, available at: Guidelines for Disposal of Lithium Cells and Batteries.

Resetting the Battery History

After you have replaced the battery in a DIMENSION4 tag, you must reset the battery history of the tag. This enables you to:

• Clear all previous battery usage history

• Restart the battery history data collection process for the new battery

You can reset the battery history:

• If you have a license for the SmartSpace Visibility feature, on the Tag and Battery Status screen of SmartSpace Web. See Resetting Battery Status on the SmartSpace website.

• For tags which have been associated with a SmartSpace object, in SmartSpace Config on the TAG ASSOCIATION tab.

• By using the command-line tool ubisense_tag_battery_replaced and specifying the <tag> ID

  For example:

  ubisense_tag_battery_replaced 00:11:ce:00:00:De:ad:Be:ef

  Or, by running ubisense_tag_battery_replaced without the <tag> argument and reading tag IDs from standard input

Note: This tool was introduced with version 3.6 and replaces the use of the ubisense_battery_monitor_config command-line tool in earlier 1.x versions.
